This guide improves offer literacy; HouseSymptoms does not recommend contractors, compare prices or broker work. Distinguish performance requirement, named product, equivalent substitution and compatibility with existing layers.
Translate the wording into deliverables
Identify the location, quantity, layer, method, protection, access, waste, reinstatement and document promised by each line. Separate included work from assumptions, provisional sums and exclusions.
Questions that expose ambiguity
- What evidence supports the proposed scope?
- What happens if concealed conditions differ?
- Who authorizes and prices added work?
- What is the completion and verification criterion?
Compare offers on completeness, sequencing, responsibility and uncertainty—not price alone.
Before accepting
Confirm regulated-work responsibility, insurance coordination, payment milestones, warranty language, documentation and the boundary between investigation and repair.
Compare completeness before cost
Place competing offers beside the same evidence question and scope sequence. Mark missing access, drying, reinstatement, protection, documentation and verification items. A lower total may simply omit work or transfer uncertainty to later change orders.
Neutral boundary
HouseSymptoms provides educational reading support only. It does not validate a company, price, contract or legal position. Stop ordinary self-help when there is active electrical or combustion danger, sewage, suspected hazardous material, unstable structure, unsafe access, rapidly spreading water, regulated work, acute occupant symptoms or an insurance-preservation reason not to disturb the scene.
