How Installing Energy-Efficient Windows in Weston Saves You Money

There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.

Estimated Cost of Window Replacement in Weston

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

How Much Do New Windows Cost?

Generally, Weston homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. Costs will differ significantly depending on the quality of your products, the current condition of your home, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Weston homeowners $441+ a year when replacing single-pane windows.

Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase 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) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can advise you on the best type for your project. In Weston, the decision will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Weston

In our hunt to make your home improvements easier and more eco-friendly in Weston, the EcoWatch team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Weston area 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 featured on this list to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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

Weston, CT Window Replacement FAQs

How much does window installation cost?

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

What type of window is the best for energy efficiency?

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’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

If you’re handy and know how to replace a window, it’s possible to install your own windows. However, if you don’t have the time or know-how, we don’t recommend trying it.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
