Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Piscataway Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, including:

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: In Piscataway, you can lower your indirect greenhouse gas emissions by about 206 pounds per year once you install energy-efficient windows.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Save money on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.

Estimated Cost of Window Replacement in Piscataway

Windows come in varying shapes and sizes, so costs and services will vary remarkably. Here are the average costs and the primary services that you can find from window installation companies.

How Much Do New Windows Cost?

According to our research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. These amounts vary based on specific characteristics of your installation, like type, material, the location of your home, size, number of windows and more.

It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Piscataway homeowners $306+ a year when replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When it comes to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

Full-frame installations require replacing the full 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 deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within its 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 still trying to decide which kind of installation to get, you can ask your installer and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Piscataway

In our hunt to find the most reliable, eco-friendly window installers in Piscataway, the EcoWatch Reviews team examined dozens of companies before landing on these. We have assessed the best window installation companies in Piscataway mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Piscataway area so you can find the best window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven 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.

Piscataway, NJ Window Replacement FAQs

What is the average cost to install windows?

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

What kind of window is the most energy-efficient?

A window’s energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

Do you really 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. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.

What time of year is a good time to replace my windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

How often do you need to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
