How to choose a damp proofing company in Cyprus

What separates a damp proofing contractor worth hiring from one who is not is whether they diagnose before they price. Damp in a Cypriot house is nearly always water arriving from somewhere — a flat roof, a parapet upstand, a balcony slab edge, a bathroom on the floor above — or condensation forming on an uninsulated concrete frame in January. Different causes, different fixes, very different prices. Beyond diagnosis, three things are checkable on paper before you sign: the company at the Registrar of Companies, insurance certificates with current dates, and a quote that names the cause it is treating.

What can actually be verified

Start with the entity. The Registrar of Companies keeps a public search, so you can confirm the company exists, see the directors and see whether annual returns have been filed. This matters more here than in most trades, because a guarantee is worth what the company behind it is worth. A long guarantee from a business incorporated last year is a piece of paper unless an insurer stands behind it independently, so ask which it is and read the wording rather than the summary. Ask for the insurance certificates too — public liability, employer's liability, current dates, insured name matching the quote.

The diagnosis should be a written record as well. A contractor who has surveyed your house can say where readings were taken, at what depth in the substrate rather than off the surface, on what date, and what they ruled out. Surface meters read salts and finishes as readily as water. Ask for the report — if it is one page with a product name on it, there was no survey.

What you cannot verify is reputation. Praise on a company's own site has no provenance behind it, and this site publishes no ratings or testimonials for anyone. Registration, coverage and time in business can be shown, because each comes from a document. For human evidence, ask for the address of a job finished two or three years ago and go and look at it — damp work only proves itself after a wet season, and the wet months here run November to March.

Registrations that matter

Registrar of Companies. Existence, directors, filing history. A company well behind on returns is telling you how it is run, and how it is run is what handles your stage payments and any guarantee claim in five years.

Contractor registration. Building works above a value threshold must be carried out by a contractor registered in the appropriate class, and the class caps the value of works they may lawfully take on. Internal remedial work usually sits below that line; stripping a whole flat roof covering may not.

ETEK. If the work touches structure — a retaining wall, a roof slab, corroding reinforcement, or the common parts of a block — the engineer specifying it must be registered with the Cyprus Scientific and Technical Chamber. Bringing one in rather than employing one is normal. Refusing to name them is not.

Manufacturer approval. Most membrane, tanking and injection systems carry a product warranty that applies only when an approved, trained applicator installs them. Ask which system is being used, whether the company holds current approval, and to see the certificate and its expiry. This is the registration damp contractors are vaguest about, and it decides whether that warranty exists at all.

Tax Department. Ask for the VAT number and what rate the quote assumes. The reduced rate on a primary residence is conditional and applied for, not automatic on remedial work. The people on your site should also be declared for social insurance.

Questions to ask

Nearly all Cypriot housing built from the 1970s onward is a reinforced concrete frame with blockwork infill under a flat roof, and that one fact explains most of the damp you will ever see in such a house.

1. What is the cause, and how do you know?

   Make them name a mechanism: penetrating water, plumbing, ground moisture or condensation. Then ask what evidence points there and what was eliminated.

2. Where exactly is the water getting in?

   On a flat roof the usual suspects are blocked or undersized rainwater outlets and a parapet upstand where the membrane was never dressed high enough. On a balcony it is the slab edge and the threshold. Ask them to show you, outside.

3. Could this be condensation instead?

   Concrete columns and beams in an uninsulated frame run cold in winter, and moisture forms on them first — behind wardrobes, in corners, on north walls. Nicosia has the widest temperature range on the island, which sharpens it inland. Tanking a condensation problem only moves it; the durable answers are insulation at the cold bridge, extraction, and steadier heating.

4. Is the wall or roof actually yours?

   In the 1970s to 1990s blocks that dominate districts like Strovolos, the roof and external walls are normally common property maintained through the common fund. Establish that before you take quotes, not after.

5. Is ground level higher than the floor?

   Semi-basements cut into a slope, garages under the house and terraces repaved upward all put earth against a wall never designed to hold water back.

