20 Best Window Companies in Exeter, PA (2025 Reviews)

How Installing Energy-Efficient Windows in Exeter Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:

• Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save $303 a year on your bills.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Exeter, that’s about 286 pounds per year on average.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Exeter

Windows come in different purposes, shapes and styles, so costs and services will vary considerably based on several factors. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $303 a year on your energy bills in Exeter.

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

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

Your window installation company can advise you on the best type for your project. In Exeter, the choice will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
