How Installing Energy-Efficient Windows in Harleysville Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Better temperature control in your home: Energy-efficient windows can cut back on the amount of cool air lost through your windows when cooling your home.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
- Better temperature control in your home: When you live in a city like Harleysville where the winters can get very cold, you often need to rely on your heater to keep your home warm. Energy-efficient windows can decrease how hard your heater needs to work to heat your home.
Estimated Cost of Window Replacement in Harleysville
Each window installation company provides various services and has different costs based on a few factors.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. Costs will differ significantly based on the quality of your products, your location, the current condition of your home and the number of windows you need. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $312 a year on your energy bills in Harleysville.
We recommend requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you're unsure which type of window installation service you should get, your installer should be able to help you out. In general, the decision depends 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 Harleysville
In our hunt to make your home improvements easier and more eco-friendly in Harleysville, EcoWatch chose the above companies as the top window installation companies in the city. We have evaluated the best window installation companies in Harleysville mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. 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
Since this is a guide for Harleysville, we only included companies that serve the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Harleysville.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the highest 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
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Harleysville's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Harleysville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Harleysville, PA Window Replacement FAQs
How much does a window install cost?
The national average cost to replace a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
Unless you have home repair skills and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single 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.
How long does it take to install windows?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
