We bought an auto repair shop with an old oil tank that left contamination under the floor and footing. SOS handled everything perfectly. Cam and Levi are friendly, professional, and extremely knowledgeable. Communication was clear and honest — no runaround, just straight answers. If you need remediation done right the first time, these are the people to call. As shop owners, we know the value of fixing things right — and that’s exactly what SOS does.

Cam and his crew were exceptionally easy to work with. Our garage was in bad shape and we had planned on utilizing SOS and the team for months. They came and demolished our garage in such a professional manner. Cam came and worked hard all day because he didn't want to let any of his clients down. Even while the night prior there was a huge windstorm and he had to delegate all the various jobs that need prioritizing. The clean up was done effectively and the team works fast and they are a lot of fun as well. Last minute Ryan and I decided a deck would be a great addition. I literally just asked Cam and he said he would come back the following week and build us a beautiful deck where our old leaky garage once stood. The cost of his work is very reasonable. I cannot thank him and his team for all the hard work they did for us!! Lots of appreciation Leiann and Ryan

When we found a large area mold in our attic and basement, we reached to SOS. During the work, they had found more hidden mold and means more work than expected. They returned our home next day and got this resolved properly and thoroughly. We are so satisfied and feel grateful to have SOS team to deal with it. We will strongly recommend SOS if someone encounter the similar situation and need professional help.
