Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. When it's the middle of summer, your old and leaky windows could be making your home harder to cool and costing you more in power bills.

That's also bad for the environment because the extra energy required by old windows increases your carbon footprint.

Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Lilburn Saves You Money

When you switch to energy-efficient windows, you may see some perks, including:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save on electricity bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
  • Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Lilburn

When considering window installation, each company offers varying services and prices. Let's look at some average costs and services.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range from $200 to $1,200. But costs vary considerably based 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 will make your project cost more.

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

We advise requesting free quotes from several window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

When it comes to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation means replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

If you're unsure which type of window installation service you need, your installer can advise you. Typically, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lilburn

EcoWatch reviews are different from most reviews since we're examining these companies through a sustainability lens. We have evaluated the best window installation companies in Lilburn mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. 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, quality of installation, quality of parts, cost, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that offer 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 years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Lilburn, GA Window Replacement FAQs

How much should window installation cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which type of window should I get?

A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

When should I use a window installation company?

You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a involved process that can take a lot of time, so it's best handled by the professionals.

What time of year is a good time to replace my windows?

While you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, the weather should be dry, as rain can make the installation harder.

When is it time to replace your windows?

Windows generally last 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 are in need of a repair or replacement.
