I highly recommend this company. This days is hard to find real people when dealing with companies. Guillermo did my tiles and flat roof. My first concern was to get a company that was licensed but then of course getting the same company that gave me a good price and guaranteed they're work. 21 did both and I have to say the way they treat they're customers is just something else. I was given a contract guaranteeing the work, I was explained step by step the process of the work being done and they were more than open to any suggestions. I'm very satisfied with they're work.
I want to start by saying that rarely nowadays you find a contractor who would answer your calls once they get the downpayment and Guillermo always do. 21 Construction is company I would recommend for all your roofing/ remodeling needs, I can't say nothing but good things about Guillermo and his crew, they are very professional, crystal clear explanation of the job and he will go far and beyond to please his customers. Keep up the good work and I would keep recommending you. Thanks.
I am so happy with all the work that 21 Construction Group did at my house and removing the old roof and replacing it entirely for an unbeatable price and quality. I absolutely loved the final result. I would highly recommend them to do any work related to your roof, you will have all the guidance and advise from Guillermo that you need with a high level of professionalism.
William is one of the most responsive and communicative contractors I have ever worked with. He answered all my questions and was personally engaged in our roof replacement throughout the process. Other contractors only show up when it’s time to get paid. Not him. He guided the project every step of the way.
First off let me start off by saying the owner Mr. Diaz is the ultimate professional. He is very involved and hands on with all of his projects. Always on time and shows up to double check work and to assure you are SATISFIED. I highly recommend 21 construction. Competitive pricing and fast service.
