How Installing Energy-Efficient Windows in Middlesex Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:
- Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise 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 makes up about 25-30% of residential energy use. Installing energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Middlesex
Let's go over the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Generally, homeowners in Middlesex can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost you is based on several factors, such as material, number of windows, size, the location of your home, type and more.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
We advise requesting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step of an installation is to decide whether you need 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 considerable rot or deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Middlesex
The EcoWatch Reviews team is different from other reviewers, as we're examining these companies through a sustainability lens. We've assessed the top window installation companies in Middlesex mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Middlesex area so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, warranty, professionalism, cost, 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 providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Middlesex, PA Window Replacement FAQs
How much does a window install cost?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, remember 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?
A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installers do?
Window installation professionals travel to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
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, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are typically 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.
