Many old house aficionados are against getting replacement windows for their homes, preferring to keep everything as original as possible. However, there usually comes a time sooner or later where the realization comes that new windows are for the best. Here is what you should know about window replacement for your old house.

Why Are New Replacement Windows Best For Old Homes?

Not every old house needs new replacement windows, at least not yet. But obviously, they are eventually going to require replacing, as wood decays and glass breaks, and many old homes have windows nearing the end of their lifespan. For the home that has old windows in good shape yet, a window contractor can do an energy assessment on your current windows, and then shore up the caulking, weather-stripping, and storm windows.

But in most cases, old houses need new replacement windows because they are simply to old to work properly and do their job anymore. Here are five signs it's time to replace them:

• The wood has just become too compromised to even work. The windows refuse to open and close. The wood is warped. The sashes and sills are decayed and rotting.
• They show signs of termite infestation or other pest activity.
• Wind and rain are coming in. Your furnace or air conditioner are constantly running.
• The windows are on an upper floor. Old windows that are difficult or impossible to open can be a real hazard in the event of a fire.
• The glass in the window is single pane.

What Are The Frame Choices For Replacement Windows In Old Homes?

Installing new wooden windows to replace your old ones is certainly an option. After all, wood does a good job at stopping heat transfer and lasts a considerably long time for a natural material.

But you do have other choices. Vinyl windows have greatly improved in recent years. Aluminum windows are ideal in coastal climates, especially in hurricane-prone areas. One of the best new choices in replacement windows is fiberglass, such as the popular Infinity windows. They are stronger than any other type of frame, they won't warp or twist, and they can be painted.

What Are The Glass Choices For Replacement Windows In Old Homes?

Almost all replacement windows now consist of a sandwich of energy-efficient glass that are filled with a gas, such as argon or krypton. The gases serve as insulation. Other options include glass that blocks UV rays, good for the southwest or other hot areas, or conversely, glass that harnesses the power of the sun to help passively heat your home in northern climates.
