How Installing Energy-Efficient Windows in South Union Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, such as:
- Better temperature control in your home: When you reside in a place like South Union where the winters can be very cold, you often need to rely on your heater to keep your house warm. Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 467 pounds.
- More efficient energy usage in your home: In South Union where the summers can get quite hot, energy-efficient windows lower how much cool air is lost through your windows, which makes it easier to keep your house cool.
Estimated Cost of Window Replacement in South Union
When considering window installation, each company offers varying services and costs. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Generally, homeowners in South Union can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. Costs will vary significantly depending on your location, the number of windows you need, the current condition of your home and the quality of your products. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your South Union home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the full 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 a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In South Union, the decision will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in South Union
EcoWatch reviews are different from other reviews since we evaluate these companies through a sustainability lens. We have reviewed the best window installers in South Union primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have nice feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
South Union, PA Window Replacement FAQs
What is the average cost to install windows?
The typical cost to replace a single window ranges from $450 to $650. There are several factors that influence how much it costs, such as how energy-efficient the windows are, local labor costs, your property's location, the number of windows, the materials used in designing the windows and styles and sizes of windows.
What are the kinds of windows?
The most common kinds of windows for homes include: slider windows, awning windows, casement windows, double-hung and single-hung windows, bay windows, transom windows and picture windows.
When should I use a window installation company?
Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
