How Installing Energy-Efficient Windows in Glendora Saves You Money

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

• Reduce your carbon footprint: In Glendora, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that amount, which helps you save more on your bills.
• Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Glendora

Each window replacement company offers varying services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

On average, Glendora homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These estimates vary depending on the specifics of your installation, such as number of windows, material, size, the location of your home, type and more.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Glendora homeowners $506+ a year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most 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 when planning an installation is to figure out whether you should get a full-frame or pocket installation.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which increase the overall 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 (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to recommend the best type for your project. In Glendora, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Glendora

The EcoWatch Reviews team is different from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Glendora and ranked them based on the following methodology:

Service Area

Because this is a guide for Glendora, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Glendora.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, quality of installation, quality of parts, cost and more.

Cost

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

Warranty

As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) 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 earn higher rankings by our standards. We like to see at least ten years of experience.
