FROM OUR PROJECT COLLECTIONCheck the condition behind the visible joint
Earlier sealants or patches can affect the material a new treatment must connect to. Ask what the existing surface is and whether the proposed product is compatible with it. The appropriate scope may involve replacing a flashing component or repairing a membrane detail rather than adding another layer over everything present. If access reveals deteriorated decking or other damaged layers, request a separate explanation of the additional work. A waterproofing treatment should not obscure those findings or make it unclear which components the contractor intends to remove, retain and replace as part of the repair.
