Porous or damaged finishes
Weathered render and unsuitable coatings can affect how the wall handles water. The substrate must be assessed before treatment.
Water coming through exterior walls
An inside wall becomes wet after rain, but there is no obvious crack? We assess the façade, accessible joints, window surrounds and balconies. The visible stain may be below or beside the actual entry point.
Initial guidance from photos is free. An on-site technical visit costs €85 including VAT, booked and paid in advance. The full €85 is credited if we carry out the subsequent work.

Understanding the problem
A water-repellent treatment and a crack repair serve different purposes. The condition of the façade decides which approach may help.
Weathered render and unsuitable coatings can affect how the wall handles water. The substrate must be assessed before treatment.
We examine visible cracks and material junctions. Signs of movement may require a separate structural assessment.
Sills, thresholds and junctions can channel water into the building. Access and the affected details shape the intervention.
Water entering at the top can appear further down. We consider roof-to-wall junctions alongside the visible façade.

Inspection on site
Photos of both sides and the timing after rain help narrow the investigation. Safe access must be agreed; specialist access equipment is not assumed to be included in the basic visit.
One meter reading cannot establish the cause. We compare the readings with the visible pattern, surroundings and history of the problem.

No. It does not replace the repair of cracks, failed joints or defective construction details.
Yes. Rain penetration and condensation can coexist, so the pattern and history must be checked.
Structural concerns need the relevant assessment. This service focuses on moisture and waterproofing within an agreed construction scope.
Services
Water can travel through a building before a stain appears. Explore the other possible sources.
Does the damp return after repainting? Rising damp, rain penetration and condensation need different responses. We investigate the pattern before proposing treatment for your home on the Alicante coast or in the Vinalopó area.
See how we can help →02 / Leaking terraces, balconies and roofsWater coming through the ceiling when it rains? The entry point is not necessarily directly above the stain. We assess roof and terrace details before deciding whether a local repair or a wider waterproofing system is appropriate.
See how we can help →03 / Basement walls and below-ground moistureDoes a wall below ground stay wet or leak after rain? We assess the contact with the ground, wall-to-floor joints and accessible drainage. Waterproofing from inside is only proposed when the substrate and water conditions allow it.
See how we can help →04 / Pool water loss and waterproofingAre you topping up the pool repeatedly? We assess construction and waterproofing issues around the shell, joints and embedded fittings. Hidden pipe leaks require different checks and are not included in this service.
