How Installing Energy-Efficient Windows in Watertown Saves You Money

When you switch to energy-efficient windows, you may see several perks, such as:

  • Reduce your carbon footprint: In Watertown, you can lower your indirect greenhouse gas emissions by about 147 pounds per year after you switch to energy-efficient windows.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Watertown

Let’s take a look at the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Typically, homeowners in Watertown can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. These numbers vary based on specific characteristics of your installation, like the location of your home, material, type, size, number of windows and more.

It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Watertown homeowners $486+ a year when replacing single-pane windows.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether 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 shown to be more efficient.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the whole window, including the frame, sill and trim. A pocket installation entails replacing a window within the existing frame. This means instead of tearing out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation you should get, you can ask your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Watertown

EcoWatch is different from most reviewers since we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Watertown so you can find a quality window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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

Watertown, CT Window Replacement FAQs

How much should a window install cost?

The average cost of replacing one window ranges from $450 to $650. There are a variety of factors that influence the cost, which include the materials used in designing the windows, local labor costs, your property’s location, styles and sizes of windows, how energy-efficient the windows are and the number of windows.

Which type of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.

When should I use a window installation company?

Unless you’re handy and have all the necessary tools to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.

When is it time to replace your windows?

Windows typically have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have an expert take a look at them to see if they need any repairs or replacements.
