Cornerstone Waterproofing

Sevario and his team rebuilt our front basement wall in the fall of 2012. They did, in short, a terrific job. What was once a crumbling 100-year old mess was replaced by a smart looking, strong new concrete block wall. We've dealt with other waterproofing people before and we won't ever bother again with anyone but Sevario. His team were hard working and efficient and were respectful and polite.Let's face it, I doubt that most people would want to rebuild a basement wall when a new kitchen, say, would be much nicer. But we had to do it, and Sevario and his team did a great job. Hire this guy and his team!

We've had Savario and his crew in for two jobs over the past two years to do some waterproofing work both outside and inside of our home when outside waterproofing wasn't possible. They have been so fantastic to work with - finish the job according to estimates, on time, courteous, reasonable cost and pay attention to details. This was especially true when the inside waterproofing was necessary since it meant taking out drywall and flooring. Savario was great with recommending a sump pump and a city program for a rebate for the work we needed to do. I would highly recommend Cornerstone.

I have had Cornerstone Waterproofing work on my house on two occasions. Once to waterproof the leaks in the basement and the second time to lower the basement for renovations. Savario and his crew are knowledgeable and efficient and polite. I highly recommend them as they work is also top notch!

Cornerstone recently completed a new garage floor for me, and I'm very pleased with the entire experience. Saverio and his crew were all very friendly, straight forward and easy to work with. The work was completed exactly as described in the contract, and quickly. They started the day they said they would and worked every day until it was complete. I mentioned to Saverio I was concerned about cats, skunks, racoons & squirrels walking through the new wet concrete, only to come home and find the garage baracaded off with temporary fencing he had errected. That's an example of the care Saverio takes and customer service he provides. I would highly recommend Cornerstone to anyone looking for a no hassle contractor who does excellent work.

What a wonderful experience we had with Saverio. He was professional and efficient. He handled all aspects of our reno and we were pleased to leave matters entirely in his hands.
We highly recommend him; his follow-up work has been greatly appreciated.

Our basement had been gutted, but due to circumstances, had remained that way for some time. Before finishing, we knew we needed to get the base frame into shape. We invited four companies in to take a look and give us their recommendation regarding waterproofing and floor leveling. 3 of the 4 companies recommended very similar solutions and were all very similar in their quote. Of those 3, we chose to work with Saverio, as he was very personable, communicative, and clear. We do not regret our decision! Each morning, Saverio was there in person and took the time to review the work with us, make sure we were happy and had our answers questioned. On the one day I had to leave the house early, Saverio called in the evening to check that we'd looked over the work of the day and make sure we were happy. They went above and beyond for us, removing and returning our washer, dryer, water, furnace. Of all the companies we talked with, Saverio was the only one to mention the rebate we could get from the city and how to apply for it. We are very pleased with the work, which was done exactly to schedule.

We had cracks in our basement walls resulting in water leaks and had Saverio come to look at the work. He was able to come quickly and gave us honest advise on how to fix the problem. I would recommend this company.

Top quality workmanship & peace of mind -- that's what Saverio & his crew deliver.

CORNERSTONE WATERPROOFING delivers 110%, Grade AA work!

I had to repair my entire foundation due to extensive water penetration. I did it in 2 stages and when the 'famous' group could not complete it, they referred me to Cornerstone; the only company they would recommend.

Saverio and his team exceeded the highest of standards.

Saverio was on site and in the trenches during most of the repair. He groomed his team to be highly technical, organized, thorough and extremely competent. His workers adore him and it shows in their attention to detail, integrity, cohesiveness and full out professionalism.

Saverio is dedicated to quality control. He was meticulous in setting up the work area. I was awed by his tidiness and precision. He did not compromise or cut corners - as a result, unlike with the first bunch, there was no damage to my property or the neighbours' property.

From my first conversation with Saverio to the day he left, I found him to be responsive and dependable.

Saverio embodies integrity and character. I am happy to share pictures or answer questions about his work.

We got in touch with Saverio via a recommendation from a friend. Our basement was emptied of garbage and debris, torn to pieces and dropped 4 inches. Before we had issues with an uneven floor, water seeping in and musty smells. Now it is bone dry and perfectly level. Saverio's team even tore out extra unrelated pieces and changed the locks on my doors without charging an extra dime. More than once I found Saverio at my house late in the evening cleaning up for the next day and they even came and did some work on the weekend too. Solid company, you can't go wrong hiring them.
