• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Northampton

Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

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

Another factor that affects the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because 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?

The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installation company can recommend the best type for your project. In Northampton, the choice will mostly depend on how much damage there is currently and how old your existing frames are.
