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.

Living RoomsDining RoomsFront-Facing Walls

Why Bay & Bow Windows

Six Reasons Utah Homeowners Choose Bay & Bow

Flood of Natural Light

Multiple angled panels capture light from three or more directions throughout the day, dramatically brightening interior spaces, even on Utah's shorter winter days.

Panoramic Mountain Views

The angled or curved projection creates a wide-angle sightline that flat windows can't match. Frame the Wasatch Range, Oquirrh Mountains, or your garden in a single sweep.

Added Usable Space

Bay and bow windows project 12–24 inches outward, creating a built-in shelf, window seat, or reading nook, usable square footage without the cost of an addition.

Energy-Efficient Engineering

Each panel uses the same ENERGY STAR Low-E glass packages as our flat windows. Insulated head and seat boards prevent thermal bridging at the projection joints.

Ventilation on Multiple Sides

Operable flanking panels let you catch cross-breezes from different angles, something no single flat window can do. Ideal for Utah's dry-climate natural cooling.

Structural Integrity

Every EPIC bay and bow installation includes engineered steel support brackets, flashed and insulated head/seat boards, and proper load-bearing verification, built to handle Utah snow loads.

The Process

How Your Bay & Bow Window Install Works

Bay and bow installations are more involved than standard replacements. Here's how EPIC handles every detail.
