How Installing Energy-Efficient Windows in Dunkirk Saves You Money

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

• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save on electricity bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Dunkirk

Windows come in all shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you’ll find from window installation companies.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Dunkirk homeowners $386+ a year when replacing single-pane windows.

We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

When considering window replacements, there are generally two types that your provider will offer: full-frame and pocket installations.

Full-frame installations involve replacing the complete window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. These installations are more involved and will raise overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installation company should be able to help you decide which type of installation you need.

Service Area

Since this is a guide for Dunkirk, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Dunkirk.

Customer Reviews

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

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the most 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

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

Years of Experience

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