I'm glad we decided to hire these guys, as I plan on using them again for many other remodeling projects I have coming up... a AAA+ X 10 + 10 in my book, THANX GUYS read more

When we decided to have our basement completely remodeled, we needed to find someone trustworthy and honest. My friend had previous experience with this company so we decided to have them give us an estimate. I hired Filip, George and their crew not just because the price was reasonable but we were able to get some ideas from his many years of experience in business. They were always on time, working long days, making sure job site was always clean and safe. Filip supplied building materials and we were in charge of fixtures, When we needed him to help us get larger pieces, he offered to pick them up from the stores himself. Now we are able to enjoy what once used to be a storage for entertaining family and friends. Very pleased with outcome and would recommend to all. read more

my first floor apartment has hardwood flooring... when the tenants left, the floor was so damaged that I wanted new carpet installed. I called several carpet companies and it was so expensive even with their deals. I decided to call Filip and asked if it was the best way to go. He came after his work and inspected the place and explained what was needed and saved me a lot of money by using the same flooring that I have. He called his crew and sanded and varnished my floors and even fixed some minor problems with water damage in the ceiling. When it was done, I was very satisfied with their work. Definitely recommend. read more

I hired C02 construction to hang new light fixtures and install a new electrical outlet where there was not one already. I always have reservations about price then about quality. They exceeded my expectations regarding price and overall quality. They were neat, clean and meticulous to detail. The even rewired some electrical boxes that were left overs from a bad do it yourself job from the previous owner. No charge for that. They were clean and on time everyday. Very important for me due to my busy schedule. When they left they didn't left one piece of dirt or dust behind. I will hire them again. Jimmy P read more
