Initial repairs went fine, but trying to get anyone to respond to inquiries for a follow-up the next year have been a nightmare. No response via several methods, over and over again. Good luck.
Edit: a month later and 3+ months after my initial issue, it still has not been fixed.

Awesome experience with Derek. The blocks at one corner of our basement were bowing, so Dereck replaced the blocks, core filled them and waterproofed the outside. While he was here he noticed some holes between the blocks on the other side, and fixed them without charging. The job site was thoroughly cleaned afterwards. Highly recommended.

Worst job I have ever seen, not only did they not parge our house properly, they damaged my brand new windows and door. Tried working with Derek and for 6 months to have it repaired, it never was even though he agreed the work was not done properly. He said he would refund my deposit, which he didn't and he is now ignoring my emails. Don't waste your money or time.

I contacted D & S Masonry to have some work done for my Grandmother's chimney that was in need of repair. From the first point of contact up until the job being done, they were outstanding! They quoted a fair price, and showed up in a relatively quick turn around time. They went the extra distance to make sure they had the proper brick to match the existing, and even spent extra time cleaning up any debris from the work they did.
While they were working on the chimney, they let us know about a minor issue with the roof of the house, which we addressed with the roofer.
The workmanship was very

Professional and courteous. Did an upstanding job with our basement and offered competitive reasonable prices. The crew was thorough and put everything back the way they were prior to the reno. Derek was informative and didn't mind all my questions.
