How Installing Energy-Efficient Windows in Matthews 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:

  • Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • 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 damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Matthews

Each window replacement company offers various services and has varying costs based on several factors.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost varies depending on several factors, including number of windows, size, the location of your home, material, type and more.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Requesting free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

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

How We Choose the Best Window Installers in Matthews

In our hunt to make your home improvements easier and more eco-friendly in Matthews, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Matthews and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Matthews, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Matthews.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, cost, quality of parts, quality of installation, warranty and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that provide 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 installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Matthews, NC Window Replacement FAQs

What is the typical cost to install windows?

The national average cost to replace a window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is typically influenced by 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 upfront but can save you hundreds of dollars a year in energy bills.

Which kind of window is the best?

A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

Do you really have to use a window installation company?

You should use a window installation professional whenever you want new windows. Installing windows is a involved process that can be difficult to do on your own, so it’s best handled by the professionals.

How often should you replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
