How Installing Energy-Efficient Windows in Westbrook Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could benefit you:

• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Westbrook

Windows come in varying shapes, purposes and styles, so costs and services will differ greatly depending on your project. Below, we go over the typical cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

Typically, Westbrook homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. This is because the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Westbrook homeowners $396+ a year after replacing single-pane windows.

Requesting free quotes from multiple providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the sill, frame and trim. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Westbrook

In our search to find the most reliable, eco-friendly window installers in Westbrook, the EcoWatch team examined dozens of companies before settling on these. We’ve assessed the best window replacement companies in Westbrook mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Westbrook area so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

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

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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