How Installing Energy-Efficient Windows in Penn Saves You Money

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

• Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
• Save money on energy bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $293 annually on your energy bills in Penn.
• Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 467 pounds per year on average.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Penn

When researching window installation, each company offers varying services and prices. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

Even though the typical cost to replace a single window is about $600, it can range anywhere from $200 to $1,200. But costs will differ considerably depending on the quality of your products, the current condition of your home, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $293 a year on your energy bills in Penn.

We recommend requesting free quotes from several window companies to find the one that works best for your budget.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. Pocket installations are simpler and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installation company can advise you on the best type for your project. In Penn, the choice will mostly be based on the efficiency of your home and how old your existing frames are.
