The Ranking

Our top 9 waterproofing contractors in Houston

Most Houston homes sit on flat clay that swells when wet and shrinks when dry, so waterproofing here is mostly about moving water away from the slab, not sealing a basement. That means French drains, channel drains, regrading, sump pumps for low yards, crawl space moisture control under pier and beam homes, and sealing the exterior shell. Many of the companies below are foundation repair firms that also install drainage, and each profile says where drainage sits in its work. Texas has no state waterproofing licence. Plumbing work such as sump pump discharge and drain lines falls under the Texas State Board of Plumbing Examiners at tsbpe.texas.gov, and the City of Houston requires permits for some drainage and plumbing jobs. Ask for proof of insurance, a written scope and the warranty terms before you sign, and check whether the person quoting also runs the crew.

Methodology

How we chose the best waterproofing contractors in Houston

This list follows Google Maps order for Houston drainage, foundation and waterproofing searches, read October 21, 2026. Each company has a 4.5 star rating or higher, at least 50 Google reviews, an operating status, a working website and a staffed Houston street address, and none paid to be listed. Houston has few pure waterproofing specialists, so several entries are foundation or exterior specialists that sell drainage or sealing, and each profile discloses that focus. Companies that did not sell drainage or waterproofing, used template or multi-city doorway sites, or listed suite or residential addresses we could not confirm were removed and the next closest firm was checked instead. Nine firms passed, so the list is shorter than ten.

Hiring

How to choose a waterproofing contractor in Houston

  1. Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  2. Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  3. Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  4. Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  5. Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  6. Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  7. Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  8. Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

FAQ

Waterproofing companies in Houston FAQs

Do Houston waterproofing contractors need a licence in Texas?

No, Texas has no state waterproofing licence. Drain lines and sump pump discharge that tie into plumbing fall under the Texas State Board of Plumbing Examiners at tsbpe.texas.gov, and the City of Houston issues permits for some drainage work. Ask any contractor for proof of insurance, a written scope and warranty terms, and check a plumber's licence on the state lookup.

How much does yard drainage or waterproofing cost in Houston?

Cost depends on lot size, drain length and whether a sump pump is needed, so get at least two written quotes. Most companies here offer free inspections or estimates, and one, Duratech, publishes price ranges for regrading, gutters and root barriers. Ask what the warranty covers and whether yearly maintenance is included, since pumps and drain outlets need checking after heavy rain.

Why are most Houston waterproofing companies foundation repair firms?

Houston homes sit on slabs and pier and beam foundations over expansive clay, so basements are rare and water control means drainage around the foundation. Many foundation firms sell French drains, grading and crawl space moisture control for that reason. Each profile here says how central drainage is to the company's work, so you can pick a drainage specialist or a foundation firm that adds drains.
