How Installing Energy-Efficient Windows in Lower Milford Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Lower Milford, that's about 286 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- 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.
Estimated Cost of Window Replacement in Lower Milford
Windows come in varying shapes, styles and purposes, so costs and services will vary greatly based on your project. Below, we describe the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
On average, homeowners in Lower Milford can anticipate that most window installations will cost between $250 and $1,200, with the average cost at around $600. These numbers vary depending on the specifics of your installation, like number of windows, size, type, material, the location of your home and more.
It's also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Lower Milford home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When considering window installations, in general there are two types that your provider will offer: full-frame and pocket installations.
Full-frame installations involve replacing the whole 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 damage. Full-frame installations are more involved and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation you should get, you can talk to your installer and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Lower Milford
EcoWatch reviews are different from other reviews since we evaluate these companies through a sustainability lens. We've assessed the top window replacement companies in Lower Milford mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Lower Milford area so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you choose. 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
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, quality of parts, professionalism, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Lower Milford's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Lower Milford window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Lower Milford, PA Window Replacement FAQs
How much does window installation cost?
The national average cost to install one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows will be 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're getting 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.
Can I install my own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. But if you don't have the time or experience, we recommend hiring a professional.
How long does window installation usually take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, since rain can make the installation more difficult.
