Brownstone Restoration

Brownstone restoration goes beyond standard renovation — it requires understanding original construction methods, period-appropriate materials, and how to integrate modern systems (plumbing, electrical, HVAC) into a structure never designed for them. Troy Construction of NY Inc. approaches every restoration by first assessing what's structurally sound, what needs repair, and what can be preserved versus what needs to meet current building and safety standards.

Benefits & differentiators: nearly 30 years of brownstone-specific restoration experience; one accountable owner-operator on every job; deep familiarity with the approval process unique to historic districts.

  • Initial structural and condition assessment of the full building

  • Coordination with architect (yours or none) on scope and drawings

  • DOB permitting, and LPC approval if the building is landmarked

  • Phased restoration work: structural, mechanical, then finishes

Brownstone Façade Repair

The façade is usually the most protected and most visible part of a brownstone, and after decades of weather exposure it often shows cracked, deteriorated mortar joints, damaged cornices, and worn stoops, original materials and profiles wherever historic preservation rules require it.

Benefits & differentiators: experience matching historic materials and profiles; familiarity with LPC façade requirements; repairs built to actually shed water and resist future deterioration, not just look correct.


Process overview

  • On-site façade inspection for structural and cosmetic damage

  • Material matching for brick, brownstone, and mortar

  • LPC-compliant repair plan where required

  • Final inspection for water-shedding and structural integrity

Masonry and Stonework

From repointing mortar joints to rebuilding sections of a deteriorated party wall, masonry work on a century-old building requires techniques that modern construction rarely uses. Troy Construction of NY Inc's masonry crews understand structural brick and stone repair, repointing, and rebuilding, always assessed first for the underlying structural condition rather than treated as purely cosmetic.

  • Assessment of mortar condition and masonry structural integrity

  • Mortar mix matched to original (critical for older masonry to avoid trapping moisture)

  • Repointing or rebuilding as required

  • Quality check for alignment, drainage, and finish

Process overview

Benefits & differentiators: understanding of why incorrect modern mortar damages old masonry; structural-first assessment approach; experience working on party walls shared between adjoining brownstones.

Structural Repairs

This is one of Troy Construction of NY Inc's core specialties. Brownstones typically 18 to 20 feet wide, with load-bearing party walls shared between neighbors, and many have settled, shifted, or been altered by previous owners over a century or more. Structural repair work includes foundation underpinning, beam and joist reinforcement, party wall stabilization, and corrections to previous renovations that weren't done correctly.

Benefits & differentiators: deep, specialized experience with narrow row-house structural systems; coordination with structural engineers as standard practice; experience correcting past renovations that other contractors mishandled.

Process overview

  • Structural assessment, often in coordination with a structural engineer

  • Engineering review/approval for structural work

  • DOB permitting for structural work

  • Phased structural execution to maintain building stability throughout

  • Final structural inspection and sign-off

A large share of South Brooklyn and Manhattan brownstones sit within designated historic districts, where exterior changes require approval from the NYC Landmarks Preservation Commission (LPC). Troy Construction of NY Inc. has intensive experience navigating this process — knowing what's likely to be approved, what's achievable, and how to plan a renovation that achieves the client's goals within those constraints.
