How Installing Energy-Efficient Windows in Lilburn Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Lilburn, that’s about 476 pounds per year on average.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Save money on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Lilburn
Windows come in different purposes, shapes and styles, so costs and services will differ greatly depending on your project. Below, we go over the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
According to our market research, the average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. These figures vary based on the specifics of your installation, such as size, type, material, the location of your home, number of windows and more.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lilburn homeowners $343+ a year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, 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 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?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you decide what’s best for your needs. In Lilburn, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Lilburn
EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. We have assessed the best window replacement companies in Lilburn primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best 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 in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have positive things to say about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a spectrum 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 well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
