"RJ did an excellent job adjusting our front entry door and storm door. The house had heaved over the years and the doors were hard to open and close. We thought about getting new doors from a big box, but then we found RJ at On Demand 24/7. Now are old doors work great! Thanks RJ!"

"We recently had a new door installed by Michael, and we couldn’t be happier with how it turned out! Our old door was outdated, had a terrible draft, and our screen door would never stay open properly. Now our new door looks absolutely beautiful, keeps the cold air out, and functions perfectly. Michael truly went above and beyond, even paying attention to the little details that made such a big difference. You can tell he really cares about the quality of his work and his customers. Highly recommend if you’re looking for someone reliable, professional, and who takes pride in what they do!"

"Juan helped me with a few projects I needed help with around the house, including installing a dimmer switch, replacing trim around a door, and painting some baseboards. Juan was very professional and courteous, and all of the work was done quickly and everything turned out great!"

"I want to thank Jacob Tryon for selling me my Provia windows and sliding glass door. I want to thank the crew that installed them: Lorenzo, Ernesto, Pablo, Jonathan and Edgar. The crew removed and replaced 9 windows and a sliding glass door in 1 day! I also want to thank the 2 gentlemen that came and replaced the stucco, painting and replacing of my bars on my home. All the way through the whole process I was pleased with the professionalism. Everyone answered all my questions along the way. My Provia windows have more features then I knew. I absolutly LOVE them! I would recommend Flawless Solutions to anyone. I have already talked to some of my neighbors that asked about my new windows and my family."

FAQs for doors (exterior) installation and replacement projects in Northglenn, CO

If your entry bakes in direct sun, fiberglass is the clear winner. The material shrugs off extreme heat, stays energy-efficient, and won’t warp or fade the way wood sometimes can. Paired with low-E or UV-blocking glass, a quality fiberglass door keeps hot air out, cool air in, and should serve you reliably for roughly two decades.

A seasoned door pro can hang a replacement door in two to four hours—mounting the slab, tweaking the fit, and adding hinges, knobs, and weatherstripping. If the jamb needs repairs or you’re cutting a brand-new opening, plan on extra time so everything lines up and seals tightly. Either way, most projects wrap up in a single afternoon.
