Preserving Historic NYC Facades with Timeless Masonry Craft.
Expert mortar raking, period-accurate color matching, structural lintel replacement, and limestone coping repair for brownstones, pre-war buildings, and contemporary brick architecture.
Built specifically to withstand New York’s rigorous structural and environmental demands.
New York's pre-war buildings and iconic brownstones face aggressive weathering from freeze-thaw cycles, driving rain, and structural settlement. Defective or spalling mortar joints allow water to seep behind masonry wythes, oxidizing internal structural steel beams and causing extensive internal wall rot. Green Building Construction LLC provides master masonry restoration: mechanically raking deteriorated joints to exact depth, custom-blending lime-rich breathable mortars that match historic LPC formulas, and stabilizing damaged parapets and lintels.

Close-up inspection of mortar joint deterioration, rust jacking behind lintels, and lab mortar matching to ensure proper sand aggregate and color reproduction.
Uniform Joint Raking
Mechanical raking of old mortar to a uniform depth of 3/4-inch without scoring or damaging adjacent historic brick edges.
Multi-Layer Tuckpointing Application
Hand-troweling fresh mortar in thumb-print hard successive layers, struck with authentic concave or historic weathered joint profiles.
Lintel Stabilization & Rust Proofing
Removal of corroded exterior window head lintels, installing primed structural angle iron with continuous self-adhering flashing membranes.
Chemical Wash & Breathable Sealant
Low-pressure acid wash to remove excess mortar residue followed by siloxane silane water repellent application.
