  We were in need of a roof and called GrandMark to get estimate. From the time we called everyone has been so professional and friendly. Carlos came out and gave us a detailed on site estimate with clear pricing and explanations. We signed on the spot and today they are already starting paperwork and checking the site. Im so grateful to have a company that didn’t take the check then not communicate or show up for days. They start the job Monday we couldn’t be happier.

  Nothing but a positive experience with Grandmark roofing. I made a phone call and was clueless and stressed about a leak I discovered. McKay came out the next day and gave a thorough look and quoted us. Following the quote we scheduled and had abad and co worker out the next day and finished the cracked tiles they found. I appreciate the honesty and quick response. This company is awesome and I will be using them for all future needs! Thank you so much!

  I had a great experience with Grandmark HVAC. Their team was professional, punctual, and knowledgeable from start to finish. The quality of the work was excellent, and they took the time to explain everything clearly and make sure the system was running properly before they left. A special thank you to Aramis, the service technician, for providing outstanding customer service. He was friendly, honest, and extremely thorough in diagnosing and fixing the issue. His attention to detail and professionalism really stood out, and he made the entire process stress-free. I highly recommend Grandmark HVAC to anyone looking for reliable, high-quality HVAC service. If you have the opportunity, ask for Aramis—you’ll be in great hands!
