How Installing Energy-Efficient Windows in Marietta Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, including:

• Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 476 pounds per year on average.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
• Protect your investment: If your home is on the older side, your windows are most likely outdated.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 increase the value of your home if you decide to sell.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Marietta

Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you can find from window installers.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. These figures are based on the specifics of your installation, like number of windows, size, the location of your home, material, type and more.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $366 a year on your energy bills in Marietta.

We recommend getting free quotes from several window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. A pocket installation entails installing a new window within the old frame. This means instead of tearing out the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which kind of installation to get, you can consult with your installer and get their recommendation. The choice mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Marietta

EcoWatch differs from most reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Marietta and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Marietta, we only included 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 Marietta.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, professionalism, warranty, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window companies won’t always provide the most 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

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Marietta’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Marietta window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
