Ground, Housing and Foundation Repair in Jericho
Capes, ranches and high-ranches are common, and many have finished basements or lower levels that were converted after the house was built. Dense neighborhoods with mature street trees mean clogged gutters and root intrusion into older sewer laterals are frequent sources of water trouble.
Where the water table rises in a wet spring, basements that stay dry for years can suddenly seep at the floor-wall joint. Much of the housing went up in the postwar boom of the late 1940s through the 1960s, so many homes are now 60 to 75 years old, with original drain lines, water heaters near the end of their life, and basements that were never waterproofed.
What that means for foundation repair in practice: Concrete stoops, walks and patios that settle toward the house can direct water into the basement. Hairline shrinkage cracks are normal; cracks that widen, offset or let water in should be looked at.
This page covers Jericho, ZIP code 11753. In early spring, when the ground is saturated, check the floor-wall joint in the basement for new damp spots.
Foundation Repair Services Available in Jericho
Start with the first few sections: they cover the problems most often reported around Jericho. Each includes what the work involves and the signs to watch for.
Foundation Crack Injection in Jericho
Not all foundation cracks are equal. Thin vertical cracks in poured concrete are usually shrinkage and are mainly a leak risk. Stair-step cracks in block or brick, horizontal cracks, cracks that are wider at one end, and cracks where one side has moved relative to the other indicate movement and need an evaluation. Epoxy injection bonds a structural crack back together; polyurethane injection seals a crack against water while allowing slight movement.
For Jericho homes, this is often one of the first things a pro will look at.
- Water or rust stains at cracks
- Cracks that have grown since you first noticed them
- Horizontal cracks in a basement wall
Foundation Assessment for Jericho Homes
A thorough foundation inspection looks at the whole house, not just the crack that worried you. Expect the inspector to walk the exterior for grading and drainage problems, check the basement or crawl space for wall movement and moisture, measure floors for slope, and note doors, windows and drywall cracks upstairs. Together those observations show whether the house is settling, being pushed by soil, or simply showing normal cosmetic cracking.
In Jericho, this ranks among the most frequent reasons homeowners call.
- Gaps between walls and the ceiling or floor
- Sloping or bouncy floors
- Doors and windows that stick or won't latch
Foundation Settlement Repair for Jericho Homes
Foundation settlement happens when part of the house sinks because the soil beneath it gives way. Look for patterns: cracks that open wider toward the top, floors that slope toward one corner, doors that rub at the top, and gaps around windows or between an addition and the house. Repairs usually support the footing with piers that reach firmer soil, and they work best when the water problem that softened the soil is also fixed.
For Jericho homes, this is often one of the first things a pro will look at.
- A gap where an addition meets the house
- Doors that rub at the top on one side
- A chimney pulling away from the wall
Concrete Slab Leveling in Jericho
A slab that sinks toward the house is a waterproofing problem as much as a trip hazard, because it channels rain straight to the foundation. Before lifting, the cause of the settlement, often water washing out soil beneath the slab, should be addressed so the slab doesn't sink again. Cracked or crumbling slabs may need replacement rather than lifting.
- Driveway or walk sloping toward the house
- Trip hazards at slab joints
- Water pooling on a patio or garage floor
Leaning Foundation Wall Repair in Jericho
When saturated or frozen soil pushes on a basement wall, block walls can crack horizontally and bow inward, and poured walls can tilt. Wall anchors run steel rods through the wall to plates buried in stable soil in the yard and can be tightened over time; steel I-beam braces run from the floor to the floor joists; carbon fiber straps bonded to the wall add tensile strength for walls with limited movement. The right choice depends on how far the wall has moved and how much room there is outside.
- Mortar joints pushing in
- Horizontal crack along the middle of a block wall
- Water entering along the horizontal crack
Front Step and Stoop Repair in Jericho
Porches on piers can sag as posts settle or rot. Supporting or replacing piers, posts and beams can restore level and keep the porch roof from pulling on the house. A stoop or porch that pulls away from the house also puts strain on the ledger or connection, so it's worth checking before it gets worse.
- Steps tilting toward or away from the door
- A porch floor that slopes or bounces
- Cracks running through the stoop
Other Foundation Repair Services
Pros serving Jericho also handle push piers and helical piers, crawl space support and sagging floors. These come up less often locally but follow the same approach: find the source, then fix it.
Before You Call: What to Check
- Photograph cracks with a ruler or coin for scale, and note the date.
- Mark the ends of cracks with a pencil so you can see whether they grow.
- Find any past inspection reports or repair records.
- Note doors and windows that stick, and where floors slope.
How Local Pros Typically Handle the Job
- Evaluation. Expect a floor-level survey, crack measurements and an inspection of walls and drainage.
- Cause. A good evaluation identifies the cause, not just the symptom, before proposing a repair.
- Repair plan. You get a written plan with the method, number of piers or anchors, permits and price.
- Repair and drainage. Repairs are completed and drainage issues addressed so the problem doesn't return.

Horizontal cracks, stair-step cracks in block or brick, cracks wider than about 1/4 inch, and cracks that keep growing or are offset should be evaluated. Hairline shrinkage cracks are normal; cracks that widen, offset or let water in should be looked at.
Why do doors stick in my Jericho home?
Doors that stick or won't latch can be a sign of foundation movement, especially if cracks appear above door frames. Humidity can also swell doors, so note whether the problem comes and goes with the seasons. Hairline shrinkage cracks are normal; cracks that widen, offset or let water in should be looked at.
Should I get a structural engineer in Jericho?
For major cracks, bowing walls, significant settlement, or when buying or selling a home, an independent engineer's report helps define the problem and makes contractor quotes easier to compare.
