How Installing Energy-Efficient Windows in Hartwell Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- More efficient energy use in your home: In Hartwell where the winters can be very chilly, energy-efficient windows lower how much heat is lost through your windows, which makes it easier to keep your home warm.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Hartwell
When considering window installation, each company provides different services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Though the national average of installing one window is around $600, it can range from $200 to $1,200. This is due to the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
It's important to keep in mind 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 Hartwell homeowners $364+ a year when replacing single-pane windows.
Asking for free quotes from several providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are simpler and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In Hartwell, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Hartwell
EcoWatch differs from most reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Hartwell and ranked them based on the following methodology:
Service Area
Because this is a guide for Hartwell, we only included companies that serve the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Hartwell.
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 featured in our guide to make sure its technicians are well-qualified and that the company has received tons 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 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 want to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a considerable 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
Due to Hartwell's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Hartwell window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Hartwell, GA Window Replacement FAQs
How much does a window install cost?
The typical cost of installing a window ranges between $450 and $650. There are a variety of factors that affect how much it costs, which include the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property's location, styles and sizes of windows and the number of windows.
What are the kinds of windows?
There are various kinds of windows you can get for your home, including slider windows, awning windows, casement windows, picture windows, double-hung and single-hung windows, transom windows and bay windows.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer option.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, 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 the house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
