How Installing Energy-Efficient Windows in Gunbarrel Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Better temperature control in your home: Living in a hot place like Gunbarrel usually means depending on your air conditioner to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- More efficient energy use in your household: Because the winters can get very cold in Gunbarrel, homeowners usually depend on their heater a lot. Energy-efficient windows reduce how much heat is lost through your windows, which makes it easier to keep your house warm.
Estimated Cost of Window Replacement in Gunbarrel
Windows come in various purposes, styles and shapes, so costs and services will vary considerably based on several factors. Below, we describe the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will add extra costs to your project.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
We recommend getting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
When it comes to window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you choose what's best for your needs. In Gunbarrel, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Gunbarrel
EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Gunbarrel, we only included companies that serve the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Gunbarrel.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, cost, quality of installation, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Gunbarrel's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Gunbarrel window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Gunbarrel, CO Window Replacement FAQs
How much should window installation cost?
The national average cost to install one window is about $600 but can range between $200 and $1,200, depending on several factors. The price is often dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or know-how, we don't recommend trying it.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
