How Installing Energy-Efficient Windows in Whittier Saves You Money

There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:

• Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Whittier

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

How Much Do New Windows Cost?

Generally, Whittier homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. But costs differ remarkably depending 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.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

When it comes to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot. These installations are more involved and will increase the total cost. Pocket installations are on the simpler end and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Whittier, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

Energy-efficient 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 Whittier, we paid more attention to companies that serve 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 Whittier.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included on this list 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

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

Cost

This one is a give-and-take: similar to most services, cheap window installers won’t always provide the most quality service. On the other hand, 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

As discussed, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
