How Installing Energy-Efficient Windows in Plum Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could benefit you:
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Plum
Windows come in various shapes, purposes and styles, so costs and services will differ remarkably depending on several factors. Below, we describe the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Though the average cost to replace a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, including size, number of windows, type, the location of your home, material and more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Plum homeowners $313+ per year after replacing single-pane windows.
Something else that affects the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer 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 when considering a window installation is to think about whether you need a full-frame or pocket installation.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In Plum, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Plum
EcoWatch is different from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Plum and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers 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 not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive things to say about their service from a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Plum’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Plum window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Plum, PA Window Replacement FAQs
How much does window installation cost?
The typical cost to replace one window ranges from $450 to $650. There are several factors that affect the price, such as the number of windows, how energy-efficient the windows are, your property’s location, styles and sizes of windows, the materials used in designing the windows and local labor costs.
What are the most common kinds of replacement windows?
There are various types of windows you can get for your home, including casement windows, slider windows, picture windows, double-hung and single-hung windows, transom windows, awning windows and bay windows.
What do window installers do?
Window installation professionals go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
When is it time to replace your windows?
Windows generally have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have them looked at by an expert to determine if they are in need of a repair or replacement.
