How Installing Energy-Efficient Windows in Southampton Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to consider making the switch:

• Save money on electricity bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $215 annually on your energy bills in Southampton.
• Reduce your carbon footprint: In Southampton, you can lower your indirect greenhouse gas emissions by about 307 pounds per year once you upgrade to energy-efficient windows.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Southampton

Windows come in varying purposes, styles and shapes, so costs and services will differ greatly depending on several factors. Below, we go over the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

On average, homeowners in Southampton can anticipate that most window installations will cost between $250 and $1,200, with the average cost at about $600. This is because the cost of window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the sill, trim and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable rot or deterioration. Because these installations are more involved, they will raise overall costs. A pocket installation entails replacing a window without taking out the entire frame, which is generally cheaper than a full-frame installation.

If you’re still debating which kind of installation you should get, you can consult with your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Southampton

EcoWatch reviews are different from other reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Southampton so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company included in our guide to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive 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: similar to other services, cheap window companies won’t always provide the most quality service. On the other hand, 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. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Southampton’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Southampton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
