How Installing Energy-Efficient Windows in Chesterfield Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could help you:

• Reduce your carbon footprint: In Chesterfield, you can lower your indirect greenhouse gas emissions by about 763 pounds per year after you install energy-efficient windows.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Chesterfield

When considering window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

According to our research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. This is because the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Chesterfield homeowners $376+ each year after replacing single-pane windows.

How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are typically 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 generally two types of window replacement services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot. With this service, your installers will replace the entire window, including the sill, trim and frame. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re not sure which type of window installation service you should get, your installer can advise you. In general, the decision is influenced by 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 Chesterfield

In our hunt to find the most reliable, eco-friendly window installers in Chesterfield, EcoWatch examined many companies before deciding on these. We’ve decided to review the top window installers in Chesterfield primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your electricity 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 Chesterfield, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Chesterfield.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, quality of installation, warranty, quality of parts, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you 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 been in the industry for quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
