We have a sunroom addition that had been installed by a previous owner. Due to a combination of poor soil and what appeared to be supports installed at inadequate depths the structure had settled. We hired Clarke Basement Systems to install their SmartJack system to stabilize the structure. Using the SmartJacks they also raised one of the corners of the sunroom which brought windows and doors back into alignment. It was like night and day to have doors that no longer stuck when attempting to open them. From meeting with Ron who came to assess the job and provide a quote through to booking and work completion communication was excellent. The job took two days and it was heavy work. It gave us added comfort that Don Clarke (owner) was on site throughout, working with his installation team. He was very patient and courteous in walking us through what they were doing as the job unfolded. Our experience was positive and we would not hesitate to hire Clarke Basement Systems again should the need arise.
