How Installing Energy-Efficient Windows in Glendale Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, including:

• Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.

How Much Do New Windows Cost?

Generally, homeowners in Glendale can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at around $600.

Getting free quotes from multiple companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the complete window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has considerable rot or deterioration. Because these installations are more involved, they will raise the total cost. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you figure out what’s best for your needs. In Glendale, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Glendale

The EcoWatch Reviews team differs from other reviewers because we evaluate these companies through a sustainability lens. We have assessed the top window installation companies in Glendale mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Glendale, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Glendale.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Due to 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.
