How Installing Energy-Efficient Windows in Gunbarrel Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save about $457 annually on your energy bills in Gunbarrel.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Gunbarrel
When researching window installation, each company provides varying services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
On average, homeowners in Gunbarrel can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost you is based on several factors, like type, size, material, number of windows, the location of your home and more.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Gunbarrel homeowners $457+ a year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you choose. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
When considering window installations, there are generally two types that your provider will offer: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the total window, including the sill, trim and frame. Pocket installations are on the simpler end and won't cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Gunbarrel, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

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 are the kinds of windows?
There are several different kinds of windows you can get for your home, including casement windows, bay windows, awning windows, transom windows, double-hung and single-hung windows, slider windows and picture windows.
What services do window installation companies provide?
Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation harder.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
