Window replacement costs in Denver, Colorado, average $4,777, with most homeowners paying between $2,076 and $7,489. It makes sense to invest in high-quality window materials that can cope with the significant temperature fluctuations that high-altitude, semi-arid Denver experiences. Because local costs are lower than the national average, purchasing premium fiberglass frames or triple-pane glass can be affordable.
Window Replacement Cost Factors
Window replacement costs in Denver, Colorado, can range from as little as $270 to as much as $14,000. It’s not just the number of windows you’re replacing that influences your overall budget. The four-season climate and fluctuating temperatures are key factors to consider.
Number of Windows
Expect to pay an average of $600 per window in Denver, Colorado. With most homes having between eight and 12 windows, the average cost to replace all the home’s windows is between $4,800 and $7,200.
| Number of Windows | Price Range |
|---|---|
| 6–8 | $3,000–$5,500 |
| 8–12 | $4,000–$8,200 |
| 12–16 | $6,000–$11,000 |
| 16–20 | $8,000–$13,800 |
| 20–24 | $10,000–$16,500 |
| 25 | $12,500–$17,000 |
Material
Vinyl is a wallet-friendly window frame option in Denver, Colorado. Alternatively, investing in fiberglass frames is a good long-term investment when you have a bigger budget. Both these materials can handle the extreme temperature fluctuations the region can experience, particularly in the spring months. It’s not uncommon for daytime temperatures to be up in the seventies only to drop within a few hours to the thirties. Vinyl and fiberglass frames are more resistant to expansion and contraction than wood or aluminum.
| Material | Pros | Cons | Average Cost |
|---|---|---|---|
| Aluminum | Durable | Heat absorbent | $75–$400 |
| Vinyl | Energy-efficient | Minimal expansion and contraction | $100–$900 |
| Composite | Heat-resistant | UV ray fading | $300–$1,200 |
| Heat-resistant | Prone to expansion and contraction | $150–$1,300 | |
| Fiberglass | Flexible and durable | High cost | $500–$1,500 |
Glass Type
Following the introduction of a 2026 Colorado law, all new or replacement home windows must be Energy Star-rated. While compliance comes at a higher cost, it’s also a good long-term investment. Energy-efficient windows help keep your home warm in the region’s colder winters and cool when the summer heat arrives.
It’s best to consult with a window professional in Denver about which glass is best for your home. The city sits above 5,000 feet, and some types of insulating glass can experience problems with bowing, breakage, and performance loss at this altitude.
| Type of Glass | Qualities | Average Cost |
|---|---|---|
| Single-pane glass | Cost-effective and easy maintenance, but poor insulation | $100–$400 |
| Double-pane glass | Durable and heat-resistant | $300–$2,000 |
| Triple-pane glass | Highly heat-resistant, but high cost | $600–$3,000 |
| Low-emissivity (Low-E) glass | Energy-efficient, but can reduce natural light | $300–$1,100 |
Window Replacement Pro Costs
Handy homeowners with advanced DIY skills can learn how to install replacement windows. However, hiring a local window contractor to tackle this challenging home improvement project is often best. Keep these Denver-specific cost factors in mind when reviewing pro quotes.
Labor
Construction costs in Denver are similar to the national average. Unless you are replacing windows yourself, budget for a local window company to charge between $100 and $300 per window for installation.
Permit
Budget between $35 and $220 for building permit costs for replacement window work in Denver, Colorado. The exact fee you pay depends on the total project valuation.
Licensing
Don’t cut costs by hiring an unlicensed window contractor. Although there is no state-level licensing requirement for window contractors in Denver, Colorado, local regulations are strict. Hiring a locally licensed contractor reduces the risk of wonky window installation that doesn’t meet local building code standards.
You can verify a window contractor’s license via the City and County of Denver website.
Tipping
It’s not necessary, but tipping your contractor between 10% to 20% of the original estimate for a job well done is always appreciated. If your contractor has gone above and beyond, budget between $200 and $1,500 to say thanks, or leave them a positive review and offer to write a recommendation letter for future business.
Does Window Replacement Increase Home Value?
New windows can increase your home’s value, provided you hire a licensed local contractor to carry out quality, building-code-compliant work. The average return on investment for window replacement costs in Denver, Colorado, is 70% to 80%. Although window replacement isn’t the flashiest of upgrades, it can increase home comfort and curb appeal while lowering energy bills—all attractive selling points for potential buyers.
