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

When you upgrade to energy-efficient windows, you may see several perks, such as:

  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on power bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save around $343 annually on your energy bills in Mountain Park.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Mountain Park

Windows come in varying shapes, purposes and styles, so costs and services will vary considerably based on several factors. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

According to our market research, the typical cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. These numbers vary depending on the specifics of your installation, including the location of your home, type, size, material, number of windows and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mountain Park homeowners $343+ a year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also offer 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 question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation entails installing a new window without replacing the frame. This means instead of taking out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Mountain Park, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Mountain Park

EcoWatch reviews are different from most reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Mountain Park and ranked them based on the following methodology:

Service Area

Since this is a guide for Mountain Park, we gave more points to companies that serve the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Mountain Park.

Work Quality

When it comes to 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 give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

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

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

Years of Experience

Due to Mountain Park’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Mountain Park window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Mountain Park, GA Window Replacement FAQs

What is the typical cost to replace windows in a home?

The national average cost of replacing a single window is about $600 but can range from $200 to $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, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the types of windows?

The most common types of windows for homes include: picture windows, bay windows, awning windows, casement windows, transom windows, double-hung and single-hung windows and slider windows.

Can I install my own windows?

If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. But if you don’t have the time or skills, we recommend hiring a professional.

What time of year should I replace my windows?

Even though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, the weather should be dry, because rain can make the installation more difficult.
