"These guys were awesome!! If you need foundation work, call them first. I have a raised foundation and it was off by 3 in. in some area's. I went with this company because they do not use contractors or sub-contractors. Everything is done by the company! I had one window break and they called me immediately about it, cleaned it up and got the plywood to cover the opening. When they gave me the quote I didn't quite have the money. I called them apprx 10 mos later to give the go ahead with the work. By that time the prices had gone up ALOT by 10K. But they honered the 1st quote because it was under a year old. And a good warranty!!"

"We had a second story deck that was leaking water into the garage. We got 4 companies to come and give us a quote. Two of them were cheaper but they seemed as puzzled as we were about what to do and could not guarantee from future problems. The other company suggested rebuilding the entire deck and was way out of budget. Ryan from Monarch Custom Coatings came with a sample that had several layers to waterproof the deck - we were very impressed that he was very knowledgeable and has a lot of experience with this type of work. He and his crew worked very hard, always professional, prompt, courteous, and our deck looks amazing now. We were so happy with them that we hired them again to redo the garage floors. We have had bad experiences in the past with contractors, so we know that finding a good, reliable, and honest one is very hard and rare. We highly recommend Monarch Custom Coatings!"

"We met with several companies before deciding to go with Palm Construction and we are very happy we chose them. Omri and his team were on time, professional and gave us a great price. They replaced our roof in less time than we even hoped! We are so impressed with the quality of work they did and for a good price! We highly recommend them!"

"Perfect!!! We originally d to repaint the whole house. Since that was out of our budget, we asked Tony to touch up our walls. When he finished, it looked like we had brand-new walls!!! Although it's the same beige color we already had, they look spectacular!!! He did the whole house in about 6hrs."
