How Installing Energy-Efficient Windows in Northampton Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help lower that amount, which helps you save $312 a year on your bills.

Estimated Cost of Window Replacement in Northampton

When looking into window installation, each company offers varying services and costs. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Generally, Northampton homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at around $600. Costs will differ significantly based on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Northampton homeowners $312+ each year after replacing single-pane windows.

Getting free quotes from several providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step when considering an installation is to decide whether you should get a full-frame or pocket installation.

Full-frame installations entail replacing the total window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will raise the total cost. A pocket installation involves replacing a window without removing the whole frame, which is usually less expensive than a full-frame installation.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Northampton, the decision will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Northampton

In our hunt to find the most reliable, eco-friendly window installers in Northampton, EcoWatch evaluated dozens of companies before landing on these. Along with energy efficiency, we assessed each installer 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 selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain company, you won’t see it 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 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 give you lengthy warranties for products, parts and installation (aka workmanship) 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.

Northampton, PA Window Replacement FAQs

What is the average cost to install new windows in a home?

The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is usually 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 initially but can save you hundreds of dollars a year in energy bills.

What kind of window is the best for energy efficiency?

A window’s energy efficiency is influenced by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

What services do window replacement companies offer?

Window installers will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.

How long does it usually take to install windows?

Since a window takes about 30 minutes to install, around 16 windows can be installed during an 8-hour work day.
