A window is your home’s opening to the outside world. More than just providing light and “bringing the outdoors in,” windows are critical to the overall energy efficiency of your home.
When your windows don’t seal properly, it can drastically increase your monthly power bill and your use of fossil fuels. One of the most cost-effective and environmentally responsible things you can do in a green remodel is repair or replace leaky windows.
Best Way To Test if You Need To Fix Leaky Windows
A few minutes of detective work could save you a lot of money in heating or cooling bills. If you’re not sure if you have leaky windows, try the candle test. Hold a lighted candle around all areas of the window. If there is any air coming in, the flame will flicker.
If your wood or vinyl windows show signs of air leaking from the outside frame, try filling in the gaps with insulation or sealing it off. These repairs are simple enough you can handle them yourself at very little cost.
When To Consider Residential Window Replacement
How do you determine when it’s time to replace your old windows? Bill and Melissa Kish, owners of Window Installation Specialists of Pittsburgh, Inc., in Irwin, PA, say the following types of windows are ones most likely in need of replacing.
- Single glazed wood and metal windows with marble sills – found in many older homes, these windows are generally to blame for high power bills. They recommend replacing the entire window and removing the marble since it’s a stone that conducts the cold and compromises the efficiency of even the best window.
- Wood windows with ropes or swing casements. These windows have ornate casements, and homeowners typically want to preserve the historical integrity of their home. A reputable company like Window Installation Specialists can combine new energy efficient options while maintaining the old world charm.
What’s New In Replacement Windows?
Green Products – Along with Energy Star rated wood and fiberglass windows, there are newer, greener options available today. Melissa says that wooden windows are a healthy option for your home because wood is naturally a good insulator. On the other hand, vinyl windows come from foam filled, petroleum based products.
New Technology – Replacement windows continue to evolve thanks to new technology. With double (and sometimes triple) panes of glass, outside air can’t penetrate such a barrier to get into your home. Windows with the Energy Star rating have been certified to exceed the government standard for window efficiency.
Tax Incentives – New tax credits are making replacement windows more attractive than ever. Find out what incentives are available in your area.
What To Look For When Installing Replacement Windows
Finding a qualified replacement window professional is important to having a successful green window remodel. Melissa offers these tips to get you on the right track.
- Make sure your contractor is in good standing by checking consumer organizations like the Better Business Bureau (BBB) and Angie’s List.
- Check your contractor’s insurance for workmens compensation and general liability.
- Call the references they provide. Try to find customers from a few years back to make sure they are still satisfied with their window replacements.
- Ask if your contractor has trade certifications like Installation Master or Pella PCC.
