Waterproofing assessment and quotation in Madrid

Information for comparing proposals: assessment, scope, materials where relevant, access, documentation and exclusions.

What to clarify in the proposal

1. Assessment and investigation needed before proposing work.
2. Preparation: removals, cleaning, corrections and substrate treatment.
3. System and details: materials, compatibility, outlets, interfaces and joints.
4. Access and use: affected areas, protection, safety and operations.
5. Handover: waste, reinstatement, documentation, exclusions and additional work.
6. Terms: price, payments, agreed warranty and maintenance.

What should I receive before accepting?

A description of the work, assessment and access conditions, inclusions, exclusions and how changes are approved. The quotation should distinguish investigation, repair and reinstatement.

Define removals, corrections, protection, materials, interfaces, outlets, waste and finish. Ask how the work will be checked and what maintenance is recommended. A local repair may have limits; full replacement also needs justification. Scope should follow assessment and be understood before contracting.

Preparing your enquiry

Provide the location, visible water area, timing and earlier interventions. Plans or existing system information may help.
