Sagging Crawl Space Joist Repair in Greater Washington D.C.

NV Waterproofing was extremely responsive and 100% committed to identifying our water problem and designing a solution. Their work was excellent. The crew was on time and organized. They were very careful to protect the exterior landscaping and the interior of our home from dirt and debris. Even two years later, they responded to a sump problem at no additional charge. NV Waterproofing does the job right and stands behind its work.

We bought a house in a state of disrepair, and so we've had to work with a number of contractors. I'd rank this company at the top of the list for their professionalism, knowledge, experience, and honesty. We had bowing of our basement walls that needed to be addressed. Michael came out to assess the situation, and gave us some options. After speaking with him, I felt very confident in their ability to buttress our walls. It was also a huge bonus that we were able to set up a payment plan for this job too. When the team showed up, Casey, Kevin, and Grant, they were super polite and professional. They took great care of our property, and if they had a question about anything, they asked. Also, if I had a question, Casey (the foreman), was very knowledgeable and quick to answer. They presented the work as they progressed through the job, and really, I was actually a little blown away by the scale of the project, and the speed at which they worked. What an impressive job they did! We're very confident in the work they did and will hire them again.

We were referred to NV Waterproofing from my brother-in-law who used them and was pleased. They came out and gave us an estimate - they were very prompt. We had the work done - it looked great and I am sure will do the job (only time will tell). We did have a miscommunication with the work (mostly on our part), but the owner had it fixed promptly and without additional cost. I would highly recommend them to anyone with water issues in their basement.

NV stuck with me and made sure I was happy. Roberto Jr kept me calm as my problem persisted and kept working on a solution beyond the obvious. I highly recommend. Looking forward to a dry basement this summer.

I am writing this letter to commend members of your organization for the waterproofing work performed on and around the foundation of my house. Despite situations beyond the control of both me and your associate, he always maintained professionalism and demonstrated why he is an outstanding representative of your organization. The crew obviously knew what had to be done and went about doing it. They were prompt in arriving at work each day, diligent in the performance of their duties (in spite of high heat and humidity), and took measures to ensure the safety around the excavated area (important because of children in the neighborhood). Unlike other construction sites I have seen, the crew maintained the area free of litter— no small measure these days! In addition, the crew always provided clear explanations of the work to be done each day, answering the questions with forthright and clear responses, never hurrying the discussion. As I was not on site while work was being done, they called me several times, taking those extra steps to keep me informed of the status of the work and aware of the tasks yet to be performed— something that is greatly appreciated. I would appreciate it if you would offer my heartfelt thanks to your able crew for the quality waterproofing work performed and the excellent communication and coordination exhibited by them.

In my 12 years of having NV Waterproofing as a business partner, they have always proved reliable and trustworthy. They are a great value for me and my customers.

Great professional service and able to respond in timely manner to the project need.

Brendan was very knowledgeable, professional and courteous. Highly recommend.

A brief note to thank NV Waterproofing for extreme professionalism and courtesy in the manner in which my recent basement water seepage problem was addressed. From the initial contact with Jim, through the work with Roberto, Carlos and Jose, it was an overall pleasant experience – not to mention my contact with the owner and his responsiveness.

These guys were amazing. The initial visit was smooth, not pushy at all and he was even able to accommodate the relocation of a small drainage pipe. The demo to install the system was done beautifully, yes it was really good, you can tell they were precise and careful when doing so. Everything was clean, no stains on my carpet and they protected everything. No leak so far and I love it. Did I mention the price was excellent? I had 3 other companies to estimate thousands and even tried to sell extra unnecessary equipment. Thank you NV Waterproofing I have and will continue to recommend you.

We appreciated NV Waterproofing's honesty and the men who worked tirelessly in uncomfortably cold weather. We've had one big storm since they finished and the basement walls are nice and dry. Nice work!

Mauricio and Cristian were the initial sales reps who came to examine the issue and they took the time to test drainage that might have potentially been creating the water issue. They offered a reasonable solution (sealing the visible cracks and holes in the concrete) and I was contacted within a couple of days with an estimate and scheduling options. Sean was our tech and he did a fantastic job diagnosing the issue beyond just the cracks. He not only address all the holes and cracks in the concrete and mortar, he sealed up additional entry points above the foundation. He sourced additional materials to cover openings for cable lines. He went above and beyond and gave us measured information on how we should continue to monitor and treat this area as the house settles. He was thorough, informative, and provided excellent service in his work. I'm very glad that Sean was the technician sent to us and I would specifically request him for your projects.
