Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a big impact on home energy conservation. The Department of Energy estimates that heat gained or lost through old or damaged windows could make up around 30% of residential energy climate usage. In Mountain Park, where the energy bills are an average of $44 per month, that's almost $$159 per year wasted.
Installing new, efficient windows on your home can help you save money each month on your power bills — and you can help the environment, too.
Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Mountain Park Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Mountain Park, that's about 476 pounds per year on average.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save $373 a year on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Mountain Park
Windows come in different shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which have a higher price tag.
It's also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your Mountain Park home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from 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?
The first question to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
Full-frame installations involve replacing the whole 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 deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves replacing a window without removing the entire frame, which is usually less expensive than a full-frame installation.
Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Mountain Park
In our hunt to make your home improvements easier and more eco-friendly in Mountain Park, the EcoWatch team examined dozens of companies before settling on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:
Service Area
Since this is a guide for Mountain Park, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Mountain Park.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that have 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 a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Mountain Park, GA Window Replacement FAQs
How much does window installation cost?
The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, bear in mind 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 most energy-efficient?
A window's energy efficiency is affected by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or experience, we recommend getting a professional to do it for you.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn't be raining, as rain can make the installation harder.
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 probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
