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!

Carlos L., Arlington, VA

I contacted NV Waterproofing to fix a minor crack in my basement wall. The stress and anxiety were greatly alleviated because of the outstanding professionalism shown by your employee. He took the time to explain the procedures he would use to fix the crack, step by step. He also showed me the progress he was making throughout the procedure. He left my yard very neat and clean after the work had been done. He dug a very deep hole with extreme precision. Due to the professionalism, politeness and diligence shown by your crew, I would highly recommend your company to any of my friends and business associates.

John O., Alexandria, VA

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!

Peter V., Falls Church, VA

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.

Ramesh T., Arlington, VA

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.

Fred L., Sterling, VA

Your crew worked hard all day, only taking a short time for a quick lunch. The men were neat, completely covering all areas that they used to remove concrete, dirt and debris. They were on task the entire time. We were very impressed. We have had a lot of work completed in our home over the last 38 years, and I am pleased to say that your employees are the most conscientious we have ever worked with.

Mat and Peggy M., Ashburn, VA

Thanks for doing the job so promptly. Your crew chief was excellent – very nice and professional.

Janet and Butch N., McLean, VA

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.

Mike and Lynn F., Columbia, MD

We are extremely pleased with the outcome of the project and the high caliber of work performed by the crew.

Daliah L., Stafford, VA

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.

Myra L., Washington, D.C.

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.

Darryl O., Brookfield Homes

NV Waterproofing was called to a difficult and challenging waterproofing site, and they were able to meet the challenge with confidence and experience. The problems were resolved as were other issues found during job. They were respectful, responsive and thorough. They went beyond just waterproofing.
