From repointing a crumbling rowhome facade to rebuilding a sinking bluestone stoop, every job goes through the same process: free on-site inspection, written estimate within one business day, and color-matched mortar that holds up for decades.

Pointing, or repointing, is the process of removing deteriorated mortar from the joints in masonry and replacing it with properly matched fresh material. On Philadelphia rowhomes built between 1850 and 1950, the original lime-based mortar starts failing at the surface long before the brick or stone itself shows damage. Done right, repointing seals the wall against water for another 50 to 75 years.
We specialize in pre-war facades where the original mortar profile matters. That means proper joint shape, the right hardness (lime mortar for soft historic brick, not Portland cement that will crack the brick over a decade), and color-matched dye when the homeowner wants the patch invisible.
Signs include: visible cracks running along the joint lines, mortar that crumbles when you scrape it with a screwdriver, gaps between mortar and brick wide enough to slip a coin into, and any sign of water staining or efflorescence on the interior wall. We confirm everything with photos during the on-site inspection.
Lime-based mortar reaches its initial set in 24 to 48 hours and continues to gain strength for up to 12 months. The wall is functionally water-resistant within a day. Avoid pressure washing the new joints for the first 30 days.
Yes. We sample the existing joint with a small extraction, test color-matched mixes against the dry sample, and confirm the match with you before starting the full job. On historic walls we can produce dye-tinted mortar that reads as part of the original wall.
A small facade (one elevation of a rowhome) is usually 2 to 4 days. A full home envelope can run 1 to 2 weeks depending on the height and the condition of the existing joints. We give you a firm timeline in the written estimate.
Brownstone is soft, layered sedimentary stone. The decorative carved details (window lintels, doorway surrounds, cornice work) on historic Philadelphia and Brooklyn brownstones erode at the surface long before the structural stone fails. The damage looks dramatic but is repairable with the right materials.
We are licensed Jahn restoration system applicators. The Jahn system is the industry's gold-standard lime-based repair mortar designed specifically for historic stone restoration. It carves and tools like the original stone, color-matches to the existing wall, and weathers at the same rate, so the patch reads as part of the original facade across decades.
Jahn is a line of pre-formulated lime-based restoration mortars (M70 for general stone, M120 for harder limestone, M30 for soft brownstone) developed by Cathedral Stone Products. It is the industry standard for restoring carved stone on historic landmarks. Becoming a Jahn applicator requires manufacturer certification and a portfolio of completed work.
Quarried stone matching the original is often no longer available, prohibitively expensive to source, or visibly different in tone and weathering. Restoration with Jahn mortar preserves the original stone where intact and rebuilds only the damaged portions. The result reads as the original wall, not a replaced piece.
Properly applied Jahn restoration is rated for 50 to 100 years of weathering, the same as the surrounding original stone. The match is meant to age together with the wall, not stand out as a fresh patch.
Yes. Window lintels, doorway surrounds, cornice work, and carved keystones all restore with the same process. Hand-carving the patch to match the original profile is part of every Jahn restoration job we do.
Most water damage in a Philadelphia rowhome enters at the window perimeters and the lintels (the structural pieces above doors and windows). When the caulking fails, water gets behind the brick and rots the framing inside. When the lintel rusts, it expands and pushes the surrounding masonry apart.
We seal the full window and door perimeters with high-grade urethane caulk rated for 20+ years of exterior weathering, and we replace failing steel or stone lintels before cracks spread to the surrounding facade. The fix is permanent when done right; the temporary patch a handyman quotes you for $200 will fail the next freeze cycle.
Visible rust staining running down the brick below the lintel is the first sign. Step cracks (cracks that follow the mortar joints in a stair-step pattern) above the window are a stronger signal. Any visible bulge in the brick above a window means the lintel has expanded and replacement is urgent.
High-grade urethane caulk holds for 15 to 25 years on a properly prepared surface. Cheaper acrylic-latex caulk (often what a previous contractor used) lasts 3 to 5 years and is what is failing now. We use urethane on every job.
We can produce documentation suitable for an insurance estimator, including photos, scope of work, and the underlying cause. Travis works directly with adjusters when the cause of damage is masonry-related and the homeowner's policy covers it.
