How Installing Energy-Efficient Windows in Tega Cay Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if your home is on the older side.
- Reduce 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.
- Save money on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Tega Cay
Windows come in different shapes and sizes, so costs and services will differ tremendously. 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?
The average cost to replace one window is about $600 but can range from $200 to $1,200. This is because of the fact that the cost of window installations are based 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.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $391 a year on your energy bills in Tega Cay.
Something else that influences the overall cost is the material you select for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering a replacement is to decide whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window without taking out the whole frame, which tends to be cheaper than a full-frame installation.
If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Tega Cay, the choice will mostly depend on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Tega Cay
In our hunt to find the most reliable, eco-friendly window installers in Tega Cay, the EcoWatch Reviews team evaluated dozens of companies before landing on these. Along with energy efficiency, we analyzed several window installers in Tega Cay and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services often plays 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 consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have nice things to say about their service from a certain window installation 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 try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you 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 quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Tega Cay, SC Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost of replacing a window ranges from $450 to $650. There are many factors that influence how much it costs, such as local labor costs, styles and sizes of windows, your property’s location, the materials used in designing the windows, how energy-efficient the windows are and the number of windows.
What are the types of windows?
The most common types of windows for homes are picture windows, double-hung and single-hung windows, awning windows, slider windows, casement windows, transom windows and bay windows.
When do I need to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring the pros. The window installation process is complicated 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 much safer option.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
