How Installing Energy-Efficient Windows in Lawrenceville Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Lawrenceville, that's about 476 pounds per year on average.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Save money on electricity bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Lawrenceville

Windows come in various purposes, styles and shapes, so costs and services will differ remarkably based on several factors. Below, we detail the typical cost and services that you'll 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 differ 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.

It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Lawrenceville homeowners $371+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the whole 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 rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are simpler and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you're still debating which type of installation you should get, you can ask your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Lawrenceville

The EcoWatch Reviews team is different from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Lawrenceville area 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 installer included in our guide to make sure its contractors are well-qualified and that the company has gotten tons 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 customer satisfaction, weighted by sample size. 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, warranty, cost, quality of parts and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Lawrenceville, GA Window Replacement FAQs

How much should window installation cost?

The average cost to install one window can range from $450 to $650. There are many factors that influence the price, which include the materials used in designing the windows, how energy-efficient the windows are, your property's location, styles and sizes of windows, local labor costs and the number of windows.

Which kind of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

Do you really need to use a window installation company?

You should hire a window installation company whenever you need new windows. Installing windows is a complicated process that can take a lot of time, so it's best handled by the professionals.

How long does window installation take?

Because the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
