It depends on the linear meters of affected wall. We provide a fixed quote after a diagnostic visit, with no obligation. The treatment requires addressing the water's origin, not the internal symptom. If the roof is degraded, the entire waterproofing must be renewed with new bituminous sheeting or a liquid-applied polyurethane system. If the facade has structural cracks, they are sealed with flexible sealant and repainted with specific facade paint that covers micro-cracks. Only after guaranteeing external watertightness do we repair the interior wall. Chemical injection, exterior waterproofing, breathable coating, or ventilation depending on the diagnosis.

This is moisture formed when indoor air, laden with vapour, touches a cold surface. Typical in kitchens and bathrooms without adequate ventilation, also in rooms facing north facades which get colder in winter. It manifests as water droplets on windows, cold corners of rooms, and black mould spots in cold wall areas. There are four types of damp we commonly see on the Costa Blanca, each with a distinct cause, diagnosis, and treatment. Confusing them inevitably leads to ineffective treatments and wasted money. That's why we always start with a diagnostic technical visit before quoting anything. The difference between treating damp correctly or incorrectly changes the durability of the result between five years and six months. The most common mistake with damp is repainting the affected wall. It works for the first month, and then the damp reappears, worse than before. Now the new paint creates a barrier trapping water inside the wall. Damp is not cured by painting. It is cured by identifying the water's origin and cutting it off at its entry point. Only then do we repair the wall with the appropriate technique and repaint.

There isn't as much competition here as on the coast, and it shows in the quality of some professionals. We work in Sant Cugat with the same standards as in Torrevieja. San Miguel de Salinas is an inland municipality fifteen kilometres from Torrevieja, in the Vega Baja region. It has about ten thousand inhabitants and a mixed profile between resident Spaniards and foreign owners who sought to move away from saturated coastal urbanisations. This intermediate position has a specific technical consequence. The local supply of professionals is limited; self-employed workers here don't face as much competition as in Torrevieja or Orihuela Costa, and the average service quality is uneven. Some professionals are excellent; we know them. Others take advantage of the lack of alternatives to do quick, guaranteed-free jobs. No, we select the product compatible with each material (gres, marble, microcement, parquet) after prior assessment. This is precisely what prevents scratching or dulling new surfaces.

The price for partition walls and masonry in Les Roquetes typically ranges between €186 and €5,400. The final amount depends on the property's condition, materials, and working time. We always provide a fixed quote before starting. The result is a home ready to move into or hand over to a tenant or buyer, with no dust reappearing after two days or residue on windows and taps. We carry out a free preliminary assessment to give you a fixed price based on the area and condition. Masonry work leaves more residue than a simple paint change. All work comes with a 30-day guarantee. Call us, message us on WhatsApp, or request your quote online — we'll reply in under 10 minutes during business hours.
