How Installing Energy-Efficient Windows in Carlisle Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save money on electricity bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
- Reduce your carbon footprint: In Carlisle, you can lower your indirect greenhouse gas emissions by about 286 pounds per year after you install energy-efficient windows.
Estimated Cost of Window Replacement in Carlisle
Let’s take a look at the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Even though the national average cost of installing one window is around $600, it can range anywhere from $200 to $1,200. This is because 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 replace, as well as where your property is located.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Carlisle homeowners $310+ a year after replacing single-pane windows.
Getting free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step of a window installation is to think about whether you need a full-frame or pocket installation.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its 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.
If you’re still trying to decide which kind of installation you need, you can consult with your provider and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Carlisle
EcoWatch reviews are different from other reviews because we evaluate these companies through a sustainability lens. We have assessed the best window installation companies in Carlisle mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
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 best 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 installer in our guide to make sure 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 super important review factor is customer feedback. If most customers don’t have nice things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies won’t always provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is well 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 installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Carlisle, PA Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of replacing a window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
A window’s energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you’re handy and have the tools needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows 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 safer alternative.
How often do you need to replace windows?
Windows generally have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have them checked by an expert to determine if they are in need of a repair or replacement.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
