Strengthen, Seal, and Preserve Your Home’s Original Foundation
Homes across the East Coast were built to last—and many of them rest on beautiful, historic stone foundation walls. But time, moisture, and New England weather can take their toll. Loose mortar, crumbling joints, damp basements, and water intrusion are common issues in older stone foundations.
At Basement Boss, we specialize in renewing and stabilizing old stone walls, with the option to fully waterproof them using our exclusive BossBarrier™ Sealing System—designed to preserve the character of your home while protecting it for decades to come.
The Challenge with Old Stone Foundations
Stone foundations were built long before modern waterproofing methods existed. While incredibly strong, they are naturally porous and rely on mortar joints that deteriorate over time.
Common issues we see in East Coast stone foundations include:
- Crumbling or missing mortar between stones
- Water seepage through joints and voids
- Damp, musty basements and crawl spaces
- Efflorescence and staining on interior walls
- Cold air infiltration and energy loss
Structural instability from long-term moisture exposure
Left untreated, these issues can worsen—leading to mold, interior damage, and compromised structural integrity.
Our Stone Wall Renewal Process
1. Thorough Evaluation & Planning
We begin with a detailed inspection of your stone foundation to assess mortar condition, stone stability, moisture intrusion, and structural concerns. Every stone foundation is unique, and our approach is tailored to your home’s age, construction, and environment.
2. Stone Wall Repointing & Stabilization
We carefully restore deteriorated mortar joints and reinforce loose stones to renew the strength of your foundation while maintaining its original character. This process improves both structural integrity and appearance.
3. BossBarrier™ Sealing System
For homeowners looking to go beyond restoration, we offer full waterproofing using our BossBarrier™ Sealing System.
BossBarrier™ is a high-performance sealing system engineered to:
- Penetrate deep into porous stone and mortar
- Seal voids and pathways where water and vapor travel
- Create a permanent internal moisture barrier
- Strengthen the wall from the inside without altering its historic look
Unlike surface coatings or temporary patches, BossBarrier™ becomes part of the foundation—providing long-term protection against groundwater, humidity, and seasonal freeze–thaw cycles.
