The Problem & Initial Inspection Findings
A two-story commercial building exhibited widespread mortar wash-out, cracked brick piers, rusted steel window lintels, and municipal sidewalk safety violation notices.
Comprehensive Scope of Work
Phased Construction Methodology
1Phase 1: Mortar Analysis & Sampling
Analyzed existing lime-to-sand ratios to formulate an authentic, low-compression mortar that allows the historic brick to breathe and flex.
2Phase 2: Raking & Structural Lintel Prep
Ground joints clean using HEPA-vacuum shrouded grinders to minimize airborne dust. Relieved stress over window openings to coat support steel.
3Phase 3: Deep Joint Repointing
Packed mortar in successive 1/4-inch layers, tooling joints to match the original concave historic profile.
4Phase 4: Wash Down & Protection
Cleaned completed facade with mild detergent wash and applied breathable hydrophobic protective coating.
Engineering Challenges
Managing dust suppression, pedestrian safety, and active ground-floor retail operations along a busy commercial corridor while strictly adhering to municipal environmental noise ordinances.
Final Verified Result
Structural stability restored, violation notices formally dismissed with the Department of Buildings, and complete exterior aesthetic renewal matching the historic neighborhood character.
