True North Underpinning

I honestly don't know why you would look elsewhere if you need to have underpinning done.
We had a semi with an unfinished basement. The stairs to the basement are narrow, and the basement itself was only 6'5' high (and lower in other places). We also had a crawl space under an extension to our house. We wanted to underpin it all and have a walkout so we could move normal-sized appliances and furniture in. We previously had a terrible experience with waterproofers that had dug under our foundation and caused structural damage, so I was very concerned about getting it right.
Daniel was awesome from the start. The work and the costs were all set out clearly. No surprises. The cost was roughly in line with other quotes, and without the crawlspace and walkout, it would have dropped considerably. Concerns were addressed promptly and fairly, which is key. Josh, Keith and the rest of the team were clearly experienced, and easy to get along with. Given the walkout and the crawlspace, this was a lengthy job, but they kept at it virtually every day. The few external trades that needed to come in were scheduled efficiently to keep things moving.
If you want your underpinning professionally done, this is where you go. They earn the 10-star review.
