Stone Mountain Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Stone Mountain, GA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Stone Mountain Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, such as:

  • Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $362 a year on your bills.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Better temperature control in your home: Energy-efficient windows can decrease how hard your heating system needs to work to heat your home.

Estimated Cost of Window Replacement in Stone Mountain

Each window installer provides various services and has different prices based on a few factors.

How Much Do New Windows Cost?

On average, homeowners in Stone Mountain can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These estimates vary depending on specific characteristics of your installation, like type, number of windows, the location of your home, material, size and more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, 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 cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step when planning a replacement is to think about whether you want a full-frame or pocket installation.

A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the frame that's already there. So, instead of tearing out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should be able to help you decide what's best for your needs. In Stone Mountain, the decision will mostly be based on how old your windows are and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Stone Mountain

In our hunt to make your home improvements easier and more eco-friendly in Stone Mountain, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:

Service Area

Since this is a guide for Stone Mountain, we only included companies that provide services to the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Stone Mountain.

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 in our guide to make sure its technicians 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 customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of installation, quality of parts, professionalism, warranty and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, 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 to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) 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 will earn higher rankings by our standards. We like to see at least ten years of experience.

Stone Mountain, GA Window Replacement FAQs

How much does a window install cost?

The typical cost to install a single window can range between $450 and $650. There are many factors that affect how much it costs, which include local labor costs, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, the number of windows and your property's location.

What type 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 are more efficient than windows that do. To be sure you're getting 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.

When should I use a window installation company?

You should use a window installation professional whenever you want to replace your windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best left to the professionals.

How often should you replace windows?

Windows generally have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
