Foundation Repair
Sorting a visible foundation problem into the right category before anything gets fixed.
Foundation problems, worked out before anything gets cut or dug
A crack that keeps coming back. A door that used to close and now catches on the frame. A floor with a slope you can feel in your socks. Tell us what your house is doing and we will work out which of ten foundation, crawl space or retaining wall categories it actually falls into — before anyone recommends a fix.
Describe what you are seeing
Foundation problems, and what each sign usually points toward
- A crack in a wall, slab or foundation that is new or growingMost cracks are cosmetic. The ones worth a closer look are wider than a pencil lead, run diagonally from a corner, or keep reopening after being patched — see which foundation cracks are serious for how to tell the difference yourself.
- A door or window that used to close easily and now sticksFraming moves when whatever it sits on moves. A door that binds at the top corner and a window that will not latch square are both classic signs of uneven settling, not just an old house settling into its frame.
- A floor that visibly slopes, or a spot where a ball would rollOne area of the foundation has moved relative to the rest. Whether that calls for settlement repair or house leveling depends on how much of the structure is affected and how it is built — the two are genuinely different jobs.
- A crawl space that feels damp, smells musty, or has visible moistureMoisture under the house is a separate problem from structural movement, and treating one as the other wastes money. Crawl space encapsulation addresses the moisture; a sagging or damaged crawl space frame is a structural repair.
- Water entering a basement or a below-grade roomWhere the water is coming from — the walls, the floor, a window well — changes the answer. See basement waterproofing and foundation waterproofing for how those two related problems actually differ.
- A driveway, patio or walkway slab that has sunk or tiltedFlatwork settling is a different problem from the house settling, and a much smaller job. Concrete lifting addresses a sunken slab without touching the structure above it.
- A retaining wall that is leaning, bulging, or has a new crackA retaining wall holds back soil under real, constant pressure, and it is a separate structure from the house foundation entirely — see retaining wall repair for the specific signs that mean it needs attention soon rather than eventually.
Related services
Settlement Repair
Stopping and correcting ongoing, uneven movement of the foundation itself.
Foundation Crack Repair
Telling a cosmetic crack from a structural one, and closing or monitoring it accordingly.
Crawl Space Repair
Sagging joists, failed piers, or damaged framing under the house — the structural half of the crawl space, not the moisture half.
Crawl Space Encapsulation
Moisture, humidity, and musty smells under the house — the vapor and environmental half of the crawl space, not the structural half.
Foundation Waterproofing
Water moving into or through the foundation itself from the outside — grading, exterior sealants, and drainage around the structure.
Basement Waterproofing
Keeping water out of a basement that is actually lived in or used for storage, not just the foundation around it.
Concrete Lifting
Raising a sunken driveway, patio, or walkway slab back to level — flatwork, not the house itself.
House Leveling
Restoring the structure itself to level, distinct from stopping the ground movement that caused it to move.
Retaining Wall Repair
A leaning, bulging, or cracked retaining wall is its own structure with its own repair questions, separate from the house foundation.
How a diagnosis actually runs
Why a foundation symptom shows up somewhere other than the cause
A house is one connected structure sitting on ground that does not move evenly. Soil under one corner can expand, contract, or compact at a different rate than soil under the rest of the footprint — and when it does, the effect travels through the framing before it becomes visible anywhere. A crack in a bedroom wall can trace back to a footing on the opposite side of the house. A door that sticks upstairs can be evidence of something that started at the slab. That is the reason ten different pages exist here instead of one generic "foundation problems" page. Foundation repair, settlement repair, crack repair, crawl space work, waterproofing, concrete lifting, house leveling, and retaining wall repair are not different names for the same service — they are different categories of problem, with different causes, different methods, and in several cases different professionals qualified to assess them. Naming the right one first is what keeps the next step useful instead of a guess.
What actually varies across San Diego County
Housing age and soil condition both vary meaningfully across the county, and neither correlates neatly with distance from the coast. Older urban-core neighborhoods carry a wider range of foundation types and repair histories than newer subdivisions built to a single code era. Hillside and canyon-adjacent lots, common across much of the county's terrain, introduce grading and retaining-structure considerations that a flat inland lot never has to deal with. Coastal areas see different moisture and drainage patterns than inland valleys that see more temperature swing. None of that supports a specific diagnosis for a specific house from a description alone — soil, drainage, and foundation type all have to be seen, and in many cases only a licensed structural engineer or geotechnical professional can say with certainty what is happening underneath a given property. What it does support is a starting question: which of the ten categories above does what you are describing actually sound like, and where in the county is the property.

Which Foundation Cracks Are Serious?
How width, direction, and pattern separate a cosmetic crack from one worth a professional look.
Common Causes of Foundation Settlement
The general, well-documented reasons a foundation settles — and how to confirm which one applies to a specific house.
House Leveling vs. Foundation Repair
Leveling fixes the symptom. Foundation repair addresses the cause. Here is how the two relate.
What this site is, plainly
Informational first, matching second
Home Foundation Experts explains the ten categories of foundation-related problems in plain language and, where it can help, connects a visitor with an independent local provider. It does not perform foundation work itself.
No invented credentials
No claimed years in business, no manufactured review counts, no promised response time, no assumed licensing or insurance on anyone's behalf. What can be verified is described; what cannot is left unsaid rather than implied.
The right category before the right contractor
A crack and a settlement problem are not interchangeable, and neither is the professional qualified to address each one. Naming the actual category first is the whole point of the ten pages this site is built around.
Independent providers, independently verified by you
Any provider you are connected with is independent, not our employee — see the contractor matching disclosure for exactly what that means and what to confirm before any work begins.
Questions people ask
How do I know if a crack is serious or just cosmetic?
Width, direction, and pattern all matter more than length. A hairline vertical crack is usually cosmetic; a crack wider than about a quarter inch, running diagonally, or stair-stepping through masonry joints is worth a closer look. See which foundation cracks are serious for the specific checks.
Is a sloping floor always a foundation problem?
Usually, but not always — an older home can have a slight, long-settled slope that is not actively worsening, versus a new or worsening slope that points at active movement. The difference matters and is not something to guess at from how the floor feels underfoot alone.
Do I need a structural engineer or a foundation repair contractor?
Often both, in that order. A licensed structural engineer can provide an independent assessment of what is happening and why; a foundation repair contractor then executes a specific method. For anything beyond a clearly cosmetic issue, an independent engineering opinion before committing to a repair method is worth the cost.
Can I get a price without anyone seeing the property?
No, and treat any number offered sight-unseen with real skepticism. Foundation, crawl space, and retaining wall repair costs depend on access, soil conditions, method, and the extent of the problem — all things that require an actual inspection.
What if I'm not sure which of the ten categories applies?
That is the normal starting point, not a problem. Describe what you are seeing — where, how long, whether it is getting worse — and that description is enough to point toward the right category and the right next step.
Does Home Foundation Experts do the repair work itself?
No. This is an informational and lead-matching site — it explains the problem categories and may connect you with an independent local provider, who is responsible for their own licensing, insurance, and work. See the contractor matching disclosure for the full explanation.
