"Overall a great experience with this company. Won’t really know how the repair holds up until it rains again but I would expect no issues. I would recommend."
"Recently we have had a BRYANT AC unit installed with them. Called for a quote on a weekend and loved their customer service. Carlos had a payment plan, installation date and kept us updated on every single question or concern. Everything was installed efficiently, professionally and with care. David and Carlos were both amazing in what they do and even left several ways to contact them for any question, comment or problem that may arise ! A new highly advanced smart thermostat was installed along with new ducts that were very much needed. Goodbye 23+ years old AC and hello to this new AC !! Thank you to everyone working at Grand-mark Service Company ! Keep up the amazing work !"
"Had the pleasure of talking to McKay. Him and his team went above and beyond. I had a few dry rots on my fascia.Time was of the essence and he was able to accommodate and was able to complete the work the next day. 1000% would recommend these guys for all your roofing needs. Called a few places and Grandmark was by far the best priced around."
