"Extra Small Window Air conditioner installed beautifully."

"Overall Builders and its owner Robert were fantastic. Easy to work with, extremely accommodating, competitive pricing and the quality of work was superb! The tile pattern we chose was extremely challenging and Victor, Robert's tile guy, nailed it! We will, absolutely, use Overall Bulders for all our home remodel/repair needs in the future!"

"Kevin was super friendly and knowledgeable when it came to our repair. We had a pocket door that was stuck shut and he was able to open it, do the repair, and even found why it was so creaky and fixed that issue. What I loved most is that he made sure he worked in a clean manner and even tidied up before he left. Will be recommending the handy veteran to my friends, family, and clients. "

Everyone of the workers and managers of the job showed up on time and got our job done on the specific schedule we were given. The quality of the work was top notch! The entire team was a pleasure to work with!"
