How Installing Energy-Efficient Windows in Upper Nazareth Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential 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.
- Decrease your carbon footprint: In Upper Nazareth, you can cut your indirect greenhouse gas emissions by about 286 pounds per year once you install energy-efficient windows.
Estimated Cost of Window Replacement in Upper Nazareth
When looking into window installation, each company offers different services and costs. Let's look at some typical costs and services.
How Much Do New Windows Cost?
According to our market research, the typical cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which have a higher price tag.
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 Upper Nazareth home can mean 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. The amount of money you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that influences the total cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two types that your provider will have: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
If you're still trying to decide which kind of installation you need, you can ask your provider and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Upper Nazareth
In our search to find the most reliable, eco-friendly window installers in Upper Nazareth, EcoWatch examined many companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
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 right window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, cost, warranty, quality of installation, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Upper Nazareth's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Upper Nazareth window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Upper Nazareth, PA Window Replacement FAQs
How much does window installation cost?
The national average cost to install a window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. 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.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: double-hung and single-hung windows, picture windows, casement windows, transom windows, bay windows, awning windows and slider windows.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
What time of year should I replace my windows?
While you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are usually 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.
