A waterproofing specialist should explain the moisture source, construction and proposed repair in a way the owner can evaluate. In Cyprus, as elsewhere, the most useful comparison is the investigation and written scope, not a universal claim that one coating or guarantee solves every leak.
Ask how the contractor distinguishes a roof or terrace defect from plumbing and condensation, how concealed areas are investigated and what remains uncertain. A confident answer is useful only when it is supported by observations and a repair design.
Start by describing the problem clearly
Give prospective contractors the same address, photographs and history. Include when the damp changes, the floor and room involved, what is above it and any recent building work. If each bidder receives different information, their quotes may describe different tasks.
Provide access details too: roof permissions, shared areas, narrow passages and occupancy. A quote issued without considering difficult access may omit a significant part of the work. The leak repair guide helps organize the initial evidence.
Questions to ask about diagnosis
- What observations support the suspected source?
- Which alternative sources have been considered?
- What cannot be assessed during the initial visit?
- Would a test or opening change the repair decision?
- What is the separate scope and price for that investigation?
A meter reading or thermal pattern can support an assessment, but it is not proof by itself. Beware of a repair specified from one reading or a photograph without the building context. Equally, avoid expecting a visual visit to establish every concealed layer with certainty.
Check that the method suits the assembly
A roof membrane, terrace under tiles and ground-contact wall have different conditions. Ask why the proposed system suits the substrate, use, exposure and existing layers. The waterproofing methods guide provides a non-product starting point for that conversation.
The proposal should describe preparation and the details at outlets, upstands, joints and penetrations. Compatibility with retained surfaces matters. Where movement or structural deterioration is suspected, the contractor should identify when additional professional input is needed rather than disguising it with a finish.
Compare written offers fairly
Check that each offer identifies the same area and includes access, removal, waste, protection and making good. Distinguish the source repair from internal plaster and painting. Ask what happens if removal reveals wet or unsound layers outside the assumed scope.
For a shared building, establish permissions and communication responsibilities. For an occupied home, ask about temporary restrictions, service interruption and how the working area is protected. A realistic programme follows the selected materials and conditions rather than a blanket promise of completion within a few days.
Read the guarantee for the actual job
Ask what the written guarantee covers, its period, maintenance requirements and exclusions. Material warranties and workmanship obligations are not necessarily the same. A broad website statement should not replace the terms of the particular offer.
Similarly, an inspection report can document facts for an insurer but does not guarantee reimbursement. Ask what documents you will receive and keep them with the accepted scope. Good records remain useful if the property changes hands or a manager takes over.
Maintain company records where applicable
For a Cyprus limited company owning the property, Sumly offers AI bookkeeping. Store inspection and contractor invoices against the repair budget; let your accountant determine their treatment.
Arrange an assessment with a clear next step
Our waterproofing service begins with the relevant building evidence. The standard Waterproofed inspection costs €100 plus 19% VAT (€119). Additional tests or opening-up are separately quoted so their purpose and reinstatement can be agreed.
Request an inspection with the location, photographs and timing. After assessment, you should be able to distinguish observed findings, a supported repair scope and any further investigation still required. That makes the decision concrete instead of relying on a promise to fix every possible cause.
Frequently asked questions
What makes a useful waterproofing proposal?
It connects the evidence to a defined repair, including preparation, junctions, access and making good. It states limitations and any further investigation instead of presenting an unsupported guess as confirmed.
Is a long advertised guarantee enough to choose a contractor?
No. Read the actual job terms, covered work, maintenance conditions and exclusions. The diagnosis and installation scope are still essential to assessing the offer.
Should a specialist quote the repair from photos alone?
Photos can help with initial discussion, but they may not establish construction, hidden damage or access. A dependable final scope can require site assessment and further investigation.
