How Installing Energy-Efficient Windows in Littleton Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• More efficient energy use in your household: Because the summers can get pretty warm in Littleton, homeowners often rely on their air conditioner during that time. Energy-efficient windows lower how much cool air is lost through your windows, which makes it easier to keep your house cool.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Littleton

Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you'll find from window installers.

How Much Do New Windows Cost?

On average, Littleton homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at about $600. These amounts are based on the specifics of your installation, including size, material, number of windows, type, the location of your home and more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Littleton homeowners $560+ per year after replacing single-pane windows.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely 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?

In regard to window installations, in general there are two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are simpler and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Littleton

EcoWatch reviews differ from other reviews since we look at these companies through a sustainability lens. We have assessed the top window installation companies in Littleton mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, warranty, quality of parts, professionalism, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a serious 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

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
