How Installing Energy-Efficient Windows in Southampton Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- More efficient energy use in your home: In Southampton where the summers can be quite hot, energy-efficient windows decrease the amount of cool air that is lost through your windows, making it easier to keep your house cool.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- More efficient energy usage in your household: Because the winters can get very cold in Southampton, homeowners usually depend on their heater during that time. Energy-efficient windows cut back on the amount of heat that is lost through your windows, which makes it easier to keep your home warm.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Southampton
Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost you varies depending on several factors, including type, the location of your home, size, material, number of windows and more.
It's important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Southampton homeowners $215+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations are simpler and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
Your window replacement company should be able to help you understand what's best for your needs. In Southampton, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Southampton
EcoWatch reviews differ from other reviews, as we're examining these companies through a sustainability lens. We have evaluated the top window installers in Southampton mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Southampton 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 make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Southampton's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Southampton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
