Investigation and replacement boundaries
A cracked fiberglass replacement scope should include inspection of the supporting floor and connections when the unit is removed. Specify the new unit's support requirements and any conditional substrate work. Replacing the shell without identifying relevant movement can leave an important part of the scope unresolved.
Set a hold point for concealed conditions
Document what is known before removal and what will be checked after access is available. Require findings and a proposed scope change before authorizing additional concealed work. The final assembly should be specified only with those findings accounted for. This is a substantial remodeling pathway; repair-only work, service calls and isolated maintenance are not established as accepted services.
What evidence should support additional work?
Documented findings after assessment or opening, with a description of the proposed correction. A crack photograph alone does not establish the condition of the concealed floor or plumbing.
The owner should confirm the proposed service scope and provider availability independently. This guidance does not identify an approved contractor, establish coverage for a specific property or guarantee acceptance of the project.
The written scope is the reference.Use the provider’s proposal to record the accepted work, products, responsibilities and exclusions. Website examples do not establish an installation specification for your home.
