Aquaseal Basement Waterproofing Contracting Ontario

We could not be happier with the service we received. Each step of the way we were given all of the details and all questions were answered very quickly. After understanding we had been struggling with a recurring issue trying another company, they found space in their schedule immediately to fix the issue with a 25 yr warranty that is transferable. They fixed the issue, cleaned up after and were always careful while bringing equipment in and out of the house. They were willing to take the time to explain the repair in terms we could understand. We would definitely recommend their services and would use them again should the need arise.

We had rod holes leaking. Pierre came and sealed them up. One has started leaking again and Pierre is coming back to repair. Happy with service . Will use his services again if ever needed.

My tenants complained about water in the basement, and my handyman couldn't find the source of the issue.
Aquaseal Oshawa came in the day I called, found the crack in the foundation and repaired it the next morning.

They gave me two options to fix the crack, 1 inside, and 1 outside. I chose the outside option as it's less intrusive to my tenants. After completing the excavation & repair they power washed the back deck and driveway to remove any signs of them being there.

They addtionally sealed up a poorly sealed mandoor with fresh caulking to prevent water from getting in the basement through there.

I will definitely call them again if needed.

I had a full hairline crack in my foundation wall below my basement window that had been previously repaired but continued to leak when there was any heavy rain. Pierre and his team installed the Aquaboard wall treatment & under floor drain system in no time at all along with a 25 yr guarantee. They knew exactly what to do and were very professional . They will be the only team I deal with in the future for any foundation issues.

inside basement under floor weeping tile drain system and wall treatment and install cold cellar venting to outside.
Had issues with drain backup.
The issue we had was not related to any previous work that was done at your home before and Pierre helped you to source your problem on Sunday visit at no charge.

I had a leak in my basement and it with minimal damage to my finished basement, Aquaseal was able to locate a wall crack in my foundation which they quickly repaired with epoxy injection. Not only did they repair the wall crack internally, externally, they installed a french drain and a vertical drain to house weepers at the exterior rear flagstone patio. I was worried about the esthetics of installation on a flagstone patio but Pierre explained everything to me and fixed the problem while making the patio look great! They were fast, efficient, listened to my concerns and fixed the problem without a mess. I am very happy with Aquaseal and would highly recommend them!

Pierre was fantastic, professional and accommodating. I noticed water behind the furnace in our basement and needed it repaired in a hurry as we wanted to put our house on the market. Pierre was onsite the less than 12 hrs after I called him and on a Saturday. He quickly assessed the problem and came up with the best way to address it. He had a 5ft wall treatment and inside floor drain completed in no time and left the area clean and dry!! I would highly recommend AquaSeal for anyone who wants a true professional to give them peace of mind with a quality repair and a 25 year warranty!!! Thanks again Pierre!

What was done: 1 foundation wall corner crack previously worked on by others with hydraulic cement repaired with Aquaboard wall treatment and underfloor drain system.

Overall review: Arrived on time, worked quickly and efficiently and explained all work being done clearly. Great warranty too.

We were extremely impressed and grateful that Pierre from Aquaseal came to our rescue to repair a crack in our finished basement so quickly. The rain had been pelting down recently, leaving our basement carpet wet. Pierre had to cut open the drywall, remove the insulation and assess the situation. He did everything that needed to be done in a professional, efficient and most importantly, permanent manner. He explained what needed to be done, determined the cost, completed the work and left our property clean and dry. Thank you for your expertise. We eould recommend your company to anyone who eould require you services.

Multiple foundation wall cracks repaired by epoxy injection for my house. Terrific and effective results. Recommended Aquaseal team to my daughter who is also delighted with the service. I used the service again recently on a new problem and received the same great service from Pierre.
