Masonry Contractors in Astoria, Queens

Astoria has a large stock of 1920s–1940s brick apartment buildings — 4–6 story walk-ups common throughout the neighborhood. These buildings are in a critical maintenance window, with mortar from this era failing throughout and window lintels commonly showing the stair-step cracking pattern of lintel rust expansion.

Masonry Work in Astoria — Pre-War Apartment Building Specialists

Astoria's pre-war apartment buildings — built primarily between 1920 and 1940 — are at a critical point in their maintenance cycle. The mortar joints in 80-100 year old brick construction are failing throughout. Simultaneously, the ungalvanized steel lintels installed in these buildings are corroding and expanding, causing the distinctive stair-step crack pattern above windows that is visible on many Astoria buildings.

Insurance compliance and DOB violations are the most common call triggers in Astoria. Many property owners in Astoria receive DOB violation notices related to parapet conditions — the pre-war buildings in this neighborhood are exactly the age at which parapet deterioration becomes a compliance issue.

FAQ — Astoria, Queens

These are caused by corroding steel lintels. The 1920s–1940s steel lintels in Astoria apartment buildings were installed without galvanizing. Over time, moisture causes rust, which expands to 8–10 times the original volume and cracks surrounding brick in the stair-step pattern. The fix is lintel replacement with galvanized steel.
