The Problem: Why Somerville Foundations Fail


Most local foundations were built using lime mortar, which is naturally breathable. Over a century of exposure to New England's groundwater causes the lime bonding agents to wash away, leading to:

  • Sandy, Crumbling Mortar: Debris constantly appearing on your basement floor.
  • Infiltration: Liquid water or dampness seeping through stone joints.
  • Efflorescence: White, powdery salt deposits that signal moisture travel.
  • Structural Shifting: Loose stones or spalling bricks that threaten the home's stability.


Our Signature Restoration Process

We don't just cover up the problem; we solve it using time-tested masonry techniques and premium lime-based materials.

1. Accurate Lime Mortar Repointing

We remove the decayed, sandy material and repoint the joints with a specialized lime-fortified mortar. Unlike modern Portland cement—which is too hard and can cause historic stones to crack—our lime mixtures move with your home and allow moisture to evaporate safely.


2. Professional Waterproofing & Parging

Once the stone is stabilized, we apply a multi-layer waterproofing system. This includes a lime-fortified base coat followed by a professional sealant. This process stops stone foundation leaks while improving interior air quality and preventing mold growth.


3. Structural Masonry & Brick Repair

From repairing the blue flagging stone bases to replacing damaged exterior bricks, we ensure your foundation is structurally sound and aesthetically preserved.
