New windows offer many benefits for you and your home

  • Fewer drafts: Single-pane windows are often drafty and they are the least energy efficient. New windows are built better to reduce drafts and greatly improve the comfort of your home year-round.
  • Less maintenance: Old painted windows require regular maintenance. New windows made from vinyl or a composite are not only durable, they're also maintenance-free, never need to be painted, and are easier to clean.
  • Reduced noise: New windows can not only reduce the amount of sound entering your home from outside, but they can also reduce the amount of noise that comes out of your house.
  • Energy savings: Replacing your old, drafty single-pane windows with ENERGY STAR® qualified energy-efficient windows can save you as much as $500 annually on heating and cooling costs.
  • Added security: Most new windows are tested for forced entry and are designed with multiple locks to improve safety.
  • Enhanced curb appeal: New windows can improve your home's appearance - inside and out. There are many window styles and trim styles available to complement the architecture of your home and your personal style. If you're thinking about putting your home on the market, new windows are a good selling point.
