How Installing Energy-Efficient Windows in Simpsonville Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Simpsonville, that's about 415 pounds per year on average.
- More efficient energy use in your home: Because the summers can get pretty hot in Simpsonville, homeowners usually depend on their air conditioner a lot. Energy-efficient windows lower how much cool air is lost through your windows, which makes it easier to keep your home cool.
- 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Better temperature control in your home: When you reside in a city like Simpsonville where the winters can get chilly, you often have to rely on your heater to keep your house warm. Energy-efficient windows can decrease how much heat is lost through your windows when heating your home.
Estimated Cost of Window Replacement in Simpsonville
When looking into window installation, each company offers different services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Generally, Simpsonville homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. These estimates vary depending on the specifics of your installation, including material, size, number of windows, the location of your home, type and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Simpsonville homeowners $357+ per year after replacing single-pane windows.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies provide: 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 installers will replace the whole window, including the sill, frame and trim. Pocket installations are on the simpler end and won't carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
Your window replacement company should be able to help you figure out what's best for your needs. In Simpsonville, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Simpsonville
In our hunt to find the most reliable, eco-friendly window installers in Simpsonville, the EcoWatch Reviews team assessed many companies before deciding on these. We have evaluated the best window replacement companies in Simpsonville mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Simpsonville, we only included companies that provide services to the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Simpsonville.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have positive things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
