Home / Services / Basement Waterproofing / Royal Oak, MI
Royal Oak basements are some of the trickiest in Southeast Michigan — small lots, old block foundations, and original 1920s tile drainage that's mostly clogged. We fix them right.
Royal Oak's 1920s–1940s bungalows on small lots are some of the trickiest basement waterproofing jobs in our service area. Downspouts dump too close to the foundation, original tile drainage from the 30s is mostly clogged after 90 years, and most homeowners are protecting a finished basement that needs to stay finished during the install.
We work them carefully. Interior perimeter drainage with bleeder holes drilled through the original block, tied to a sealed sump with battery backup, restored with a paintable concrete cap. A typical Royal Oak job runs $8,500–$12,000 over two to three days in 48067 or 48073. Lifetime transferable warranty, signed in plain English.

How we approach it
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.
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.
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.
What's included
Common questions in Royal Oak
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.
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.
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.
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.
