As you can see I am a satisfied customer. I worked in Retail as a Service Mgr/HR for a number of years. Everyone at your company showed a pride in not only what they do but the company. It was refreshing to have these young people taking care of me like they had been doing it for years.

Shawn Bent is a very nice man, we had a little snafu, it was dealt with, no fuss no muss. Very friendly man, nice and personable. If I ever had any other work to be done I would hope that Shawn would be doing the work. I was very impressed with the man. He was training a new worker and I thought that they worked very well together. As you can tell I am very pleased. Thank-you.

Job Stories From St Thomas, ON

Radon Gas Solution in St Thomas, ON

Radon Gas will seek any opening in a basement to enter the home. The air pressure in a basement is usually lower than the outside as air will migrate to the upper levels of the home during the heating season.

Cracks in the floor and walls are one of the main culprits to let radon gas into the home. Advanced Basement Systems wall called to a home in St Thomas, ON after the home owner found high levels with proper testing. Large cracks under the carpet were discovered during the inspection. The mitigation included repairs to the cracks and a proper powered vent system installed.

The home is now testing lower levels of Radon gas and is safe for the home owners.
