How Installing Energy-Efficient Windows in Oak Ridge Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could benefit you:
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Oak Ridge
Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
On average, Oak Ridge homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These numbers are based on specific characteristics of your installation, like the location of your home, number of windows, type, size, material and more.
It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Oak Ridge home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that influences the overall cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
Your window replacement company should be able to help you understand what’s best for your needs. In Oak Ridge, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional check on your frames and window sills.
