paul valerga2024-07-10This is the 2nd time I’ve used CBS for waterproofing needs in my basement. The first was over 15 years ago and that system is still operating flawlessly. Unfortunately I’ve had some issues with the French Drain pipes that were originally installed many years ago (not by CBS). Although a complete basement rip out could have been warranted, with Daniel’s help we were able to figure out a way of fixing the problem without the stress and high cost of demolishing my finished basement. With the amazing help and support from Jessica, a team (lead by Dave and Tony) was sent to me on short notice and did a great job installing a second pump system which was able to reroute the water that was stuck under the floor and which seeped into the basement through the cove joint every time it rained. CBS is reasonably priced and does a great job making sure the work is done correctly and properly. I highly recommend CBS to anyone that has water issues.Ryan Mimnagh2024-06-24Complete Basement Systems was a pleasure to work with. They responded in a timely matter to questions I had when preparing the scope of work and the schedule. They were on time and ready to go as discussed and actually finished slightly early. The job was handled professionally, and I'd use them again if I had to but I'm not expecting to!Judith Scholl2024-06-18I was very pleased with the work that was done on my basement wall crack. Anthony and his partner came on time, the job was done in a professional manner, cleanup you would never know they were there. I highly recommend Complete Basement System over any others that claim they can fix your wall leaks. They don’t use paint to cover up the problem, it’s done by injection. Best of all, they guarantee their work, who else does that.UltimateDisneyFan282024-05-01Great job. Showed up early ready to work. Very near and efficient. Cleaned up well. Very happy with the job.Mark S2024-04-06To fix an ongoing water leak that was getting worse which I thought was entering under the window frames in the basement CBS identified the problem & suggested a cost effective solution to dig out 2 window wells several feed deep to make a dry well, channeling excess water far down into soil. When they were doing the work they also located & sealed a foundation leak around the area the cast waste line came into my home which I did not know was also contributing to the water in the basement. They came on time & finished quickly. They were professional & cleaned up before leaving. One other point. Before CBS evaluated the window leak I had several other “professionals” evaluate the issue & they advised I either need a French drain system or digging on outside foundation to reseal. Neither would have solved my problems & would have cost thousands more. I am happy with my decision to use CBS & would recommend them.Jean Ahlert2024-04-03I had my two window wells dig out and gravel added. The water test and need to inject the wall. It has been raining for 3 days and the basement is dry. I'm so happy with the two man that came and the GREAT job they did.Naomi Knee2024-03-08CBS was professional and efficient when they installed our French drain system. They answered all our questions and always got back to us.Alisha Anderson2024-02-29They did a wonderful job. My in-laws are pleased with the job that was done in their basement. My mother in-law had nothing but good words to say about their workmanship. They're trustworthy, friendly, reliable, and do a great job in her words. Thank you so much for helping them get the basement together. I highly recommend this company.Freddy Falcones2024-01-25Excellent and professional service.
