How Installing Energy-Efficient Windows in Dunkirk Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Dunkirk
When looking into window installation, each company provides different services and costs. Let's go over some average costs and services.
How Much Do New Windows Cost?
Although the typical of replacing one window is about $600, it can range from $200 to $1,200. These numbers vary based on the specifics of your installation, including number of windows, material, type, the location of your home, size and more.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
We recommend requesting free quotes from multiple window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step when considering a window installation is to decide whether you need a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the full window, including the trim, frame and sill. A pocket installation involves installing a new window within the frame that's already there. This means instead of taking out the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which type of window installation service you should get, your installer can assist you. Generally, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Dunkirk
In our hunt to make your home improvements easier and more eco-friendly in Dunkirk, the EcoWatch team evaluated many companies before landing on these. We have decided to review the top window installation companies in Dunkirk mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Dunkirk, we only included companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Dunkirk.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, cost, warranty, quality of parts and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, 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.
Dunkirk, NY Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your home, including awning windows, slider windows, bay windows, casement windows, picture windows, double-hung and single-hung windows and transom windows.
What do window installers do?
Window installers will do the entire process — from replacing your old windows with brand new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
Should I replace my windows all at the same time?
If you're upgrading your windows because of energy-efficiency, replacing all your windows at the same time is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
