Free Waterproofing and Repair Quotes

At Clarke Basement Systems, we offer free, no-obligation waterproofing quotes to homeowners within our service area.

During your Free Estimate, our waterproofing specialist can answer any questions you may have about your wet basement or crawl space.

Our free quotes include all of the following:

Our 88-Page Waterproofing Book: Before we meet with you, we'll send along a copy of one of our 88-page crawl space and basement waterproofing books.

This book features our full selection of products, while explaining why basements leak -- and what we can do to permanently solve your problem.

A Personal, On-Site Inspection: Your waterproofing or foundation specialist will inspect your basement or crawl space to identify sources of flooding and moisture and explain the problem in depth.

Your Complete Waterproofing System Design: Our waterproofing specialist will measure your basement's dimensions and identify the best spot to place the sump pump and run your discharge line. You select which of our products you'd like in your home, and we make a plan together.

Our FREE Written Quote: We provide our customers with a free, no-obligation written quote at the end of each visit. Our prices are firm -- there will be no hidden expenses later on, and there will be no high-pressure sales techniques.

We Solve All Your Basement, Crawl Space, and Foundation Problems

We'd like to show you how we can help you waterproof your basement, control moisture in your crawl space, or fix a failing foundation. We have the experience, equipment, and best practices you need to ensure a dry basement and structural integrity.
