Detached Home Inspection in Calgary: The Complete Guide

Detached homes are the most common type of property I inspect in Calgary. Unlike a condo or townhome where scope is limited by shared walls and common areas, a detached home inspection covers everything — from the roof ridge down to the foundation, and every system in between.

If you are buying a detached or semi-detached home in Calgary, here is what the inspection involves, what I typically find, and why the age and size of the home matter more than you might expect.

What a Detached Home Inspection Covers

A detached home gives me full access to every system and component. There is no condo board responsible for the roof and no party wall limiting what I can check. That complete scope is why detached home inspections are the most thorough type I do.

Here is what I inspect:

Full roof. Shingles, flashing, vents, chimney, and any roof penetrations. I get up on the roof when it is safe to do so and check every section. In Calgary, roofs take a beating from hail, chinook winds, and freeze-thaw cycles, so this portion of the inspection is critical.

All exterior walls. Siding, stucco, trim, caulking, and weather barriers. I check for damage, deterioration, and signs of moisture intrusion.

Full foundation. Visible foundation walls from the interior and exterior, looking for cracks, movement, moisture, and structural concerns. Calgary’s clay soil makes foundation assessment especially important.

Full attic and crawlspace. Insulation levels, ventilation, structure, and any signs of moisture or pest activity. I get into these spaces because problems hide there.

Grading, drainage, and lot. How water moves around the property matters. I check the slope of the grade, downspout discharge, window wells, and any areas where water pools or directs toward the foundation.

All interior systems. Plumbing supply and drainage, electrical panel and distribution, HVAC including furnace, air conditioning, and humidifier. I test water pressure, check every outlet, verify GFCI protection, and assess the condition of every major system.

Garage. Structure, door and opener, fire separation to the house, and ventilation.

Windows and doors. Every window and exterior door gets checked for operation, sealing, and condition.

Appliances. I run the dishwasher, check the range, and test any built-in appliances.

My flat-rate pricing for detached and semi-detached homes ranges from $450 to $650 depending on size, with GST included. Every inspection comes with thermal imaging, moisture testing, and gas detection at no extra charge. You can see the full breakdown on my pricing page.

Why Size Matters

A bigger home has more of everything. More roofing, more plumbing, more electrical outlets, more windows, more rooms, more places for problems to develop. A 2,800-square-foot two-storey takes meaningfully longer to inspect than a 1,000-square-foot bungalow, and that time difference is reflected in the price.

My pricing tiers scale with size for exactly this reason. A smaller detached home starts at $450, while a larger one closer to 3,000 square feet is $650. Homes over 3,000 square feet need a custom quote because the scope and time involved vary too much to standardize.

Why Age Matters

The age of a Calgary home changes the entire character of the inspection. Here is what I typically see across different eras.

Pre-1970s Homes

Calgary’s oldest residential areas — places like Ramsay, Inglewood, Bowness, and Mount Pleasant — have homes that were built with materials and methods that are simply different from what builders use today. I regularly find:

• Knob-and-tube wiring or early copper wiring without a ground
• Galvanized steel plumbing that corrodes from the inside and restricts water flow over decades
• Foundation movement from sixty-plus years of Calgary’s clay soil expanding and contracting
• Layers of renovations from different decades, not always done to code
• Asbestos-containing materials in insulation, flooring, and pipe wrap

These homes have character, but they require careful evaluation. If you are looking at an older Calgary home, my post on inspecting older homes goes deeper into what to expect.

1970s to 1990s Homes

The suburban expansion era brought a wave of homes across communities like Lake Bonavista, Woodbine, Shawnessy, and Riverbend. Common findings from this period include:

• Aluminum wiring in some 1970s homes, which requires specific outlets and connections
• Polybutylene plumbing that is prone to brittleness and failure at fittings
• Older furnaces approaching or past their expected lifespan
• Original windows that have lost their seal and no longer insulate effectively
• Basement finishing done by homeowners without permits or inspections

2000s to Present

Newer homes in communities like Mahogany, Seton, Cornerstone, and Legacy are generally in better shape, but they are not without issues. I commonly find:

• Grading and drainage problems on newer lots where the landscaping has not fully settled
• Builder deficiencies — minor issues the builder should have caught during warranty
• Cosmetic quality over structural substance — some builders prioritize finishes over fundamentals
• Roof and siding installation shortcuts that may not show up for several years

Newer does not mean perfect. It just means the problems tend to be different.

Calgary-Specific Concerns

Calgary’s climate and geography create conditions that affect homes in ways unique to this region.

Freeze-thaw foundation cracks. Water enters small cracks in the foundation, freezes, expands, and makes the crack bigger. Over years, this cycle can turn a hairline crack into a structural concern. I check every visible foundation surface for this.

Chinook wind roof damage. Those dramatic warm winter winds create rapid temperature swings that lift, curl, and break shingles. A roof that looks fine from the street can have significant wind damage when you get up close.

Hail damage. Calgary has a well-earned reputation for hailstorms. I check roofing, siding, window screens, and any exposed components for impact damage. Some of it is from years ago and was never repaired.

Clay soil movement. Much of Calgary sits on expansive clay that swells when wet and shrinks when dry. This causes foundations to shift, floors to become uneven, and doors to stick. Understanding what is normal seasonal movement versus a structural problem takes local experience.

Ice damming. In winters with heavy snow followed by warm chinook days, ice dams can form along roof edges. These push water back under the shingles and into the attic or walls. I use thermal imaging to identify areas of heat loss that contribute to ice damming.

Common Red Flags I Find

Across all ages and styles of detached homes in Calgary, certain red flags show up more than others:

• Roof damage that the seller may not be aware of
• Foundation cracks that have been cosmetically patched but are still active
• Electrical panels that are undersized or have known safety issues
• Plumbing materials approaching failure age
• Moisture in basements from poor grading or failed weeping tile
• Furnaces or hot water tanks near the end of their lifespan

A pre-purchase inspection catches these before they become your problem.

What You Get for Your Money

My detached home inspections are priced from $450 to $650 based on size, with GST included. Every inspection includes thermal imaging, moisture testing, and gas detection.

You get two and a half to four hours on-site, a detailed digital report with high-resolution photos and practical recommendations, a walkthrough of the most important findings before I leave, and support after the inspection if anything in the report needs clarification.
