Why Fiber Cement Needs Its Own Notes
Hardie plank and other fiber cement siding are not the same cleaning problem as driveway concrete. Paint condition, lap seams, trim, caulk, vents, outlets, landscaping, and runoff can all affect how a house washing request should be reviewed.
Houston humidity and shaded elevations can leave mildew, algae, pollen film, and soil splash on siding. Use house washing for the broader exterior scope and soft washing when comparing lower-pressure method planning.
What to Document
- Mildew, algae, pollen film, soil splash, or roof runoff marks
- Paint condition, lap seams, trim, caulk lines, vents, and outlets
- Shaded side elevations, tree cover, and irrigation overspray
- Landscaping, pools, drains, low spots, and drainage direction
- Whether brick, stucco, concrete, patios, or gutters are included
Method Boundaries for Siding
Fiber cement siding should be reviewed as a house-washing surface, not as concrete. The request should note paint age, visible flaking, caulk gaps, lap seams, trim details, and areas where water could be pushed behind siding or into wall penetrations.
Lower-pressure planning is usually the safer starting point for siding conversations. If the same property also needs driveways, patios, brick, or gutters cleaned, separate those surfaces in the request so each material can be reviewed on its own terms. The soft wash vs pressure wash guide explains why siding and concrete should not be scoped with the same method assumptions.
Why Drainage and Gutters Matter
Mildew patterns on Hardie plank often connect to shade, roof runoff, blocked gutters, irrigation overspray, or soil splash at the base of the wall. Include photos of downspouts, roof edges, splash areas, mulch beds, and low spots so the siding request does not miss the moisture source.
When to Route to Other Services
If the request includes orange marks below a fixture or AC line, add rust stain removal to the review. If the lower wall is stained by splashback from concrete, include concrete cleaning or patio cleaning notes. If the same elevation has brick, stucco, and fiber cement together, document each material separately so the plan does not rely on one method for the whole wall.
For Houston homes under mature trees, it also helps to include seasonal context: recent pollen drop, leaf debris, gutter overflow, irrigation timing, or shaded side yards. These details can explain why mildew is concentrated on one elevation instead of evenly across the house.
