Halo Water Proofing has been the trusted call for Sump Pump Installation across Markham because we answer the phone, show up when we say, and stand behind the work.
Background-checked Markham technicians · 24/7 dispatch
Halo Water Proofing is a VA-licensed Sump Pump Installation company that treats every Markham job like it's the only one on the schedule.
We don't run a bidding war between crews. The Markham technician who inspects your property is the same one who does the repair, start to finish.
Our Markham crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Markham calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Markham homeowners notice, well before any water is visible.
Small cracks in a Markham foundation rarely stay small — seasonal ground movement tends to widen them over time.
Efflorescence is a reliable early sign that water is moving through your Markham foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Peeling paint near the floor upstairs is one of the last signs Markham homeowners connect to a basement problem.
No two Markham basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Markham basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →Most Markham pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →Older Markham homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Markham jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
A real technician asks the right questions to understand what's likely happening at your Markham property before anyone drives out.

Every Markham quote is written before work starts, not estimated verbally and adjusted later.
You get documentation of the work plus a real warranty — not just a handshake.
