How Installing Energy-Efficient Windows in Millburn Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:
- Decrease your carbon footprint: In Millburn, you can cut your indirect greenhouse gas emissions by about 206 pounds per year once you install energy-efficient windows.
- Protect your investment: Keeping your windows up to date 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 from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save on power bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save about $283 annually on your energy bills in Millburn.
Estimated Cost of Window Replacement in Millburn
Windows come in varying styles, purposes and shapes, so costs and services will vary considerably based on your project. Below, we go over the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, including material, size, the location of your home, number of windows, type and more.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $283 a year on your energy bills in Millburn.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
Your window installation company will be able to recommend the best type for your project. In Millburn, the choice will mostly depend on the efficiency of your home and the condition of your existing frames.
