Texas summers and storm bursts are tough on exterior surfaces. Concrete slabs expand and shrink with temperature swings and soil movement; wood decks take UV, heat, and repeated wetting. The result: cracks, loose fasteners, heaved sections, and slippery or unstable walking surfaces. 

Why cracks and failures happen here

• Expansive clay soils: Much of Texas sits on shrink–swell clays. Dry spells shrink soil; heavy rain swells it. That movement stresses driveways, sidewalks, and slab-on-grade patios, causing cracking and uneven sections. 
• Thermal movement in concrete: Slabs expand and contract with heat. Without well-placed joints and maintained sealants, stresses show up as random cracks and spalls. 
• Wood deck exposure: Heat and UV degrade coatings; wet/dry cycles swell and shrink boards and framing. Durable species, preservative treatment, and good moisture management extend deck life. 
• Safety risk is real: National deck groups push annual inspections because fasteners, ledgers, rail posts, and stairs can loosen or decay unnoticed. 

Early signs to act on

• Driveways/patios: New cracks that widen after rain/drought cycles, lifted trip edges, settled sections holding water, crumbling joint sealant. 
• Decks: Soft or split boards, wobbly rails, corroded connectors, rusted or missing flashing at the ledger where the deck meets the house; loose or bouncy stairs. 

What to do this season 

Concrete & hardscape

• Clean and seal joints. Remove debris; re-seal control and expansion joints to accommodate movement and keep water out. Plan joint spacing and repairs per ACI guidance. 
• Fill narrow cracks; address causes for larger ones. Use a crack filler for hairlines; for wide or recurring cracks, check drainage and soil movement before resurfacing. 
• Fix drainage. Redirect downspouts and irrigation away from slabs; standing water accelerates damage. 

Decks & stairs

• Inspect structure, not just boards. Check ledger flashing, joist hangers, post bases, rail posts, and stair stringers; tighten or replace corroded hardware. Follow deck-safety checklists (NADRA). 
• Replace failed boards and re-coat. Use exterior-rated fasteners; clean, dry, and re-seal/paint on a dry, mild day. FPL research emphasizes durable species/treatments and moisture control. 
• Improve traction. Add anti-slip finishes on high-traffic treads and entries.

Safety note: If any section feels unstable—or the ledger, rails, or stairs move—don’t use the deck until a pro evaluates it. 

When to repair vs. replace

• Driveways/patios:
  • Repair/resurface if cracks are cosmetic and slab movement is minor.
  • Replace sections if slabs are badly heaved/settled or keep re-cracking after joint and drainage fixes (soil movement likely). 
• Decks:
  • Repair if issues are limited to a few boards or fasteners.
  • Replace (partial or full) if the ledger, framing, or posts show decay/corrosion—especially near the house connection.

Quick maintenance calendar 

• Spring: Clean slabs and joints; re-seal concrete joints as needed. Deck safety check (ledger, rails, stairs, fasteners). 
• After big storms: Walk the driveway and deck for new cracks, settlement, loose rails, or ponding. Document with photos. 
• Fall: Re-coat decks before winter moisture. Confirm drainage keeps water off slabs and away from foundations. 

Bottom line

In Texas, heat and storm cycles speed up damage outside. Concrete slabs move and crack; wood decks loosen, rot, and get slick. Stay ahead with simple habits: seal concrete joints, fix drainage, and do an annual deck safety check (ledger, rails, stairs, fasteners). 

Don’t ignore trip edges or wobbly rails—those are safety issues, not just maintenance. If you’re unsure whether to patch, resurface, or replace, get a quick read from a pro at letsaskjack.com.
