    I had a fantastic experience with Window World from start to finish! Mike Cook, our salesperson, was outstanding—professional, knowledgeable, friendly, and easy to work with. He made the entire process simple and stress-free.<br><br>Jesus, our installer, was equally impressive! He was professional, courteous, and clearly takes pride in his work. The installation went smoothly, and his attention to detail was excellent.

  • Andrew Seidman1.0

    3 window seals have broken in seven years since the windows were originally installed. I am not the original owner, so the fine print states they can't help me since the warranty follows the purchaser, not the windows. While I understand they can enforce that ridiculous warranty policy, 3 broken seals in a short period of time should serve as a warning for everyone else to stay away from these windows. The representatives I spoke to regarding the issues were rude and unhelpful. Avoid at all costs.<br><br>EDIT: Window World's response is just a reiteration of their policy that they don't stand behind their windows. I accept that I'm not qualified, but I maintain my warning to avoid these low quality windows that will fail in a short time.

    Window World did a great job all the way through replacing my window. From the straight-forward estimation process, without the heavy sales pitch or buy today scenario. The installer was great, showed up on time and efficiently moved through the installation. He had a great attention to detail for each window and was clean and super nice. I recommend Window World to anyone who doesn't want to pay over three times the price for basically the same windows.

    I highly recommend Window World of Denver. I recently had a garden window installed, and the entire experience was seamless from start to finish.<br><br>My Sales Specialist, Mike Cook, was exceptionally knowledgeable, informative, and personable. He identified the exact product for my needs and guided me through the process step-by-step. The installation team, led by Jesus, was equally outstanding. They arrived punctually, clearly explained the installation plan, and executed the job with great attention to detail. In addition to being courteous and professional, they left the work area immaculate.<br><br>The final result exceeded my expectations. Thank you to the entire team at Window World for such a fantastic experience!

Company Background

About Window World of Denver

Window World of Denver is a locally owned franchise of the national Window World brand. According to its website, it has served the Greater Denver area since 2003 and has installed more than 150,000 windows over the past 15-plus years. The business operates from a production facility on East 76th Avenue in the Denver 80229 zip code, where its crews and warehouse are based.

The product list is broad for a vinyl-focused company. It includes double hung, 2-lite and 3-lite sliding, casement, bay and bow, awning, garden and custom shaped windows, along with entry doors, patio doors, French rail patio doors and French doors. The site features a production manager, Scott, who describes more than 20 years in construction, including roofing, siding and window replacement. The company also lists a limited lifetime transferable warranty on its basic windows, financing options with an open line of credit, and a free estimate process.

The accreditation page cites Energy Star partnership, a Good Housekeeping seal, a Better Business Bureau accreditation and a ranking among the nation's largest remodeling companies. These are claims the company makes on its own site. Google shows 4.6 stars from 520 reviews, read November 3, 2026, tied for the lowest score among the companies on this list, though still above our 4.5 minimum. The office keeps weekday hours only, closing early on Friday.

Window World of Denver suits homeowners who want a lower-priced vinyl window with a warranty backed by a national brand and a financing option. It suits people less well who want premium wood or fiberglass lines, or a boutique experience, since the model is built around standardized products. Before booking, ask for a written quote showing the model, glass package and installation labor for each opening, ask who will install the windows and whether they are Window World employees or subcontractors, and read the full warranty before you sign. Colorado has no state licence for window installers, so licensing is handled by cities. Ask whether the company is registered with the City and County of Denver.
