Everything above your foundation depends on it staying still. When it does not, the evidence shows up everywhere except the basement first: doors that stop latching, windows that stick, diagonal cracks running from the corners of door frames, gaps opening at baseboards, floors that slope. New Jersey soil is a large part of why. Much of the state sits on dense clay that swells when it absorbs water and shrinks as it dries out, and that seasonal movement pushes on foundation walls and footings from the outside all year long. Add a high water table across a lot of Hudson, Bergen and Middlesex County, plus freeze and thaw cycling down to the frost line every winter, and you get steady pressure on a structure that was never meant to move.
A+ Chimney & Masonry provides foundation repair, crack repair, structural masonry, underpinning, footing repair, wall reinforcement and full or partial foundation rebuilds for homes and businesses across New Jersey. We work on every foundation type common here, including old rubble stone and brick foundations under Jersey City, Hoboken and Newark row homes, concrete block basements, and poured concrete walls in newer construction. Each type fails differently and needs a different repair, which is why we diagnose the cause of the movement before we quote anything. A crack is a symptom. Water, soil pressure, poor drainage, a failed footing or settlement below the footing is the actual problem, and sealing the symptom without fixing the cause just delays the same call by a year or two.
From a single crack repair to full underpinning, we handle every level of foundation work with the same attention to detail.
Foundation Crack Repair
Poured walls get sealed with polyurethane or epoxy injection that fills the crack through the full wall thickness, not just the surface. Block and stone foundations get proper masonry repair, since injection does not work on hollow or irregular units.
Bowing and Bulging Wall Repair
Walls pushing inward are responding to soil pressure and need structural reinforcement, not sealant. We stabilize with carbon fiber straps, steel I beams or rebuilt wall sections depending on how far the wall has moved.
Settling and Sinking Foundation Repair
When one section of the house drops relative to the rest, we address what is under it. Depending on conditions that means underpinning, new footings or piering down to stable soil to stop the movement and, where possible, recover elevation.
Structural Masonry Repair
Rebuilding deteriorated block, brick and stone foundation sections, replacing failed units, repointing joints below grade and restoring load bearing capacity where the original masonry has broken down.
Underpinning and Footing Repair
Extending or rebuilding footings that were undersized, poorly poured or undermined by erosion and water. This is the fix when the wall is fine but what it is standing on is not.
Foundation Waterproofing and Drainage
Exterior membranes, drainage systems, French drains, regrading and downspout management to move water away from the structure. Most foundation problems in New Jersey are water problems first.
Parging and Foundation Resurfacing
Parge coating over block, stone and concrete walls to seal the surface, resist moisture and give the exposed portion a clean, finished appearance that holds up against weather and soil contact.
Crawl Space Foundation Repair
Repair and reinforcement of piers, footings, block walls and sill areas in crawl spaces, plus moisture control, since these areas hide damage for years before anyone looks.
Chimney and Porch Footing Repair
A leaning chimney, a separating porch or steps pulling away from the house usually means a failed footing rather than failed brick. We repair the footing so the same problem does not reappear after the masonry is rebuilt.
Full and Partial Foundation Rebuilds
When a section has deteriorated beyond repair, we rebuild it properly with correct footings, reinforcement, drainage and waterproofing, supported and sequenced so the structure stays safe throughout.
Foundation trouble rarely announces itself in the basement first. It usually shows up in the living space above. Watch for:
Horizontal cracking, any inward bowing and cracks wider than roughly a quarter inch deserve prompt attention. Those indicate active structural movement, and unlike cosmetic settling, they progress steadily once they begin.
We inspect the foundation inside and out, including grading, drainage, footings, crack patterns and the movement showing up in the living space above. Crack patterns tell us what kind of force is acting on the structure, which determines the correct repair.
You get a clear, itemized written estimate covering the recommended repair, materials, timeline and pricing. If your cracking is normal settlement that needs monitoring rather than reinforcement, we will tell you that instead of selling you a structural job.
Our crew executes the work with proper shoring, sequencing and materials for your foundation type, protecting the structure and your property throughout. Structural work is done in the right order for a reason, and we do not shortcut it.
We clean the site, walk you through everything that was repaired, explain what to watch for going forward, and make sure you understand the work before we call the job complete.
New Jersey foundations contend with expansive clay, a high water table in many towns, coastal salt exposure and freeze and thaw movement at the frost line. We use materials rated for that environment:
Materials and methods are selected based on your foundation type, soil conditions and the actual cause of movement, never by default.
Why Quality Foundation Repair Matters
✅ Protects the entire structure. Every wall, floor and roof load in the building transfers down to the foundation. Stabilizing it protects everything above it.
✅ Stops progressive damage. Foundation movement does not level off on its own. Addressing it early keeps a crack repair from becoming underpinning.
✅ Keeps water out. Sealed, properly drained foundations prevent the moisture that causes mold, rot and basement flooding.
✅ Protects property value. Foundation issues are the single biggest red flag in a home inspection, and documented professional repair preserves both value and buyer confidence.
✅ Restores doors, windows and floors. Once movement is stopped and corrected, the sticking doors and sloping floors upstairs stop getting worse.
✅ Prevents far costlier repairs. A crack sealed today is a fraction of the cost of the piering, wall rebuild and interior repair the same crack leads to.
