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

FREQUENTLY ASKED QUESTIONS

Denver’s climate is harder on windows than most homeowners expect. You’re dealing with 300+ days of sun and high UV exposure at altitude, temperature swings of 40–50°F in a single day, occasional hail, and very low humidity that can cause wood frames to crack and seals to fail prematurely. We recommend triple-pane or high-quality double-pane windows with Low-E glass coatings and argon or krypton gas fills. These handle Denver’s thermal cycling far better than builder-grade options. We’ll walk you through the right specs for your home during your free in-home consultation.

Yes, and the savings tend to be meaningful here because of our extreme seasonal swings. Older single-pane or degraded double-pane windows are a major source of heat loss in winter and solar heat gain in summer. Homeowners who replace them with energy-efficient windows typically see 15–25% reductions in heating and cooling costs. We can show you the energy ratings on every window we carry so you know exactly what you’re getting.

Hail damage to windows is common in the Denver metro. If you had a major storm come through, there’s a good chance your glass, frames, or seals took a hit even if it’s not obvious from the inside. We work with homeowners navigating insurance claims regularly and can document the damage during your consultation. Whether your insurer covers it fully, partially, or not at all, we’ll give you honest guidance and a transparent quote so you know where you stand before committing to anything.

Most Denver homes are completed in one to three days, depending on the number of windows and any trim or finishing work involved. You don’t need to hover, our crews work efficiently and communicate clearly about what’s happening and when. We protect your interior, remove and haul away your old windows, and do a full walkthrough with you before we leave. If something comes up that requires a decision, we’ll contact you directly rather than guess.

We install Pella, Andersen, and Marvin – three brands with strong track records in cold-climate performance and long-term durability. Brand matters because the warranty, the quality of the insulated glass unit, and the hardware all vary significantly across the market. Some lower-cost brands look comparable on paper but use thinner glass packages or cheaper spacers that fail sooner in Denver’s dry air. We’ll show you samples and walk through what differentiates them at your consultation, so you can make the call based on your budget and how long you plan to stay in the home.

Yes! Kraftwork Design is fully licensed and insured in Colorado. Whether your project requires a permit depends on the scope of work. We handle the permit process when it’s needed, so you won’t have to navigate that yourself. We’ve been working in Denver neighborhoods since 2007, so we know what the city requires and how to keep your project moving without delays.
