Basement Lowering and Waterproofing

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.

Waterproofing of basement + new drains

Saverio at Cornerstone is another one of those rare contractors that not only gets the job done well, but handles the business side of his work delightfully.

We own a downtown Toronto semi-detached home that was built almost 100 years ago, and the basement was always damp, had sloping uneven floors, low ceiling height, and old clay drain pipes. We wanted to make the basement dry, flat, clean, and to gain as much ceiling height as well could, while replacing all of our old drains and preparing for a finished basement.

Saverio at Cornerstone delivered all of it in spades! He arrived on-time for the initial quoting of the service, and knew exactly what needed to be done. He provided a written estimate for his work, and gave us all the details about what each line-item meant, and why we should consider doing it. He didn't try to "sell" us at all, just delivered the facts, and gave me the sense he had our best interests in mind.

We gave him a 1 week deadline to get everything done while we were on vacation, and when we arrived home everything was done to perfection. He kept in-contact throughout the week explaining what had been done and what still needed to be completed. We also gained the new uniform (higher) ceiling height that he said we would, and we were really happy with that as well. He even pulled out the half-assed job that a previous company we used to waterproof (also found her on Homestars) under out stairs, and replaced it with the full system he prescribed for the rest of our basement at no extra cost.

Overall, don't hesitate to use Saverio... you will not regret it.

Basement underpinning

Saverio at Cornerstone Waterproofing is one of the few great contractors out there. I have worked with a lot of different contractors on many different kinds of reno’s and Saverio is by far was one of the easiest to work with. I interviewed many different underpinning contractors to find the right guy for what my engineer requested. Half of the contractors didn’t know how to do 2 of the main structural components requested by the engineer - angle iron beams and vibrapack underpinning. These were common for Saverio.

He came in on time and on budget. The job was completed in 3 weeks where others quoted 4-5 weeks.

His crew; Kyle, Kyle (yes, 2 Kyle’s) and Charlie worked very hard and long to complete this on time. They showed up at 8am every morning and worked as late as they had to - sometimes as late as 6:30! They were clean, polite and caring.

One of the key components that I liked and was comforted by was that Saverio worked with the crew every single day - he didn’t just check in every now and then. He worked just as hard as his crew. To me this is so important when choosing a contractor.

I would have absolutely no problem recommending Cornerstone Waterproofing and already have.

Basement lowering and radiant heat installation.

I have worked with many contractors for many years and there are not enough superlatives to describe the quality, attention and absolute fairness Saverio LoMonaco brings to his company. His calm, attentive demeanor allows you to make the decisions needed to do the best job possible within your budget. The crew is hard working and honest. I have no reservation in giving Cornerstone Waterproofing the highest endorsement one can give. We have more projects to do in the future and I won't consider using anyone else. Also, on a personal note, I now consider Saverio a good friend and intend to stay in touch. Thanks Saverio to you and your associates for your excellent work.

Cornerstone is truly exceptional in both the quality of their workmanship & professionalism. After an enormous amount of research & meetings with almost a dozen waterproofing companies, it became clear that Cornerstone had more exacting standards of workmanship than ANY of the other contractors we had met with, including those which are considered to be the best in the city. Saverio's quote was either slightly lower or significantly lower than that of the other contractors, while his waterproofing solution was BY FAR the most comprehensive of any that had been proposed to us, including those from the few waterproofing companies that are considered the best in the city. No other contractor was prepared to do the work as comprehensively as Saverio did because, we were told, it would have been too labour intensive & costly. Saverio is very picky about the quality of his work, which is exactly what you want from a waterproofing contractor. His work was absolutely excellent, which has bought us complete peace of mind that our waterproofing issues have been fully addressed. The friendliness & professionalism of both Saverio & his crew also made them so easy to work with & a complete pleasure to deal with.

I am beyond grateful that we discovered Cornerstone & have already recommended them to all my friends, relatives & colleagues at work for any waterproofing issue they may have. Huge thanks to you, Saverio.
