How to budget maintenance without surprises

Maintenance budgets split into three buckets. Getting the mix right prevents surprise capital expenditure.

1. Routine (OPEX)

Cleaning, inspection, minor repairs. Budget 0.3–0.5% of replacement value annually.

2. Cyclic (planned CAPEX)

Sealant renewal, anchor replacement, drain upgrades. Budget 0.5–1% every 5 years.

3. Reactive (emergency reserve)

Storm damage, accidents, urgent repairs. Reserve 0.5% of replacement value.

With these three buckets, every maintenance decision is pre-justified and the budget conversation becomes a capital allocation conversation rather than an emergency.
