Expert Window Installation in Utah


New windows cut energy costs, block Utah's temperature swings, and protect your home's frame from moisture. We install double-pane, casement, slider, bay, and picture windows across Herriman and the Wasatch Front.

Replacement Windows That Reduce Energy Costs

Old windows leak conditioned air through worn seals and single-pane glass. That means your furnace and air conditioner work harder every month, and you pay for the difference on your utility bill.

New double-pane and low-E glass windows from Capitol Exteriors hold indoor temperature steady through Utah's hot summers and cold winters. Most homeowners notice a lower energy bill within the first season after installation.

How a Poor Window Seal Raises Your Utility Bills

A failed window seal lets warm or cold outside air pass directly into your home, forcing your HVAC system to run longer to compensate. Over a year, that added strain can raise energy costs by 10 to 25 percent. Resealing or replacing the window stops the leak at its source.

Window Types Capitol Exteriors Installs

Double-Pane Windows — Two layers of glass with insulating gas between them cut heat transfer and noise better than single-pane glass.

Casement Windows — Crank-operated windows that seal tightly against the frame, cutting air leaks to nearly zero when closed.

Slider Windows — Wide horizontal panes that glide open easily, a common fit for bedrooms and family rooms.

Bay Windows — Three-panel windows that project outward, adding natural light and a wider view to a living room or dining space.

Picture Windows — Fixed, non-opening glass built for maximum light and unobstructed views, often paired with operable windows on either side.

Why Utah Homeowners Choose Double-Pane Replacement Windows

Double-pane windows trap insulating gas between two glass layers, which keeps heat inside during Utah winters and outside during summer. Homeowners across Salt Lake and Utah County choose this option because it lowers energy bills and reduces outside noise more effectively than older single-pane windows.

Window Installation Questions Answered

  • How do I know if my window seals have failed?

    Look for foggy or hazy glass between the panes, drafts near the frame even when the window is closed, or condensation building up between the layers of glass. Any of these signs mean the seal has failed and the window is no longer insulating your home the way it should.
  • How long does a window installation take?

    Most single-window replacements take one to two hours. A full-home window replacement with 10 to 15 windows usually takes one to two days, depending on window size, style, and whether we need to make any frame repairs along the way.
  • What time of year is best for window installation in Utah?

    We install windows year-round, including through Utah winters. Each opening is sealed and covered before the old window comes out, so your home stays protected from outside temperatures during the swap, no matter the season.
  • How do I choose the right window style for my home?

    Start with how the window opens and how much airflow you want. Casement and slider styles suit bedrooms, while bay and picture windows work well for living areas that need more light. We walk through your home and recommend styles during your free estimate.
