Basement Waterproofing Services

Philadelphia, PA is the biggest city in Pennsylvania and is also the 6th most populated city in the United States. It has a population of more than 1.5 million as of 2018 estimates. It’s warm and humid in “Philly” during summers and very cold and wet during winters. The city has a high incidence rate of tornadoes and has experienced various extreme weather conditions such as thunderstorm winds, blizzards, floods, tropical storms, hail, ice storms, winter storms, and heavy snow. More than 70% of all homes in Philadelphia were built in 1959 or earlier. This combination of aged homes and extreme weather conditions can make it difficult to maintain a dry basement in Philadelphia.
