Why This Matters
Manufacturer warranties on most siding materials require the homeowner to perform basic maintenance — annual washing, caulking inspection, and prompt repair. Skipping it can void a 30-year warranty in 3 to 5 years. This generator creates a custom yearly checklist based on your siding material (vinyl, fiber cement, engineered wood, wood, metal) and climate (humid south, freezing north, dry west, coastal salt). It tells you exactly when to inspect, when to wash, when to re-caulk, and when to call a pro.

Frequently Asked Questions
Once a year with a soft brush and mild soap. Twice a year in humid or coastal areas where mildew grows faster. Pressure washing is fine if done on a low-pressure setting; high pressure can drive water behind the panels.
Pre-painted fiber cement (like ColorPlus from James Hardie) typically holds color for 15 to 25 years. Site-painted fiber cement needs a quality acrylic exterior repaint every 7 to 12 years to maintain warranty coverage.
Inspect every spring. Most exterior caulk lasts 3 to 7 years before it cracks or pulls away. Recaulk immediately when you see gaps — water behind the siding causes hidden damage that is much more expensive to fix.
Yes — keep at least 12 inches of clearance. Plants touching siding hold moisture, cause mildew, scratch the surface during wind, and let pests reach your home. This is the single most-skipped maintenance item.
