Wanting peace of mind, the homeowner contacted Jason Basement Waterproofing to install a code-compliant egress window , After speaking with Katie in the office and After project manager Tim evaluating the space, the team developed a plan to safely add a new egress system while preserving the integrity of the home’s foundation.
The installation process included: • Excavating the exterior area around the foundation wall • Carefully cutting through the concrete foundation • Installing a properly sized egress window • Adding a  sump pump pump system to prevent water buildup • Securing a durable window well with proper grading • Sealing and waterproofing the installation...

The Results 

The project delivered both safety and functionality: • The basement now has a safe emergency exit • The space meets egress code requirements • Natural light significantly improved the basement environment • The homeowner gained peace of mind knowing their children are safer

The homeowner contacted Jamison to properly seal and protect all exterior pipe penetrations. After a full inspection, the team implemented a targeted sealing system designed for durability and weather resistance.

The process included:
Removing old, cracked, and ineffective sealant Cleaning and prepping the penetration areas Installing high-performance weatherproof sealants Reinforcing gaps for a watertight exterior seal .....

By Installing double egress windows allowed the homeowner to legally convert an unfinished basement into two safe, code-compliant bedrooms. The project improved safety, increased living space, and significantly boosted property value, demonstrating the strong return on investment for basement bedroom conversions

Encapsulated and insulated

Inspection Findings

Project Manager Ken McKnight  performed a full inspection of the basement and crawlspace. His findings included:

• High moisture levels throughout the basement
• Damp, humid air in the crawlspace
• Efflorescence and minor wall deterioration in the basement
• Musty odors being drawn into the living space above

These symptoms indicated that both the basement and crawlspace were contributing to ongoing moisture problems throughout the home.

Recommended Solution

Inspection Findings

During a full evaluation, the project manager noted:

• Water trapped inside the hollow cores of the CMU block walls
• Signs of moisture seepage along the perimeter of the basement
• An outdated or insufficient drainage system
• A damp, unconditioned, debris-filled crawlspace
• Elevated humidity levels affecting the home above

Recommended Basement Solution

To properly manage water and protect the foundation, we recommended:

1. Full Basement Drainage System

A complete interior drainage system installed along the basement perimeter to capture water before it enters the living space.

2. Sump Pump Installation

A high-capacity sump pump to efficiently discharge all collected water away from the home.

3. Weep Holes in CMU Block Walls

Weep holes drilled at the base of the block walls to relieve hydrostatic pressure and allow trapped water inside the block cores to drain directly into the new system.

These components work together to keep the basement dry, stable, and protected against future water intrusion.

Recommended Crawlspace Solution

To resolve moisture and air-quality issues in the crawlspace, we proposed a full remediation:

1. Full Clean-Out

Removal of old insulation, debris, and any organic material that could retain moisture or harbor mold.

2. Full Encapsulation

Installation of a durable vapor barrier on the floor and walls to isolate the crawlspace from the damp ground and outside air.

3. Spray Foam Insulation

Spray foam applied to rim joists and selected surfaces to improve energy efficiency, seal air leaks, and prevent humid air from entering.

Results

• Basement remains dry even during heavy rain
• CMU block walls no longer hold or release trapped water
• Crawlspace is clean, sealed, and conditioned
• Home’s humidity levels have stabilized
• Energy efficiency improved due to spray foam insulation
• Overall air quality in the living space significantly improved

By combining a full basement drainage system with weep holes and a high-performance sump pump, followed by a complete crawlspace encapsulation and spray foam upgrade, Jamison Basement Waterproofing delivered a long-term, whole-home moisture solution that protects the structure from the ground up.

Jamison Basement Waterproofing designed a customized waterproofing plan to address the root causes of the moisture problem. Our comprehensive solution included:

• Interior Drainage System: GrateDrain Installation of a sub-floor French drain system to capture and redirect water to a #GrateSump sump pump.
• Sump Pump System: A high-capacity sump pump with a battery backup was installed to automatically remove collected water.
• Vapor Barrier Installation: A #ThermalShield vapor barrier was applied to the basement walls to prevent moisture and mold growth.

One challenge we faced was restoring the crumbling walls, which required the use of wire mesh, often referred to as wire lath, and Portland cement to provide strength, stability, and moisture resistance. This technique was especially important in a home that had experienced significant water damage and where traditional masonry repairs had failed.

To address this, Ryan Bond recommended rough-casting the damaged foundation areas and installing a sump pump along with a French drain drainage system. This solution effectively handled both the structural and moisture issues in the basement. It not only restored the stability and integrity of the basement walls but also helped prevent future water damage, giving the homeowner a cost-effective and lasting fix to the foundation problems.

The end result was a five-star review.

The homeowner understood that finishing a basement without proper waterproofing could expose him to the risk of water damage, particularly in a region prone to heavy rain. To address this concern and ensure the basement would remain dry for years to come, we provided a comprehensive waterproofing system designed to protect the space even during the heaviest rains.

🔹 New Sump Pump with Battery Backup: We installed a state-of-the-art sump pump with battery backup #GrateSump to ensure 24/7 protection, even in the event of a power outage.
🔹 Patent Great Drain System: Our GreatDrain Perimeter Drainage System was installed around the entire basement to intercept and redirect water away from the foundation, preventing any water from entering the basement at the floor wall joint.
🔹 ThermalShield Moisture Vapor Barrier: We applied our advanced Thermal Shield Moisture Vapor Barrier to the walls, which creates an impermeable seal against moisture while also improving energy efficiency and adding some insulation value to the foundation walls.
🔹 WiseAire 100 High-Efficiency Dehumidifier: To maintain optimal humidity levels below 55%, we installed our WiseAire 100 High-Efficiency Dehumidifier, which helps keep the basement air dry and prevents mold growth.
🔹 One Free Year of Maintenance: To ensure everything continues running smoothly, we included one year of free annual maintenance for the sump pump, dehumidifier, and waterproofing system.
