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.

Post and Beam replacement

No words to explain the professionalism of this contractor, Saverio and his crew - Matt and Anthony. Plans were to begin and finish in the summer and to do the work, the furnace needed to be disconnected and duct work taken down. Then we ran into trouble with delays with CAD designer and his contractor who could not prove he had insurance coverage and so we cancelled using him. Now it's September and we were scrambling, knowing winter and frozen pipes are soon. Looking for other options, we met Cornerstone. Saverio assured us that he would fit us in before the frost hit. With his quote, he provided his insurance liability certificate. True to his word the job was done with his great crew work diligently for 4 days perfectly timed for the heating and AC crew to arrive to put everything together, just in time for single digits temps. Honestly, it was lovely to work with this company and would never hesitate to recommend them.

Back foundation wall

Savario and this team did a fantastic job. He came highly recommended and truly lived up to his reputation.
It was a tight space to work in and they hand dug the down the foundation wall. Removed and cement blocked in an an old window inside.
The work was completed quickly and the site was left clean and tidy.

Basement Lowering and Underpinning

We were referred to Saverio from Cornerstone Waterproofing by our architect and we are so happy that we were. From our first meeting with Saverio we knew that he was honest, reliable, professional, knowledgeable and competent. The scope of our project included underpinning the entire perimeter of our basement, lowering it from 6ft to 8ft ceilings and all the other things that are involved when you lower your basement (sump pump, waste injector, interior waterproofing, new drains, concrete floor and a few extras that we asked for). Brian and Kyle (Saverio's crew) are so friendly, easy to be around and hard working. These guys are truly wonderful people (even several of our neighbours mentioned how great they were). For 6 weeks these guys came to our house on time, never complained about being in a dark and dirty basement and were so kind to our boys, playing catch with them on their lunch break and chatting about baseball. Brian & Kyle even gave each of our boys baseball caps on their last day of work which they love and wear all the time. The project finished on time and on budget and was completely stress free for us. Since they finished we have called Saverio several times to ask him questions and he is always happy to help us. We highly recommend Cornerstone Waterproofing and would definitely use them again if we needed to. By the way our boys keep talking about a snowball fight that they are going to have with Brian & Kyle??? Thanks again for everything!

Basement underpinning

Cornerstone did a fantastic job of underpinning my basement. One of the best contractors I've worked with--easy to get ahold of, accommodating and professional. Would highly recommend Cornerstone to anyone needing underpinning work.

Underpining and waterproofing

Saverio and his crew were fantastic! Very knowledgable, competent and friendly. They were accurate in estimating the time it would take to do the job and reasonably priced! My wife and I were really impressed at how fast they were and how clean they kept the job site!

I recommend them to anyone looking waterproofing and/or underpinning!

Basement excavation, underpin and new slab

I am a general contractor in Toronto. Our company does home renovations that run the gamut. We hired Cornerstone Waterproofing for the digging, excavating, beam and column replacement, waterproofing and new slab pour for a basement we are currently finishing in Toronto. Savario and his team are exceptional. The quality of work leaves nothing to be desired. More importantly, as a contractor, I had to do no baby sitting whatsoever. Savario understood what was needed from day one and lead his team through the job. Very few questions were asked and I was able to continue my work elsewhere while Cornerstone took care of this part of the job for me.

Professional, courteous, timely, organized and refreshing.

I have already included Cornerstone Waterproofing in two other potential jobs we will take on, and they only finished our last job two weeks ago!

10/10.

internal weeping tile

Saverio and his team worked efficiently and installed a weeping tile on one wall of our basement. Saverio was very pleasant to deal with, was very clear on the scope of work, did a great job, and left no footprints (i.e. excellent post work clean up). I would highly recommend to others.

Basement waterpoofing

I was very happy with the job done by Cornerstone Waterproofing.
Sevario not only did a great job in a timely fashion but he came back later to smooth out a section of the floor that was rough once I removed the old water tank.
I would highly recommend him to anyone. He's also a genuinely nice guy.

Foundation Waterproofing

Saverio and Cornerstone waterproofed the back part of our house. He and his crew were excellent! On time, honest, clean work site. Also, he adapted easily to a change in plans. Highly recommended!
