Devon, PA is widely recognized for its equestrian tradition, beautiful Main Line homes, and highly regarded school systems that make the area one of Chester County's most desirable communities. While Devon offers an upscale suburban atmosphere and historic charm, homes throughout the area can still develop basement moisture problems and foundation concerns over time due to shifting soil, aging structural materials, and changing seasonal weather conditions.

At Jamison Basement Waterproofing, we provide customized waterproofing and foundation repair services designed specifically for Devon homeowners. Damp basements, water intrusion, elevated humidity levels, and foundation settlement are often caused by hydrostatic pressure, poor drainage around the property, or weakened foundation walls. Our team performs thorough inspections to identify the underlying source of the issue and installs dependable waterproofing systems built to provide long-term protection for the home.

Homes in Devon experience humid summers, freezing winter temperatures, and regular rain and snowfall throughout the year. These seasonal weather patterns can cause the soil surrounding the foundation to expand and contract repeatedly, placing stress on basement walls and concrete floors. If moisture issues are not properly addressed, they can eventually contribute to foundation cracks, mold and mildew growth, musty odors, wood rot, and structural deterioration.

Our experienced waterproofing professionals offer a complete range of services including sump pump installation, interior drainage systems, crawl space encapsulation, exterior waterproofing, moisture control systems, foundation crack repair, and structural stabilization solutions. Every project is tailored to the specific condition and layout of the property to help ensure reliable, long-lasting results.

For more than 35 years, Jamison Basement Waterproofing has helped homeowners throughout the region maintain dry, healthy, and structurally sound homes. As a family-owned and operated company, we are committed to delivering honest recommendations, quality workmanship, and dependable customer care backed by decades of basement waterproofing and foundation repair experience.

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 Devon 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.

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 Devon.

We provided the Berwyn homeowner with a new GrateSump liner and a FastSump 1/3hp pump. We ran the discharge out through the foundation wall and connected into a 20 foot underground line so the water drains away from the foundation.

Jamison Basement Waterproofing installed a full perimeter Grate -Drain (Closed) DrInage System to protect all 142 linear feet of their basement from water intrusion. Also installed was the patented freeze stop system which will prevent their basement from flooding should the exterior pipes ever freeze up in the winter time , The homeowners were also concerned about what would happen should a hurricane or other extreme weather event happen in the area again. To ensure that the basement would never flood even during power outages, Jamison Basement Waterproofing installed 2 sump pump which has a battery Inverter for 24-hr protection . Dave the Project manager also recommended several Inspection ports so that the homeowners could move their high volume dehumidifier from location to location without ever having to empty the water and to make inspection of their system in the future very easy for future annual service. Crew Foremen : Steven Custus and crew went over and behind to wow this client.

The basement wall crack had an active leak for some time, so it took a little longer to stop the crack from leaking, especially because it had rained just a day before the installation.

To address this, we replaced the existing sump pump that had burned out with a new Fast Sump. We also repaired the leaking foundation wall crack. Now the homeowners can put their home on the market without the fear of losing resale value due to basement waterproofing issues.

Full thermal shield/ Grate-Drain Drainage system

June 13, 2017 | Villanova, PA

The challenge we faced was having to start this job almost immediately because the basement waterproofing issues were holding up the new home renovations. Our project manager and production manager worked together and were able to have a full crew ready to go within 24 hours.

To address this, Steve Custus designed a full closed perimeter drainage system (Grate-Drain) with inspection ports strategically placed throughout the system for easy access and inspection. We also installed 2 Grate Sumps with 1/3 HP Fast Sumps that can remove 2400 gallons of water per hour. Additionally, we installed a full ThermalShield sealed vapor barrier on the walls to prevent any future wall leaks or dampness from reaching the basement floor, along with a high-volume, high-efficiency dehumidifier that can remove up to 90 pints of moisture a day from the basement air, creating a healthy environment for many years to come.

We also installed a new Grate Sump and closed up the open vents and installed spray foam insulation in the outside cavitys of the rim joist . Now the homeowners can put their home back on the market without the dirt crawlspace taking away from the value of the home ...

September 29, 2016 | Newtown square, PA

The challenge we faced was that it was a pretty tough pump dig, but besides that, everything went smoothly.

To address this, we installed a Grate Sump with an airtight lid, a 1/3 horsepower Fast Sump, and a built-in pump stand to capture groundwater seepage, with the discharge line running to the back of the yard.

Kathy W

May 24, 2017 | Havertown, PA

The challenges we faced were having to get this job done as soon as possible so the property owners would not lose any other deals due to the wet basement.

Because of the recent rain, our Project Manager and the property owner were able to see which corner of the basement the water was seeping into and come up with a quick fix to get the home back on the market. He proposed a new Grate Sump with a partial GrateDrain drainage system to guarantee that the basement stays dry in the area we treated, and the solution is transferable to the next homeowners.

Within two days, the property owner and realtor were able to get the house back listed now that the basement waterproofing issue had been solved.
