Begin with the source of deterioration
Before specifying paint or replacement siding, record damaged areas, previous repairs, and where water has entered. Ask how the proposed work addresses the adjoining roof edge, flashing, sealants, openings, and drainage.
Define a complete exterior package
- Identify surfaces to repair, retain, coat, or replace.
- Confirm material profiles, colors, sample approval, and preparation requirements.
- Separate windows, doors, fencing, and masonry work so each has a clear scope.
- Plan access to entrances, parking, landscaping, and occupied units.
Evaluate the assembly and the upkeep
EPA moisture guidance treats walls, roofs, and drainage as connected parts of the building. Use that perspective when comparing proposals, then ask for the product-specific care requirements and details for future repairs.
