How Installing Energy-Efficient Windows in Apex Saves You Money

There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Save on energy bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.
  • Reduce your carbon footprint: In Apex, you can cut your indirect greenhouse gas emissions by about 345 pounds per year when you install energy-efficient windows.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Apex

When considering window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range from $200 to $1,200. These estimates are based on specific characteristics of your installation, such as size, number of windows, material, the location of your home, type and more.

It’s also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that switching out the windows on your Apex home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

The first step of a window installation is to figure out whether you need a full-frame or pocket installation.

Full-frame installations involve replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. These installations are more involved and will increase the total cost. A pocket installation involves installing a new window within the frame that’s already there. This means instead of removing the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which type of window installation service you should get, your installer should be able to help you out. Typically, the choice is based 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 Apex

EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. We’ve evaluated the top window replacement companies in Apex mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Apex, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Apex.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide 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

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installers won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. 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.

Apex, NC Window Replacement FAQs

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

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

What are the different kinds of windows?

There are several different types of windows you can get for your house, such as transom windows, awning windows, picture windows, bay windows, casement windows, double-hung and single-hung windows and slider windows.

What services do window installation companies provide?

Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

How often do you need to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
