How Installing Energy-Efficient Windows in Watertown Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Decrease your carbon footprint: In Watertown, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you upgrade to energy-efficient windows.
  • Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Watertown

Each window installer provides varying services and has varying prices based on a few factors.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.

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

Requesting free quotes from multiple companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you're still debating which kind of installation to get, you can consult with your provider and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Watertown

The EcoWatch Reviews team is different from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Watertown and ranked them using the following methodology:

Service Area

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

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 included in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, quality of parts, cost, professionalism, quality of installation and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like 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 substantial investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Watertown, CT Window Replacement FAQs

How much does window installation cost?

The typical cost of installing a window ranges between $450 and $650. There are many factors that influence how much it costs, such as your property's location, how energy-efficient the windows are, the number of windows, local labor costs, styles and sizes of windows and the materials used in designing the windows.

What are the most common types of replacement windows?

The most common kinds of windows for homes include: awning windows, casement windows, slider windows, double-hung and single-hung windows, picture windows, bay windows and transom windows.

What services do window replacement companies offer?

Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.

How long does window installation take?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.

How often do you need to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
