How Installing Energy-Efficient Windows in Williamston Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:

  • Save money on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Williamston, that's about 415 pounds per year on average.
  • 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Williamston

When researching window installation, each company offers varying services and prices. Let's go over some typical costs and services.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range from $200 to $1,200. Costs will vary considerably depending on the current condition of your home, your location, the quality of your products and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Williamston homeowners $377+ a year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, although 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 more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the overall cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the frame that's already there. This means instead of taking out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which window installation service you should get, your installer can help you out. In general, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Williamston

EcoWatch differs from other reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Williamston, 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 Williamston.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, quality of parts, quality of installation, professionalism and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that offer 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 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.

Williamston, SC Window Replacement FAQs

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

The national average cost of replacing one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What kind of window is the best for energy efficiency?

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

Do you really need to use a window installation company?

You should hire a window installation company whenever you need to replace your windows. Installing windows is a involved process that can be difficult to do on your own, so it's best handled by the professionals.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, because rain can make the installation more difficult.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to gain that benefit. However, if you have just a few windows that are damaged or drafty, you can replace just those.
