Thompson Brothers offers waterproofing services for basements and crawl spaces in new construction and residential homes, or commercial buildings. Waterproofing your basement and crawl space ensures that standing water and high moisture do not cause structural damage, mold, or other water issues. Our waterproofing experts can also inspect your basement and crawl spaces to determine the moisture level, and recommend solutions to keep moisture in your basement or crawl space at an acceptable level.

Basement Waterproofing

We offer exterior basement waterproofing (along outside walls) and interior basement waterproofing (along inside walls). We waterproof basements based on construction type and needs, to prepare new construction, fix leaky basements, or seal basement walls against future leaks or flooding.

Foundation Waterproofing

Every home is built on some form of foundation, whether yours contains a crawlspace or basement. Let our team of foundation waterproofing experts inspect and make recommendations for your home to protect your foundation from water damage, mold, and pests that thrive in moisture.

New Construction Waterproofing

For new construction homes, our team uses Rub-R-Wall, a waterproofing system that is asphalt-free, non-toxic, and non-carcinogenic. Rub-R-Wall has been recommended worldwide by architects and builders. It is effective for use on block and poured concrete walls and comes with a lifetime warranty.

Crawl Space encapsulation

High moisture levels and standing water can cause unwanted damage in or around a structure. We offer these crawl space waterproofing solutions that can be paired together or used alone to help bring moisture back to acceptable levels, based on your specific needs:

  • Dehumidifier Systems 
  • Moisture Barriers 
  • Crawl Space Drain Systems

Sump Pumps

A sump pump removes water from the lowest point of your home (like a crawlspace or basement) and relocates it outside to prevent flooding or water damage. Our team has several years of expertise in sump pump installation for your home.

Retaining Walls

Thompson Brothers designs and builds segmental retaining walls to fit the contractor or homeowner's needs. Retaining walls protect your home’s foundation by preventing erosion, managing water flow, and blocking water damage. With more than 15 years of experience, we can build the right system for any type of home or construction project.

Water Damage restoration services

Prolonged moisture and water in your home can cause damage to your floors, subfloors, joists, and seals which can lead to pests, mold, and other issues. Our trusted team has expertise in water damage repair services to remediate the root of the problem.

What Our Customers Say

Sharon P, Waterproofing & Repair

We had extensive water intrusion that our inspector did not see. Thompson Brothers had to engage in grading, extensive digging, reinstallation of French drains, and install a new drainage field. The work was excellent. All personnel is polite, on time, and very professional. Highly recommend.
