Get matched with top siding pros in Mount Hamilton, CA

"Stupendous exterior house painting. Adam met with me, put up my 3 final color selections, so I could see exactly how the finished project would look. GZL exceeded my expectations by close attention to detail with primer & two coats, filling all crevices, painted my front & garage doors, as requested. Stayed on schedule, on budget, cleaned up work area, & did not accept payment until I fully inspected the job to my satisfaction. I'm still so stoked by their work, I trust to reccommend them to my friends & family. GZL pricing can't be beat, for the quality & detail of workmanship. Other offers were absurd by comparison. I feel excited about my "new" looking house! Thank you, GZL!"

"Roman and his team were excellent. Our neighbors had a general contractor do their siding. We have the same painter and he was amazed at the difference in the quality of the work on my house. I explained that RK is a siding expert and it shows. I am so happy with the results."

"Very professional company and very clean. Work is top notch and I would recommend them to anyone I come in contact with. Great job"

"New Gen Exteriors removed the old vynl siding on my house and then installed new Hardie board siding with foam insulation underneath. Serg the owner was very polite, straight forward and easy to deal with, as were his men. They cleaned up each night and were also quiet when they worked, no loud radios etc. I plan on using Serg in the near future, because he does very professional work."

"they did a wonderful job...quick and clean. I would use them again if needed."

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

"Great father son team. Always on time. Matched texture perfectly in house. They took great care with making sure everything was ok."

"I recently had my AC repaired by this construction company, and I could not be happier with the service! The team was professional, efficient, and completed the job quickly.
