Luke and his team rebuilt the wall in less than a day and it looks great (demolition was done by others). I would recommend GCS to anyone.Posted on Google nance ceccarelliTrustindex verifies that the original source of the review is Google. What a fantastic experience we’ve had working with Alex Paulk and GCS. After a significant storm/wind event, this company returned our call within 24 hrs, was on site a day later to assess damages and do a temporary fix to a pole barn building roof. In addition, a plan for a future fix was put in place. The estimate was reasonable, the timeline was within expectations - -but the communication from the company about scheduling was amazing - -setting dates, sending a contract, fitting our project into an earlier opening, arriving when scheduled and finishing a day earlier that expected - -WONDERFUL! We will use Alex and GCS in future projects! HIGHLY recommend.Posted on Google Becky LoomisTrustindex verifies that the original source of the review is Google. We had our house re-side with hardy plank to match our garage. The two man crew were amazing. They worked steadily all day everyday. They did not cut corners and paid attention to detail in every phase of the job. They cautiously ensured that the work was reviewed daily and explained everything they were doing. The bid was reasonable and they even gave us a rebate because some of the work in the estimate was not necessary to complete the project. Imagine that. Rate them a 10. Above and beyond expectations.Posted on Google Lisa HartTrustindex verifies that the original source of the review is Google. GCS Construction completed several projects for us. Over 3000 sq feet of new siding, installed new Milgard Windows and sliders, front porch face-lift and structural work in our kitchen. Alex and his crew are professionals and did exactly what they said and in a timely manor. Rain and all! We highly recommend Luke Vincent and Alex Paulk @ GCS they really helped with updating our home.Posted on Google Woody & Tiffine RichterTrustindex verifies that the original source of the review is Google. Great work by these guys! Fixed a leaky roof and corrected some faulty and shoddy work by previous roofers. And super job of clean up. Haven't found a nail yet!Posted on Google HYL TeamTrustindex verifies that the original source of the review is Google. Alex is amazing!!! What incredible customer service! I had to contract them from a distance. They are trustworthy, reliable and stand by their word. And the roof looks amazing! I highly recommend.Posted on Google Kevin CannonTrustindex verifies that the original source of the review is Google. Had a small roof repair after a home inspection that needed addressed within the month. They answered my call right away and were happy to help, fitting us in their schedule almost instantly. Luke and Alex were super nice and professional both on the phone and in person. Some poorly timed snow storms delayed them a few days but they were great at communicating what their plans were. Highly recommend these guys!Posted on Google SCTrustindex verifies that the original source of the review is Google. GCS went out right away to assess my roof, made the repair and gave ma great price for a new roof. They sent me photos during and upon completion of thr process. I dont live there full time, but my neighbor said they worked fast and furious to get it done. They did my roof during the winter, and completed it before the weather became a burden. Would definitely use them again for other projects I have coming up.Posted on Google Norman chesserTrustindex verifies that the original source of the review is Google. We hired this general contractor for our home renovation, and the results exceeded our expectations. The team was punctual, skilled, and communicated clearly throughout the project. They stayed on schedule and within budget while delivering high-quality workmanship. The entire process was smooth and stress-free. I would confidently recommend them for any construction or remodeling needs.Posted on Google Barbara FrananoTrustindex verifies that the original source of the review is Google. Our barn roof was damaged by a windstorm in December 2025. Our insurance appraiser estimated the cost to replace the damaged panels was less than our deductable so we were responsible out of pocket for the repairs. We contacted GCS, and Alex came out to give us an estimate for the repairs. His bid for parts and labor was less than the insurance estimate. We have also had leaks in other areas of the roof. Alex noticed the origional installers had used screws that were too small. He suggested removing the screws and replacing with the larger proper size and installing aditional screws to spec fastener pattern. They were able to come right away before weather got bad again, and did an outstanding job. We were very impressed by the level of professionalism and ease of interaction. We have no complaints! Thanks!
