"I highly recommend Groundworks for foundation concerns. They were very prompt with returning my call and providing a free inspection. I had concerns for my 103 year old home, especially a section of the foundation. Their Inspector, Bob Bloom, arrived on time, was professional and experienced, took time to answer all my questions (thank you for not rushing), and provided me with useful feedback on my foundation and options for repair. Bob gave an honest assessment with no sales pressure. Although I decided to defer foundation work at this time, I will definitely use them in the future."

"The plumber showed us a trick for how to clear the food trap using the garbage disposal and water pressure, which I really appreciated! He also, with permission, came early so punctuality was great. Only downside is this business is pretty expensive, twice at least what I have paid out prior plumber."
