How Installing Energy-Efficient Windows in Simpsonville Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
- Decrease your carbon footprint: In Simpsonville, you can reduce your indirect greenhouse gas emissions by about 415 pounds per year after you install energy-efficient windows.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Simpsonville
Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you’ll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. Costs will vary considerably depending on the quality of your products, the number of windows you need, the current condition of your home and your location. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a replacement is to think about whether you want a full-frame or pocket installation.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the complete window, including the trim, sill and frame. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installation company will be able to help you understand what’s best for your needs. In Simpsonville, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Simpsonville
EcoWatch is different from other reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Simpsonville, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Simpsonville.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including warranty, professionalism, quality of installation, cost, quality of parts and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Simpsonville’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Simpsonville window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Simpsonville, SC Window Replacement FAQs
How much should window installation cost?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, keep 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 are the most common types of replacement windows?
The most common types of windows for homes are picture windows, awning windows, bay windows, casement windows, slider windows, double-hung and single-hung windows and transom windows.
Can you install your own windows?
If you’re handy and know how to replace a window, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend getting a professional to do it for you.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
How long does it usually take to install windows?
Since a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.
