A Note From the Team

A long report is not a bad report.
Here is how to sort it.

The first time most buyers open an inspection report, their stomach drops. There are dozens of findings, many in stern-sounding language, complete with photographs of things that look alarming. It reads like an indictment of the house.

It is not. A home inspector's job is to document everything they observe, and a thorough inspector on a well-maintained twenty-year-old Calgary home will still fill many pages. A short report usually means a superficial inspection, not a perfect house.

What the report cannot do is rank findings by how much they should matter to your decision. A missing GFCI outlet and a cracked heat exchanger can sit two lines apart in the same section. One is a twenty-minute fix; the other is a furnace replacement and a carbon monoxide risk.

What You
Are Reading

What an inspection covers, the four categories every finding falls into, and what is normal for each Calgary era.

Calgary Listings Group
Chapter 01

What an Inspection Is — And What It Isn't

Visual, Non-Invasive, and of That Day

Your inspector examines what is accessible and visible. They do not open walls, lift flooring, excavate the yard, dismantle appliances, or move the seller's stored belongings out of the way. If a wall is finished, whatever is behind it stays unknown. If the crawlspace is blocked, it may go uninspected — and the report will say so.

It Is Not a Warranty or a Pass/Fail

An inspection is not a guarantee that nothing will break. A furnace can pass inspection in March and fail in November. The report describes condition on the day, not future performance, and there is no threshold at which a home “passes.”

It Is Not a Code Inspection

Homes are generally required to meet the code in force when they were built, not today's. Your inspector may flag that something would not be built that way now — older railing spacing, an ungrounded outlet, a low handrail. That is useful context, not a defect the seller must correct.

What It Genuinely Gives You

An informed picture of the major systems and their remaining life, identification of safety issues, evidence of past or ongoing water problems, and a maintenance roadmap for your first five years of ownership. That last one is worth the fee on its own, and almost nobody uses it.

Inspectors Do Not
Open walls or lift flooring
Move stored belongings
Dig up buried lines or tanks
Test for mould, asbestos, or radon (unless added)
Predict when something will fail
Add-Ons Worth Buying
Sewer camera scope — older homes, mature trees
Radon screening test
Thermal imaging for moisture
Specialist referral on anything structural
Report Language
“Monitor,” “recommend further evaluation,” and “typical for age” each mean something specific. “Further evaluation” means the inspector reached the limit of what they can determine — take it seriously.
Chapter 02

The Four Categories — How to Sort Any Finding

1. Safety

Anything that could hurt someone: a cracked furnace heat exchanger, exposed or double-tapped wiring, missing smoke and CO alarms, an unstable deck or railing, a gas leak, water at the electrical panel. These get addressed regardless of price and regardless of who pays. They are also the findings most likely to get a seller's genuine attention.

2. Major Systems Near End of Life

The furnace, roof, hot water tank, electrical panel, windows, and foundation. These are not defects — they are the expensive parts of a house with a finite lifespan. A 22-year-old furnace is not broken, but you should be budgeting for it. This is the category that most changes what the home really costs you, and the one buyers most often overlook because nothing is technically wrong.

3. Deferred Maintenance

Work that should have been done and was not: failed caulking, negative grading against the foundation, disconnected downspouts, a plugged dryer vent, an unserviced furnace. Individually minor, and cheap to fix — but a house with a lot of it is telling you how it has been cared for, which is a signal about everything you cannot see.

4. Cosmetic

Scuffed paint, a stained carpet, a cabinet door out of alignment, a cracked tile. You saw the house. These are not surprises and they are not negotiating material.

⚠️ Category 1 — Act
Cracked heat exchanger
Exposed or improper wiring
No CO alarms with gas appliances
Structural movement
Water near the electrical panel
Category 2 — Budget
Furnace over 18 years
Roof over 18 years
Hot water tank over 10 years
Original windows in a 1970s home
60-amp service or fuse panel
Categories 3 & 4
Fix category 3 in your first year — grading and drainage first. Category 4 is decorating, and it is yours now.
Chapter 03

What's Normal by Build Era — Calgary Housing Stock

Pre-1960

Expect knob-and-tube remnants, 60-amp service, cast iron or clay drains worth scoping, asbestos in stipple ceilings and pipe wrap, and original single-pane or early double-glazed windows. Foundations are often unreinforced concrete or block — efflorescence and minor cracking are common; horizontal cracking is not, and needs an engineer.

