GS Exterior Experts

After recently meeting with four different siding companies, we hired GS Exterior Experts to install James Hardie siding and I couldn’t be happier with our decision. From start to finish, the experience was excellent. The owner and salesperson, Keith Vigil, was outstanding—extremely knowledgeable, patient in answering all my many questions, and always responsive throughout the decision-making process. He really gave us confidence that GS was the right choice. Our project manager, Oswald, brought great energy to the project. He was enthusiastic, quick to answer questions, and kept everything moving smoothly. The entire crew was exceptional as well—they arrived on time every day, worked hard, and left the property neat and clean at the end of each day. Not only were they skilled, but every

We are absolutely thrilled with the new siding installed by GS Exteriors! From the very first consultation, their team was professional, knowledgeable, and transparent about the process and pricing. Their 3D modeling software helped us choose the perfect James Hardie siding style and color for our home, and the entire project was completed exactly on schedule. Armani was available to answer all of our questions about their bid and the way the crew would handle some of the unique aspects of our home including the solar energy box and the dish. We had a couple of minor miscommunications about the location for materials and the dumpster at the start of the job but the project manager, Oswald, was responsive to our concerns and handled them immediately. The crew, led by Wesley and Erlyn, was

I would highly recommend GS Exterior Experts if you’ve decided to go with Hardie Board siding. They transformed our home exactly the way we envisioned and discussed before the project began. Jaelynn and their siding and painting crews are top-notch and professional throughout the entire process. I would give more than five stars if I could!

In August 2025, GS Exterior Experts replaced the vinyl siding on our Boulder house with James Hardie siding, along with soffits, gutters and several windows. Working with GS Exterior Experts and their Project Manager Oswald Hernandez was a very pleasant experience for us. We can recommend this company for their high-quality work and their excellent interaction with their customers. All team members worked extremely hard, were well organized, communicated well with us throughout the entire project, and stayed on schedule. We are very happy with GS Exterior Experts' workmanship and will definitely consider them for future exterior projects on our house.

We had them install beautiful James Hardie siding on our mountain home. From John, owners initial quote and time to Oswald and Jaime managing the project and crew, I couldn't be more impressed. We had them install the color siding but trim didn't have colors we liked so we painted ourselves. They made sure it was all delivered for only the items to paint and second delivery for stuff to install closer to project start. The crew attended to every detail including some weird areas with an addition we did to the house. They are truly experts of this product, made sure things are sealed up properly, manually hand painted all touch up areas and even painted the cut end of the trim we painted. We fully expected to have to do the touch up ourself. They were all very kind and did a great job clean
