How Installing Energy-Efficient Windows in Southport Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Southport, that's about 65 pounds per year on average.
- Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Southport
Windows come in all shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. Costs will differ considerably depending on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Southport homeowners $406+ each year after replacing single-pane windows.
We advise getting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when planning a window installation is to think about whether you need a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Southport
EcoWatch differs from most reviewers because we look at these companies through a sustainability lens. We have evaluated the best window replacement companies in Southport mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Southport area so you can find the right 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 company in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of parts, warranty, 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 as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Southport's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Southport window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Southport, NY Window Replacement FAQs
How much does a window install cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
When should I use a window installation company?
Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring the pros. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.
How long does it generally take to install windows?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, the weather should be dry, as rain can make the installation harder.
