"It was for a big deal for $1,199.00 for a Pella Encompass Sliding Patio Door, Including Installation. There was no extra charges. I called them about something and they did not call me back."

"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 Boulder, 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.
