How Installing Energy-Efficient Windows in Glendale Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 460 pounds.
  • More efficient energy usage in your home: In Glendale where the summers can get quite hot, energy-efficient windows lower the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.

Estimated Cost of Window Replacement in Glendale

Each window installer provides varying services and has varying price points based on several factors.

How Much Do New Windows Cost?

Typically, homeowners in Glendale can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But prices differ 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 provide door replacements, which will add extra costs to your project.

It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Glendale home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies provide: full-frame and pocket installations.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Glendale, the choice will mostly be based on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Glendale

In our hunt to find the most reliable, eco-friendly window installers in Glendale, EcoWatch evaluated dozens of companies before settling on these. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:

Service Area

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

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Glendale, CO Window Replacement FAQs

What is the average cost to install new windows in a home?

The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by 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 initially but can save you hundreds of dollars a year in energy bills.

What are the most common kinds of replacement windows?

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

What services do window replacement companies offer?

Window installers travel to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

How long does window installation generally take?

Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
