EXTERNAL WALLS

Rain penetration and façade leaks in Alicante

Does an inside wall get wet after rain?

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

Several details can interrupt the wall’s protection

A water-repellent treatment and a crack repair serve different purposes. The condition of the façade decides which approach may help.

01

Porous or damaged finishes

Weathered render and unsuitable coatings can affect how the wall handles water. The substrate must be assessed before treatment.

02

Cracks and joints

We examine visible cracks and material junctions. Signs of movement may require a separate structural assessment.

03

Windows and balconies

Sills, thresholds and junctions can channel water into the building. Access and the affected details shape the intervention.

04

Parapets and coping

Water entering at the top can appear further down. We consider roof-to-wall junctions alongside the visible façade.

Inspection on site

Connect the interior stain with the exterior details

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.

  • Interior and exterior position of the stain
  • Rain direction and timing of the problem
  • Accessible render, joints and window surrounds
  • Access needs and compatible finishing options

One meter reading cannot establish the cause. We compare the readings with the visible pattern, surroundings and history of the problem.

Common questions

Before arranging repairs

Will water-repellent treatment stop every leak?

No. It does not replace the repair of cracks, failed joints or defective construction details.

Could this be condensation?

Yes. Rain penetration and condensation can coexist, so the pattern and history must be checked.

Do you undertake structural façade repairs?

Structural concerns need the relevant assessment. This service focuses on moisture and waterproofing within an agreed construction scope.
