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. Thankfully, Jamison Basement Waterproofing offers a complete range of basement waterproofing services to keep Philadelphia homes dry and healthy.

So thankful that this was an easy quick process By James B - Philadelphia, PA

Jamison came to look at our wet basement and provided several options for services that we could receive. It took a few days to finish up, but no water since! So thankful that this was an easy quick process.

Project Manager Tim Pronesti conducted a comprehensive inspection of the client’s basement to assess ongoing moisture concerns. During his evaluation, Tim identified elevated humidity levels and signs of moisture intrusion along the walls and floor.


Based on his findings, Tim recommended a two-part solution:


  1. Installation of a high-volume dehumidifier to continually control humidity and maintain a dry, healthy environment.
  2. Application of a moisture-blocking coating on both the basement walls and floor to prevent water seepage, protect structural materials, and improve overall appearance.



This combined approach not only provides the homeowner with a cleaner, more attractive basement, but also delivers long term protection by reducing moisture levels and helping preserve the integrity of the foundation walls.

If you live in the Philadelphia area and have crumbling basement walls please don't hesitate to reach out to us at Jamison Basement Waterproofing ....
