Basement Waterproofing in Troy, MI.
Quali-Dry has been Troy's family-owned basement waterproofing contractor since 1992. Our shop is on Piedmont Ave — when you call, the family answers.
Troy's mix of mid-century ranches in the south and 1990s–2000s colonials in the north gives us two distinct basement waterproofing problem sets — and two different fix paths. The south-Troy clay-loam saturates fast every spring, and the wall-floor cold joints on 1960s block foundations are exactly where we focus interior perimeter drainage. We've done the same install thousands of times in this housing stock; the basement is dry through the next storm.
Newer Troy colonials north of South Boulevard almost always have poured-wall foundations with form-tie rod holes that were never properly sealed at original construction. The fix there is rod-hole injection — a $400 visit per hole, not an $18,000 system. We diagnose first, then quote — sometimes the answer is that you don't need a system at all.

How we approach it
Waterproofing in Troy,
done the Quali-Dry way.
Diagnose first. Quote second.
Every wet basement has a cause. We don't carry a one-size-fits-all template. We walk the basement with you, find the actual entry points — cold joint, rod holes, mortar joints, hairline cracks — and recommend only the work that will actually keep it dry.
Interior drainage is almost always the answer.
Exterior excavation runs three times the cost and breaks up your landscape. Inside, we cut a clean channel along the wall-floor joint, lay perforated drain tile in stone, seal it with a paintable concrete cap, and tie it to a battery-backed sump. Same dry basement, a third of the price.
Lifetime, transferable warranty.
Stays with the house, not the homeowner. Sells when you sell. Honored by the same family that signs it. We've kept that promise since 1992 — it's the reason most of our work comes from referrals.

Common questions in Troy
What homeowners
ask us first.
How much does basement waterproofing cost in Southeast Michigan?+
For typical 1,000–1,500 sq ft basements, full interior perimeter drainage with a battery-backed sump runs $7,000–$11,000. Partial systems (one or two walls) are $3,500–$6,000. Crack injections start at $400. We give a written line-item estimate so you can compare it against any other contractor's bid.
How long does the installation take?+
Most full perimeter drainage jobs are 2–3 days from arrival to clean-up, including jack-hammering, drain tile, stone, sump install, and concrete cap. Crack injections are typically same-day. We give a written timeline before we start.
Will my finished basement get destroyed?+
No. Our standard install cuts a 12-inch channel along the wall-floor joint and restores it with a paintable concrete cap. We protect every floor, work around finished walls when possible, and clean up at the end of every day. Plenty of our jobs are in finished basements that stay finished.
Why interior drainage instead of exterior excavation?+
Interior is faster, cheaper, less invasive, and doesn't disturb landscaping or hardscape. It captures water at the actual entry point — the wall-floor cold joint — which is where 90% of leaks originate. Exterior excavation is occasionally the right call for severe structural foundation damage, but it's the exception, not the rule.
