We had a pretty significant dip on our walkway that presented a tripping hazard so we had Quattro come and level out the cement. What an amazing job! Paul was prompt, courteous and extremely knowledgeable. Our walkway is as good as new and I don't have to worry about anyone tripping anymore! We are very happy with the work and highly recommend their services.


Quattro Contracting recently raised two concrete slabs for us. We found their service to be prompt and friendly. They fully explained what they were going to do, arrived on time and stuck to the original estimate. We were very pleased with their work.

Just thought I'd share that we had our basement sealed and waterproofed by Quattro Contracting Inc. located here in Erin and they were awesome. Very professional, very friendly, pricing was more than fair and they took a lot of pride in their work. If you have issues with water coming into your house I would highly recommend reaching out to them.