1960s–1970s

The aluminum wiring era in parts of Calgary, and a common insurance obstacle. Vermiculite attic insulation appears here and should be treated as asbestos-containing until tested. Panels of this age are often at capacity for modern loads.

1978–1995

The Poly-B window. Grey plastic supply plumbing that degrades from the inside and fails at the fittings — a leading Calgary insurance issue and a $8,000–$15,000 repipe. Check for it specifically in this range. Some homes in this era still carried aluminum wiring into the early 1980s.

1995–2010

Generally sound construction. Watch for original furnaces and hot water tanks now at end of life, first-generation Poly-B carryover at the early end, attic ventilation issues showing up as ice damming, and builder-grade windows starting to fail their seals.

2010 and Newer

Tight, efficient envelopes — and therefore higher radon readings and more indoor humidity issues. Look for condensation on windows, bathroom fans venting into attics rather than outside, and grading and drainage still settling on newer lots. Confirm the radon rough-in and whether it was ever activated.

⚠️ Insurance Flags
Poly-B (1978–1995)
Aluminum wiring (1960s–early 80s)
Knob-and-tube (pre-1950)
Roof past 20 years
60-amp service or fuse panel
Always Worth Scoping
Homes before about 1970 with mature trees on the lot. Root intrusion into clay drain tile is common in Calgary's older communities and a $8,000–$25,000 surprise after possession.
New Builds Too
Radon rough-in — activated or capped?
Bath fans venting outside, not to the attic
Grading still settling
Window condensation and humidity
Chapter 04

Choosing the Inspector — Licensed, Local and Thorough

The report is only as good as the person who wrote it. In Alberta inspectors are licensed, but licensing is a floor, not a guarantee.

Licensed in Alberta

Home inspectors in Alberta must hold a licence under the province's consumer protection rules and carry insurance. Ask for the licence number and check it. An unlicensed inspection is not just risky; it may be worthless if a dispute follows.

Local experience

Calgary's housing stock has its own habits: specific builders, specific decades, specific soils. An inspector who has walked a thousand local basements knows which cracks are settlement and which are movement. Ask how long they have worked here and what they see most.

Time on site

A proper inspection of a detached home takes hours, not a lunch break. Ask how long they allow, whether they go on the roof and into the attic, and whether they run every appliance and fixture. The answers tell you what kind of report you will get.

Tools and extras

Thermal imaging, moisture meters and a sewer camera scope are not standard everywhere. Ask what is included and what costs extra. A sewer scope on an older home is money well spent in a city with clay soil and mature trees.

Book Early
Good inspectors are booked days ahead, and your condition period is short. Ask us for the names we trust the day your offer is accepted, or before.
Chapter 05

Attending the Inspection — What to Watch and Ask

Chapter one said to go. This chapter is what to do while you are there, so the hours translate into understanding rather than a stack of photos.

Follow, do not lead

Let the inspector work their sequence; they are systematic for a reason. Stay close, listen, and save questions for the natural pauses. The best inspectors narrate as they go, and that narration is the real report.

The three questions

For anything flagged: how serious is it, how soon does it need attention, and roughly what does it take to fix. The written report will sort findings into categories, but the inspector's tone in the moment tells you which ones they actually worry about.

Learn the home

Where the main water shutoff is, the electrical panel, the furnace filter, the sump if there is one, the cleanouts, the gas shutoff. Buyers who learn this on inspection day are homeowners who can act in an emergency.

Photograph your own

The inspector's photos go in the report. Take your own of the mechanical room, the attic hatch, the panel and anything you may want to show a contractor later. You will not have this access again before possession.

“The report is the summary. The three hours on site are the education.”
— Calgary Listings Group
Chapter 06

Foundations, Grading and Water — The Calgary Chapter

If one subject dominates inspections in this city, it is water: where it goes, where it should not, and what the ground does when it is wet.

Clay and movement

Much of Calgary sits on clay that swells when wet and shrinks when dry. Foundations move with it, and the hairline vertical cracks in poured concrete walls are usually that movement. Horizontal cracks, bowing, or cracks that are wider at one end are a different conversation, and the inspector will say so.

Grading and downspouts

The ground should slope away from the foundation on every side, and downspouts should discharge well away from the wall. Negative grading and short downspouts are the most common findings in the city and among the cheapest to fix, and they are the cause of a large share of basement water complaints.

Window wells and weeping tile

Window wells that collect debris and lack drainage are a basement leak waiting for a thunderstorm. Older homes may have clay weeping tile that has collapsed; the symptom is seasonal dampness at the base of the walls.