6. Is this salt rather than water?

   On the coast at Kato Paphos, salt-laden air and salts already in the masonry hold moisture and bloom back through paint, so ordinary render and emulsion fail. Near the salt lake at Oroklini, humidity alone changes the specification.

Ingress shows itself in the wet months while roof repairs need dry weather, so survey and repair often sit in different seasons. Ask what the start date depends on, and who you ring when something is wrong.

What a good quote looks like

A rate per metre is a starting point, not an answer. The same wall costs differently depending on how much render comes off, whether access needs scaffold, whether the cause is treated outside or resisted inside, and how far the making good goes.

A quote you can use has all of this in it:

• The diagnosis restated in one line, so the quote says what it is treating.
• Quantities: linear metres of wall, square metres of tanked or membrane area, number of rainwater outlets, area of render coming off.
• The named system and its specification, not the word "waterproofing".
• Preparation and disposal, and the drying period expected before replastering.
• Making good and decoration, priced or explicitly excluded.
• Access: scaffold, roof access, and whether the block's permission is needed.
• The guarantee — length, who stands behind it, what voids it, whether it transfers on sale.
• The VAT position, and exclusions listed.
• Payments tied to completed stages rather than calendar dates, and a retention held until the defects period ends.

Get three quotes and give all three the same written description of the problem and the same access. If one prices injection, one prices a roof membrane and one prices ventilation, you have three opinions rather than three quotes — and that is the moment to pay an engineer for an independent diagnosis. Our damp proofing project guide sets out the sequence, the projects index covers the related work that often happens at the same time, and the district pages show which companies cover your area.

Warning signs

A price well below the others is rarely efficiency. In damp work it is usually a narrower scope, and what is missing is normally the external cause, the render replacement or the making good. Others worth stopping for:

• A quote given without an inspection, or after a few minutes with a surface meter.
• One remedy for every symptom. A company treating every damp wall on the island with the same product has not diagnosed yours.
• A free survey from a company that sells only one system. That is a sales visit.
• A guarantee longer than the company has existed, with no insurer behind it.
• Internal tanking proposed while the roof outlet outside is visibly blocked. Water that is still arriving has to go somewhere.
• Work proposed on a shared roof or facade without the management committee.
• Cash only, or no VAT number.
• A promise that the wall will be dry and painted next week. Sealing moisture behind new plaster is how a repair fails twice.

Common questions

Is rising damp common in Cyprus?

Far less than the marketing suggests. Damp low down a wall here is more often a leaking supply or waste pipe, splash-back off a hard terrace, a planter built against the wall, or ground level that has crept above the internal floor slab. All four cost less to fix than a chemical course, and none of them are fixed by one. Insist they are ruled out first.

Why does the damp only appear in winter?

Because rainfall is concentrated in the November to March months, and because those are also the months when uninsulated concrete runs cold enough for condensation. Both causes can be present and they need telling apart. A survey done in August is largely inference, so ask what the contractor did to account for the season.

Does damp proofing need a permit?

Internal remedial work normally does not. Replacing a roof covering, altering structure, or working on a traditional building can. Check with the district or municipal authority before committing — unauthorised work follows the property, not the contractor.

Who pays in an apartment block?

Where the roof and external walls are common property, the cost falls to the common fund and the committee has to agree it. Putting a contractor on the shared roof privately creates a dispute, and can leave you paying twice when the block later repairs the roof properly.

Will a dehumidifier solve it?

It manages condensation while it runs. It does nothing about water coming in.

How long before I can redecorate?

That depends on how wet the wall is, how thick the masonry is, and which render goes back on. Ask for the expected drying period to be stated in the quote, with what happens if it takes longer. Decorating early is the most common reason a completed repair looks like a failed one.

Is a coastal property different?

Yes. Salt-laden air drives salts into render and paint, so salt-resistant systems and marine-grade fixings are the standard specification rather than an upgrade. Where sea air has reached the reinforcement and the concrete cover is spalling, that is a structural matter for an engineer, not a coat of paint.
