How Installing Energy-Efficient Windows in James Island Saves You Money

Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:

  • Save money on energy bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in James Island

Windows come in varying shapes, styles and purposes, so costs and services will differ considerably depending on several factors. Below, we describe the average cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in James Island can expect that most window installations will range from $250 to $1,200, with the average cost at around $600. But costs will differ significantly depending on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.

It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save James Island homeowners $313+ a year when replacing single-pane windows.

Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. These installations are more involved and will increase the overall cost. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in James Island

EcoWatch is different from other reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality 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 installer featured in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, cost, warranty, quality of installation and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

James Island, SC Window Replacement FAQs

What is the average cost to install windows in a home?

The average cost to install one window ranges between $450 and $650. There are many factors that affect the cost, including how energy-efficient the windows are, local labor costs, your property’s location, styles and sizes of windows, the materials used in designing the windows and the number of windows.

What kind of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.

What do window installation companies do?

Window installation companies will do the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.

How often do you need to replace windows?

Windows usually last 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to see if they need any repairs or replacements.

How long does window installation typically take?

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that have to be installed.
