"Joe was great. He provided and estimate and completed the work. He was great to work with as he maintained communication with us while on vacation. He wanted to ensure we were getting the right product for the job. I also want to mention that most other contractors avoid these small jobs which is frustrating to us. Iâ m very happy with Joes work and will use him in the future on other work I plan for the house."
