Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a considerable impact on home energy conservation. If your house has traditional, outdated windows, your HVAC system could be working extra hard to heat or cool your home. This means spending more on electric bills.

That’s not great for your bank account or the environment, but one of the best window installation companies can help with that.

Unlike other review sites, EcoWatch ranks window companies on energy efficiency while also factoring in cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Gunbarrel Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could help you:

  • Save on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Gunbarrel

Each window replacement company provides various services and has varying costs depending on several factors.

How Much Do New Windows Cost?

On average, homeowners in Gunbarrel can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will make your project cost more.

It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Gunbarrel homeowners $457+ a year when replacing single-pane windows.

Something else that affects the overall cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?

Full-frame installations entail replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has noticeable damage. These installations are more involved and will increase the total cost. A pocket installation means replacing a window without removing the entire frame, which is generally cheaper than a full-frame installation.

Your window installer should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Gunbarrel

The EcoWatch Reviews team is different from other reviewers since we examine these companies through a sustainability lens. We have reviewed the top window installers in Gunbarrel mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Gunbarrel, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Gunbarrel.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of parts, warranty, professionalism, quality of installation and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Gunbarrel’s climate, homeowners need to be wary of rot, low efficiency and water damage. 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 does window installation cost?

The average cost to install a window can range from $450 to $650. There are several factors that affect the cost, which include the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property’s location, the number of windows and styles and sizes of windows.

What are the most common types of replacement windows?

There are various kinds of windows you can get for your home, such as double-hung and single-hung windows, picture windows, slider windows, transom windows, bay windows, casement windows and awning windows.

What do window installation companies do?

Window installers visit your house to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, because rain can make the installation harder.

How often do you need to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
