How Installing Energy-Efficient Windows in Mullins Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:
- Better temperature control in your home: Living in a chilly place like Mullins can often mean relying on your heater to keep your house cool. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
- More efficient energy usage in your household: Because the summers can get pretty hot in Mullins, homeowners usually rely on their air conditioner a lot. Energy-efficient windows reduce the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 415 pounds.
Estimated Cost of Window Replacement in Mullins
Windows come in all shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, Mullins homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at around $600. But prices 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 companies also provide door installations and replacements, which will make your project cost more.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $398 a year on your energy bills in Mullins.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the total window, including the sill, frame and trim. A pocket installation entails replacing a window without replacing the frame. So, instead of taking out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company should be able to help you understand what's best for your needs. In Mullins, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Mullins
The EcoWatch Reviews team differs from other reviewers because we evaluate these companies through a sustainability lens. We have decided to evaluate the top window installation companies in Mullins mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Mullins' climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Mullins window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Mullins, SC Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it generally take to install windows?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
