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!

  • GS was a great company to work with. I would use them again in a heartbeat.

    Tim K.
  • We had our entire house re-sided with James Hardie siding. Overall, our expectations were either met or exceeded in most areas, including quality of materials and workmanship and timeliness of completion. From start to finish, the entire project took five days. GS was quick to address any questions or issues that were raised to our complete satisfaction.

    Stephanie C.
  • We are very pleased with the siding installation. All work was scheduled to begin within a week of our signed contract and completed in one week. The entire crew was very professional and friendly. We would definitely recommend GS Exterior Experts to anyone needing siding. -

    Maynard L.
  • High quality work, and very professional. The team worked extremely hard to get the job done quickly. They were very responsive and did excellent work. I would highly recommend them to anyone needing siding installed on their house.

    Kirk L.
  • Installing James Hardie fiber cement siding with the Woodstone finish over my old cedar wood siding was the best home improvement project I've ever done and I wish to thank Keith Virgil and his assistants for all their due diligence and help on the project

    Frank P.
  • High quality work at a very competitive price due to low overhead. As with any job the homeowner needs to review all of the work, especially the small details, and communicate with the contractor. They were exceptionally responsive in addressing all of the small items which I identified. All of the items were minor details with nothing major.

    Hank T.
  • From start to finish Ernest was great to work with. The installation crew were very professional. The finished product exceeded our expectations. From our experience we would highly recommend GS Exteriors.

    Michel S.
  • This company did a great job! Everyone I came in contact was extremely professional. I am very happy that they communicated during and at the end ensuring we were satisfied with the job. They installed James Hardie siding and trim and it looks wonderful. Be confident you will be happy with the result and hire this company!

  • After an extensive solicitation and review of exterior contractors we settled on GS Exteriors. Settled isn't the right word as they were substantially below the cost estimates of other companies and their workmanship was top notch. We were originally apprehensive because of the price disparity but after interviewing several clients and scouring reviews we decided to move forward with them. One item to note: The man that answered my phone inquiry, Ernest, was the same guy that came to my house and the same guy that coordinated the various work crews that executed the project. With the other companies I interviewed, it seems as though I was working with a pile of other folks dedicated to making the sale as opposed to guys actually coordinating the work.GS Exteriors replaced my existing original panel siding with James Hardy Hard panel, added a layer of rigid insulation, painted, faced a portion of the front of the house and our chimney with stacked stone, replaced a bank windows, and rebuilt a deck. All of the work was performed exceptionally and in a timely manner in spite of the work being accomplished much later in the season (Fall/Winter) than most companies work. We couldn't be happier and continue to receive compliments from neighbors on how great the house looks. Highly recommend these guys!

  • Ernest was extremely professional and communicated great. All job tasks occurred on schedule and I was impressed with the follow through on the timeline agreed at the start of the project. I am detail-oriented and expected a very high level of quality for the price on this job. I felt the job site was chaotic and should have been kept cleaner. The install crew made several minor errors but all were fixed to my satisfaction - GS was very professional about listening to my feedback and showed a strong commitment to addressing every request I had for correcting minor defects. Four stars because I had to do more work than I wanted to monitor the quality of the install, but the most important thing is that the company was highly responsive and made sure in the end I was completely satisfied. I would definitely recommend GS, and they would be my first choice for a future project.

  • I absolutely will refer GS Exterior Experts and I will absolutely use them again if necessary. Please see full review on Angie's List.

  • Ernest and the gang were very patient, courteous, and concerned for our satisfaction. I would recommend them unconditionally.

    Walt B.
  • GS Exteriors Experts did an amazing job! Keith took the time to explain all the options, the pros, and cons of each and answer all my questions thoroughly. The crew was very professional and their attention to detail was second to none. A total home run

    John C.
  • I highly recommend them. I have already recommended them to neighbors. Everyone has complimented their work.

    Lisa S.
  • Thank you, GS Exteriors, for a beautiful job. As a first contracted project for young new homeowners this was a big thing to tackle! We appreciate Mel helping us through the process. The siding looks beautiful with expert workmanship. It was also great to have a one-stop shop for all the work repairing our house after the hailstorm. The siding, roof, soffits and fascia all look great!

