Siding and trim are the parts of the building that keep water out of everything else.

Usually. On cedar clapboard and shingle it is a question of matching exposure, grade and profile, then letting new stock weather in. On vinyl from a discontinued run we source the closest available profile and color, and where a match is not realistic we say so up front and suggest doing a full elevation instead of a visible patch.

Sectional repair is normal work for us. If the substrate and the rest of the wall are sound, replacing the failed area and correcting the flashing is the right call. Full replacement makes sense when failure is widespread on an elevation or when the sheathing behind it is wet across a large area.

Sometimes, and we would rather find it during the scope than mid-project. Where we suspect it, we open a small area first. If sheathing or framing is involved, you get that as a separate, clearly priced line rather than a surprise change order after the staging is already up.

It is exterior work, so units stay occupied. Staging or ladders go up on the elevation being worked, parking near that side is affected, and there is noise during working hours. We give notice of which building and which elevation is next so managers can send residents something ahead of time.
