About This Service
Separate Joint Work From Unit Replacement
Repairing a mortar joint and replacing a damaged masonry unit are different tasks. Twin explains which material is affected and what preparation is proposed. If both are included, the estimate should identify their relationship instead of naming the whole project as a surface patch.
Retain Sound Material Where Appropriate
The repair recommendation should distinguish what needs removal from what can remain. Retaining a component depends on its condition and role in the assembly, not simply its age. We discuss that decision so a localized repair and a larger replacement can be compared meaningfully.
Plan Removal of Damaged Material
The scope should describe which material is being removed and which surrounding parts remain. That distinction affects preparation and repair boundaries. We discuss any uncertainty before starting and explain new findings that change the proposed work before asking for additional authorization.
Separate Cleaning From Repair
Removing deposits and repairing damaged material have different purposes. If both are recommended, we explain the scope and sequence of each. A completed cleaning does not mean broken components were repaired, and an exterior repair does not automatically clean the venting passage.
