How Installing Energy-Efficient Windows in Charleston Saves You Money

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

• Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
• Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 777 pounds.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.

Estimated Cost of Window Replacement in Charleston

Let’s go over the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

Though the average cost of installing one window is around $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, including type, the location of your home, material, size, number of windows and more.

Keep 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 you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Another factor that influences the total cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation means replacing a window without removing the entire frame, which is usually cheaper than a full-frame installation.

If you’re unsure which window installation service you should get, your installer should be able to help you out. Typically, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Charleston

EcoWatch reviews are different from other reviews since we assess these companies through a sustainability lens. We have reviewed the top window installers in Charleston mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Charleston, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Charleston.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. 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

Customer feedback is another super important review factor. If most customers don’t have good feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
