Cornerstone Waterproofing

This message is long overdue!!!! Last year I hired Saverio and his crew to fix a leak in my basement. After meeting with several other contractors, I chose Cornerstone Waterproofing for the job. Saverio was very polite, informative, punctual and fair. He followed through on his every word, including a thorough clean up and I have not had a problem with my basement ever since he worked on my house.
As a single, female homeowner, I never felt that Saverio was interested in ripping me off, nor did I feel embarrassed by my ignorance when asking him questions about the work required.
I couldn't recommend him more!

We used to have streams of water running across our basement floor during and after heavy rains, so as part of our home renovation, fixing the basement drainage problems was at the top of the list. Not only did Saverio and his team from Cornerstone deal with replacement of our basement slab and all of the necessary under-slab drainage and plumbing, they also took care of the installation of new steel beams and posts to open up the basement area and hydronic heating pipes in the new slab as well. They were very easy to work with, were always on site when they said they would be and got the job completed on schedule and at a very reasonable price. Even when there were unforeseen issues during the job, they dealt with these without any major drama to make sure that we didn't lose any time.

I can also say that it's been about 2 years since the work was done and our basement has been bone dry since then. The weeping tile, sump and pump have worked flawlessly at keeping the water out of our basement and our floors nice and dry.

Saverio and his crew were amazing. From start to finish everything was perfect. Our family highly recommends this company. Honest, professional, and skilled. The finished product was beyond our expectations.

Saverio was the name of the man who came to fix my house, which had been flooding whenever it rained, and he did an absolutely fantastic job! He fixed the leak that was causing my basement to flood, and I have never had the problem since.

On the recommendation of another company we had Saverio carry out concrete restoration on the foundations for the porch and steps at the front of our house. Savario did a very professional job. In fact some construction workers on a nearby home had been watching him and came over to tell me how impressed they were with his work! Saverio was punctual, polite, and cleaned up afterwards. All this and at a very reasonable cost.

After interviewing several waterproofing companies, I chose Cornerstone Waterproofing. I chose them for their honesty in writing a very detailed quote along with the name of the product to be used. When the job started I found Saverio's crew to be very well trained. They did their job, were always pleasant, left a clean job site, and followed all written requests according to the quote provided. It is just too bad their work does not show once the job is completed. This crew would make any company proud; they performed their work above and beyond what was required of them and finished on the date provided. I have nothing but praise for this company, and especially for the leadership of the owner, Saverio LoMonaco. Yes, I will recommend this company today, tomorrow and well into the future.

The Cornerstone crew were punctual, courteous and kept the job site clean and tidy on a daily basis. The job was finished in less days than were quoted and unforeseen complications were addressed carefully and without hassle. I would highly recommend Saverio's crew - he runs a tight ship and takes pride in doing the best possible job.

As most can attest waking up to a flooded basement is not the ideal way to start the week. I had no idea of who to call so a friend referred me to Cornerstone. After meeting with Saverio & going through the step by step process it was very clear to me that he cares, takes pride in what he does & wants the customer to fully understand what each step entails. The were very organized, clean & most in important on time with their deadlines. I would heavily recommend them as you would be crazy not to. I used to hate the sound of rain, but I now can enjoy the rain once again.

Hats off to Cornerstone, Saverio & his team.

I don't hesitate to recommend Cornerstone Waterproofing to anybody who asks about the job (and even to those who don't ask!) All my neighbors have commented on how well the job was done, in the middle of the winter, with minimal impact on the neighborhood. The team was here working like a well-oiled machine until the job was done. Completed within the estimated time and at the quoted price despite it being a much more involved job than expected. Saverio was a pleasure to work with and was always willing to go above and beyond what was expected. High quality work with excellent follow-up. Thanks so much!

My wife and I just had our first child a few months ago, and it became quickly evident that after the arrival of our son that we were going to need more space as we both work from home. Our options were to add on to the back of the house or utilize the basement space that was there. Like most north Toronto homes, our basement was wavy and not as low as we would have liked it to be with very bulky columns supporting our main beam, but fortunately we saw the potential in it. We had several quotes on benching, underpinning etc., but it was Cornerstone that suggested that it may be wise to simply flatten the floor, remove the columns and replace them with steel posts and to have the pluming moved to where we wanted it. This solution saved us thousands of dollars and still provided us with a very acceptable 6'8" clearance and provided an additional 600 sq. feet of living space for our family. They were always on time, and very professional and kept me informed about the inspection process. While I wish that the finished floor could be even flatter, I understand that it was the drains that dictated the slop. I would recommend Cornerstone to anyone.
