Listen to Our Customers
"I am so happy with the work your company did in my basement. It looks good and I was thrilled when we were experiencing freezing/rain a few weeks ago. I did not have to bail water like in the past. The water that came in stayed behind the baseboard and went right into the sump pump. The vinyl covering installed over the stone foundation is great as it looks so much cleaner than before and actually adds a little brightness to the basement. I wish I have found you and your company last year. Your workers were very pleasant and eager to answer all questions I had. They left the basement clean every day after their work was done. I will not hesitate if and when I may need to contact you again to have more work done. For now, thank you for making my life less stressful.”

"We purchased our home in Gilford in 2012 and had been told by the prior owners that from time to time some “moisture” accumulated in the crawl space. However, during extensive renovations, various trades working in the crawl space reported quite a bit of water accumulation thee from time to time, especially after a rain storm. We responded to an ad for the Basement Authority (RWN Property Services). They sent a project manager who inspected the crawl space as well as the exterior of the house. He provided an excellent analysis of why we were having water intrusion. He suggested an additional roof gutter and extending the downspouts to carry rain farther away from the house, as well as a large automatic dehumidifier for the crawl space. We agreed with his recommendations and they did the work very competently. Our crawl space is now dry. Very professional job and very reliable.”

"I am with the board of directors for a condominium complex in Bartlett NH. Recently the board was informed of a water seepage issue with one of the complexes units. After consulting with an engineering firm on the best approach to resolving the problem it was determined that it should be dealt with from the outside. This approach proved challenging in trying to find a waterproofing company that would handle a project from the outside . Basement Authority looked at the job and was confident in their expertise in remediating the problem. Company President John Barrett was impressive in his solution based knowledge about product and application of product. He was a pleasure to work with and demonstrated a strong work ethic. If you have a basement water issue I strongly recommend Basement Authority.”
