How Installing Energy-Efficient Windows in Norwalk Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:

• 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.
• Reduce your carbon footprint: In Norwalk, you can cut your indirect greenhouse gas emissions by about 147 pounds per year when you upgrade 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Norwalk

Each window installer offers various services and has varying costs based on a few factors.

How Much Do New Windows Cost?

Even though the typical cost to replace a single window is about $600, it can range from $200 to $1,200. These estimates vary based on the specifics of your installation, such as number of windows, material, the location of your home, size, type and more.

Keep in mind that energy-efficient windows may have a higher price, 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 a year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Asking for free quotes from several installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant damage. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you decide what’s best for your needs. In Norwalk, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Norwalk

In our search to make your home improvements easier and more eco-friendly in Norwalk, EcoWatch evaluated many companies before settling on these. We’ve reviewed the top window replacement companies in Norwalk primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Norwalk, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Norwalk.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer 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

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good feedback 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 installation companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why 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 been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
