Top Waterproofing Companies

Waterproofing contractors stop water from getting into a structure. Below grade they apply membranes to foundation walls, install drainage boards, interior drains and sump systems, and inject cracks; above grade they seal flat roofs, balconies, plaza decks, parking garages and wet rooms with liquid-applied, sheet or polyurethane systems. Property owners and builders call them after leaks, mold or efflorescence appear, during new construction, or before converting a basement into usable space.

Some firms listed here also do roofing and masonry, while others only waterproof. Ask which manufacturer systems each is certified to install, and compare reviews on projects with the same type of substrate and exposure as yours.

Buyer's guide

Hiring Waterproofing Services companies

What the work covers, how to judge a partner and what drives the price.

What waterproofing companies install and repair

Work starts with leak diagnosis: moisture readings, water testing, and a look at grading, gutters and drainage to find where water actually enters. The contractor then specifies a system. Positive-side membranes go on the exterior of foundation walls during excavation; negative-side treatments, crystalline coatings and interior drainage handle walls that cannot be dug out. Above grade, contractors install liquid or torch-applied membranes, traffic coatings for garages and balconies, and sealants at joints and penetrations.

Commercial jobs may include a flood test before tile or pavers go down, and many manufacturer systems come with a warranty only when installed by a certified applicator and inspected. Residential portfolio owners often buy annual inspections and joint resealing as a maintenance contract.

Waterproofing Services FAQs

Short answers to what buyers ask before hiring a Waterproofing Services company.

Question not covered? Ask our team

A waterproofing company finds where water enters a building and installs systems to stop it, including foundation membranes, interior drains and sumps, crack injection, and coatings for roofs, balconies and garages. Many also offer inspection and maintenance contracts.

Waterproofing is priced by area or as a lump sum, and cost rises with excavation, access, substrate condition and the system used. On Edverise, many contractors take repairs with no minimum or from $1,000, while large commercial specialists set minimums of $100,000.

Damp proofing is a thin coating that resists moisture vapor and light soil dampness but cannot handle water under pressure. Waterproofing uses membranes and drainage designed to keep out liquid water, including groundwater under hydrostatic pressure, and is required where water tables are high.

Choose a contractor that diagnoses the source of the leak before quoting, names a specific manufacturer system it is certified to install, and offers a written warranty. Check licensing, insurance and references for the same type of structure, such as basements or plaza decks.

Real estate owners and property managers are the most common clients of the waterproofing contractors listed here, followed by business services firms, manufacturers with plants and warehouses, utilities, and consumer businesses with retail or storage space.

Waterproofing companies on Edverise are listed in places including New York, Brooklyn, The Bronx, Iowa City and Bucharest. Since crews must be on site and often licensed locally, choose a contractor that regularly works in your area.
