How Installing Energy-Efficient Windows in Greer Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: Decreasing 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 Greer
When researching window installation, each company provides varying services and prices. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Though the typical cost of installing a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, like the location of your home, material, size, type, number of windows and more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $364 a year on your energy bills in Greer.
Another factor that affects the total cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most 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?
When it comes to window replacements, there are typically two kinds that your installer will offer: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re not sure which kind of window installation service you should get, your installer should be able to assist you. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Greer
EcoWatch is different from most reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them 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
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a spectrum 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 make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Greer, SC Window Replacement FAQs
How much should window installation cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind 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 kinds of replacement windows?
The most common types of windows for homes are picture windows, bay windows, awning windows, casement windows, double-hung and single-hung windows, slider windows and transom windows.
What services do window replacement companies do?
Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
How long does window installation usually take?
Since a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.
