Since 2004

Window costs for the Front Range, since 2004

Most window companies will not name a price until someone is at the kitchen table. That meeting is built for one number, theirs. Denver Window has published Front Range cost ranges since 2004 so a homeowner can walk into that meeting already holding a range and one technical question that only a company working at this altitude can answer.

Why the Front Range is the brief

A sealed glass unit is not a commodity here. Denver sits at 5,280 feet, so a unit assembled near sea level arrives with the panes already bowed. Hail along this corridor dents cladding and cracks vinyl at the welds months before the water shows up. A thirty-degree swing between afternoon and dawn works the frame against the glass every ordinary spring day. Those three conditions are why the cost pages on this site are specific, dated, and unwilling to repeat a tax credit that no longer exists.

What this site publishes

  • Installed cost ranges for replacement, plus installation, repair, and cleaning guides.
  • A directory of 24 Denver window companies with public ratings as of 22 August 2026. A listing is not an endorsement.
  • A checklist for collecting your own quotes: the altitude question, the lines on a bid, and how to verify a licence.

Cost ranges are for budgeting. Your contract, if you sign one, is between you and the company you hire. The Terms of Use set that out.

Verify a contractor yourself. It takes ten minutes.

  1. Ask for the licence number and check it with the city or county building department that issues it. Colorado licenses at the local level for most trades, so the right office depends on your address.
  2. Ask for a certificate of insurance sent directly from the insurer or agent, not a photocopy from the contractor's folder. You want general liability, and workers compensation if they have employees.
  3. Check the Colorado Secretary of State business registration. A trade name with no registered entity behind it is a warning.
  4. Read reviews with the dates showing. A five-year-old reputation and this year's crew are not the same thing.
  5. Get everything in writing before you pay a deposit. Scope, model numbers, permit responsibility, warranty terms, and what happens if the lead time slips.

How we write what is on this site

The cost figures, code numbers and technical explanations here are researched from industry pricing data, building code text and manufacturer documentation, and they are dated. Where a number is a range, we say so. Where a rule changed, we say when.

One example of what that means in practice. The federal Energy Efficient Home Improvement Credit under Section 25C, which used to cover part of the cost of efficient windows, was terminated for property placed in service after 31 December 2025 by the One Big Beautiful Bill Act. A great many window websites still advertise it. We do not, because a homeowner who budgets around a credit that no longer exists gets hurt by that.
