If you've purchased a new build home in Ontario, you'll go through a step called a Pre-Delivery Inspection — or PDI — before you take possession. It sounds official. It sounds thorough. But most buyers walk out of their PDI having missed dozens of issues that will cost them money to fix later.
Here's what a PDI actually is, what it isn't, and why having a professional inspector beside you can save you thousands.
What Is a PDI?
A Pre-Delivery Inspection is a walkthrough of your new home before closing. It's conducted with a representative from the builder, usually a customer care coordinator or site supervisor. During this walkthrough, you have the opportunity to identify and document any deficiencies — items that are incomplete, damaged, or not built to the standard promised in your agreement of purchase and sale.
In Ontario, the PDI is a formal step in the new home purchase process. Any deficiencies you identify are recorded on a PDI form. The builder is expected to address these items before — or shortly after — you take possession.
What the PDI Is Not
The PDI is not a home inspection. The builder's representative is there to walk you through the home's features — how to operate the thermostat, where the water shut-off valve is, how the garage door opener works. They are not there to point out problems. They are not trained to identify construction deficiencies. And they are certainly not going to hand you a list of their own mistakes.
This is a critical distinction. The PDI is designed to get your signature. That signature is what allows the builder to close the transaction and collect their final payment. Everything about the process is structured to move you toward signing — not to help you find problems.
The reality: Your builder has a financial incentive to get you through the PDI quickly. You have a financial incentive to slow down and document everything. Those two goals are directly opposed.

What Should Be Checked During a PDI?
A thorough PDI goes far beyond checking for scratched countertops and scuffed paint. Here's what a professional inspector examines that most buyers don't think to check:
Exterior grading and drainage. Is the soil graded to direct water away from the foundation? Improper grading is the single most expensive deficiency I find in new builds across Milton, Oakville, and the GTA — and it's invisible to most buyers during a walkthrough.
HVAC system. Is every duct connected? Are dampers installed and functioning? Is the airflow balanced across all floors and rooms? A furnace that turns on doesn't mean your heating system is working correctly.
Plumbing. Do all drains flow properly? Are shut-off valves installed and accessible? Are there any active leaks under sinks or behind toilets? Plumbing issues hidden behind cabinetry can cause thousands in water damage within the first year.
Electrical. Is every outlet properly wired? Are GFCI outlets installed where required? Is the panel correctly labeled? Are smoke and carbon monoxide detectors in the right locations?
Windows and doors. Does every window open, close, lock, and seal? Does every door latch properly? Is weatherstripping installed? Are there scratches, cracks, or broken seals in any glass?
Finish quality. Drywall, paint, trim, caulking, flooring transitions, tile grout, cabinet alignment — these items are individually minor but collectively reveal the overall quality of workmanship in the home.
Why You Need a Professional Inspector
The average buyer catches 5–10 items during their PDI. A professional inspector with construction experience routinely documents 50–100+ items in the same home. That gap represents thousands of dollars in repairs that the builder should be responsible for — but won't be, if you don't catch them before signing.
With 15+ years of construction experience, I know exactly where builders cut corners. I know what fails first in new builds. I know the difference between a cosmetic issue and a structural concern. And I know how to write a deficiency list that gives you maximum leverage with the builder.
When to Book
Book your PDI inspection as soon as you receive your PDI date from the builder. Ideally, give yourself 5–7 days of lead time. I can attend the walkthrough with you, or inspect independently if the builder provides access before the scheduled date.
The important thing is that you have a complete, professional deficiency list in hand before you sign anything.
The Bottom Line
A PDI is not an inspection — it's a sales process dressed up as a quality check. The builder is not going to point out their own mistakes. Municipal inspectors verified code minimums, not workmanship quality. And once you sign off, your leverage to have issues fixed quickly and properly drops dramatically.
For $299, you get a professional set of eyes with construction experience walking every inch of your new home. That's less than the cost of fixing a single plumbing leak — and it can save you thousands.
