Siding and exterior repair

The wall is part of the floor system's protection

Siding on a manufactured home is doing what siding does anywhere: shedding water away from the structure. The consequence of failure, though, is specific to this construction.

Water that gets behind the siding runs down inside the wall cavity and arrives at the bottom plate and the floor system. There is often no interior sign at all — no stain, no smell, no visible damage — until the floor along that exterior wall goes soft, sometimes years later.

This is why we treat an exterior repair as urgent earlier than it looks. A cracked panel and a failed sealant joint at a window head are cheap. The subfloor replacement they cause is not.

Substrates, and what each needs

Vinyl lap. The most common on homes from the last twenty-five years. Profiles and colours from roughly the last fifteen are usually still available, which makes single-panel repair realistic. Older colours have often faded far enough that even a correct match reads as new.

Metal panel. Common on older homes. Durable but easily dented, and profiles are frequently discontinued. Damage is often better addressed by replacing an elevation than by hunting a match.

Hardboard composite. Used widely into the 1990s and the one to know about. It absorbs water at cut edges and at fastener penetrations, then swells and delaminates. Once that has started it cannot be refinished — paint over swollen hardboard fails within a season and takes the labour with it. It gets replaced.

Matching, honestly

We will match where matching produces a result you cannot pick out from the street, and we will say so plainly where it will not.

The failure mode to avoid is a near-match: a panel in almost the right profile, or the right profile in a colour that has drifted, patched into the middle of an elevation. It reads as a repair from a hundred feet away, and on a community perimeter that is worse than the damage was — because damage reads as an accident and a bad patch reads as the standard.

Where a match is not available, replacing the full elevation gives a clean result and is often barely more expensive than a careful patch once the labour of hunting material is counted.
