How Installing Energy-Efficient Windows in Charleston Saves You Money

Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to consider making the switch:

• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Charleston, that's about 763 pounds per year on average.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way.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 property if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Charleston

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

How Much Do New Windows Cost?

According to our research, the national average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. Costs will vary significantly based on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.

Keep in mind that energy-efficient windows may cost more upfront, 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 installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first step when planning a window replacement is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage. Full-frame installations are more involved and will raise the overall cost. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

Your window replacement company will be able to help you understand what's best for your needs. In Charleston, the decision will mostly be based on how old your home is and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Charleston

EcoWatch reviews differ from other reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Charleston and assigned rankings based on the following methodology:

Service Area

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

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer 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 a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
