Constraction reviews in Littleton, Colorado

GS Exterior Experts just finished replacing the siding on our house. They did a great job. Oswald was our project manager, and he was excellent - took care of all the details, and was a pleasure to deal with. Our onsite crew was led by Wesley (I think!) and they were really hard working, respectful and helpful. The finished result looks good!

John Vigil was great to work with and was very responsive to all my concerns as we were out of town when the install of our James Hardie Siding. We didn't have much to cover, but the job took 3 days total, including removing the old exterior. Everything is sealed and cut to spec. We cannot be happier.

We recently hired GS Exterior Experts for a full-house renovation project, and we are very happy with the results. The team replaced all of our siding with HardiePlank and installed a new metal roof. Both projects were done with high quality results and an attention to detail.

What truly set this experience apart, though, was working with Oswald. From the beginning, he made us feel like we were his only client. On the occasions when something needed follow-up, Oswald came out personally to assess the situation. In some cases, he was able to complete the work himself in the same visit. His responsiveness, professionalism, and hands-on approach gave us confidence throughout the process.

We’re satisfied with the results and would recommend GS Exterior Experts without hesitation.

GS Exteriors made our 100 year old house feel like a new home!! They know what they are doing! Installation of all new windows, plywood, insulation and James Hardie siding in 2+days. 100% professional, quality work. Including nice trim around everything and siding our messy area under the closed in porch. Once they were on the job, they were fully committed to our project. No spreading the crew thin over multiple jobs. Left all neat and looking beautiful! The house is much warmer, quieter, and just cozy. The was our best run and must gratifying house project!!

We went with GS Exteriors for a large scale stone veneer installation project on our home. Manny was a pleasure to work with, and always made sure we were informed, consulted, and happy with the work as it was being done. Despite also simultaneously working as a firefighter, he always responded immediately and thoroughly answered any questions we had along the way. The crew was also very professional, doing high quality work on time and on budget. I can't recommend this company highly enough!

We just had our house re-sided and Ernest, Jaelynn, and Oswald were all amazing! Everyone was super helpful, no pressure, and very responsive to all forms of communication and answered all our questions. The residing crew were also very pleasant to work with and their craftsmanship is impressive. We are super pleased with our house and how it turned out. Definitely recommend them!

They took care of our whole exterior. Siding, trim, soffit, fascia, roof, gutters, and downspouts. We picked them due to Keith’s knowledge and zero pressure sales technique. The computer renderings of our house really helped us decide the colors and design we wanted. The project manager, Oswald, stayed on top of the project and was quick to adjust for any issues or changes we wanted. Jaelynn kept everything organized and transparent with any change orders and invoicing. The crews were hard working and respectful. We love the new exterior of our house!

I cannot stress how helpful just roofs and gutters were while moving! I would absolutely recommend them to any friends and family in the future for roof repairs and replacement. They are so honest and in constant communication !

We had a very large job - Everlog siding, Cedur roof, Rock Garden stone wainscoting on a house, garage and shed, and two large TimberTech decks. There were a lot of moving pieces, and it came together beautifully. The work crews were incredible - talented, showed pride in workmanship, polite, and responsive. Keith from GS was always upfront with costs about changes we wanted to make and was willing to be flexible.
The result is amazing - we can't wait to stay home!!

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.

Had my entire home changed to James Hardie siding with GS Exterior Experts and was incredibly happy with the whole job from initial quotation in 2020 to finally getting the job completed in April 2024. Ernest Lopez was fantastic to work with up to signing with planning and color schemes, and Oswald and his team were fantastic as well during the install. The installers were very detail orientated and that resulted in a finished product that makes the home look great. Would highly recommend them for those interested in Hardie siding.

Keith and his team did an amazing job replacing my siding and installing a whole new deck! They are incredibly fast and efficient! I would recommend them to anyone looking to get some work done around their house. Very happy with how everything turned out!

