Do you offer a warranty on your work?

Yes. We stand behind every job we do. We provide a warranty certificate for your peace of mind. This document is also very helpful if you decide to sell your home later. It shows the buyer the basement is safe and dry.

What areas in Ontario do you serve?

We are based in Mississauga. We help homeowners in Toronto, North York, and Scarborough. We also go to Oakville, Milton, and Hamilton. If you have a water leak anywhere in Southern Ontario, we can help you fix it.

Can you fix my basement without digging?

We can often fix leaks from the inside. We use French drains and special membranes to manage water. This means we do not always have to dig up your yard. We will check your home and suggest the best way to stay dry.

What happens if my sump pump fails?

A broken sump pump is a big emergency. We fix or replace them fast. We also set up backup systems with batteries. This keeps your basement dry during a storm, even if the power goes out at your house

Do you handle mold in the basement?

Yes. Wet basements can grow mold. We find it and remove it for good. We also fix the water leak so the mold does not grow back. This keeps your home safe and your family healthy.
