    Customer Testimonial

              Hello and thanks for providing such a quality system and for caring about your customers long after the system installation. Your service tech Arron, just finished the service visit at our house. He did a great job, was professional, courteous and knowledgable. Every company out there should hope that their own people should do such a great job. In this day and age all too often companies forget about the consumer after they cash your check. Great job to all your staff.

    Customer Testimonial

              My husband and I wanted to write and let you know how impressed we were with the crew that came out. I do not know all of their names, but Francisco Mendoza appeared to be the leader. The three gentleman were extremely courteous, professional, trustworthy and hard-working. The first day, I never saw them even take a lunch. They worked solid. But what impressed us even more was the fact that they were laughing, joking with one another , and singing. Are the while they were working very hard and in difficult circumstances. It is not pleasant in the crawl space under an home. There just is no room. They even apologized to me for the noise when they were going to be making loud noises under my home, whiled was working inside. When they finished each day, they cleaned up everything. They hauled every bit of garbage away.my husband was impressed because on the first day, they even cleaned up the mud on the driveway. The second day, I told them not to do it, because it was getting so late in the day. But I know that they would have still done it. The second day was a repeat of the first. It was raining and not exactly comfortable weather but they still maintained their sense of humor. I could tell they were tired. So I made them sandwiches which they thanked me profusely for. But I never saw then take a break to even eat them, ever though I know they did. Any questions I asked, they answered promptly and expertly. They even told me things that we could do to improve our crawlspace. They made me feel so comfortable, that I even left my home to run some errands while they were there, with my front door wide open. when they were nearing the end, they showed me how everything worked and then graciously repeated everything for my husband a few minutes later when he came home from work. This fantastic crew was the best advertisement of what your company values are and I'm glad we did not cancel. I was so excited to see the water gushing into the street.

    Customer Testimonial

              days have made! Even after all the rain we've had on Tues and Wed, not to mention the wind and rain storm yesterday, my basement is completely dry. Of course, I did have hope the waterguard system would work, but somehow it seemed almost too good to be true. Not so. It does seem to be true. The crew was terrific. They covered all my stuff with plastic and cleaned up thoroughly when they finished. The jackhammering seemed to take only a few hours on Monday and the gravel and half the system were laid. I can't believe how fast it went. On Tues the exterior drainage lines were done--in the pouring rain--and the sump pump installed. The cement over the interior trenches was neatly done and you would never know it's there. The same with the exterior which wa snot at all an easy job. I can't say enough about the professionalism of the salesman Kenny Low and of the crew. Lorenzo, Delfino and Corey. I want to recognize each man and thank them all of the their hard work. I still find myself going downstairs to see if there is water coming through the center of the floor. and the shop vac is still sitting nearby but nothing has come. What a sense of relief. Thank you!

    Our inspector Eric went out and found the water had been leaking from the basement window. Water was coming from outside to the window and leaking down the wall to the basement floor. We installed our patented WaterGuard system along the perimeter of the basement floor. To fix the window leaking we installed a window well drain that goes under the window and drains the water to the unseen WaterGuard system. To which drains the water to the Super sump that pumps the water out and away from the house.

    This homeowner had a beautiful finished basement but this last year the wall was softening and has a strange dark area. When our team came out to inspect they discovered that this was due to a large concentration of wet soil behind the basement wall on the exterior. Over time water began to work its way through the concrete wall and now the family risked damage to the finished walls of their home. Our team came in and placed not only a drain system to collect this water but also installed our patented Bright Wall panels to ensure the walls of the basement remained strong for the life of the house.

    The low point was in their driveway, and they wanted something to help prevent it from going into their home. The previous owner had a trench drain installed, but it wasn't deep enough, so the water was flooding out of the drain. So we pulled out the old one and dug it out so it would be 12in x 12in. Giving the water enough space to drain without causing any damage to the garage or home.

    During the nasty winter of 2017 we had many calls to our office from people who were having water flooding into their basements and crawlspaces. this home was no exception. Sometimes when things like this happen some home owners improvise until we can make it out to the home. That’s exactly what this homeowner did, he put a make shift sump pump in the crawl to at least minimize the water coming in. you can see in the before picture that it helped, but definitely was not a permanent solution to this homeowner’s problem. Our crew came in cleaned up the crawl installed a more efficient sump pump in a proper low point spot of the crawlspace along with a back-up battery and dehumidifier. It was also encapsulated without Cleanspace system to help keep out any water or moisture. Later on our crew came back out to finish putting in spray foam insulation.

    When Robin first inspecte this house, he knew there were big problems. Not only was the vapor barrier torn and not covering the ground, improper drain lines were directing water under the home. This excessive water lead to rot in already improperly positioned posts. Our team proceeded to install a proper drainage system, replace rotted post, and encapsulate the space. this  made it dry and healthy for our home owners.
