Over the past 6 years we have been trying to prevent water from filling our window well and basement. The slope of the paved ground outside our building allows our neighbours downspout to pour onto our property. Other contractors had tried and failed and I was frustrated at the money I had previously wasted. Peter spent a lot of time figuring out how to solve out problem. It was obvious he cared about doing the job right. He kept me informed throughout the whole process with emails and photos and patiently explained everything. I highly recommend him!
