Bala Cynwyd, PA is known for its beautiful residential neighborhoods, highly regarded Lower Merion School District, scenic outdoor spaces like the Cynwyd Heritage Trail, and a strong sense of community. With its mix of historic and architecturally diverse homes, many properties throughout Bala Cynwyd can experience basement moisture problems and foundation concerns caused by aging construction, changing weather conditions, and shifting ground conditions over time.

At Jamison Basement Waterproofing, we provide customized waterproofing solutions designed specifically for the needs of Bala Cynwyd homeowners. Older foundations, mature landscaping, and seasonal moisture changes can all contribute to basement leaks, humidity buildup, and water intrusion. Our team works to identify the source of the problem and install long-term systems that help keep your basement dry, healthy, and structurally protected.

The Bala Cynwyd area experiences humid summers, cold winters, and regular rain and snowfall throughout the year. Freeze-thaw cycles and aging drainage systems can place added pressure on basement walls and foundations, leading to cracks, damp conditions, mold growth, and musty odors if moisture issues are not properly addressed.

Our experienced waterproofing specialists offer a complete range of basement and foundation services, including interior drainage systems, sump pump installation, exterior waterproofing, crack repair, crawl space moisture control, and foundation stabilization solutions. Every waterproofing plan is customized to the unique layout and condition of your property for dependable, long-lasting protection.

Crawlspaces 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 Bala Cynwyd.

The challenge we faced was finding the source of the leak behind the finished walls.

To address this, Project Manager Steve C. provided the homeowner with a Level 1 Healthy Basement Certificate. This consisted of a partial GrateDrain drainage system and a vapor barrier on the wall. We also installed a dual-chambered GrateSump liner with a single 1/3 HP FastSump pump and a high-water alarm. This solution comes with a lifetime warranty on the walls where we performed the work.

Full Vapor Barrier/ Grate Drain / Grate Sump

We had to remove the finished material to access the foundation walls where the source of the water was.

To address this, we provided the investors with a partial system that would control any water entering the basement from the currently leaking areas. We installed a closed drainage system with an airtight Grate Sump and a vapor barrier on the walls to channel any wall leaks down into the new drainage system.

Now the property owners can refinish the basement, and the tenant will have full use of her basement. Problem solved.

Senior Project Manager Ed Went out to sit down with the clients to hear about all their concerns with their basement. Ed recommend the homeowners reduce the relative humidity in the basement by bring it down below 50% this would make the basement more comfortable and preventing mold growth at the same time . Ed explain how important it is to choose the right size dehumidifier , because of the size of the basement Ed recommended the compact model dehumidifier that covers up to 1700sq . We also closed up the open Sump pit that was humidifing the air with tons of moisture. Last but not least we replaced all the old leaky windows in the basement , because it’s key when trying to condition the air in the basement you keep all outside air out of the space.

Project Manager Ed suggested a full crawl space encapsulation. A crawl space encapsulation is an amazing way to transform your crawl space into a healthy, livable, and dry usable space. The white 16 mil vapor barrier seals and protects the crawl space from outside elements of nature. It helps to reduce energy usage, improve air quality, gets rid of odors, and reduces the presence of mold, bugs, mice and other critters. After discussing the options, the homeowners agreed to move forward with solution. Derek Price crew was on the job to ensure the installation was successful. The homeowners were given peace of mind knowing their home was relieved of the musty odor smells. The homeowners also gained about 300 sq ft of useable storage space ...

We provided the new homeowner with a high quality , high efficient basement dehumidifier that can remove up to 90pints of moisture a day from the basement air . The homeowner also like that fact that they didn't have to dump any buckets the until drain the condensation right into the basement Sump pump .
