Roy was a brilliant sales person, answering any and all questions I had about the system, and explained the entire process thoroughly. I was in a dire need to have the service performed immediately, and Roy made all of the necessary arrangements to accommodate me, as if I were their only customer. Their price was slightly higher than other quotes I'd received, but I'm a firm believer that you get what you pay for, and it certainly applies in this case. Other companies that provided quotes for me, which will remain nameless (read: essentially EVERY other inside waterproofing contractor) were not nearly as professional, lacked presentations to reassure me that I was getting a quality product, and didn't really impress me like Clarke Basement Systems did. My basement no longer smells, and the dehumidifier takes approximately 3 days to fill, where it would only take about 8 hours before. When the basement is done, I'm sure this will improve even more. Very impressed, would recommend to anyone with a leaky basement.
