“Allmaster Home Services did a couple of things. They did some basement repairs and concrete repairs to my foundation wall, and that was excellent. They were the prime in doing my patio, and that's a fantastic piece of work. They were courteous and timely. It was just an all-around great company. I would grade them as an A+, and I have already recommended them.”
“We had some water in our basement. They put another sump pump down for me, dug down in the foundation, put pipes in, and put plaster on the concrete blocks. It was excellent work.”
“They were very courteous and punctual, and they kept me informed every step of the project and let me know what was going to happen. I've had other contractors, and I found that Allmaster Home Services was the best of any kind of contractors. I would give them an A+. I've recommended them.”
“Allmaster was excellent. They worked on my basement. I would grade them an A for their excellence.”
“They were overall very professional. The owner came out and gave me the quote. He was a very genuine guy, and the workers that came over took care of what they did. I would use them again for a project. They put some high beams in my basement to hold back the retaining wall. I would grade them an A. I would definitely recommend them.”
“They did some foundation repair for my uncle's home. There was a slope and some cracks in the foundation, and as far as I know, the job worked. We chose them because it was a family company, and they were honest, on time, and professional. I would grade them an A+.”
“Allmaster did some foundation work for me. I had a crack in my foundation that I needed repaired. and they pulled up some roots that had initially caused the cracks. They got the job done while I was out of town. We recently move and spruced up the house, so that we could put it on the market, and it was good that they could work on it while I was miles away. I would grade them an A+.”
“Allmaster was here leveling out the subfloor. I thought they were very professional, and they were clean. They were really quick with the job. I can't remember the guys name that came out and gave me the estimate, but he was really well-spoken. You could tell that they had been doing it for a while. I would grade them an A+; they were really great.”
“They did exterior masonry work. They were easy to work with. I would grade them an A.”
“They did a walk-up project in my basement. It was concrete work. They were on time, they called before they got there, and they gave me feedback. Everything was satisfactory. I didn't have any problems. I would grade them an A.”
