Seven priority checks for a pre-purchase home inspection

When you are working to meet a condition deadline, a focused pre-purchase home inspection helps you prioritise safety, structure, and cost risk so you can decide with confidence. This checklist lists seven priority checks, explains when to add drone roof or infrared thermal imaging, and shows how to use a same-day digital report to meet condition-removal timelines. Use these items to compare inspectors and to write practical condition clauses that protect your deposit.

1. Structural integrity and foundation

What to check: visible foundation cracks, stair-step cracking in masonry, sloping or uneven floors, doors and windows that stick, bowed walls, and signs of recent settlement. A home inspector documents visible movement and moisture tracking, but an inspector cannot provide an engineer's signed opinion. Expect a referral to a licensed structural engineer where movement or large cracks are observed.

Inspector versus engineer

Inspector: identifies and documents visible defects, movement patterns, and likely moisture paths with photos and location notes.
Engineer: provides a technical evaluation, measurements, and a signed report when structural instability or active movement is suspected.

Action steps

Ask the inspector to photograph and mark exact locations of concerning cracks in the same-day report and to note whether movement appears active.
If the inspector recommends an engineer, obtain that evaluation before your condition removal deadline and include timing in your purchase conditions.
Sample condition-clause wording: "Buyer may require a structural engineer assessment if the inspection identifies foundation movement or cracks exceeding typical hairline widths."

2. Roof, attic and moisture risk (use drone or thermal imaging when needed)

What to check: roof-covering condition, flashing and chimneys, attic staining or active leaks, roof ventilation, insulation depth, and signs of rot. When the roof is steep, unsafe to walk, or appears aged, add a drone roof inspection. When attic stains, inconsistent insulation, or unexplained cold spots exist, add infrared thermal imaging to detect concealed moisture, heat loss, or insulation gaps.

Drone and thermal tools increase diagnostic confidence without invasive openings. They are especially useful for steep roofs, complex rooflines, and older homes with a history of leaks or poor ventilation.

Cost versus benefit

Drone inspection: high value when roof access is unsafe or a closer look at flashing, valleys, and chimneys is required.
Thermal imaging: high value when you suspect hidden leaks, insulation gaps, or moisture behind finishes, since it can reveal temperature anomalies non-invasively.

Sample condition clause

"Buyer may require a drone roof inspection and infrared thermal scan if the pre-purchase inspection identifies roof wear, attic staining, or suspected concealed moisture."

For background on why inspections matter before purchase see the Government of Canada guidance on home inspections.

3. Electrical, heating and plumbing safety systems

What to check: service panel condition and capacity, presence of modern circuit protection, exposed knob-and-tube wiring, overloaded or unlabelled circuits, water heater condition and venting, visible plumbing leaks, and corroded supply lines. These systems can create immediate safety or insurance concerns, so prioritise any evidence of unsafe electrical work, rusted gas appliance flues, or active water damage.

Immediate follow-up criteria

Unsafe electrical wiring, open splices, or missing covers require an urgent licensed electrician assessment before closing.
Evidence that past flooding reached mechanical rooms, or corroded water heaters, calls for a plumber or HVAC technician to confirm function and cost to repair.

Questions to ask the inspector on-site

Is the service panel sized for modern loads and properly labelled?
Were any gas venting or combustion air issues observed that could affect safety?
Does visible plumbing show active leaks or systemic corrosion that requires immediate attention?

4. Insulation, ventilation and HVAC performance

What to check: attic insulation depth, signs of air leakage, HVAC equipment age and visible condition, furnace and air-handler venting, heat distribution, and exhaust ventilation in kitchens and bathrooms. Poor insulation and ventilation increase ongoing energy costs and accelerate building deterioration where moisture accumulates.

Infrared thermal imaging is useful to identify insulation gaps, cold bridges at framing members, and hidden moisture that can reduce component life. If HVAC equipment is near the end of its expected service life, request service records or contractor quotes to budget replacement.

Typical red flags and next steps

Insufficient attic insulation or large gaps: plan for upgrade costs and get contractor estimates.
HVAC units near the end of service life: ask for maintenance records and a contractor inspection if heating reliability is a concern.
Poor bathroom or kitchen ventilation: expect higher mould risk and consider repairs to vent ducts or fans.

5. Windows, doors, exterior envelope and drainage

What to check: failed window seals, rot at sills and frames, door alignment problems, deck ledger connections, grading away from the foundation, eavestrough condition, and downspout routing. Water directed toward foundations or failed exterior components commonly result in expensive downstream repairs.

Practical checks you can do during a viewing

Open and close representative windows and exterior doors, note sticking, drafts, or broken hardware.
Inspect grade around the foundation, look for pooling or low spots within two metres of the house.
Check that downspouts discharge at least 1.5 to 2 metres away from the foundation where space allows.

