How Installing Energy-Efficient Windows in Waterbury Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to take the plunge and make the switch:

• Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if your home is on the older side.
• 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.
• Save on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $420 annually on your energy bills in Waterbury.

Estimated Cost of Window Replacement in Waterbury

Windows come in different styles, shapes and purposes, so costs and services will differ considerably depending on several factors. Below, we go over the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Even though the average cost to replace one window is about $600, it can range from $200 to $1,200. But costs will differ significantly based on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Waterbury homeowners $420+ a year when replacing single-pane windows.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the entire 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 deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should be able to help you understand what’s best for your needs. In Waterbury, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Waterbury

EcoWatch reviews are different from most reviews, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Waterbury and assigned rankings using the following methodology:

Service Area

Because this is a guide for Waterbury, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Waterbury.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback 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 the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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