November 12, 2016 | Phoenixville, PA

The challenges we faced were that the basement was in the middle of being finished, so we had to work around the finished materials that were already installed. Also, the floor was thick, which made the jackhammering take a little longer.

To address this, Project Manager Steve C. went out and met with Vinny’s wife and gave her multiple options on how they could protect their investment. She mentioned to Steve that she had just replaced her sump pump, so that was fine, and that they only needed an efficient drainage system on two walls. Based on that, we installed a Grate-Drain drainage system on two walls that drains into their existing sump pump, along with one window well drain. Because they were in the middle of finishing the basement, we were also able to get the job installed as soon as possible. Now they have a lifetime warranty on groundwater seepage and can finish the rest of the basement.

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.

Project Manager Ken McKnight conducted a thorough assessment and recommended a comprehensive crawl space encapsulation system to address the moisture issues and protect the home’s foundation. Challenges Identified • Excessive Moisture: The crawl space had high humidity levels, which were causing the space to become damp and mold-prone. • Poor Air Quality: The trapped moisture was contributing to musty odors in the home and deteriorating indoor air quality. • Risk of Structural Damage: Prolonged exposure to moisture could lead to mold, wood rot, and damage to the foundation, insulation, and flooring. Solution: A Comprehensive Crawl Space Encapsulation System Ken McKnight and the team devised a tailored solution that included a series of steps to eliminate moisture, improve air quality, and protect the home’s foundation for the long term. 1. Crawl Space Cleanout: The first step was to thoroughly clean out the crawl space, removing debris, organic material, and any existing damaged insulation. This created a clean slate and helped eliminate potential mold growth sources. 2. Installation of a New Sump Pump: Next, we installed a high-quality sump pump designed to collect and remove any water that might seep into the crawl space. The GrateSump pump ensures that any future moisture is efficiently pumped out, preventing it from accumulating and causing damage. 3. Sealing with a Moisture Vapor Barrier: To prevent water from infiltrating the space from the soil, we installed a heavy-duty moisture vapor barrier across the entire crawl space floor and walls. The barrier is airtight and waterproof, effectively sealing off any potential moisture intrusion. 4. High-Volume Dehumidifier #WiseAire To maintain a dry and controlled environment, we added a high-volume dehumidifier that continuously removes excess moisture from the air. This ensures the humidity levels are kept at an optimal level, preventing mold and mildew growth. Ongoing Maintenance for Long-Term Protection In addition to the encapsulation, the homeowners now have peace of mind knowing that their crawl space is backed by 3 years of annual maintenance. This includes: • Annual Inspections: Our team will return each year to inspect the crawl space to ensure everything is functioning properly. • Dehumidifier and Sump Pump Servicing: We will service the dehumidifier and sump pump during each inspection to ensure they are operating at peak efficiency. • Ongoing Protection: The annual maintenance program provides the homeowners with ongoing protection against moisture, mold, and potential structural damage. Results: A Dry, Healthy Crawl Space After the project was completed, the homeowners immediately noticed several key improvements: • Eliminated Musty Odors: With the crawl space sealed and moisture under control, the musty odors that had once infiltrated the home disappeared. • Improved Air Quality: The home’s indoor air quality improved significantly as a result of the reduced moisture and humidity. • Protected Foundation: The foundation, insulation, and wooden supports were now safe from the damaging effects of moisture, ensuring the home’s long-term structural integrity. • Peace of Mind: With our annual maintenance program in place, the homeowners felt confident that their crawl space would remain dry, healthy, and protected for years to come. This crawl space encapsulation project not only solved the homeowner’s immediate moisture problems but also provided long-term protection against future issues. By addressing the source of moisture and installing a comprehensive system that included a sump pump, vapor barrier, and dehumidifier, we ensured the home would stay dry, mold-free, and comfortable. With our ongoing maintenance program, the homeowners now have peace of mind knowing that their crawl space will continue to operate efficiently and protect the home. If you’re dealing with moisture issues in your crawl space or want to protect your home from the damaging effects of excess humidity, Jamison Basement Waterproofing can help.

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.
