How Installing Energy-Efficient Windows in Sterling Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could help you:

• Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Sterling

Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from window installation companies.

How Much Do New Windows Cost?

Generally, homeowners in Sterling can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These numbers are based on the specifics of your installation, such as the location of your home, number of windows, type, size, material and more.

It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Sterling home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary based 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 offer 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 offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window installation is to figure out whether you need a full-frame or pocket installation.

Full-frame installations involve replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. These installations are more involved and will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re unsure which kind of window installation service you need, your installer can advise you. Typically, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Sterling

EcoWatch reviews are different from other reviews because we’re examining these companies through a sustainability lens. We’ve reviewed the best window replacement companies in Sterling mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Sterling, we only included companies that provide services to the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Sterling.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company included in our guide to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good things to say about their service from a certain window installation 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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

Due to Sterling’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Sterling window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