Philadelphia rowhome chimneys take more weather abuse than any other part of the building. Crown cracks let water down the flue, failing flashing soaks the framing below, and decades-old brick at the top loosens until a single windstorm puts it on the sidewalk.
We rebuild crowns with a poured concrete cap that sheds water properly, replace step flashing where it has rusted or pulled away from the brick, and rebuild the upper section of the chimney itself when the brick has weathered past repair. The crew is comfortable working at height with proper rigging.
For storm damage we work with insurance estimators and provide the photo documentation and scope they need to authorize the claim.
The crown is the concrete or stone slab at the top of the chimney that sheds water away from the flue and the brick below. When the crown cracks (common after 30+ years), water runs straight down into the chimney structure, freezes, and rapidly destroys the upper brick courses. A proper rebuild lasts 30+ years.
Sometimes. A chimney that has tilted more than a few inches at the top usually needs the upper section taken down and rebuilt from a sound course below the lean. We can assess on site and tell you whether straightening is possible or a partial rebuild is required.
We document the damage with dated photos, write the scope of work, and work directly with the insurance estimator. The homeowner stays the policyholder; we are the licensed contractor performing the repair. We have completed enough storm jobs to know what adjusters need to see.
Failing stone retaining walls in Philadelphia mostly come down to three things: the lime mortar joints have crumbled and the wall is bowing under ground pressure, drainage at the base is clogged and water freezes inside the wall, or individual stones have shifted out and the surrounding mortar is carrying the load. Left alone, any one of those turns into the next.
We repair the wall in place instead of tearing it down. Repointing with lime mortar that flexes with the stone, drainage work at the base where the cause is groundwater, and single-stone resets where stones have fallen out. Full teardown is sometimes the right call for a badly leaning wall, but most of the time targeted repair extends the wall another 50+ years at a fraction of the cost.
Not always. Bowing usually means the mortar joints have failed and the wall is no longer holding the soil load evenly. If the lean is under a few inches at the top, we can often repoint the joints, address drainage behind the wall, and stop the problem from progressing. We assess on site and tell you honestly whether repair is enough.
Usually yes. Single-stone resets use the same lime mortar as the original wall, color-matched to the existing joints. We clean out the cavity, dry-fit the stone, and pack mortar behind so the stone sits firm. The repair is invisible once the joints cure.
Sometimes that is the right call (badly leaning walls, structural cracks running through multiple stones, every joint failing). But most of the time targeted repair is the right answer and costs a fraction of a full rebuild. We will tell you honestly which approach fits your wall.
Every Philadelphia rowhome has a stoop. Bluestone treads, stone or brick risers, an iron rail bolted into the cheek wall. After 100+ winters, the bluestone cracks, the mortar between the risers fails, and the rail works loose. The stoop starts to sink on one side as the base settles.
We repair what's repairable and rebuild what isn't. Cracked top tread? Replace only that piece with color-matched bluestone. Mortar washed out between the risers? Repoint with proper lime mortar. Iron rail flopping in the wind? Re-anchor it into rebuilt masonry. Whole stoop sinking? Pull it apart, rebuild the structural base, reset the bluestone, leave it level for the next century.
Often yes. If the base is still sound and only the visible stone has failed, we can replace individual treads with color-matched bluestone. We confirm on the inspection whether the underlying structure is solid enough for a tread-only repair or whether the cracking is a symptom of deeper movement.
Sometimes. A stoop that has tilted under an inch usually means the front-edge base needs to be reset; we can sometimes lift, shim, and re-mortar without taking the whole thing apart. Past an inch of settle, it is almost always better to rebuild from the footing up so it stays level.
Yes. We reset and re-anchor iron rails into the rebuilt masonry as part of the same job. If the rail itself is corroded past safety, we can coordinate with a metal fabricator to replicate the original profile.
A typical Philly rowhome stoop is 3 to 5 days from teardown to walkable. We start by photographing and salvaging the original bluestone where possible, then rebuild the structural base, reset the treads, repoint the risers, and re-anchor the rail. The stoop stays usable up to the day we start the teardown.
