5.0 Chrissy B. Evergreen, CO

Ernest, Steve, and Omar went above and beyond to make our project a success! I'm so grateful for their patience and collaborative spirit as my family resided our remote, 100+ year old family cabin. The cabin looks wonderful now!

5.0 J. Dalton Google Review

We recently had the pleasure of working with Keith with GS Exterior Experts for a whole-house siding and window replacement project.  We went with James Hardie siding and Marvin windows/doors and the design consultation helped tie it all together.  We are very happy with the craftsmanship and final product, to include the new seamless gutters.  We found Keith's pricing to be very competitive and he was very professional and communicative throughout the entire process.

Response from Company:

Hi, J.. Thank you for your review. Glad to hear you had a great experience and wish you and your family enjoy your new siding and windows for years to come! Best, Keith Vigil

5.0 Jim Donald Google Review

GS Exterior Experts replaced the siding and trim with James Hardie products on my rental house. Keith was very responsive with a quote, answering questions and setting an installation date. His team of installers were fast and did a great job with the OSB sheathing where needed, vapor barrier, siding, trim and all of the caulking. The exterior looks brand new!

Response from Company:

Thank you for your business Jim. I'm glad your satisfied with the outcome! Best, Keith

5.0 Jennifer And Chad Roddy Google Review

We had Hardie Siding, Marvin Windows and New Gutters installed on our house by Keith Vigil and his crews at GS Exterior Experts. The crews that Keith has working for him do first class work. Very professional, on time to the job site, very efficient at their craft. More than happy to recommend them for any project that you could want done. Looking forward to working with them on the next project in the future. Sincerely, Chad and Jen Roddy

5.0 Mike Benner Google Review

GS Experts did an amazing job on the hardi and stone exterior. From the initial design consultation they were very accommodating for our changes and additional work added. Their employees were hard working and stayed late to ensure our home was completed on time. Our home looks night and day different and we get so many complements on it. Would highly recommend GS Experts!

5.0 Theresa H. Louisville, CO

Ernest, Luis and crew were fantastic! Their bid came in the lowest, which initially gave us pause, but we are SO glad that we chose them because they were willing to do things for our project that other companies were unwilling to do (i.e., put Lap siding behind the circuit breaker box, etc.).They were at our house on time every day, they worked hard all day long (with only a well-earned break for lunch), and they functioned fluidly and effectively as a team. Their craftsmanship was very high quality, having made custom vents, and their attention to detail was superior! They were very respectful to us (honoring our specific requests for use of masks) and our property. In fact, we felt so comfortable having them on our property that we let them have access to our garage. They completed the project faster than any other company said it could be done, even with a day's delay for house wrap inspection (plan ahead for this - they move FAST!). We highly recommend GS Exterior Experts!

5.0 Rich A. Fort Collins, CO

Keith worked with me for about 3 months before I decided the final project. Keith was very professional and patient. He gave 3 estimates for which to choose from. He even hired a designer to help with the colors and placement of the panels. Work was started on time and it looks wonderful. I would highly recommend GS Exterior Experts.

5.0 Shana B. Wheat Ridge, CO

They did a wonderful job and I pleased with everything they did.

5.0 Barb V. Parker, CO

If I could give this company more than five stars , I would! Keith was amazing to work with throughout the entire process. He communicated clearly about the schedule and the details of the work The crew was quick and completed our entire house exterior in a week I love the James Hardy siding. Our house looks amazing!
