 Trustindex verifies that the original source of the review is Google. One Stop did an incredible job. We met with Brent Hooper and Buddy Chubb.  They answered every question thoroughly and provided incredible shingle options. All the materials they use are high quality. The crew was amazing.  They gave attention to detail.  They replaced a lot of the lumber under the shingles on the house and the lumber on the back porch roof. One Stop also replaced the back porch roof as well. They resurfaced the chimney. Shane Holman came out to meet with us before work began.  He answered every question. Shane  supervised the work.   He followed up after the work was completed. Shane is very dedicated. I highly recommend One Stop Remolding. Thank You for your quality work.

 Trustindex verifies that the original source of the review is Google. We went with one stop because they were supposed to be able to do any remodeling job. We had roof and entire inside remodeled. Was supposed to take 6 weeks. It took 3 mos. Would have been longer had we not started moving in to get them to hurry up. We were told their beat crew was going to be there everyday to do the job. I used to show up random times during day to see what progress was. Either 1 or two guys there if any.  We found empty beer cans and was told we didn't see them drinking so they werent. They did a walk through and we marked all things needed redone. The first time the contractor came out he litterally walked through took the tape down then left. We did it again. This time they found things that we didnt even see. And was told that crew is done working here. Brought up issue with texture on walls. Was told we only charged you for a grade 2 sanding job and that would need a grade 3 job that we could pay exxtra to get done. The one thing they did fix was cabinet door that the screws were stripping out of. Anything else they wont fix. They dont answer back when my wife calls and they really dont care. They got their money. So now what are we gonna do about a 3 yr warranty that they wont come out for. Was told when we see anything wrong call and they’d fix. Lies. Buddys a good salesman but their workmanship is sub par. Wish we had done more homework on who to hire to do this big a job. We will not recommend to anyone.

Always available and prompt. My new windows are beautiful. They also repaired a cracked brick which was causing a leak at no charge.

 Trustindex verifies that the original source of the review is Google. I reached out to Onestop for a Catio project, and Chris E. was fantastic to work with. He took the time to understand my vision, carefully drawing out the design to ensure it met both my expectations and budget. He was upfront about the fact that they had never built a catio before but reassured me that I would be happy with the final result. The foreman, Angel, was also a pleasure to work with. He was genuinely excited about the project and even shared that he’s a fellow cat lover. He collaborated closely with Chris and me, making sure the interior design included plenty of spaces for the cats to run and lounge. Overall, it was a good experience and I’m very pleased with the outcome.
