"McLay was fantastic! Great people and fast service."

"After getting different quotations from different construction companies, even Home depot, AGL gives us reasonable pricing options. They did such a good job on remodeling two of my bathrooms we had a special request canceling a door and opening another, and the outcome was amazing. We went from having one bathroom and a half to two full bathrooms. After seeing the amazing job that they did with the bathroom we decided to also remodeling our kitchen with them it was the best decision."

"This big job got more complicated, but this pro was determined, had a positive outlook, and finished everything to perfection. Thank you, John’s Plumbing 😊"

"Andreh completed the job in 1 1/2 hours, more quickly than he had estimated (and his time estimate, 2 hours, was at least half of the next lowest, 4-6 hours). He installed the replacement parts my husband and I had purchased, and brought the part we had forgotten about. He didn't (as one plumber did) deprecate the manufacturer of the material he was installing. He was on time, and left the bathroom in better condition than he had found it. He is a pleasant person, clean and neat in appearance. We look forward to using his services again."
