Most concrete calls are about a surface that has stopped behaving: a driveway that pools water, a stoop with a crumbling edge, a patio that has heaved, a brick wall with a white bloom on it. Masonry adds another layer, because brick and block move with moisture and settle with the ground. A local pro can tell you whether the fix is a patch, a rebuild, or a drainage problem wearing a concrete disguise.
Call now
- A retaining wall is leaning, bulging, or has soil pushing through it.
- Steps or a stoop have separated from the house, or a slab has dropped sharply at one edge.
- Water is running against the foundation and into a basement or crawlspace.
Can usually wait
- Hairline cracks with no offset on a driveway or patio.
- A stained or chalky brick wall with sound mortar.
- A single loose capstone or a chipped step edge.
Have this ready
- Photos with a coin, ruler, or shoe for scale.
- The age of the concrete or brick, if you know it.
- Where water goes when it rains, and whether the area has ever been repaired.
What the desk hears most
- 01
A driveway that has settled or cracked
Tree roots, a thin base, heavy vehicles, and freeze-thaw all leave a signature. A crack that runs straight and stays tight is different from a slab that has dropped at the garage apron. Patching hides the line; it does not fix the base.
- 02
Crumbling steps and stoops
Spalled edges, loose bricks, and a hollow sound underfoot usually mean water got in and froze. A step that has separated from the house is a movement question. Rebuilding the treads is often cheaper than repeated surface patches.
- 03
A patio that heaves or ponds
Water that stands after a rain is telling you the base or the slope is wrong. Frost can lift a slab in one winter. Pavers can sometimes be reset; a poured slab may need sections replaced or a new pitch.
- 04
Brick spalling and mortar joints
Flaking brick faces and recessed mortar let water deeper into the wall. Repointing with a mortar harder than the brick can make it worse. The right repair matches the old mortar and finds the moisture path.
- 05
A retaining wall under pressure
A wall that bulges or leans is holding soil and water it was not designed for. Weep holes, backfill drainage, and footing depth decide whether it stands. A tall wall may need an engineer, not a cosmetic patch.
Call now or wait?
The honest answer depends on whether the problem is contained and whether the house is safe. Use these two lists as a starting point, then call and describe the specifics.
Call now
- A leaning retaining wallKeep people and vehicles away from the wall and the soil above it. A wall can fail suddenly after rain, and the pressure does not stop because the surface looks fine.
- A stoop or step pulling awayBlock the step and use another entrance. A separated stoop is a fall risk and often a sign that water has been undermining the base.
- Water entering at a foundation crackMove water away from the wall with a downspout extension or a temporary berm, then call. A wet basement gets worse with every storm; the crack and the drainage both need attention.
- A crack that has widened since you last lookedMark the ends with pencil or tape and keep the area clear. Movement over weeks, not years, deserves a prompt look from a concrete or foundation professional.
Can usually wait
- Hairline cracks in a drivewayMost are cosmetic and stable. Clean them, watch them over a season, and seal only after the cause of any movement is understood.
- A stained patioRust, leaf tannin, and efflorescence are surface issues until the surface starts to flake. Clean gently and avoid blasting the joint sand out of pavers.
- A chipped step edgeA small chip is a cosmetic repair, but it can become a trip edge. Avoid the corner and plan a patch or a rebuild before winter.
- Loose bricks in a garden wallA low garden wall is not holding a house up. Keep weight off it and have the mortar and cap checked before the next freeze.
Before you dial: the 60-second prep
You do not need a diagnosis. You need enough detail for the desk to route the call and for the pro to arrive with the right questions.
- Photograph the crack with a ruler across it and note the date.
- Mark the ends of a crack with pencil or tape and check it in a month.
- Note where downspouts, gutters, and grades send water.
- Clear access for a truck, wheelbarrow, or mixer.
- Find out whether the slab has rebar or mesh, if any records exist.
- Keep cars and feet off the area until it is assessed.
What happens when you call
What moved and where the water goes
Describe the crack, the settled slab, or the leaning wall, and trace the path of rainwater for the desk. A photo with a ruler or a shoe in frame gives the damage a scale.
A specialist for the material
Concrete flatwork, brick repointing, and retaining walls are related but not identical trades. The call is routed to an independent local professional who works the material and the failure you have.
Repair, rebuild, or drainage
The site visit should separate a surface fix from a base or water problem. Ask what the assessment covers, whether an engineer is needed, and what the visit or estimate involves.
What changes the job here
Housing age, weather, water, soil, and foundation type all change how a concrete & masonry problem behaves. These are the local factors worth mentioning on the call.
Freeze-thaw and deicing salt
In cold regions, water in a pore expands and flakes the surface. Air-entrained concrete, a good slope, and sand rather than salt reduce the damage. Sealing a new slab too early can trap moisture instead of protecting it.
Expansive clay soil
Clay that swells and shrinks moves slabs and walls with the seasons. On that ground, a thicker base, proper grading, and deep footings matter more than a decorative finish. Ask how the site drains before a new pour.
Hot, dry summers
Concrete cures too fast in heat and wind, which brings shrinkage cracks and a weak surface. A contractor who waters, shades, or schedules an early pour is protecting the slab, not delaying the job.
Coastal salt and driven rain
Salt air attacks mortar, ties, and rebar, and wind-driven rain finds every open joint. Corrosion-resistant hardware and a wall detail that sheds water are part of the repair, especially within a few miles of the coast.
Questions worth asking the pro
Ask before you authorize work. A good professional will answer plainly, including the parts that are still uncertain.
- Is this cosmetic, or is the base or structure moving?
- Do you repair, resurface, or replace?
- How will you handle drainage away from the wall?
- Will you tie into the existing slab or pour it separately?
- What mix and finish are you using, and how long before we use it?
- Does a retaining wall this height need a permit or an engineer?
