Interior / Exterior Waterproofing Systems

We specialize in addressing all areas of your home that can contribute to basement water leakage, saving you the inconvenience and cost of contacting multiple contractors to determine which part of your home may be responsible for the damage.

Crawl Space Solutions

Damp crawl spaces can cause mold to grow and wood to rot, resulting in structural damage. Wet crawl spaces will release harmful airborne mold spores into your home, reducing air quality. We can transform your crawl space into a clean, dry environment that’s an asset rather than a liability to your home.

Sump Pumps & Battery Backups

A good sump pump installation should include a battery backup system in the event of a power outage. Because there are important considerations in terms of different manufacturers, available horse power, pumping capacity, warranty coverage and reliability.

Basement Egress Window Installations

Egress window systems can help transform your basement into a usable, more inviting living space with added light and ventilation. These windows add code-compliant emergency escape routes to your basement – immediately increasing home safety and value.

Humidity & Wet Air Solutions

Poor ventilation, foundation cracks, porous concrete, condensation...Many factors contribute to high basement humidity. Call Jamison Basement Waterproofing to remedy your humid basement before remodeling!

Foundation Repair & Stabilization

Foundations problems are very common in Pennsylvania. Common causes include; expansive soils, poorly compacted backfill soils and poor drainage. If your foundation is settling, you may see foundation cracks, cracked bricks and mortar joints, or separations at windows and doors.
