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 green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy 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 If your house has traditional, outdated windows, your HVAC system could be working extra hard to heat or cool your house. This means spending more on electric bills.

That's bad for your wallet and the environment, but one of the best window installation companies can help you with that.

So if you're building a new home, renovating or changing out old windows in Glendale, this is the best place to get started.

How Installing Energy-Efficient Windows in Glendale Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could benefit you:

  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 460 pounds.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Glendale

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. These estimates vary depending on specific characteristics of your installation, including the location of your home, number of windows, material, type, size and more.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $378 a year on your energy bills in Glendale.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window replacement is to figure out whether you need a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you're still debating which kind of installation to get, you can talk to your installer and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Glendale

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Glendale and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer 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. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, quality of parts, cost and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Glendale's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Glendale window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Glendale, CO Window Replacement FAQs

How much should window installation cost?

The typical cost of replacing one window can range between $450 and $650. There are a variety of factors that affect the cost, including your property's location, how energy-efficient the windows are, the materials used in designing the windows, the number of windows, styles and sizes of windows and local labor costs.

Which type of window is the best?

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're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

Can you replace your own windows?

If you're handy and know how to replace a window, you may be able to install your own windows. However, if you don't have the time or skills, we don't recommend trying it.

What time of year should I replace my windows?

While you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn't be raining, since rain can make the installation more difficult.

How often do you need to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
