How Installing Energy-Efficient Windows in Cranberry Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, such as:

  • Protect your valuables from fading: When you upgrade 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 harmful UV rays.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Cranberry

Let’s take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

On average, Cranberry homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at about $600. How much it will cost depends on several factors, such as the location of your home, type, size, number of windows, material and more.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

We recommend requesting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first step when considering an installation is to figure out whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant damage. Because these installations are more involved, they will increase the total cost. 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 rot or deterioration, you will most likely need a full-frame installation instead.

Your window replacement company will be able to help you figure out what’s best for your needs. In Cranberry, the decision will mostly be based on the age of your home and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Cranberry

In our search to find the most reliable, eco-friendly window installers in Cranberry, the EcoWatch Reviews team assessed dozens of companies before deciding on these. Along with energy efficiency, we assessed several window installers in Cranberry and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

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 service from a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores 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

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Cranberry, PA Window Replacement FAQs

How much should window installation cost?

The typical cost of replacing a single window ranges from $450 to $650. There are several factors that affect the price, which include how energy-efficient the windows are, your property’s location, local labor costs, styles and sizes of windows, the number of windows and the materials used in designing the windows.

Which kind of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.

Do I really need to use a window installation company?

You should hire a window installation professional whenever you need to replace your windows. Installing windows is a complex process that can take a lot of time, so it’s best left to the professionals.

Should I replace all my windows at once?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.

How long does window installation usually take?

Since the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
