About Us

Reliable Window Lintel Repair Specialist in Brooklyn

The most common mistake we see on Brooklyn row houses is repointing the cracked brick above a window without touching the lintel underneath it. The steel keeps corroding, keeps expanding, and the same crack reopens in two or three winters.

We diagnose what is actually driving the movement, then repair the cause and the damage together.

  • Licensed and insured Brooklyn crews
  • NYC code-compliant lintel and facade repair
  • Free inspection and written estimate
  • Experience with brownstone, pre-war, and modern buildings

Don't Let Lintel Damage Reach the Facade

Rust expands with real force. It lifts brick courses, opens joints, and gives water a path deeper into the wall every season it goes untreated. If you have been searching for lintel repair in Brooklyn, contact Sky Grid Group NY for a free estimate and permit handling.

Why Choose Us

Top-Rated Contractor for Window Lintel Repair in Brooklyn

Many Brooklyn row houses use brownstone or bluestone lintels rather than exposed steel, and those fail by cracking and delaminating instead of rusting. In designated historic districts covering Park Slope, Brooklyn Heights, Fort Greene, Cobble Hill, and Clinton Hill, replacing a visible lintel generally requires Landmarks Preservation Commission review, and the replacement is expected to match the original profile and material.

Access on Attached Lots

On a Brooklyn block with no side yard, the question is how you reach a third-floor window opening at all. We plan scaffold or lift access up front, coordinate with neighbors where the work sits near the property line, and keep the site contained on a narrow frontage.

Repair and Rebuild in One Scope

Replacing a lintel almost always means rebuilding the brick or stone it displaced. We handle both, matching mortar color and joint profile so the repaired section blends into the facade rather than standing out as a patch above the window.

Common Questions About Brooklyn Lintel Repair

Stair-step cracking in the brick above a window or door, rust staining running down the facade, and visible sag or bowing in the masonry above the opening. Rust jacking, where expanding corrosion pushes bricks out of line, is the clearest indicator on older steel. Cracks wider than about a quarter inch, displaced brick, or water around the window frame all warrant an inspection.
It depends on how far corrosion has gone. Surface rust can often be treated, primed, and sealed. Once rust jacking has cracked or displaced surrounding brick, or the steel has lost section, replacement is the correct call.
Yes. Brownstone and bluestone lintels crack and delaminate rather than rust, and masonry lintel replacement Brooklyn row houses need has to match the original stone profile, especially in landmarked districts.
Yes, and we recommend it. Replacing the steel without rebuilding the masonry it damaged leaves the repair sitting under compromised brick.
Yes. Where a visible lintel is being replaced in a historic district, we prepare the submissions and match approved materials and profiles.
