DSI, Inc. was hired for a structural wall repair project due to water intrusion. While in the process of planning the restoration, a waterproofing product, Hydro Stop Barrier Guard, was suggested and agreed to in order to protect the repaired wall. To complete the job, french drains were installed as the final piece to the solution. The job took five days and was a great value considering the labor involved, the high quality of materials chosen, and the expert planning done by David Spence,owner. The final cost deviated only slightly from the original estimation due to a structural concern uncovered after digging. The owner, David Spence, visited the site often. Kristy, office staff, responded promptly to my questions and the crew in the field, Butch and Marshall, were knowledgeable , punctual, neat, and respectful of my property. To my surprise, the Hydro Stop Barrier Guard representative, George ,from Quest Construction Products, even joined the DSI crew for two days to work on waterproofing the walls with his product. As a customer I was impressed by the positive working relationship between manufacturing and construction. I credit that to David Spence's business policy of integrity and reliability. It was truly a pleasure doing business with such a professional firm who knows how to get the job done correctly and who has commendable customer communication skills.
