Damp Treatment in Alicante — We Fix the Cause, Not Just the Stain
We carry out damp treatment in Alicante by tackling the cause, not just the stain: rising (capillary) damp, condensation, leaks and salts. We install injection barriers, ventilation systems and anti-damp renders, then re-plaster and repaint. Backed by a 2-year guarantee across the Costa Blanca.

Stains, mould and blistering paint are symptoms; the key is diagnosing the source. Older coastal apartments often suffer several kinds of damp at once: capillary damp rising through the walls from the ground, condensation from poor ventilation, and salts that crystallise and blow the plaster off.
With over 15 years of experience and our own team, we measure the moisture level and locate the source before proposing anything. That is the only way to make the fix last: painting over active damp merely hides it for a few months.
Depending on the case we inject a chemical barrier against rising damp, improve ventilation to stop condensation, treat the salts and re-render with breathable mortars. We finish with anti-mould paint to leave the wall healthy. For overseas owners we send photo reports at each stage.
What's included
Diagnosis with moisture readings
We locate the source of the damp and measure its level before proposing any treatment.
Anti-capillary barrier
We inject a chemical barrier at the base of the wall to cut off damp rising from the ground.
Condensation control
We improve ventilation and insulate the cold spots where moisture forms.
Salt treatment
We neutralise and contain the salts that crystallise and destroy the plaster.
Breathable re-render
We renew the wall with renovating mortars that let the surface breathe.
Anti-mould paint
We finish with fungicidal paint that stops stains and mould coming back.

Frequently asked questions
How much does damp treatment cost?
It depends on the type of damp, the area affected and whether we must re-render and repaint. A patch of condensation is not the same as rising damp across several walls. That is why we diagnose first and fix the price after. Request a free, no-obligation personalised quote.
Why do the stains come back after I painted the wall?
Because paint covers the symptom but does not cut off the cause. If damp keeps rising or condensation persists, stains, mould and flaking return within months. The lasting fix is to treat the source before repainting.
How do I know if it is rising damp or condensation?
Rising damp appears low on the walls, as a band of moisture and salts creeping up from the floor. Condensation forms on ceilings, corners and cold, poorly ventilated areas, often with black mould. We measure and confirm which it is during the visit.
Do you have to hack off the whole wall?
Not always. Where the plaster is badly damaged by salts it is best to strip it back to brick and re-render with breathable mortar. If the damage is only surface-deep we treat just the affected area. We assess this at the visit to remove the minimum necessary.
Is the treatment guaranteed?
Yes. The anti-capillary barriers and anti-damp systems we install carry a 2-year guarantee on our workmanship. Real durability also depends on keeping adequate ventilation, which we explain to you on completion.
