What goes wrong for paver patio.

Symptoms first, quotes second

Most expensive paver patio mistakes start with a symptom described to a salesperson. The table maps the common symptoms to their usual cause — the diagnosis a contractor should confirm before quoting.

SymptomUsual cause
Weeds in jointsMissing polymeric sand
SettlingThin or wet base
EfflorescenceSalt migration, cosmetic
Rutting under carsBase not designed for loads
Drainage poolingFall and slope wrong

What to document

  • Photographs with something for scale, taken at the same angle over time.
  • Dates: when it started, whether it changes with weather.
  • Water: where it goes, where it pools, what it damages.
  • Previous work: who did it, when, and with what material.

What not to do first

Do not accept a repair scope before the cause is named. Patching a symptom is how the same problem returns next season with a bigger invoice. The methods hub explains what each fix addresses; the cost hub shows what it should cost.

When is it an emergency?

When water is entering the structure, when something is structurally unstable, or when a safety system has failed. Everything else can wait for a second opinion.

Should I get an independent inspection?

For anything structural or over about $5,000, yes. A few hundred dollars for an independent report is cheaper than a wrong scope.
