How Installing Energy-Efficient Windows in South Whittier Saves You Money

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

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In South Whittier, you can cut your indirect greenhouse gas emissions by about 117 pounds per year once you switch to energy-efficient windows.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
  • Save money on power bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $509 annually on your energy bills in South Whittier.

Estimated Cost of Window Replacement in South Whittier

When researching window installation, each company offers varying services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Generally, homeowners in South Whittier can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost sitting 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 installations, which will make your project cost more.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in South Whittier.

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

What Services do Window Installers Offer?

There are typically two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve 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 surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in South Whittier

In our hunt to make your home improvements easier and more eco-friendly in South Whittier, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the South Whittier area so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have nice things to say about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try 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

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

Years of Experience

Because of South Whittier’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of South Whittier window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

South Whittier, CA Window Replacement FAQs

What is the typical cost to install windows?

The national average cost to install a single window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

Do you really need to use a window installation company?

Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.

What time of year should I replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
