They were the only company that came out to assess before giving an estimate and helped us see that not "one size fits all" for back up sump batteries. Other just gave us a price without knowing anything about the size of our house or anything.

Yves M. Yves M. Donalda

As a homeowner, I found the pricing high.... especially in our case where we weren't expecting this kind of work needing to be done... it is quite a kick in the teeth. I appreciate the consideration Martin gave us on the pricing, yet still high considering length of work, number of workers and materials.

As a satisfied customer, I can appreciate the costing factors as the crew work VERY hard, the job is difficult and the situation (crawl space) is unforgiving. Couple that with the lifetime warranty, and I can accept the price.

In the back corner of my basement the block foundation is wet down by the footing when there is a large amount of rain....which lately is all the time!

Project Location: Chatham, ON

I used a home radon monitor that showed levels ranging from 100 to 300 in the basement over a course of a week. I want to reduce my radon levels to as low as possible since my family lives in the basement unit. I have not done a professional test, but with these readings I want to install a mitigation system anyway.
