Hired on Thumbtack

Haven't had the actual project done yet, but was so impressed by project manager Edward Durkee that I hired him on the spot. He thoroughly explained the problem to me and took lots of time to go through the entire area with me so I could be sure of exactly what would be done, what we would need to move, etc. He also supplied us with an excellent resource for getting the supplementary work, like drywall, etc., done, and that person praised Edward very highly. Edward has been following up with me via phone and email, and has given me lots of valuable information for us, and for our property management agent. This is a huge job, but I'm confident it'll be done right, and that it'll be followed up for years afterward.

While we did not pursue a fix with Groundworks due to our situation, I was impressed by their speed to assess, professionalism and communication.

I noticed cracking outside of my garage in the bricks and it started getting worse. Mike Gold was great!! He made the entire process of getting my Home's Foundation repaired easy and even had 0% financing! Gabriel Amaya handled the install. Him and his crew were very professional and even finished the project a day early! I highly recommend Groundworks for anyone with foundation concerns.

We recently experienced some flooding in our basement, and not only did we have to deal with cleaning and repair, but also with figuring out how it happened in a relatively new build. We called Groundworks to see if they could help diagnose the problem. Kalen came to our home and conducted a thorough inspection and within 30 mins had figured it out!! To our great relief it turned out to be a simple patch job which he walked us through and also gave us some recommendations about the positioning of our outside rain spouts. I think the mark of a great company is how they treat their customers even the ones that dont end up needing their services. Kalen was courteous, professional and great to work with and would happy to recommend him and Groundworks to anyone.
