Siding Contractor reviews across the US

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!
FYI this was a custom color order from their Magnolia collection.
Color: Birch Tree
Trim: Iron Gray

Great work! I had GS do new Hardie Plank siding, as well as painting brick, doing new gutters, and replacing an exterior sliding glass door. The whole project was done within a week of starting, and I'm so happy with how everything turned out. Keith is great to work with, very responsive and able to adjust the job as my needs evolved.

We are so glad we chose GS Exterior Experts to do our siding project! Everything Keith told us during the sales process about what to expect and the quality of work that would be done was absolutely true. Oswald Hernandez was our project manager and his crew including Omar and Moses (I didn't know the rest of the crews names but there were 8 total) were above and beyond superior. They took the old siding off and found our home never had a plywood base so they quickly put new OSB boarding up and had all the new siding completed in 3 days. Antonio Bermudez paint crew were up next and did a fantastic job painting. Then last but not least Luis and his crew completed our gutters and they look awesome. I would not hesitate to recommend GS Exterior Experts to anyone. Although this was an expensive project, the price we paid was definitely competitive with our other bids.

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.

Friendly, very competent, professional, efficient and reasonably priced. They made sure we were completely satisfied with their work. GS Exteriors was recommended to us from two neighbors up here who also used them to re-side their homes with Hardie Board up here in the mountains and were similarly impressed. Recommended.

We would like to thank all the GS Exteriors staff for the great work they did on our 1904 farmhouse. Due to the age and condition of the existing siding/trim the crews had their work cut out for them. Special thanks to Noah, Oswald, Jaime and all of his crew and painters to create the vision we have always had for our house. As the James Hardie ad says: “We have fallen in love with our house again.”

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!

We had our exterior vinyl siding replaced with James Hardie siding along with soffits, fascia, shutters, gutters and trim painting. The entire process from the initial estimate to final cleanup went extremely smoothly and the workmanship was flawless. The crews and project manager Oswald were completely responsive to our questions and made some minor changes without any need for change orders. We are delighted with the project and our home, which looks better than new. The photo shows a sample of their work.

The quality of work done by GS Exteriors is totally phenomenal and I strongly recommend you seek out their services.

The reason I had the work done was because as you could see from some of the before pictures of my home, my siding was melting.

My awesome-wonderful neighbors (they are angels!) like to have their blinds up which causes a magnifying glass effect which melted my vinyl siding. There's no way folks shouldn't be able to have their windows open for the sunlight, but those low E windows cause amazing damage when the homes are so close together. If you drive around Green Valley Ranch, you will see this proof throughout the neighborhood and of course because the material is so cheap, the homebuilder uses it. Given my issues, I knew something had to be done as the vinyl and replacement vinyl siding were melting horribly and I did not want water damage and even worse, mold.

I reached out to GS Exteriors given all of the positive results via Google, but also many other websites that confirmed their quality workmanship. When meeting with Ernest our one on one was laid back and chill. It was so easy to go through all of the project planning and I ended up going with the installation of James Hardie siding given its durability and superb reputation.

Delivery of the materials was done on time with excellent quality supplies provided. Oswald was (is - you'll see) my Project Manager and he personally made my home residing project exponentially easier. From the time of tear down to reconstruction, the project lasted less than two (2) full weeks. The crew was just top notch, they cared about question I asked and they made sure I was comfortable throughout the entire ordeal. The cheap vinyl siding came off with ease and the cheap Oakwood Homes house wrap was like a paper towel - it just ripped apart with no effort. I am a fan of James Hardie siding and as you can see, it looks amazing.

Now, onto the storm most Denverites won't forget, 05.30.2024. Many homes throughout my community that have vinyl siding had damage to say the least but my James Hardie siding withstood the brunt of the worst storm since 2014 and without a scratch!

Thank you to the crew, project manager and owner. I could have done without the devastating storm but I feel so much better that I have GS Exteriors as they have my back and will not only restore my home, but just make it better (and my parents too).

I love my new roof! The entire process was smooth and fast, thanks especially to Jacob, who walked me through every step and made sure all my questions were answered. He also knows all the best gyro places in the city. The crew was professional, efficient, and did excellent work. Highly recommend this company!

GS Exterior Experts were great from start to finish. We found them through our neighbor as we saw how quick and professional they were doing their siding project.
GS Exterior Experts are very responsive and had a good competitive price. We had whole house siding, new window, new entry door, and new roof due to hail damage. The various separate crews used for the roof, siding, gutters, entry door and windows, were fast, efficient, knowledgeable, and cleaned up every day. We are very happy with everything, especially the look of the James Hardie fiber cement siding.
Oswald, the lead coordinator for our project was great to work with. We recommend using GS Exterior Experts.
