Exterior Basement Waterproofing in Western PA
Exterior waterproofing is the most comprehensive approach to basement water protection. By excavating around your foundation and applying waterproof membranes, drainage boards, and new French drains at the footing level, we create a barrier that prevents water from reaching your basement walls entirely. Exterior waterproofing also includes downspout installation and rerouting to direct rainwater safely away from your foundation - a critical but often overlooked part of keeping your basement dry.
What We Provide
Signs You Need Exterior
If you notice any of these warning signs, contact us for a free inspection.
Water Coming Through Walls (Not Joints)
When water is actively penetrating through the wall material itself rather than the floor-wall joint, exterior waterproofing addresses the problem at its source.
Severe or Multiple Foundation Cracks
When the exterior face of your foundation has significant deterioration or multiple cracks, exterior excavation allows repair from the outside -the most effective approach.
Stone Foundations
Many older homes in Western PA have stone foundations that are porous by nature. Exterior waterproofing with a membrane system is often the best solution for these homes.
How Our Exterior Process Works
Site Assessment & Planning
We evaluate the foundation exterior, grading, downspout routing, and soil conditions to plan the excavation and waterproofing approach.
Excavation
We carefully excavate down to the foundation footing, protecting landscaping and utilities. We work section by section for safety.
Membrane & Drainage Installation
We apply waterproof membrane to the foundation walls, install drainage boards, and lay new French drain pipe at the footing level.
Backfill & Grading
We backfill with clean drainage stone and topsoil, ensuring proper grading away from your foundation. Landscaping is restored.
Exterior Questions Answered
Common questions about our services. Can't find your answer? Call us.
How much does exterior waterproofing cost?
Exterior waterproofing in Western PA typically ranges from $8,000-$25,000+ depending on foundation size, depth, and site conditions. It is more expensive than interior waterproofing due to the excavation involved, but provides the most complete protection.
Will exterior waterproofing damage my landscaping?
Excavation will temporarily disrupt the area immediately adjacent to your foundation. We take care to protect established plants and trees where possible, and we restore grading and basic landscaping as part of every project.
