Here is what our customers had to say....


T. Quinn Sharon, MA 06/29/2020

We bought our 100-year-old home in Sharon two years ago and for the first year had consistent flooding in our basement with very heavy rain. We found O'Sullivan Brick and Stone online, and John put in a basement drain, Repointed and parged our fieldstone foundation, and installed two Drywells. I've waited a year to write this review and can confirm we've had no water in our basement since! We will Certainly hire John O'Sullivan again if we have another stonework project.

Mr. O'Sullivan is a true "stone" artist! Honest, reliable, and hardworking!

We found O'Sullivan Brick and stone online and hired them to clean and waterproof our dusting basement walls. They did an excellent job. They are fast, efficient and reliable. 

I would certainly hire them again.