Sump pumps and backwater valves

Not every Calgary home has them, and some areas need them more than others. A sump that runs constantly, or a backwater valve that has never been serviced, is worth a specialist's look before conditions are removed.

Look After Rain
If you can, view the basement after a heavy rain or a big melt. Staining tells you about the past; dampness tells you about now.
Part Two

Costs and
Leverage

Real Calgary numbers, what justifies renegotiating, and how to turn the report into a five-year plan.

Calgary Listings Group
Chapter 07

What Things Actually Cost — Calgary Figures

The Big Numbers

Full roof replacement on a typical Calgary detached home runs $8,000–$20,000 depending on size and material. A high-efficiency furnace replacement is $5,000–$9,000. A Poly-B repipe is $8,000–$15,000. Electrical service upgrade from 60 or 100 amp to 200 amp runs $3,000–$6,000. Full window replacement on a mid-sized home can reach $15,000–$40,000.

The Middle Range

Hot water tank $1,800–$3,500. Radon mitigation $1,500–$3,500. Regrading and drainage correction around a foundation $2,000–$8,000. Attic insulation top-up $2,000–$4,500. Sewer line repair, depending on depth and access, $8,000–$25,000.

The Cheap Fixes That Sound Frightening

GFCI outlets $150–$300 each installed. Smoke and CO alarms under $200. Downspout extensions under $100. Dryer vent cleaning $150–$250. Furnace service $150–$250. Caulking and minor sealing, a weekend. A long list of these is a maintenance to-do, not a reason to renegotiate.

Get a Real Quote Before You Ask

If you intend to raise something with the seller, get a written contractor quote inside your condition period. “The inspector says the furnace is old” is an opinion. A dated quote for $7,400 is a number, and numbers move sellers.

$5,000+
Roof replacement: $8K–$20K
Furnace: $5K–$9K
Poly-B repipe: $8K–$15K
Sewer line: $8K–$25K
Windows: $15K–$40K
$1,000–$5,000
Hot water tank: $1.8K–$3.5K
Radon mitigation: $1.5K–$3.5K
Regrading: $2K–$8K
Attic insulation: $2K–$4.5K
Panel upgrade: $3K–$6K
Under $500

Chapter 08

What Justifies Renegotiating — An Honest Read

The Test

Ask one question of any finding: would this have changed the offer I wrote if I had known? A $12,000 sewer repair would have. A missing GFCI would not have. That single question sorts almost every item correctly.

Strong Grounds

Safety defects. Significant, previously invisible problems — a failed sewer line, a cracked heat exchanger, active water penetration, structural movement. Anything that makes the home difficult or expensive to insure. And anything that contradicts what was represented on the listing or the property disclosure statement.

Weak Grounds

Age. A twenty-year-old roof on a twenty-year-old house is not a defect — it is a twenty-year-old house, and the price already reflects it. The same goes for a long list of small maintenance items, anything you could plainly see when you viewed, and anything that would not be built to today's code but was fine when built.

How to Ask

Pick the one or two items that genuinely matter. Attach a written quote. Ask for a price adjustment rather than repairs where you can — a seller doing last-minute work has every incentive to do it cheaply, and you inherit it. Give the seller a specific number and a reason.

Chapter 08

What Justifies Renegotiating — An Honest Read (continued)

Know Your Position

Leverage depends on the market and on the deal. If you were one of five offers last week, an aggressive request may simply end the transaction — the seller has a list of buyers. If the home has been on for ninety days, you have room. We will tell you which situation you are in, including when the honest answer is that you should absorb the finding and buy the house.

Chapter 09

After the Report — Turn It Into a Plan

Build the Five-Year Budget

Go through the report and write down every major system with its age and expected remaining life. A 16-year-old furnace, a 14-year-old roof, an 8-year-old hot water tank. Now you know roughly what is coming and when — and you can set aside money instead of being ambushed.

Do the Cheap Preventive Work First

Grading and drainage before anything else. Most expensive Calgary basement problems begin as water sitting against a foundation, and correcting slope and extending downspouts is inexpensive. Then service the furnace, clean the dryer vent, seal what needs sealing.

Keep the Report

File it with your home records. It is a dated baseline of condition, and it is genuinely useful years later — when you sell, when you make an insurance claim, or when you are trying to remember whether that crack was there when you bought.

Book the Things Only You Can Do Now

Start a long-term radon test in your first heating season. Locate and label the main water shut-off and the electrical panel. Change the locks. Note the furnace filter size. These take an afternoon and they are much harder to get around to later.

