🛡 CSLB #1030917 · The Grandmark Team They replaced our tile roof and the ducts at the same time. Didn’t know that was even possible. House is cooler than it’s been in years and I have video proof of every step. The roofing team was kind, clean and professional!
Had the same leak fixed twice by two other Fresno roofers. Grandmark found the real source on video — it was the flashing nobody had checked. One repair. No more leaks.
Three companies gave me quotes without even looking at the system. Grandmark ran a diagnostic and found the real issue. Saved me over $2,000 and my AC has been perfect ever since.
Storm hit on a Friday. Grandmark was there same day — documented everything on video for my insurance claim and had it tarped and repaired before the weekend was over.
All the workers with Grandmark were very professional. They worked fast but got the job done correctly. Geraldo was especially helpful with information and timely work completion. I would recommend them for anyone that needs HVAC repair.
Grandmark did such a great job walking us through the damages and didn’t pressure us into making a decision right away. The inspection included pictures and videos which made the decision easier. The roofing team was kind, clean and professional!
They came out on a rainy Christmas Eve morning within an hour of calling. Technician was very thorough and professional. Highly recommend.
