Who publishes this and how the numbers are made
We research prices and pass each enquiry to one independent local company. We do not waterproof basements and have no stake in which method you choose - which is exactly why we can tell you the cheaper one is often correct.
This is an independent price research site. We collect quotes city by city, publish the ranges, and explain what moves them.
How we make money, stated plainly
When you send an enquiry we pass it to exactly 1 independent local company anywhere in the United States, and they pay us a flat monthly fee for the introductions. Your details go to that one company - never shared with several, never sold to a lead broker. That is the reason you get one phone call instead of five.
What we do not know
- Where your water actually enters, which only an on-site look settles
- Your excavation depth, which is most of the exterior price
- Whether your problem is a $300 downspout or a $14,000 system
We have researched prices in 3 United States metro areas for this trade so far and add cities as we collect enough quotes to publish a defensible range. Published ranges are researched, not quoted.
Across the United States we have found quote spreads of 2x or more on identical scopes, which is the single strongest argument for getting more than 1 written quote before signing anything.

If the answer is on the site we will point you at it. If it needs a person, we pass it to one local company.
