Don’t just take our word for it! Find out what our customers have to say about their experience with GS Exterior Experts.
We had a fantastic experience from start to finish with GS Exterior Experts. We met John Vigil at the Denver spring home show and were immediately impressed. Now that the siding project is complete, we are thrilled with the results! We have received so many compliments from our neighbors! The installation crew was top-notch – attentive and detail-oriented. Oswald and Jaime (project leads) were terrific and a pleasure to work with! We are so happy we hired GS, and so happy with how everything turned out. Thanks GS!

After a terrible hail storm tore through our vinyl siding, we contacted Mr. Ernest Lopez and he walked us through the process of replacing our siding and gutters, from creating color harmony between the siding, the trim and the shutters to insulating the home with a protective barrier. This is an amazing company, under the supervision of their Project Manager, Mr. Oswald Hernández, my home’s exterior was covered in James Hardie siding. This project was completed a little over a year ago, and I have since been exceptionally impressed with their customer service and attention to detail. I have enthusiastically recommended them to family and friends, including neighbors who stopped by and asked about our great looking siding. Any issues and or concerns were always addressed by Mr. Hernandez within 1 to 2 business days with personal courtesy and professionalism.

In November of 2024 we hired GS Exterior experts to replace siding facia and soffits. They did an amazing job. We had a couple exterior doors being replaced (by another company) and John agreed to send someone out to re-trim the new doors after they were installed. It took 8 moths for the new door install to wrap up. John was true to his word and sent out a trim guy to finish trimming the new doors even though the contract had been settled.for many months. Our 40 year old house looks new. We are very pleased with the James Hardie product.
John and his team are amazing. Very professional and easy to work with. No high pressure sales pitch from this company. As for the install process, I can’t say enough good things about Jamie, the install crew manager. He took care of everything. He and the crew were true craftsman.
Having the house reskinned was a big decision for us. GS Exterior experts made the process smooth and painless. Highly recommend this company.

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 couldn’t be happier with GS Exterior Experts! They breathed new life into our 1970s mountain home, replacing its 50-year-old cedar siding with a beautiful new exterior. The attention to detail from every single crew was exceptional. Oswald, our crew leader, was instrumental in ensuring a quality job was done promptly. We strongly recommend GS Exterior Experts for all your exterior renovation needs, including siding, windows, doors, and gutters.

Ernest and Oswald were great to work with. We initially reached out in 2020 about a siding project, and each year Ernest would send one quick check-in with updated prices (if we wanted them), but never once hounded us unlike some other companies we got quotes from. Once we finally reached out to let him know we were ready to go, they were very prompt and within 3-4 weeks they got started. The job was finished in less than a week for a three story home, and our house now looks incredible and bird-free! (Goodbye nuthatches, northern flickers, and tree swallows.) The team was professional and friendly while on site. They cleaned up everything on the last day leaving our deck, patio, and yard looking better than when they started. Best of all, you cannot beat their price. If you’re skeptical because their quote is lower than anyone else, don’t be. Sometimes a good thing is actually a good thing, and GS Exterior Experts is a good thing! We’ll be reaching out to them for all of our home exterior projects moving forward!

GS Exteriors just completed our siding, and we couldn’t be happier with the results! I highly recommend them without hesitation. Their craftsmanship is impeccable. After researching and getting multiple quotes, we found that they offered the best price along with exceptional quality. The team was responsive, easy to communicate with, organized, clean, and professional throughout the entire process.
We worked with Manny, Oswald, Sandra, Javier, and several others—apologies for not naming everyone, as each team member worked incredibly hard. We’re very grateful for the beautiful outcome!

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 cleaning up throughout the day and after each day, even in our heavy winds in the mountains. We had multiple quotes to compare and these guys we in line with the rest but their service heavily exceeded my expectations, which are all the items you can’t put on the quote.

I had a very large project including siding replacement on my home to all the outbuildings requiring the tin replacement. Every crew was excellent to work with. The house project was lead by Ever and his team, the tin was a joint effort lead by Wesley and Luis team. The overall project manager was Oswald who was excellent in communicating the materials and the crews arrival. I’ve received so many compliments on the improvements it’s unbelievable. People say it doesn’t even look like the same property. I would definitely recommend this company for your next project.

Keith and his team at GS Exterior Experts were great to work with. We were recommended to them by a neighbor and couldn’t be happier with how our new siding and roof turned out. Keith was patient and walked us through all our options, and he even worked directly with our insurance to make sure we got the maximum possible benefit. We even hired his team again to do a small job on our back patio and were again very pleased with the results. Keith’s team is courteous, punctual, and clean.. would highly recommend GS Exterior Experts!
