Choosing a Waterproofing Company for Your Washington DC 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.

When you choose a basement contractor in the Basement Systems network, you get a local company trained in and committed to the best waterproofing practices. Each contractor is an expert 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. Say good-bye to your wet basement with the best basement waterproofing in your neighborhood!

Why Do Basements in Washington DC Get Wet?

Flooded basement: Once your basement gets flooded, you want to understand why, in addition to getting it fixed. Severe basement flooding in Washington DC can be caused by heavy spring rains, summer thunderstorms, and flash floods.

Other reasons for wet basements: There are many possible 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.

    The workmen showed up right on time. They were courteous and pleasant – and they told us EXACTLY what they were going to do. Once they dug down to the sewer pipe, Jim was proven correct as the pipe was broken completely in half. Originally, Jim thought the job would take 2-3 days. It was finished in one day – way beyond my expectations. This experience is one of the most satisfying I’ve ever had while having work done on my house. I can’t thank you enough for the courtesy, speed and quality your company provided. The team was fast and accurate. I am forever a customer, and if anyone asks, I will recommend your company as being the best in the business. The experience has been phenomenal, from the first day that Jim showed up to give the estimate right through having all the work done. Kudos to everyone in your company for doing a great job.

    The reason for this high review is because of the high quality character of Jim. NV came to my home to investigate water infiltrating my basement from a front foundation wall. Jim assessed the problem as best he could, but because I had left the dry wall up he was unable to immediately access the area inside the drywall. Being at work at the time, I asked my wife to cut back some of the drywall to take a better look. Jim stayed and not only helped my wife cut away the drywall and remove sopping wet insulation, but helped her find that the problem had originated with a leaking pipe in the wall that we did not know was there. Although the company policy against removing the drywall themselves seemed odd to me, nevertheless it was their policy. Jim went above and beyond to help my wife remove the drywall and insulation, which with two small kids was going to be very difficult for her to do by herself. He helped clean up and was polite and respectful. While I am grateful I do not have a foundation leak, should I ever have one, I will call NV Waterproofing and ask for Jim. Quality people are hard to find, thanks man.

    We used NV Waterproofing (NV) to fix a basement water leak in an addition to our house. NV provided the clearest estimate (we received estimates from multiple companies), with clear pricing and identification of issues. NV completed the work promptly. While the initial work did fix the primary problem, we had a small leak remain. NV was great about coming back out to figure the issue out, and found a surprising construction anomaly causing the second small leak. NV fixed the problem (all as part of the initial estimate) and our basement has been dry since. We were very pleased with NV's persistence and ultimate solution to our problems. We strongly recommend NV.

    We have used NV Waterproofing several times now for different issues that have arisen in our basement. We have found them to be very professional, courteous, and knowledgeable. Unlike many other waterproofing companies which try to sell you very expensive one-size-fits-all whole-house solutions (which are a rip-off with no guarantees), NV Waterproofing takes the time to target your specific problem and provides the most economical and effective approach to the problem. We appreciated their honesty and creativity in designing a plan for our flooding issues. So far, all of their work has held up great! I would highly recommend them.

    I wanted to take a moment to thank you and NV Waterproofing for a job well done. From your visit to our home, to the reasonable estimate, to my communications with Jayne, working with NV Waterproofing has been an excellent experience. The work crew showed up on time, finished in one day and left the basement very clean. My wife commented on how friendly the crew was, and they answered all of her questions. We look forward to rainy days now, without the fear of our basement leaking. Thanks again to all!

    Mauricio explained 3 options that would fix the water problem we were having in our basement. He gave me details about the materials and process NV watering proofing would be using in my home. He never tried to sale me something I didn’t really need. Rich arrived on time. He walked me through what he was doing. He put everything back so well, you can’t tell any work was done on that wall. I would definitely recommend this company and their crews!