I had some touch up done for the exterior paint. Oswald was a pleasure to work with. He was responsive and got the job done quickly. The crew leader Wesley's paint job was impeccable. I couldn't detect the overlay of paint.

Littered our neighborhood with your door hangers. My husband and I take pride in our neighborhood and this morning out on our walk, your flyers were carelessly placed. Therefore, they are nothing but litter. We picked up 20+ pieces on the ground and there were countless more we couldn't get to as we didn't want to invade someone's property. Your door hangers are intended for doors and shouldn't have been lazily placed on mailboxes. Placing them on doors would have meant someone would have had to get out of their car and walk to properly place them. If you're going to solicit, please send someone that wants to put in some effort and doesn't assume it's okay to carelessly litter our neighborhood!

I cannot say enough good things about the siding job and crew that re-sided my house. The attention to detail, the quality of workman ship and professionalism of the Wesley crew was outstanding. Oh, and both Geo and Oswald were both excellent as crew chief and project manager. I 100 percent recommended this crew.

Oswald and his crew were friendly and respectful to us and our property. The siding came out beautiful. Keith was very helpful when it came to designing the siding. We already recommended GS to our friends and would definitely consider them for our future projects.

GS Exteriors just finished putting up new James Hardie siding on our house. We had been debating siding color, brick paint color, trim, and all the little things that are hard to visualize, fortunately Ernest Lopez helped us ease through these decisions. He provided us with samples of work for the colors, personal design opinions, and his recommendations. In addition to that Ernest had an incredible crew work on our house led by Luis. Between the two of them our house turned out even better than we ever imagined. I can't say enough about the responsiveness from all the GS team when we were mulling over ideas and then once the work started the team at the house accommodated all our my questions and concerns, even providing me with thorough explanations as to how and why they did certain things. The coordination of all the items was seamless, we even had our front concrete replaced by GS before the siding started and immediately after that siding began, gutters, and then painting of brick, panels, and foundation. Again, everything just flowed so smoothly and the outcome is quite impressive. Thank you GS for the amazing work and a special thanks to Ernest and Luis for handling our home as if it were their own. Hopefully my before and after pics do the work justice.

It was a pleasure to work with Ernest and his team at G.S. exterior experts. They were responsive, professional, and affordable for a new construction siding and roofing project.

I especially appreciate the attention to detail from the color-matching caulking to carefully painting the inside of the soffet trim for an excellent final product. I'd highly recommend them for any roofing and siding needs.

AMAZING. We had GS put on new siding, new paint and they were amazing. Very good communication. Prompt with revising the agreement a few times because we changed it. Siding was done in 4 days. When they finished at the end of the 4th day the dumpster was gone by 7:15am the next day. Painters showed up that day and finished the painting in 2 days!
Very fast, accurate, and priced very fair. WILL use them again when I have the chance. Thank you Keith!

Oswald at GS exteriors came back after the James Hardie siding project was finished, and installed a flood light on an eave. He pays attention to details and truly wants his customers to be happy.
He went above and beyond, especially since we live in a distant rural area.
Fantastic customer service,

We had our whole house siding replaced with James Hardie siding, new OSB plywood, insulation, new shutters, gutters, fascia & soffits. The whole shebang! No mixing old with new. Make it all new! The house looks amazing! It’s literally a brand new house. Oswald, Ernest, Moses, Omar and their team at GS do excellent work! Their attention to detail is impeccable. If there are any issues at all, they will take care of it. Don’t stress, rest assured & have confidence in GS Exteriors to do an excellent job with installation & do it professionally. They will strive to make things exactly how you envisioned to ensure your happiness. My satisfaction was very important to them. They take pride in their work and it shows. The team at GS Exteriors is so skilled and they know what they’re doing. I am getting so many compliments from all the neighbors. You will not be disappointed. You can’t beat their warranty on, not only the material, but their workmanship. 5-Star company all the way!
