One challenge we faced was that the basement was already finished, but it lacked an egress window, which is necessary for safety in case of an emergency. The Jamison team not only had to install a new egress window but also make it look nice by refinishing around it so it would appear as though it had always been there and would not become an eyesore in the newly finished basement.
To address this, our project manager, led by Steve Custus, quickly assessed the situation and designed a comprehensive solution to meet the necessary requirements for both safety and code compliance. We expertly installed a custom egress window to provide a safe, code-compliant exit from the basement. The installation included proper excavation, window well installation, and ensuring the window met Philadelphia’s building code standards. After the window was installed, we coordinated with the local authorities to ensure that the work was up to code and applied for the necessary building permits. Once the work was completed, the investor was able to pass the inspection with flying colors.
Within a few days, the egress window was fully installed, the building passed inspection, and the property was back on the market. The investor was able to sell the home and move forward with the project, thanks to Jamison Basement Waterproofing providing a timely, professional, and code-compliant solution.

The challenge we faced was installing the egress window neatly and cleanly in such a way that we could reinstall the finished wall and make it look like we were never there.
To address this, we installed a new code-compliant egress window and then refinished the wall with new sheetrock, studs, and trim, completing the job from start to finish.

The challenge we faced was the difficult access to the side of the house, where most of the problems were.
To address this, Steve C., who has fixed thousands of crumbling walls in the Philadelphia area, knew exactly what would satisfy this homeowner. His recommendation was to rough-cast the basement walls, which is a process of mechanically fastening wire mesh to the stone walls and then applying two coats of cement.

The challenge we faced was having a large breakout and debris removal because it was a fairly large basement.
To address this, Project Manager Steve Custus went out to meet with the homeowners and provided them with a Level 4 Healthy Basement Certificate, which consists of a nationally backed warranty on the GrateDrain perimeter drainage system, ThermalShield wall vapor barrier for wall protection, and a GrateSump with a battery backup inverter for 24-hour protection.
We will also service the homeowner’s system for free for the first year.

The challenge we faced was having to work in the crawl space of a brand-new addition. This was very difficult because the clients had spent a lot of money and everything was brand new, so we could not get a piece of dirt or dust on anything.
Senior Project Manager Steve Custus, with over 16 years of experience, went out to meet with the builders who built the new addition.
The best solution for this problem was to install the GrateDrain drainage system, a GrateSump sump pump, and a moisture vapor barrier on the crawl space walls.
Foreman Kareem B. and his team performed the installation. The process began with preparation, including protecting all the client’s items and controlling dust. The GrateSump pump pit was the first thing the crew installed, then they moved on to jackhammer the floor around the perimeter of the crawl space. They cleaned the concrete dust from the area and laid a layer of crushed stone down. The GrateDrain drainage system was pitched downhill, connecting to the sump pump pit. After that, fresh cement was poured and leveled around the perimeter to provide a smooth finish.

The challenges we faced were that this was a fairly large commercial job with a lot of moving parts, and sometimes we had to stop work because the business upstairs did not want any noise when clients showed up.
To address this, Steve Custus proposed installing a variety of products to keep Nuri’s crawl space and basement dry. Jamison Basement Waterproofing installed an interior drainage system around the crawl space, 2 high-volume dehumidifiers, full encapsulation, drainage matting to help direct water to the GrateSumps system, and 2 carbon fiber structural crack repairs.
Crew Foreman Lamier R came out to complete the crawl space and basement installation. The process began with installing the drainage system around the perimeter of the crawl space so that any water entering the area, whether running down the crawl space wall or coming up through the ground, would enter the system.
The drainage matting was installed first on the crawl space floor, and its special dimples on the underside help channel water to the GrateSump in the low spot of the crawl space.
For maximum moisture protection, the team also installed 2 high-volume dehumidifiers with discharge lines so the water could empty directly into the sump pits without the need to dump any buckets.
For the basement waterproofing part of the job, we provided the client with a Level 2 Healthy Basement Certificate, which included a full perimeter #GrateDrain drainage system with inspection ports throughout the system. We also drilled weep holes in the block foundation to drain any water in the walls and installed a high-volume dehumidifier to control moisture.

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.

The challenge we faced was trying to waterproof the basement while there was a large amount of water under the basement floor, so we had to set up temporary pumps during the installation.
To address this, we installed a Custom Level 1 Healthy Basement Certificate. This consisted of a sealed full perimeter GrateDrain drainage system with inspection ports throughout the entire system. We also installed a dual-chambered GrateSump liner with a single 1/3 HP FastSump pump and a high-water alarm. This solution will give the homeowner a lifetime warranty against groundwater seepage for the life of the home.

The challenges we faced were extending all the downspouts under the front walkway, which involved having to cut through solid concrete pads.
To address this, Project Manager Steve Custus went out to meet with the new homeowners. Steve explained how a basement leaks and that the first step to having a dry basement is getting all the water away from the foundation by extending all the roof gutters to the rear of the yard and ensuring proper grading. Project Manager Steve and his crew completed this project in about 7 hours, and the impact it will have on the basement will be enormous.

The major challenge we faced was removing concrete for the drainage system in a really tight crawl space.
To address this, 15-year veteran Steve C. determined that because of the large volume of water in the crawl space, the best solution would be to install a Grate-Drain drainage system in the crawl space along with a full FinishShield moisture vapor barrier. Now, with the crawl space completely dry, the homeowners have another 500 square feet of dry usable space for storage.
The job was performed by Lead Foreman Khian C. and crew over the course of two days.
