Everything below is work our own crews do. Most projects need several of them at once.
Brick Repointing & Tuckpointing
Open mortar joints are how most water gets into a masonry wall. We cut back to sound mortar at the right depth, clear the joint out, and repoint with a mix matched to the original. On pre-war and landmark buildings that usually means lime mortar. Put a hard modern portland mix on soft historic brick and the brick becomes the sacrificial material instead of the mortar, which is one of the quickest ways to wreck a facade. We see it more often than we would like.
Brick Replacement & Wall Rebuilding
Brick that has spalled, cracked or worked loose gets cut out and replaced with units matched for size and color. Where a wall is bulging or has lost its bond to the backup, we take it down in controlled sections and rebuild with new ties and anchors. Patching over a structural problem only moves it somewhere else.
Parapet Wall Restoration
A parapet takes weather on both faces, which is why it shows up as an unsafe condition on facade reports more than anything else. We rebuild parapets that are leaning, cracked or open at the joints, reset or replace the coping, and put in proper through-wall flashing and anchorage. The point is a wall that passes the next inspection rather than causing one.
Lintel & Window Sill Replacement
Steel lintels rust, and rusting steel swells. That is what lifts the brick above your windows and leaves the stair-step crack you have probably been looking at for a while. We shore the opening, pull the failed lintel, set new galvanized or coated steel with proper bearing and flashing, then rebuild the brick around it. Worn sills and copings get replaced with units pitched and drip-edged so water sheds away from the wall instead of into it.
Brownstone & Stone Restoration
Stone asks for a different approach than brick. Depending on what we find, that means Dutchman repairs, patching with a color-matched mortar, resetting stones that have shifted, or replacing units too far gone to save. We also do stoops, entryways and cornices, which take more abuse than anything else on a row house.
Stucco & Cement Coating Repair
We sound the wall, cut the drummy and delaminated stucco back to solid substrate, and rebuild it in proper coats. Then we deal with whatever caused it, which is usually substrate movement or a water path nobody addressed the first time around. The finish gets matched to the existing texture.
Waterproofing, Caulking & Sealants
Restoration without water management is a temporary repair. We replace failed perimeter and joint sealants, repair through-wall and window flashing, and sort out the roof-to-wall and coping details. Where a breathable water repellent makes sense, we will use one. Keeping water out of the assembly is what makes the masonry work last.
Concrete & Structural Repair
Spalling balconies, slab edges, terraces and garage decks get chipped back past the corrosion, the reinforcement cleaned or replaced, and the section rebuilt with repair mortar or placed concrete. Anything load-bearing we coordinate with the engineer of record and file properly.
Facade Cleaning & Coating Removal
Soiling, carbon staining, efflorescence, graffiti, and old elastomeric coatings that are sealing moisture into the wall. We use the gentlest method that actually works, starting with low-pressure water and going further only if we have to. Test panels first, always. Aggressive cleaning on soft historic masonry does damage you cannot undo.
Chimney & Rooftop Masonry
Chimneys and bulkheads are exposed on every face, so they tend to fail first. We rebuild them, replace crowns and caps, reline where it is needed, and repair the flashing and counterflashing where they meet the roof.
