Window Replacement

New windows, quoted fast — often without anyone coming out.

Many window projects can be quoted right over the phone — no in-home sales visit, no pressure, no lost evening. Prefer to have someone measure in person? We'll set that up too. Either way, you're matched with a vetted local installer.

Why homeowners replace their windows

Lower energy bills

Old single-pane or failed double-pane windows leak money all year. Modern low-E, insulated glass keeps Colorado heat out in summer and in during winter.

A more comfortable home

No more cold drafts by the couch or rooms that never hold temperature. New windows even out comfort and cut down outside noise.

Curb appeal and resale value

New windows are one of the most visible upgrades you can make, and they consistently return a strong share of their cost at resale.

Less upkeep, better security

Modern vinyl and fiberglass frames don't rot, warp, or need repainting, and newer locking hardware is far more secure than aging windows.

Two ways to get your window quote

Most window projects don't need a salesperson in your living room. Choose whatever's easiest for you.

Fastest — most homeowners pick this

Quick phone or virtual quote

Share your window count, the styles you have, and a few photos or rough measurements. Many window projects can be quoted right over the phone or by video, often the same day. No salesperson in your living room, no high-pressure pitch, no lost evening.

Available whenever you want it

Prefer an in-home estimate? We do that too.

Some projects — full-frame replacements, tricky or non-standard openings, or simply when you'd rather have someone measure in person — are better handled on-site. We'll set up a no-pressure in-home visit with your vetted local installer.

Either way, you're matched with the same vetted local installer — and there's never any obligation to move forward.

What a window replacement typically includes

  • Removal and disposal — Careful removal of your old windows and haul-away, so nothing is left behind.
  • New window units — Quality vinyl, fiberglass, or wood windows in the styles and finishes you choose.
  • Professional installation — Level, square, and properly fastened — the single biggest factor in how windows perform.
  • Flashing and sealing — Proper flashing, insulation, and weather sealing around each opening to stop leaks and drafts.
  • Interior and exterior trim — Trim, casing, and finish work so the new windows look clean inside and out.
  • Low-E, energy-rated glass — Insulated glass appropriate for Colorado's climate and sun exposure.
  • Manufacturer warranty — Window and labor warranties registered so you're covered down the road.
  • Permits where required — Any permits and inspections your jurisdiction requires, handled as part of the job.

What to expect on cost and timeline

Window replacement projects in Colorado usually average between $1,000 and $1,200 per window installed, with smaller windows coming in under that and larger or specialty units running higher. A whole-home replacement of 10–15 windows typically lands somewhere around $10,000 to $18,000, depending on the count, size, material, and how the windows are installed.

Getting a quote is quick — often the same day by phone. Once you order, most windows are made to measure, so plan for a few weeks of lead time before install. The installation itself is fast: most homes are finished in one to two days.

Key insight

The biggest cost drivers are the number of windows, the material and glass package you choose, and whether it's a simple insert or a full-frame replacement. Buying the whole home at once is almost always cheaper per window than doing it piecemeal.

Common window projects

Whole-home replacement

Whole-home replacement

Replacing every window in the house at once — the most cost-effective way to buy, and the biggest jump in comfort and efficiency.

A few windows or one room

A few windows or one room

Replacing failed, foggy, or damaged windows a few at a time, or updating a single room. Straightforward and often quotable by phone.

Specialty and new openings

Specialty and new openings

Bay and bow windows, large picture windows, egress windows for a basement bedroom, or cutting in a brand-new opening.

What to know before you start

Match the material to your goals

Vinyl is the value workhorse; fiberglass and composite are stronger and hold paint; wood is premium and classic. A good installer will walk you through the trade-offs.

Watch the energy ratings

In Colorado, look for a low U-factor (insulation) and an SHGC suited to your sun exposure. ENERGY STAR–rated units for our climate zone are a safe baseline.

Full-frame vs. insert

Insert (pocket) windows fit into the existing frame and cost less; full-frame replacement is more involved but fixes rot and lets you resize. Which one fits depends on your openings.

Plan around lead times

Most windows are made to order, so expect a few weeks between measuring and install day. Ordering early keeps your timeline on track.

Check egress requirements

Any bedroom window — especially in a basement — must meet Colorado egress size rules. A specialist will confirm your openings comply.

Confirm HOA rules first

Some Colorado HOAs restrict window color, grid patterns, and frame style. Worth checking before you order so there are no surprises.