First Year
Fix grading and drainage
Service the furnace
Start a 91-day radon test
Change the locks
Label shut-offs and the panel
Five-Year Budget
List every major system and its age
Subtract from typical lifespan
Set aside monthly against the nearest one
Keep on File
The full report, any specialist reports, and quotes you obtained. A dated baseline of condition is worth having when you sell.
Chapter 10

Roofs, Attics and Hail

Calgary roofs live hard: hail in summer, ice in winter, and sun at altitude the rest of the year. The inspector's roof findings deserve more attention here than almost anywhere else.

Reading the roof section

Age and remaining life are estimates based on material, wear and the visible condition. Lifted or cupped shingles, granule loss in the gutters, exposed nail heads and patched areas are the signs of a roof on its way out. Flashing at chimneys, vents and walls is where most leaks start, and the report should mention each.

Hail

Impact bruising from hail shortens a roof's life even when it does not leak. Ask the seller whether a hail claim was ever made and whether the roof was replaced after it. Insurance history matters here more than in most cities, and your own insurer may ask.

The attic

Insulation depth, ventilation and signs of moisture or past ice damming on the sheathing. A warm attic in winter is a sign of poor air sealing, and it is what produces the ice dams and icicles that damage eaves and interiors.

Skylights, chimneys and vents

Each is a hole in the roof and each has a life. A skylight with fogging between the panes has failed; a chimney with crumbling mortar or a missing cap is taking water. Both are routine findings and both have real costs.

“In this city, the roof is not a line item. It is a chapter.”
— Calgary Listings Group
Chapter 11

Furnaces, Hot Water and Ventilation

Heating is life support here for half the year. The report's mechanical section tells you how much life the equipment has and whether it is safe.

Furnace age and type

The inspector reads the data plate for the age and notes the type: an older mid-efficiency unit with a metal flue, or a high-efficiency unit venting in plastic. Age sets expectations; service history sets the real condition. Ask the seller for the last service invoice.

Safety findings

A cracked heat exchanger, flame rollout marks, a flue that is corroded or improperly connected, or a carbon monoxide reading are safety items, and they come first in any negotiation. The inspector may recommend a licensed gas fitter's evaluation; take that recommendation seriously.

Hot water tanks

Tanks have a working life, and the plate tells you where this one is. Rust at the base, a leaking relief valve or a corroded fitting are end-of-life signs. The report will note whether the venting is correct and whether an expansion tank or drain pan is present.

Ventilation and humidity

Bathroom fans that vent into the attic instead of outside, kitchen hoods that recirculate, and a home without a heat recovery ventilator are all common. They are not emergencies, but they explain the condensation on winter windows and the stains in the attic.

Ask for the Gas Fitter
If the report recommends further evaluation of the furnace, book a licensed gas fitter inside the condition period. It is a modest cost and the finding can be a large one.
Chapter 12

Electrical — From Aluminum to Panels

Electrical findings range from cosmetic to insurable-or-not. Knowing which is which keeps a routine inspection from becoming a crisis.

Aluminum branch wiring

Homes built in a certain window may have aluminum wiring to outlets and switches. It is not automatically dangerous, but connections need to be of the right type and insurers often ask about it. Expect the report to flag it and to recommend an electrician's review; expect your insurer to ask for the same.

Panels

Some panel brands and some older fuse panels are flagged by inspectors and insurers. Double-tapped breakers, missing knockouts, and a panel without room for future circuits are routine findings with routine fixes. A panel upgrade is a larger job and is usually priced into the negotiation rather than demanded.

Outlets, GFCI and grounding

Ungrounded outlets, missing ground-fault protection in kitchens and bathrooms, reversed polarity, and extension cords used as permanent wiring. Each is minor on its own and the list can be long; an electrician's half day usually clears all of them.

Knob and tube

Rare in Calgary but present in the oldest neighbourhoods. If any remains, insurers will want it removed or isolated, and the cost of a rewire belongs in the offer conversation, not the renovation budget.

“Electrical findings are either cheap or insurable-or-not. Find out which before conditions come off.”
— Calgary Listings Group
Chapter 13

Plumbing, Sewer and the Scope

Water in the walls is expensive. Water under the house is the inspection item buyers most often skip and most often regret.

Supply lines

The report notes the material: copper, PEX, galvanized steel, or a grey polybutylene pipe used for a period and now flagged by insurers. Galvanized pipe corrodes from the inside and reduces pressure; polybutylene has a failure history. Both are replace-eventually items with a price.

