Choosing the Right Waterproofing Company for Your Delaware Basement

Wet basements are not fun! Flooded basements are a homeowner’s nightmare. If you are suffering from constant worry about the health and safety of your basement, it’s time for a change. If you’ve tried DIY efforts to fix pooling water, cracks in your foundation, leaky basement windows, or high humidity, it’s time to find an experienced, professional waterproofer you can trust. A wet basement wastes valuable living space, damages building materials and stored possessions, pollutes the indoor air, risks the health of those living in the home, and puts your investment in your home at risk. That adds up to considerable risk.

Look for expertise, training, and experience

By choosing a basement waterproofer in the Basement Systems network, you’re getting a local company dedicated to the best waterproofing practices. Each contractor listed here is a trained professional in the diagnosis of sub-grade moisture problems as well as the design and installation of proper drainage, moisture and humidity control, and basement materials. All Basement Systems contractors are licenced and certified to fix your damp basement. With this kind of expert assistance, you can say good-bye to your basement water issues!

Why Do Delaware Basements & Crawl Spaces Get Wet?

Flooded basement: Delaware has an annual precipitation that averages about 55 inches statewide. That along with low land near the coast can lead to serious flooding issues. When flooding hits your area, your basement is most likely to be the prime target for water damage.

Other wet basement signs: There are many potential sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.

    Mark S. of Long Neck, DE

    Customer Testimonial

              I was so thrilled with the work that DryZone completed for me. Ususally you find contractors who leave trash and you had to clean up after the crew. Mario and his team were so respectful and such great workers. I have worked in contracting, plumbing, and electrical for years. I have been around lots of contractors and never have I met a crew of people so good at their job. I was so thrilled at the results of my crawl space and so impressed by the DryZone Crew! It felt like they cared about my home like it was their home. It was so refreshing!

    Kathi T. of Dover, DE

    Customer Testimonial

              Kathi T. from Dover, Delaware was extremely upset with her home's chronically wet basement. While she had lived with the problem for a number of years, she had reached a point where she could no longer stand it. Her son had just moved back in and was living downstairs when melting snow from a recent storm put her entire basement under four inches of water, which poured in from virtually every corner. She called a few companies from out of state and didn't really like the experience she had with them. Not only the solutions they were proposing didn't make much sense to her, but the sales people were extremely pushy, and used every gimmick in the book to try to pressure her into signing a contract with them. Being a Marketing teacher, she was very familiar with this type of high pressure sales tactics, and was not only unimpressed, but frustrated as well. She then decided to call a local company, and searching the internet, she found DryZone LLC. Her experience with the company was entirely different, and in this video she speaks about it from the sales process, to the installation which was done quickly on the verge of a huge snow storm, predicted to cause accumulations of up to 22 inches of snow in Delaware. They assured her the work would be done before the storm and they did it. "When people got here to do the install I was so upset about the weather forecast. They were like ''Ma'm, we're gonna get this done if we have to stay here until midnight' and they literally pulled out of the driveway, I believe it was on the third day, as it was starting to snow", explains Kathi"I would recommend DryZone to anybody who like me value their property, their home", she concludes.
