"I was reassured when a home insurance adjustor who saw the quality of work by the waterproofing team of Jaime and Jose said it was excellent. They provided very professional customer service. They were patient and thorough in answering my questions and instructing me on how to maintain the new sump pump they installed. I would recommend that anyone considering this services specifically request the team of Jaime and Jose."

"They wanted to inject very expensive sealant into the ducts to seal the seams. The company I hired used insulating tape over the seams instead, for a greatly reduced price. The total price difference in their proposal and the company that I hired was about $4500."

"JDS is a fantastic company and a pleasure to work with. Jordan, the owner, came to my house to evaluate the job and provide an estimate. He was very detailed and honest in his assessment. He made various recommendations that substantially improved the setup of the systems, including some that helped reduce costs. A few days before the job was to start, I had to re-schedule due to unrelated reasons. Jordan was able to reshuffle his schedule to be able to accommodate my new timeframe. His crew was always punctual, clean, and respectful of my house. They worked very efficiently and were able to complete the job in under a week. The two windows look great and have substantially improved the feeling of the basement, I would highly recommend JDS to anyone looking into egress windows. Outstanding experience!"
