Every Markham home has a different flood risk profile: the age of the foundation, how the weeping tile drains, whether there's a sump pump, the condition of the sewer lateral, the grading around the house. A flood protection assessment looks at all of it together and gives you a clear, prioritized plan — instead of guessing which upgrade matters most.
The assessment covers the three ways water gets into a basement: back through the sewer, up through the ground, and in through walls and windows. You get a plain-language report of your home's weak points and the measures that address them, in priority order. The City of Markham's Private Plumbing Protection Rebate Program can help offset the cost of this work. Two things matter most: you must get pre-approval from the City's Environmental Services department before any work begins, and the work requires a permit and a City inspection. Rebate amounts change, so confirm current amounts with the City before you plan your budget.
Flood Protection Assessment Around Markham
Flood risk in Markham is hyperlocal. Two houses on the same street can have completely different exposure depending on grading, foundation age, whether weeping tile connects to the sanitary sewer and what's been renovated. An assessment replaces assumptions with a camera, tests and a prioritized plan.
For buyers, an assessment before closing is one of the few ways to see a home's real flood risk — standard home inspections don't test sump pumps or camera sewers. For owners, it's the fastest route to a rebate application grounded in what your home actually needs, with the pre-approval sequence handled in the right order.
Signs You Need Flood Protection Assessment
An assessment is worth booking if:
- You've had water in the basement. Once is enough. Understanding exactly how water got in is the only way to make sure it doesn't happen again.
- You're finishing or renovating the basement. The time to fix flood risk is before the drywall and flooring go in, not after they're damaged.
- Your home is older and has no flood protection. No sump pump, no backwater valve and original drainage means your protection is entirely passive — grading and luck.
- Neighbours have flooded. Flood risk is shared across streets and subdivisions. Nearby flooding is a preview of your conditions.
- You're buying a home in Markham. An assessment before closing tells you what protection the home has, what it lacks and what the gaps would cost to close.
- Your insurer is asking questions. Sewer backup coverage increasingly comes with questions about protection measures. An assessment gives you documented answers.
How We Do It
- 1
Review the home's history
We start with what you know: past water entry, the home's age, previous plumbing work and any existing protection.
- 2
Inspect the drainage systems
Sump pit and pump, floor drains, backwater valve, cleanouts and the visible drain system are all checked and tested.
- 3
Camera the sewer lateral
Where indicated, a camera inspection shows the condition of your sewer line and how your foundation drainage connects.
- 4
Assess exterior factors
Grading, downspouts, window wells and foundation condition all contribute to risk and are part of the picture.
- 5
Deliver a prioritized plan
You get a clear report: what's protecting you now, what's missing, and the measures that matter most — in order, with honest pricing.
- 6
Explain the rebate program
For qualifying work, we walk you through the City's rebate process, including the pre-approval requirement that must happen before work begins.

Flood Protection Assessment FAQs
What does a flood protection assessment include?
A review of your home's history, inspection and testing of existing protection (sump pump, backwater valve, drains), a camera inspection of the sewer lateral where indicated, an exterior review of grading and downspouts, and a written, prioritized plan with pricing.
Can the assessment help me get the City rebate?
Yes — it identifies which qualifying measures your home needs, so your rebate application is based on a real plan. Remember that pre-approval from Environmental Services is required before any work begins, and the work requires a permit and City inspection. Confirm current amounts with the City.
I'm buying a home. Should I get an assessment before closing?
If the home has a basement and is more than a couple of decades old, it's one of the smartest pre-purchase checks available. Standard home inspections don't test sump systems or camera the sewer.
How long does an assessment take?
Typically one to two hours on site, depending on the home's size and whether a camera inspection is included. The written plan follows promptly.
If the assessment finds problems, do I have to use you for the work?
No. The assessment and its report are yours. Most clients do ask us to do the work because the plan and pricing are already clear, but there's no obligation.
