How Installing Energy-Efficient Windows in Upper Nazareth Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, such as:
- Better temperature control in your home: Energy-efficient windows can lower how hard your AC needs to work to cool your home.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Upper Nazareth, that's about 286 pounds per year on average.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Better temperature control in your home: Energy-efficient windows can lower how hard your heating system needs to work to heat your home.
Estimated Cost of Window Replacement in Upper Nazareth
Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
Generally, homeowners in Upper Nazareth can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. This is because window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Requesting free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're not sure which window installation service you need, your installer can assist you. Typically, 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 Upper Nazareth
EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Upper Nazareth, we only included companies that serve 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 Upper Nazareth.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has gotten tons 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 experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a spectrum 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
Because of Upper Nazareth's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Upper Nazareth window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
