A widening seam between an exterior slab and the house foundation is one of the clearest signs the slab — not the house — is on the move.
When an exterior slab drops, anything anchored to it — a gate post, a stoop, a threshold — can bind or misalign even if the house structure itself is fine.
A slab that used to slope away from the foundation and now slopes toward it is actively redirecting water where you don't want it.
A hairline crack that hasn't changed in years is very different from one that's visibly opening — active movement is the signal to act on.
Addressing a settling slab early, while it's a few injection holes and an afternoon of work, is far cheaper than waiting until it affects an adjacent structure.
A sinking slab next to a foundation, a pool, or a utility line isn't just a standalone problem — the soil issue causing it can affect neighboring structures too.
Once a slab tilts toward the house, every rain and irrigation cycle adds more moisture to the same soil that's already failing — a feedback loop worth breaking early.
Work this close to a foundation deserves a contractor who understands the difference between a slab issue and a structural one, and who won't oversell or undersell the situation. Every contractor matched through Phoenix Concrete Lifting is vetted and insured before they're ever connected with a homeowner.

Not necessarily — exterior slabs (patios, stoops, walkways) are usually separate structural elements from the foundation itself, and can settle independently. That said, if you're also seeing cracks inside the house or on foundation walls, it's worth having both assessed together.
It depends on the rate of movement and what's nearby — a slowly settling walkway is lower urgency than one actively redirecting water toward a foundation. A contractor can assess the specific situation and tell you honestly how time-sensitive it is.
Lifting the slab back to its proper slope restores drainage that was working before it settled, which is often a meaningful part of the fix — but if the underlying grading or gutter system was already a problem, that may need separate attention.
Common causes include soil erosion from downspouts or irrigation concentrated near the house, the original backfill around the foundation being less compacted than native soil, and expansive clay movement — a contractor can help identify which is driving your situation.
