Basement waterproofing

Cornerstone Waterproofing did an excellent job fixing a leak in our basement. The quality of their work surpassed our expectations and the cost was competitive. The crew was skilled and courteous. They showed up on time every day, worked hard, tidied up and covered everything at the end of each day, and got the job done on time.

The final step of laying a concrete patch had to be delayed for some time after the waterproofing was complete. Their lead man explained the reasons and the risk of the concrete cracking if it were done too quickly.

We wholeheartedly recommend Cornerstone Waterproofing.

Foundation Waterproofing and pathway repair

Cornerstone was recommended to us by friends. This is a family-owned and run business that takes great pride in its work. From start to finish Saverio LoMonaco and his crew were prompt, friendly, efficient and performed excellent work. There is still one part of the work to be completed (the laying of concrete to repair the pathway) because the work already completed requires time to settle. Other contractors might have proceeded only to produce problems up the road. I highly recommend Cornerstone.

Exceptional, professional service

Saverio and his crew dug out and underpinned my basement. The service, in terms of job completion, communication throughout, finishing and even offering advice and suggesting other contractors to help complete my project. This was my first big reno and I had never been my own general contractor before. With Saverio's assistance, I was able to lower my basement floor by 24", reroute the sewage, waterproof, and build an escape access from the basement. He and his crew were fast, and he communicated with me throughout the project, which helped with peace of mind. He even suggested great, professional contractors that allowed me to finish my project. All-around I highly recommend Cornerstone.

Underpinning Project

Exceptional service. Exceptional work.

We had an excellent experience with Saverio and his crew. From the get-go Saverio was available to answer all my questions thoughtfully and honestly about underpinning our basement and never tried to push us to make a quick decision. The crew that works for him were at our house at the same time every day, entirely respectful of our neighbours and finished the project on schedule. Since the completion of our basement project Saverio continues to be invaluable to use as a problem solver when we had an issue with the city pipes outside of our house.

I highly recommend Cornerstone Waterproofing for anyone that is looking for high-quality, reliable service!

Dug down to foundation and replaced old weeping tile

We had a major leak all along the back wall of our home and since the job was complete there has been no water problems. Saverio is extremely professional and knowledgeable. the job site was left clean and neat. I would highly recommend them and would use them again

Brick replacement + Parging

We had some deteriorating bricks on the west side of our house that, quite frankly, seemed like they could become an issue down the road. My wife contacted Saverio and he came by within an hour to assess and followed up within a day with a written quote. The work started the following week and was done within 5 days.

Saverio and his team were efficient, tidy, and the job they did looks OUTSTANDING. Saverio even came back after the job was done to to personally address a couple of concerns I had (which are no longer concerns.

10/10, I have no doubt we will hire cornerstone again for any future waterproofing and basement needs that arise.

Underpinning and dropping basement floor.

Following Cornerstone installing post and beams of our home in December, they underpinned the basement in January. I have nothing but praise for Saverio and his team. They worked diligently, showed up on time daily. This is long, lengthy and dusty project and they came through with honors. I would like to think my baking helped :.) I would not hesitate to recommend them for the specialized services they perform.

A cut above what you normally get from a contractor

I spent months researching underpinners and contacting references and finally decided to hire Saverio at Cornerstone Waterproofing and I did not regret it.

I tend to get very involved with the projects and I am very particular in how I oversee a project. Saverio was very responsive on text, phone and email and always answered my questions and put my fears to rest.

Whenever I had a concern, he was open to hear me out and make and always responded accordingly by making the necessary changes.

His team works very hard and I never felt uncomfortable to have them in and out of my home. They kept as clean as possible and made sure to seal everything up tight at the end of each day. They kept consistent and good hours and did great work.

I know this review sounds very flowery but that just shows how happy I was with Cornerstone considering the amount of money I was spending and the size of the job for these small homes.

As far as price goes, his quote was pretty consistent to other quotes but I can tell you from experience that his customer service is enough hidden added value that you will also not regret hiring him.

Underpinning

Cornerstone underpinned our house, dropping it almost two feet. We cannot speak highly enough of Saverio and his crew. The job took approximately three months, and we could not be happier with the work. The crew were extremely respectful of our home, and were always cheerful and happy to provide us with updates. The quality of the work was exceptional, and for such a big job, we felt in good and safe hands from day one. We recommend Cornerstone 100%, for any job, big to huge. Great company.

Lowering Basement and Underpinning

Where do I begin.
Saverio and his team Brian and Kyle went above and beyond our expectations. They are very professional, hard working, friendly, very accommodating, always available for questions. It truly was stress free for us. They take pride in their work and so they should. We could not believe what is involved in doing this reno. They even removed our old wood beam and replaced it with a steel beam.

Saverio really makes you feel at ease even with my many questions.
We cannot thank them enough for their amazing work.
We are only sad we didn't do this years ago.
We would definitely recommend this great team.
