We had our hail damaged, faded, warped vinyl siding replaced with new James Hardie siding, trim, fascia and soffit. Ernest is very straightforward and answered my questions quickly and patiently. The team doing the work were respectful, on time and fantastic. I am very particular and any small or large issue I had was addressed or corrected without hesitation. Not only did GS Exteriors have the best price but also the best service.
I would definitely recommend them (and I met with a lot of contractors/siding companies). Thank you Ernest, Dennis, Marvin, Moses and the rest of the crew for your hard work. Our home looks beautiful!

GS Exteriors were fantastic! I was recommended to talk to Ernest for new Hardy siding by a neighbor as they had done an amazing job for her. I shopped around a little bit at first but after the quote and the trust Ernest instilled in us we decided to go with GS Exteriors. Ernest to Dennis to the entire crew were fabulous and FAST. These guys worked when it was freezing but they put siding on a 3500 sqft home in a total of seven days!
To be honest one of the reasons we chose this company was the fact we were told they work fast. Ernest wasn't kidding! Everyone was SO friendly and genuinely seem to enjoy what they do and boy, do they work hard! Even though they were quick the quality of their work was incredible. They took care of everything and the quote even included the two massive dumpsters they needed for this job. They cleaned up before they left everyday too. I can't say enough about these guys. Seriously, don't bother searching anywhere else. Thanks to all of you at GS Exteriors. We feel like we have a brand new luxury home now!

We used GS Exterior Experts to replace our siding and gutters on our home with James Hardie siding. Keith was awesome to work with and answered all of our questions right away. He addressed all of our concerns and made the whole process easy and stress free! The crew showed up early each morning and was friendly and professional. They're workmanship was exceptional! The whole job took 4 days and I couldn't be happier with the results. I would highly recommend GS Exterior Exports if you're considering any siding work on your home!

Keith and the entire team at GS Exteriors were phenomenal! I was in need of new siding, windows and gutters and they were the one stop shop to do it all - and they did a great job. The team showed up first thing in the morning and worked all day, completely different from previous experiences with other companies, they got the job done, and did it well. They were friendly, courteous and professional. I would highly recommend using them for your home needs!

This company is amazing. After a hail storm, I was working with another contractor, but everyone in my neighborhood was using GS. I asked for a bid from Keith for siding and gutters and it came in less than what they were quoting me. We switched and they got right on it. The work was done quickly and they are very responsive. We are very pleased with how our house looks. I also got a window quote from them and that will be done later this Spring. I highly recommend GS Exterior Experts!

The GS Exterior people and service were great! John Vigil in particular was fantastic. We had our whole home siding, trim, fascia, and soffits replaced with James Hardie Fiber Cement board. They worked with our insurance company to help get the siding replacement covered per our policy, which took some work. The work itself was fast and quality. It was easy to communicate with them through the process and they were responsive to our requests on timing, aesthetics, materials, etc. I would--and have--recommended them to friends and neighbors!
