About Washington, DC Waterproofing Companies

Unaddressed water problems can cause a range of dangers and frustrations for the unlucky homeowner. If ignored, moisture issues in the basement or crawl space can result in dramatically reduced indoor air quality, a compromised foundation, and mold growth.

What’s more, a problem may go undetected for months or even years, and the longer the issue is ignored, the more costly the problem is likely to become. For that reason, homeowners who notice a water problem should contact a waterproofing professional right away.

Wet Basement Signs, Causes, and Solutions

Aside from obvious dampness or water in the basement, other signs of a water problem include musty odors, cracks in the foundation, and a white, powdery residue called “efflorescence” visible on the walls and foundation. These signs are harder to detect in finished basements, where homeowners should look for peeling or puckering paint/wallpaper, water stains, and swollen baseboards.

While the most common culprits for water problems are poor grading, improperly functioning gutters or downspouts, and a high groundwater table around the house, many DC-area homeowners’ moisture problems are simply the result of old construction.

Water is extremely corrosive to building materials, and over time, even high-quality waterproofing systems can degrade and eventually become ineffective. Because DC claims some of the oldest residences in the country, with the largest share of DC homes having been built during the 1920s, basement water issues and unstable foundations are a common problem among homeowners.

If you are concerned about water problems—and especially if you live in an older home—contact a waterproofing specialist to inspect your system, and plan for periodic inspections in the future. If this is neglected, you may notice a moisture problem beginning to develop.

Basement waterproofing methods

As for wet basement solutions, unfortunately there is no one-size-fits-all approach. There are many waterproofing methods, including exterior excavation for more advanced problems, interior drainage systems, and sealant waterproofing, and still more factors that contribute to the seriousness of a basement water problem.

Depending on the source of the water and the extent of the damage, a quality waterproofing or foundation expert will be able to determine the best waterproofing solution on inspecting your home.