    Jennifer H.
  • I am happy with the quality of the work. The guy I have been working with is committed to seeing the job done right and to my satisfaction which I appreciate. There are always bumps in the road but I am confident that when It is finished that everything will be good.

  • Ernest is a great listener and assigned a super crew. These guys take pride in their work! -Kurt S. We love the new look of our house and was so excited to see the old siding/deck posts/stairs gone. We've received a lot of comments about the work and even though there were some issues we would do it all over again if we had the chance.

    Michael D.
  • We had a large, rather complicated house to repair and GS Exteriors did a wonderful job with everything - the siding, gutters, roof and new garage doors. Ernest Lopez responded quickly and effectively to all my concerns and questions and all the crews involved were competent and courteous. They made a stressful experience much more pleasant and our house is beautiful! Thank you!-

  • First of all, GS Exterior Experts was the overall best of the 4 bids I received for the replacement of my home's siding....appropriately low key, timely, professional, knowledgeable, thorough. Job was started and completed on time.....in the winter. No cost overruns or scope of work issues. There were no other problems or disagreements. I knew going in that James Hardie Siding, although relatively expensive, was the best product for my situation. A good value for the investment’s Exterior Experts business owner Kevin Vigil was my principal point of contact. I believe he owns and operates a very good company. Overall, I am well satisfied with G S Exterior Experts as the contractor on this major home improvement project

    Mike O.
  • We had a fantastic experience from start to finish with GS Exteriors. Our salesperson Ernest was knowledgeable, friendly, accommodating, and patient while we decided on the colors. The installation team was fast and did first rate job. After each day they made sure everything was cleaned up and put away neatly. I will use GS for any future jobs and highly recommend this company

    Christopher S.
  • My husband and I are delighted with our new James Hardie siding. It accomplishes several goals we had: protection against hail damage, low maintenance and a pleasant curb appeal for our home. The team of workers at each step were excellent — very professional. We highly recommend this company. It was a great outcome.

    Lynn D.
  • Yes - we were pleased with the whole project from start to finish.

    Stephen H.
  • Keith Vigil, the owner, was great to deal with and we really appreciated his professionalism. His crew was timely and very efficient in their work. Delivered a great finished product. Very hard-working team. Would recommend without hesitation

    Nancy H.
  • We were very pleased with GS Exteriors from start to finish

    Dan Q.
  • I knew I wanted James Hardie siding and had seen a house in my neighborhood that had that siding installed by G.S. Exterior Experts so I included them when I decided to start quoting the project. I had quotes by 3 companies and G.S. was hands down the winner. The lowest price does not always translate to the best value but in this case G.S. was both. One of the highest quotes, from a company I won't name, wasn't even formally written up. Just scratched out on a yellow legal pad! Everything from the quote to the delivery of materials and the installation was very professionally handled by G.S. Exterior Experts.

    Lawrence C.
  • I recommended GS Exterior Experts already to friends and coworkers, neighbors said our house is the best looking in the neighborhood, the fact that they didn't feel the need to post yard them. (which I would be happy to do) speaks for them.

    Markus K.
  • Every aspect of the dealings with GS Exterior Experts was very positive. From the first meeting with Keith until the job was completed everything was professional and friendly. If I or any of my friends need any work done I will strongly recommend GS Exterior Experts.

    Bob M.
  • My wife and I are extremely pleased with the high-quality workmanship and customer service provided by John Vigil at GS Exterior Experts. We get compliments all the time!

    John B.
  • John Vigil did a great job, as did Tony and the entire crew. Very hard working, skilled and pleasant. Highly recommend! High quality work done in a timely manner; fair price. The crew came to work and they worked hard.

    Lou R.
  • Keith at GS Exteriors was very helpful, professional, and made the whole project easy and seamless. My house looks great! Thank you Keith!

    Joan P.
  • They did a great job!

    Ron S.
  • Mel was a pleasure to work with. He personally made sure that everything on our project went well. We would use them again

    Amy F.
  • Super happy with the project and how everything turned out! Would definitely recommend GS Exteriors to anyone looking to update their home.

