An exterior leak can involve more than one trade. A balcony meets a door; a roof meets a stucco wall; a window interrupts the cladding. When each piece is priced separately, the connection between them can be overlooked.
Map the affected area
Photograph the full elevation and identify the interior symptom, if there is one. List nearby openings, decks, trim, and roof edges. Include the repair history and any inspection findings so the conversation starts with more than the visible stain.
Ask how the systems meet
A proposal should explain the boundary between roofing, wall repair, door or window work, and deck waterproofing. Ask who is responsible for the tie-ins and what happens if a concealed connection cannot be reached within the initial scope.
A coating is a specific component
Ask where a proposed coating is approved for use and what preparation it requires. A wall coating, traffic-bearing deck system, and roof product are not interchangeable simply because each is described as waterproofing. Request the actual product information and the intended assembly.
Agree on the sequence and records
- Identify any investigation needed before final pricing.
- Confirm which trade works first and how the site stays protected.
- Document concealed transitions before they are covered.
- Define any testing and its limitations.
- Keep maintenance instructions for the installed systems.
Exterior rain-management work should not be represented as protection against every flood condition. Explain the water exposure you are concerned about so the correct scope can be discussed.
