Replacement Windows

How do new construction and replacement windows differ?

The main difference in new construction and replacement windows is the procedure of installation. New construction windows are installed before siding, which allows the window fins to be directly nailed to the exterior sheeting and framing. A replacement window installation can require:

– Removal of the existing window

– Cutting of siding to expose the window fins

– Exterior trim installed (if siding is cut)

– Interior trim replacement (if necessary)

– Drywall repair (if necessary)

What is the benefit of replacing a window?

Replacing a window can be a big decision. However, window investments provide a great return-on-investment, up to 90%.

Not only can they increase the curb appeal of your home, replacement windows can increase the thermal efficiency of your home – decreasing utility costs. Along with energy efficiency, replacement windows can reduce the sound transmission from external noises. Many newer windows have been designed to add increased security towards forced entry and often come with multiple locking points.

How do I know when it is time to replace a window?

There are more reasons than a broken window pane to replace a window, some not as obvious as others.

Rotting or Deteriorating Casings (Wood)

If the wood on the casings of the window are rotting, it is time to replace the window. Wood rot or dry rot effects the integrity and strength of the wood through decay. A simple test to check if your window casings are rotting is to push a flat-head screwdriver into the wood. If the screwdriver easily penetrated the surface, the wood’s integrity and strength have been compromised.

Compromised Glass Panes

When a window pane is compromised you will see a build up of moisture between the panes. Often, the moisture creates a foggy layer between the window panes. This happens when the glass is chipped/cracked or the sealant around the perimeter of the glass is damaged.

High Utility Bills

According to the U.S. Department of Energy, leaky and inefficient windows, skylights and doors account for up to 25 percent of the average household’s energy bills. Some sources estimate as high as 40 percent.

Broken Glass/Mechanisms

Broken windows and glass is a hazard to your safety and the security of your home. Operating a faulty mechanism, though not as hazardous as a broken pane, can further the damage to the mechanism or cause other damage to the other window components.