Report expectations

Ask the inspector to prioritise findings by safety, likely cost, and immediacy so you can weigh repair estimates against negotiation strategy. Photographs with annotated locations are essential for comparing contractor quotes.

6. Condos and strata: bylaws, reserve funds and meeting minutes

What to check for a condo purchase: the reserve fund study and current reserve balance, the operating budget, minutes that reference upcoming capital projects or special levies, restrictive bylaws that affect rentals or renovations, and repeated vendor disputes or deferred maintenance noted in minutes. If the reserve fund is small relative to expected repairs or minutes reveal imminent large projects, order a professional condo document review.

A document review examines bylaws, budgets, reserve fund studies, minutes, and insurance documents to identify financial and operational risks that a physical inspection alone cannot reveal. For Alberta buyers, a professional review can highlight likely special assessments or restrictions that affect resale and rental options.

Sample red-flag language

Minutes noting a pending "special levy" vote or an engineer's report recommending large capital work within the next year.
A reserve fund projection that omits expected replacements of major common elements such as roofing or exterior cladding.

If you need a document review, consider ordering it early in your condition period so financial risks are clear before you remove conditions. Spot On Inspections & Reviews offers Alberta-wide condo and strata document review services that translate bylaws and financials into clear action items.

7. How to use the report, optional add-ons and hiring criteria

What to expect from the appointment: attend the inspection when possible, ask the inspector to walk you through the most important safety and structural items, and request a same-day digital report with annotated photos and prioritised recommendations. A clear, photo-rich same-day report is especially valuable when your condition removal deadline is tight.

Time and cost expectations

A typical single-family home inspection can take several hours and results in a written report. Buyers are recommended to attend so the inspector can point out issues in real time.
Optional add-ons such as drone roof inspection or infrared thermal imaging add upfront cost but can prevent missed defects that produce larger expenses later.

How to compare and hire an inspector

Confirm certification to Alberta inspection standards, professional liability insurance, and whether the inspector provides same-day reports and post-inspection Q&A.
Ask for a sample report to judge clarity, photo quality, and whether recommendations are prioritised and actionable.
Check whether the inspector uses drone or thermal imaging when warranted and whether they will refer qualified specialists for suspected major issues.
Compare turnaround times, local experience in Calgary and surrounding communities, and the inspector's availability to meet your condition deadlines.

Sample condition-clause language

Consider wording that makes add-ons conditional and time bound, for example: "Buyer to obtain a pre-purchase home inspection including drone roof inspection and infrared thermal imaging if the inspector deems either necessary. Buyer may require specialist reports, including a structural engineer, and will provide findings to Seller by the condition removal date." This keeps the right to add tests while giving the seller clear timing.

Frequently asked questions

How long does a pre-purchase home inspection usually take and will I get the report the same day?

Inspections for a typical single-family home can take several hours, and most inspectors provide a written report afterward. Many firms, including local providers, deliver same-day digital reports with photos and prioritised recommendations. It is recommended you attend so the inspector can walk you through major findings. For timing reference and the written-report expectation, see the CMLS home buying inspection overview.

When should I add a drone roof inspection or infrared thermal imaging?

Add a drone roof inspection when the roof is steep or unsafe to access, or when a close visual inspection is required and the seller cannot supply a recent roof report. Add infrared thermal imaging when attic stains, inconsistent insulation, or suspected moisture require a non-invasive search for hidden problems. Use these tools selectively when visual checks are insufficient to answer key risk questions.

Do I need a condo document review for a condo purchase in Alberta and what does it cover?

Order a condo document review when the reserve fund appears small, minutes show repeated problems, or bylaws limit your intended use. A document review examines bylaws, budgets, reserve fund studies, minutes, and insurance documents to identify financial and operational risks that affect future costs and use.

What certifications and proof of insurance should I ask for before hiring a Calgary home inspector?

Ask whether the inspector is certified to Alberta inspection standards, carries professional liability insurance, and whether they are insured for drone operations where applicable. Also request a sample report, a clear turnaround promise, and confirmation that optional tools such as drone and thermal imaging are available when needed.

Can a home inspection replace a structural engineer or specialised contractor when a problem is suspected?

No. A home inspector documents and reports visible conditions and indications of possible defects. When the inspector identifies significant structural or mechanical concerns, they will recommend a specialized evaluation by a licensed structural engineer, electrician, plumber, or HVAC contractor for a definitive diagnosis and realistic cost estimate.

Key takeaway: use this seven-point checklist to prioritise safety and budget risk, order drone or thermal imaging when visual checks are insufficient, and insist on a same-day, photo-rich report so you can meet condition-removal deadlines confidently.
