You installed a Sani-dry system in my basement in Dec '13. Since this is mostly a warm weather issue, it is a bit too early to tell if it will significantly reduce or eliminate my efflorescence issues.

I realize you were behind with all the bad weather this fall, but it took two months to have your electrician come out and finish the job (switching from extension cords to hard wiring & a generator hook-up). I had to call Bill to prompt the electrical work, so it seemed like our follow-up appointment got lost somewhere. Worth the wait though, as your electrician's service was every bit as professional as the installation crews - we were very impressed. It also didn't hurt that the bill came in ~$2,000 below your original estimate - we appreciate the integrity.

Your system has solved a serious water problem that had developed in a basement that hadn't leaked in 45 years, working flawlessly to keep us completely dry through several major storms this fall. Thanks for making our basement a useable part of our home again, and bring on the spring melt!

In closing, I have never seen a combination of professionalism, quality system components, and attention to detail like this before in a contractor. Thanks for doing a great job, and feel free to use us as a reference any time.

Besides being courteous, on time, and professional, the crews were also gentlemen and the kind of people you are not only comfortable with, but glad to have in your home. On a few of the days they worked at our home, my wife was there alone and was extremely complementary of the crews. That's worth a recommendation all by itself!

It was my intention to write a letter about the person who was in charge of installing our system. I failed to do that and have since forgotten his name but I do want you to know that he was outstanding. When they finished installing my system, my husband inspected what they'd done, seemed to approve, I paid them and they went on their way. Minutes later, my husband complained about something and had them drive back. And this was at the end of a long day. Without going into the lengthy, tedious details, I felt your installer handled this annoyance with such professionalism, grace and patience. I KNOW he had to have been annoyed. Heck, I was annoyed! I appreciated that he didn't let it get the best of him and was impressed by his unwavering professional demeanor. I remember that he's been with your company for more than 20 years. I understand why you've kept him that long. He MUST be one of the reasons you're rated so highly. Treat him well! By the way, I think my husband's complaint was probably unwarranted and I, ultimately, sent them back on their way without making the change my husband was suggesting - even though your installers were willing to do it.

Joe is good listener and salesman. He did not push matters like some salesman do. He immediately responded to any phone messages i gave him. There are not too many persons with Joe's qualities, so you better keep him for a long, long time.

Job Stories From Killingworth, CT

SmartDrain Installation in Killingworth, CT

Garrett P. in Killingworth, CT was noticing leaks were creeping into his crawl space. Needing an immediate and quick solution, he gave Connecticut Basement Systems a call, and we were happy to go right to work!

Our System Design Specialist quickly deduced that the SmartDrain Crawl Space system was the best solution to Garrett's problem. The SmartDrain is a system that is installed to alert customers of any excess water entering the crawl space. It is usually installed with the CleanSpace crawl space liner and will alert you if there’s a leak, draining the water until you can fix it. Best of all? Its lid is airtight, which allows water to drain, but doesn't allow moisture to enter the crawl space.

Garrett was left knowing he has a protected crawl space and we left knowing we installed a product that would help our customer for years to come.
