After getting several estimates, I went with Jamison Basement Waterproofing because of the knowledge of the project manager Steve Custus. He didn't attempt to pressure me to sign for the estimate the day of allowing me time to think the job over and pricing.

Now that the job is complete, I am happy that I have chosen Jamison because after this past week of rain my basement has been dry as a bone thanks to Steve and his team!

They arrived earlier than scheduled so they could get the job done before the rain started, which allowed them to do a less messy install of the pipe and netty pot. Very cleanly done which we appreciate.

We have had a water problem in the basement that has gotten progressively worse over the past 10 years. The water inflow was unbelievable. It FLOODED our basement and we had non-stop problems and with our old sump pump, after a torrential rain would have 8 gallons every 13 seconds--that's right, 36 gallons of water coming in a minute from hydrostatic pressure. It sounds corny, but we thought we would never get it under control and were at wits end. A friend who is a contractor did research, and said Jamison was the only company to use. Long(er) story short(er), we had JBW come out and waterproof the trouble rooms. We had torrential rain for the first time since installation, and this is the FIRST TIME IN 25 YEARS THE BASEMENT HAS BEEN DRY. Not one drop of water. Needless to say, this was the smartest thing we have done for the house, and wish we had learned about JBW a long time ago. You won't go wrong with this company.
