Cost to Replace Windows in Denver, CO (2027 Price Guide)
Price your windows in Denver, CO
Plan on about $4,880 to $8,250 to put 10 new double-hung vinyl windows into a Denver home. That works out to $487.81-$824.62 a window, with $5,810 as the middle-of-the-road figure.
Those figures use our windows calculator with its standard options: Low-E glass with argon fill, basic build quality, no grids and the existing interior trim reused. Prices here run about 4% below the national average. Busier metro crews and higher overhead push Denver prices roughly 4% above the statewide figure of $4,700 to $7,940 for this job.
What Each Window Material Costs in Denver
Here is the same 10-window job in each frame the calculator offers. Wood runs $7,750 to $13,090 and fiberglass $8,390 to $14,180, so vinyl wins on price by a wide margin. Window style matters too. One double-hung unit runs about $580.72 installed, a two-lite slider about $915.71, and a bay or bow about $3,356.95.

Build Your Order: Upgrades for 10 Windows
What the common extras do to the 10-window estimate in Denver:
What Denver Weather Asks of a Window
Cold snaps around 14°F punish leaky sash. In this climate, a well-sealed vinyl or fiberglass frame with Low-E/argon glass is the value choice; frost on the inside of old windows is a sign they are due.
Climate regions run from 1 (cool) to 5 (hot); Colorado sits in region 1.
Hail season is a reason to keep good records: photos and the window order show an adjuster what was installed. Large stones can crack vinyl frames, so read the warranty's storm-damage terms.
In a cold climate, compare bids by U-factor (lower is better) as well as by price. Triple-pane glass is an option for the coldest walls; ask for it as a separate line so you can see what it adds.
In wildfire country, the glass type is a code question. Tempered panes resist heat cracking far better than standard glass; check your local fire zone map before you approve a quote.
Spring through fall is the easy stretch for an install. Crews do work in winter, one opening at a time, but sealants cure slowly in the cold, so ask how they handle it. Window prices for Denver (Denver County) are worked out apart from those of Lakewood, the nearest listed city, about 7 miles west.
How to Compare Window Bids in Denver
Before you pick a bid in Denver, make every installer cover the same three points:
- Same product line. Compare brand, series and frame material, not just the price per window.
- Installation details. Look for flashing, low-expansion foam and exterior caulk on the scope sheet.
- Upgrades. Grids add about $380 across 10 windows here; leave them off if you do not want them.

Window Replacement Questions
What is the timeline from quote to install?
No - each window is removed and the new one set and sealed within a few hours. The whole set of 10 is often done in a day or two once the order arrives.
How much is a single new window in Denver?
Per opening, plan on $487.81-$824.62 for a vinyl double-hung. A slider comes to about $915.71; ordering one or two units alone usually costs more each.
Is fiberglass worth the extra cost over vinyl?
For budget and low upkeep, vinyl is hard to beat. Fiberglass ($8,390 to $14,180 here) and wood ($7,750 to $13,090) make sense for historic looks, big glass areas or homes where resale buyers expect them.
