How Installing Energy-Efficient Windows in Willowbrook Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, such as:

  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on electricity bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save around $531 annually on your energy bills in Willowbrook.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.

Estimated Cost of Window Replacement in Willowbrook

Each window installer offers various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

Although the national average to install a single window is around $600, it can range from $200 to $1,200. How much it will cost is based on several factors, such as material, size, number of windows, type, the location of your home and more.

Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Willowbrook.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat 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 question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

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

Your window installation company can recommend the best type for your project. In Willowbrook, the decision will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Willowbrook

EcoWatch is different from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Willowbrook so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type 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

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their service from a certain company, you won't see it featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies with 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 been in the industry for a while. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Willowbrook, CA Window Replacement FAQs

What is the typical cost to install windows in a home?

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

What kind of window is the most energy-efficient?

A window's energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.

How often do you need to replace windows?

Windows usually last 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them checked by an expert to see if they are in need of a repair or replacement.

Should I replace all my windows at once?

If you're upgrading your windows to get more efficient windows, replacing all your windows together is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
