How Installing Energy-Efficient Windows in Mullins Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to think about making the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save money on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Mullins
Let's take a look at the cost of window installation and the types of services you may need for your home.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range from $200 to $1,200. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.
It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Mullins homeowners $398+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
Generally, there are two types of window installation services you can get: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which kind of installation you should get, you can talk to your installer and get their advice. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Mullins
In our search to make your home improvements easier and more eco-friendly in Mullins, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Mullins and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Mullins area so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Mullins' climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Mullins window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Mullins, SC Window Replacement FAQs
How much does a window install cost?
The national average cost to install a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes include: casement windows, double-hung and single-hung windows, picture windows, awning windows, bay windows, transom windows and slider windows.
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 ensure 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 usually take to install windows?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
Should I replace all my windows at once?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
