"We hired Brennan and his company when he first started his company, years ago. We had to structurally change the living room and dining room prior to renovating the kitchen. By the end of the project we had an entire open concept first floor, and brand new kitchen. Between the workmanship, communication, dedication to show up on time, when they said they would, I would highly reccomend B LaGrassa Construction."

"I needed plans for a two-car garage of a certain size and roof pitch. I could not find stock plans of specifically what I wanted. Richard was very prompt and helpful, produced the plans and arranged for an engineer's stamp."

"Costs increased about 10% over estimate, work was well done and the final product was professional and well-built. Communication could have been better, the builder promised weekly meetings but that didn't happen. All in all, we were happy at the end of it all, and all questions were answered and all finishes to our satisfaction, which if you've ever worked with a contractor before, you know isn't a given. 5/5 would work with them again, the fireplace mantel and threshhold was particularly well done."
