Just The Facts

Your home is one of the biggest investments you can make!

  • It is important now more than ever to focus on home improvement projects that will add value and energy efficiency to your home.
  • Most replacement windows are designed for home energy conservation with state of the art and unique materials.

You need to replace your windows when:

  • Your old windows are hard to open or close.
  • There is condensation or fogging between the panes
  • You feel cold or hot air leaks or drafts through the windows and doors
  • Your windows rattle in the wind
  • Your house is always too cold in winter or too hot in summer
  • Your cooling and heating bills are excessive

Once you decide to replace your windows- DO YOUR HOMEWORK!

  • Shopping for windows and doors can be a time consuming task. With every company claiming that their windows are the best, most efficient and lowest cost, you must separate fact from marketing ploys.
  • Choose a company who hires reputable and educated representatives, has a good selection of windows to choose from and has a Showroom!! A showroom is required to be a dealer and sell major brand windows. True dealers do not work out of a small office or home. They must have a showroom to display the manufacturer's products.