Drains and venting

Slow drains, gurgling fixtures and sewer smell point to venting or partial blockages. A test of every fixture running at once shows whether the system copes. S-traps, improper venting and unpermitted basement bathrooms show up here.

The sewer scope

A camera run down the main line from the cleanout to the city main. It finds root intrusion, offset joints, bellies holding water and collapsed sections. On a home older than a few decades, or on a mature street with large trees, it is the single highest-value add-on you can buy during an inspection.

Water quality and pressure

Municipal water needs no testing, but pressure that is too high or too low is worth a note, and a home with a water softener or filtration system should come with its service history and any rental contract.

Scope It
A sewer line replacement is one of the most expensive repairs a Calgary homeowner can face. The scope that finds it costs a fraction of that, once.
Questions

Inspection Report Questions

01
Is a long inspection report a bad sign?
No. A thorough inspector documents everything observed, so even a well-maintained twenty-year-old Calgary home produces pages of findings. A short report more often means a superficial inspection than a perfect house. What matters is not how many items are listed but which category they fall into: safety, major systems near end of life, deferred maintenance, or cosmetic.
02
What does a home inspection cost in Calgary?
Roughly $400 to $700 for a typical single-family home, more for large, older, or acreage properties. Useful add-ons include a sewer camera scope at $200 to $400 for older homes with mature trees, radon screening at $150 to $300, and thermal imaging. A structural engineer, if one is needed, is a separate $500 to $1,500.
03
What does 'recommend further evaluation' mean in my report?
It means the inspector has reached the limit of what a visual inspection can determine and a specialist is needed. Take it seriously — it usually appears next to the items with the widest range of possible cost, such as foundation movement, electrical concerns, or suspected water penetration. Get the specialist in while you still have condition days left.
04
Can I ask the seller to fix everything on the list?
You can ask, but it rarely works and often damages a deal that was going fine. Sellers are not obliged to fix anything. Focus on the one or two findings that genuinely would have changed your offer, attach a written contractor quote, and ask for a price adjustment rather than seller repairs — you will control the contractor and the standard of the work.
Questions

Inspection Report Questions (continued)

05
What are the most expensive surprises in Calgary homes?
Sewer line failure at $8,000 to $25,000, full window replacement at $15,000 to $40,000, a roof at $8,000 to $20,000, a Poly-B repipe at $8,000 to $15,000, and furnace replacement at $5,000 to $9,000. The sewer line is the one most worth investigating in advance, because it is invisible during a normal inspection and common in older Calgary communities with mature trees.
06
Does an old furnace or roof justify a price reduction?
Usually not on its own. A twenty-year-old roof on a twenty-year-old home is expected condition, and the market price already reflects the age of the house. What does justify a conversation is a system that has actually failed, one that is unsafe such as a cracked heat exchanger, or a system materially older than represented in the listing.
07
Should I get a sewer camera scope?
On any Calgary home built before roughly 1970, particularly with mature trees on or near the lot, yes. Older clay and cast iron drain lines are vulnerable to root intrusion and collapse, none of it visible during a standard inspection, and repairs run from $8,000 to $25,000. It costs $200 to $400 and is one of the highest-value add-ons available.
08
What should I do with the report after I move in?
Turn it into a five-year budget: list each major system with its age and remaining life so replacements are planned rather than emergencies. Do the cheap preventive work first, starting with grading and drainage, since most expensive basement problems begin as water sitting against the foundation. Then file the report — it is a dated baseline of condition that is useful when you sell or make a claim.
Questions

Inspection Report Questions (continued)

09
Can I use the seller's pre-listing inspection instead of my own?
Read it, and treat it as useful background, but have your own done. The seller's inspector worked for the seller, the report may be months old, and your lender and your lawyer will want an inspection that was done for you.
10
The inspector missed something. What can I do?
Inspection agreements limit the inspector's liability, usually to the fee. Alberta's licensing scheme gives you a complaint route, and a serious miss can be pursued, but the practical protection is choosing a thorough inspector and attending the inspection.
11
Should I inspect a brand-new home?
Yes. New homes have warranty coverage, but the warranty is easier to use when a defect is documented at possession. Many buyers also inspect again before the first-year warranty window closes.
12
What if the seller refuses to allow a sewer scope or a specialist?
Refusal is unusual and tells you something. Your condition lets you walk away if you are not satisfied, and a seller who blocks a reasonable inspection is making that decision for you.
