Although renewable energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's energy efficiency can also have a large impact on home energy conservation. Poor windows can make your AC or heater work extra hard in the summer or winter.

How Installing Energy-Efficient Windows in Greenville Saves You Money

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

  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: In Greenville, you can lower your indirect greenhouse gas emissions by about 507 pounds per year when you install energy-efficient windows.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Greenville

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 install one window is about $600 but can range anywhere from $200 to $1,200. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $392 a year on your energy bills in Greenville.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

In regard to window installations, in general there are two types that your provider will offer: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to recommend the best type for your project. In Greenville, the decision will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Greenville

EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve Greenville so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a variety 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 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 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.

Greenville, TX Window Replacement FAQs

What is the typical cost to install new windows in a home?

The national average cost to install a window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installers visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.

How long does window installation generally take?

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

Should I replace all my windows at once?

If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
