Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. If your windows are made of traditional materials, or are outdated or damaged, you could be sending 25-30% of your home's heat or cool air out of them.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during extreme temperatures, but also saving you money and helping the environment.
So if you're building a new home, renovating or replacing your windows in Flowery Branch, you've found the best place to get started.

How Installing Energy-Efficient Windows in Flowery Branch Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 476 pounds.
Estimated Cost of Window Replacement in Flowery Branch
When considering window installation, each company provides varying services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
Although the national average to install a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, like the location of your home, size, type, number of windows, material and more.
It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Flowery Branch home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first step when considering an installation is to think about whether you should get a full-frame or pocket installation.
Full-frame installations require 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 rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're not sure which type of window installation service you should get, your installer should be able to help you out. Typically, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Flowery Branch
The EcoWatch Reviews team is different from most reviewers, as we're examining these companies through a sustainability lens. We've assessed the best window replacement companies in Flowery Branch mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Flowery Branch 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 in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, cost, professionalism, quality of parts, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. On the other hand, 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Flowery Branch's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Flowery Branch window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Flowery Branch, GA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are picture windows, bay windows, double-hung and single-hung windows, transom windows, awning windows, slider windows and casement windows.
Can you install your own windows?
If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or experience, we don't recommend trying it.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, it shouldn't be raining, since rain can make the installation harder.
Should I replace all my windows at once?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
