How Installing Energy-Efficient Windows in Harleysville 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:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
Estimated Cost of Window Replacement in Harleysville
Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
According to our market research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But costs will differ considerably based on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Harleysville homeowners $294+ each year after replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with 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?
In regard to window replacements, there are generally two types that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for 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 Harleysville, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Harleysville
EcoWatch reviews differ from most reviews since we look at these companies through a sustainability lens. We have assessed the top window installers in Harleysville primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Harleysville, we gave more points to companies that provide services to the city. There are certainly other 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 choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have good things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Harleysville, PA Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost to replace one window is around $600 but can range from $200 to $1,200, based on several factors. The price is generally dependent on the location of your property, the type and material of the window and the size of the window. Also, keep 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 kinds of windows for homes are awning windows, casement windows, transom windows, bay windows, picture windows, double-hung and single-hung windows and slider windows.
What do window installation companies do?
Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.
How long does it generally take to install windows?
Because a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
