Our new glass doors open up the rooms more than we expected and Epic Windows and doors did a great job making sure everything was measured and installed perfectly. We love the doors and would use and recommend Epic doors again.

Gabe was great. He came over about an hour after we called and fixed our door. He was so kind and gracious. Great service by Gabe and Epic! Definitely recommend them.

I’m an exteriors contractor and have been super impressed by the level of follow-up from both Broc and Ryan. Their ability to stay on top of projects and make sure things are moving forward on behalf of their customers really stands out to me as the one doing the exterior work around the beautiful new windows they install. I would recommend them both as great reps who stand up for their clients.

I've been working with Loren and I'm very pleased with the manner in which he conducts himself. Solid individual that will make you laugh while saving you money and time. Good company with good Utah values.

EPIC completely transformed the front of our home. The team was professional, fast, and the windows look absolutely stunning. Every neighbor has already asked who we used. Worth every penny.

We saved up for years to replace our front door and patio doors. Worked with Zach who was amazing, patient, professional, and honest. The finished result exceeded every expectation. Absolutely love it.

Had them out to service my windows and doors installed 15 years ago. Service tech was excellent, very knowledgeable. EPIC stands behind their work long term, and that says everything about a company.

From first call to final installation, completely flawless. The new entry door alone made our house look like a completely different home. Incredible craftsmanship.

Got 4 different quotes, EPIC came in lowest by a significant margin. Quality blew us away. Energy bill dropped noticeably. Wish we'd done this years ago.

Just had 8 windows replaced and couldn't be happier. The installers were clean, fast, and incredibly professional. My home is noticeably warmer and quieter already.

Best home investment we've made in 10 years. EPIC was honest about what we needed (and what we didn't). That kind of integrity is rare. Will absolutely use them again.

Called three companies and EPIC was the only one who came out same day to measure. Quote was clear, no hidden fees, and the install was flawless. Highly recommend.

Our energy bill went down $80 the first month after the new windows. The team was in and out in one day. Best decision we made this year.

Why Patio & Sliding Doors

Six Reasons Utah Homeowners Choose Patio Sliding Doors

Expansive Glass, Minimal Frame

Sliding door panels maximize the glass-to-frame ratio, flooding your living space with natural light and providing unobstructed views of Utah's mountains and landscapes.

Low-E Argon Insulated Glass

Dual-pane Low-E glass with argon gas fill delivers U-factors as low as 0.22, blocking winter cold and summer heat while reducing UV damage to your interior furnishings.

Multi-Point Lock + Foot Bolt

A multi-point locking system secures the panel at multiple points along the frame, and an integrated foot bolt provides additional resistance against forced entry at the floor.

Heavy-Duty Rolling Hardware

Tandem steel rollers on a precision track ensure smooth, effortless operation year after year, even on 12-foot, four-panel configurations.

UV Protection for Interiors

Low-E coatings block up to 95% of UV rays, protecting hardwood floors, rugs, and furniture from fading, critical at Utah's 4,000–6,000 ft. elevation where UV intensity is higher.

Low-Maintenance Operation

Vinyl and fiberglass frames never need painting or staining. The track design keeps debris out, and the panels lift out for easy cleaning of exterior glass.
