Window Replacement in Allentown
As an Allentown homeowner, you're likely no stranger to the challenges that come with a mixed humid climate. While the area enjoys mild winters, spring showers can be intense, bringing severe thunderstorms and tornadoes that can cause significant damage to your home. In particular, homeowners in Allentown need to contend with leaf and gutter clogging in the fall, which can lead to costly repairs if not addressed promptly.
One of the most significant risks for Allentown residents is foundation settling due to dry falls, followed by severe weather events that bring moisture back into play. This can shift the foundation, leading to cracks and other issues down the line. Replacing old windows with modern energy-efficient units can help mitigate some of these risks, particularly in terms of reducing heat loss and preventing moisture-related problems.
Given the median home age of 1954, many Allentown homes have original windows that are no longer energy-efficient or safe. In fact, according to data from the US Census Bureau, over 77% of households in Allentown own their homes, with a median value of $397,100. With such high property values at stake, investing in window replacement can be a wise decision for homeowners looking to improve both comfort and resale value.
