I waited a full year to write this review so that it could be as complete as possible. The sales experience: Excellent. James was great to work with and went above and beyond to meet me at a showroom where I could have a better look at the windows than the small sample. The quote was more than competitive and it was a straightforward interaction without the sales tactics I saw from other companies. The installation: Very smooth. The crew was experienced, worked well together and efficiently and did an excellent job with no residual issues. The windows: I love them. I have lived with them (Simonton windows) for a year and they are beautiful, work well, and are easy to clean. My husband has been tracking our energy usage and our natural gas bills were significantly reduced last winter after replacing with these windows.

Very impressed by the work of Kraftwork Design on a recent siding job in E Denver. I was in need of a contractor I could trust to do the job right while I was not in town, and James definitely fit the bill. He made sure the job was done to standard, and communicated with me any decision points along the way. Very easy to work with, and very professional results. Highly recommend!

I’ve worked with James in the past and been completely satisfied with the massive exterior restoration project he completed for us to repair hail damage, from the roof, windows, siding, painting, gutters, etc. The excellent customer service continues, as he came right out to inspect the source of some water in a can light that we recently discovered. Not associated at all with past workmanship, he quickly assessed the situation and gave his recommendation on how to fix it, turns out we probably need an attic fan. I’m definitely a “fan” of Kraftworks and especially James for his dedication to his customers. Thank you!

Just had our roof (house & garage) replaced for hail damage from the May 2024 hail storm, and I can't say enough good things about the experience working with Kraftwork Design for the roof replacement. After having our insurance company come out and inspect it for hail damage, I contacted Kraftwork Design, and James, the owner came out and looked at our project, and got it going the next week. The entire replacement of both roofs took 2 days, and his roof crew did an excellent job. They were fast, respectful of our property and our neighbors, and cleaned up everything. We also have a glass greenhouse attached to the back of our house, and I was worried about it being damaged, but the roofers took the time to cover it, so it was protected throughout the process. They even covered our roses and bushes so that they didn't get damaged. The roof now looks better than when we bought the house. Now, we just need to paint and restore this house to its original historic charm. If you had hail damage and are looking for an awesome roofer, you have to call Kraftwork Design

James was always in good communication as to when things were going to happen. Smooth project from start to finish. The crews that he used were very professional. Would use again.
