Professional Basement Waterproofing Services in Philadelphia, PA by Jamison Basement Waterproofing

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. 

Jamison Basement will help you every step of the way in ensuring that you have a dry basement. From the initial consultation to the actual implementation, we take great care in making sure that each step of the job is done right. We are a family-owned-and-operated business that has been serving Pennsylvania for over 25 years now and has received recognition from award-giving organizations such as Angie’s List. 

Jamison Basement Waterproofing's Services in Philadelphia, PA

Our services are designed to keep your home healthy and safe. Here’s a list of some of our popular services in Philadelphia, PA. 

Basement Waterproofing - Jamison Basement is the leading basement waterproofing service provider in Southeastern Pennsylvania. Our systems are designed to be flexible enough to handle all types and sizes of homes. With the kind of weather in Philadelphia and the age of the existing homes, you’ll need a reliable basement waterproofing system to keep your basement dry. We use advanced basement waterproofing technology produced by GrateProducts, the leading basement health technology provider in the US. 

Crawl Space Repair Services - A big portion of the air you breathe comes from the basement and crawlspaces. You want to take as much care of your crawlspaces as much as you do for your basements. Jamison Basement provides complete solutions for keeping your crawlspaces dry including dehumidifier installation and crawlspace encapsulation. 

Sump Pump Installation - Water will naturally flow to your basement, the lowest part of the house. To remove accumulated water, you will have to use sump pumps. We only install the most highly reputable sump pump brands. Aside from that, we make sure that you have reliable battery back-up so your sump pump will work even when there are power outages. This is particularly useful during storms when basement flooding is more likely. 

Radon Gas Testing and Mitigation - Radon is a naturally occurring but dangerous gas that can enter your home through cracks in your foundation walls. It’s an invisible and odorless gas, so you won’t know if there’s radon without the use of specialized tools. Jamison Basement provides radon testing and mitigation services in Philadelphia.

Our experience with Jamison was excellent. When we had them inspect the damage leading to flooding in our basement, they conveyed a sense of urgency regarding our foundation damage and flooding without taking advantage of our stress and vulnerability. We had a third party in this business (with no skin in the game) review their quote and he said it seemed very fair, well thought out, and appropriate for what needed to be done. The work took two days and the Jamison employees left our home in perfect condition.
