About Philadelphia Waterproofing Companies

If you go down to your basement and the air feels damp or smells musty and moldy, chances are your home is in need of waterproofing. Dealing with a water problem sooner rather than later is essential because water is one of the worst enemies of a home. When left untreated, moisture problems can be persistent, expensive, and particularly frustrating if your basement is (or was) a functional living space. Worst of all, a longstanding moisture problem could create a haven for mold, which can have very real health repercussions for you and your family. In the event your home has a crawl space instead of a basement, these issues are still a concern—any crawl space that isn’t sealed off and properly conditioned can develop the same moisture damage and mold growth as a wet basement.

Few homeowners are able to resolve moisture problems on their own; the cause of the issue can be hard to pinpoint and even harder to remedy with your average toolkit. Just painting over water spots, for example, is not a solution. Instead, you’ll need to enlist the help of a waterproofing professional who has likely seen it all and knows what works and what doesn’t when it comes to water problems. Picking the right company for the job can be difficult, and that’s why EBSCO Research has taken the guesswork out of finding a Philadelphia waterproofer—we contacted thousands of local homeowners to find out who did the best work for them on their homes. With an overall A grade from their customers, along with proper licenses and insurance, the Philly waterproofing companies on our list have earned the title EBSCO Research Best Pick™.

If you are experiencing moisture problems in your home’s basement, the first step a waterproofer will take is to identify exactly what’s causing the water intrusion and then determine the best way to treat both the cause and symptoms. Remedies come in a variety of forms and depend on both the nature of the problem and the kind of foundation you have. Sometimes the best solution is to install a drainage system that channels water away from the structure, while in other cases sealants are injected into foundation cracks in order to seal out a leak. Philly Best Pick™ waterproofers can also install many other moisture-control solutions, such as waterproof membranes and dehumidifiers.

If you have a crawl space prone to moisture problems, a Best Pick™ waterproofing company will have expertise in crawl space encapsulation services as well. The encapsulation process comprises multiple steps, from installing a waterproofing system and a vapor barrier to adding insulation. The multiphase work is worth it—a sealed and conditioned crawl space can result in lower energy bills, in addition to protecting your home from damage due to unchecked moisture.

EBSCO Research talked to thousands of Philly residents just like you to find the best home service providers in your area. Companies carrying the Best Pick™ ribbon have passed a rigorous test of quality, scoring an A grade from at least 100 of their customers. Additionally, EBSCO Research has independently verified that each company possesses the requisite licensing and insurance coverage. When you hire a Best Pick™ Philadelphia waterproofing company, you can be confident that you’re using the best there is. All you have to do is look forward to resolving your water problem effectively and efficiently.