    Michelle W.
  • We hired GS exterior to install James Hardie siding. We had five contractor bids and GS Exterior was by far one of the more reasonable priced contractors. We decided to go with Keith because he was extremely prompt with questions and text that we sent. We were also impressed with his bid that he wrote up. It was very detailed and listed out all the prices. During the entire process Keith continued to keep great communication and check in on how the project was going.

    Britany R.
  • We hired GS Exterior Experts to redo the siding on our 50-year-old home. They did a fantastic job and we had zero issues. Keith was an absolute pleasure to work with, and his attention to detail was second to none. He was prompt at addressing all of my questions and concerns throughout the entire process, showed up on time, and got the job done much quicker than I expected! His crew was great too... Very courteous, hard workers. I highly recommend these guys for your exterior home needs.

    Josh G.
  • My wife and I hired GS Exterior to place siding on our house, and overall, I would recommend them. They do good work, they are affordable, and they're surprisingly fast. If you're looking for someone to install Hardie board on your house, I'd definitely call them for an estimate, and wouldn't hesitate at all to hire them again for similar work.

    Jason L.
  • My wife and I could not be happier with the entire experience with GS Exterior Experts. We recently got new siding, windows, and gutters from GS Exterior Experts. GS Exterior Experts were quick, professional, and considerate of our schedules. I will be recommending them to anyone that will listen.

    Ian G.
  • Amazing siders! These guys are literally experts. I can personally vouch for them considering they have resided both mine, and my parents’ home. They used James Hardie Siding, only the best products. Only took them about 5-6 days on each house and our homes are about 2500 square feet! They used to work for James Hardie corporate so you know they are the real deal.

    Keith and Ernest were the guys I spoke with over there and they were really responsive which was really important to me considering the amount of money we invested in our home. Knowledge guys about both installation and products. I'd recommend to anyone!

    Eli M.
  • These guys know their stuff. They weren't the cheapest, but by far not the most expensive bid we got. They did Hardy siding on our house as well as new gutters and changed out some sliding doors for windows, framing in our sunroom. They were always fast, efficient, and very quality work. I HIGHLY recommend them!

    Katie M.
  • John vigil was prompt and professional. He always returned emails or calls. He gave me a very good estimate. In the end I went with another company solely because I got a personal recommendation. GS was my second choice. He made me feel comfortable and wasn't pushy.

    Cam W
  • G&S Exteriors did several types of work for us this summer. Roof replacement, exterior painting, and window replacement. On the roof, they were 5 stars. Crew was fast! And they left the work site immaculate.
    On the ext paint, very good, 5 stars. They did a great job on the caulking. And our job ended up needing more paint than they quoted due to wood condition, and they ate the cost of that.
    Gutters - if I could give 6 stars I would. The installer was ingenious with how he worked with our roof lines, and the gutters look great.
    Windows - 3 stars. There were issues with install and in general the team that installed the windows seemed a little sloppier than the other crews. That being said, the price was a very fair price, and I would use them again, I would just be prepared for delays in the timeline.

    Overall, the highest rating goes to the communication about our jobs. John Vigil, our contact, kept us updated on everything and he was upfront with the problems encountered. We are looking at deck work next spring and I will definitely be calling John & G&S first to quote it.

    Katie B.
  • We hired GS Exterior Experts to replace our roof and gutters after hail damage. They were prompt, responsible, reasonable in their estimate (evidenced by the fact that my insurance company paid promptly and without argument). The materials showed up when expected, as did the crew, and they left my yard looking great. The finished work looks very professional and my house looks better than ever. Thanks guys!

    Mardee B.
  • Hired Keith & GS for a whole home re-side with James Hardie cement board. The original sales pitch was very low pressure. Once we decided to go ahead, Keith was very responsive to multiple questions and e-mails I sent his way. The crew was efficient, completing the project well within the projected time frame. The only minor snafus were that the nail sweeps weren't as frequent as a neat freak like me would like, and it took a little extra back and forth messaging to get some minor issues post-main project taken care of. However, these are fairly minor quibbles. The work itself is of very good quality, and I would definitely hire this company again in future.
