If you live in an older home and you have the original windows, then you most likely have had thoughts on repairing or replacing them. You may remember the saying "throwing good money after bad".....well this certainly can apply to your approach to windows and doors.
Whether you are contemplating repairing or replacing your windows, call in experts and make sure you get at least 3 opinions or estimates. Beware of the quick fix, which in most cases just adds to the overall cost in the long run. Typically your first clue that there is a problem is a draft coming around or through your windows and doors. If you contact a specialist in the replacement window and door market, they should be able to tell you upon visual inspection whether or not the old windows are worth saving.

When you have your quotes, narrow them down to two options. At this point, it is imperative you physically go to the prospective showroom or factory and see what you are getting for the dollar. Pay special attention to the weatherstripping and the overall frame structure, as well as the hardware. The locking system is critical not only to security, but also to how well the window will seal to keep the elements out.
Glass makes up to 85% of the overall window, and is especially important. There are many tinted glass options available, but the best bang for your long-term dollar is to go with glass called "Low-E, Argon gas & super spacer." This is short for low emissivity, a microscopic metallic oxide spray (almost invisible) that
