How Installing Energy-Efficient Windows in Flowery Branch Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could help you:
- Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Flowery Branch
Let's take a look at the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. But costs will differ considerably depending on the current condition of your home, the number of windows you need, your location and the quality of your products. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Flowery Branch homeowners $353+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company will be able to help you understand what's best for your needs. In Flowery Branch, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Flowery Branch
In our search to make your home improvements easier and more eco-friendly in Flowery Branch, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We've reviewed the best window installation companies in Flowery Branch primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut 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 self-explanatory, but we've chosen to highlight window installation companies that serve Flowery Branch 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 company featured in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies with 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 a proven track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

What time of year should I replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
When is it time to replace your windows?
Windows generally last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them checked by an expert to determine if they need any repairs or replacements.
