How Installing Energy-Efficient Windows in Port Wentworth Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• 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.
• Save money on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $340 annually on your energy bills in Port Wentworth.
• Decrease your carbon footprint: In Port Wentworth, you can cut your indirect greenhouse gas emissions by about 476 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Port Wentworth

Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Even though the national average cost to install one window is about $600, it can range from $200 to $1,200. These numbers are based on specific characteristics of your installation, including material, number of windows, type, the location of your home, size and more.

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

Something else that affects the overall cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning an installation is to clarify whether you should get a full-frame or pocket installation.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Port Wentworth

In our hunt to find the most reliable, eco-friendly window installers in Port Wentworth, the EcoWatch Reviews team assessed many companies before settling on these. We have reviewed the best window replacement companies in Port Wentworth mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Port Wentworth, we gave more points to companies that serve the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Port Wentworth.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window installers won’t always provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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