How do I request an inspection?
Call the number on this page. Active water, bowing walls and failed sump pumps get the earliest visits.
How does the contractor find the source?
Walls, cracks, the floor-wall joint, sump pit, grading and downspouts, inside and out.
What does the written quote include?
Options explained side by side, from simple drainage fixes to full systems. Nothing starts until you agree.
How is the work done and guaranteed?
Permits where needed, and workmanship warranties written down.
What should you check before hiring any contractor?
- Ask for proof of insurance and how long they have worked locally
- Ask where they think the water comes from, and why
- Get a written quote that names the system, length and materials
- Ask if the warranty is transferable to a buyer
- For structural work, ask whether an engineer should look first
What else do people ask about the process?
What happens at the inspection?
A contractor finds where the water is coming from and gives a written quote. You decide whether to go ahead.
Who performs the work?
An independent, insured waterproofing contractor that serves your ZIP code. That contractor quotes, performs and warrants the work.
Do I need a structural engineer?
For bowing walls over about 2 inches, horizontal cracks that are growing, or settlement, an engineer's letter is smart and some buyers and lenders ask for one. The contractor will tell you when it applies.
What if my ZIP isn't covered?
We'll tell you. Calls are only routed to contractors that serve your area.
