It depends on the linear metres of affected wall. We provide a fixed quote after a diagnostic visit, without obligation. The treatment requires intervening at the origin of the water, not just the interior symptom. If the roof is degraded, the entire waterproofing must be renewed with new asphalt felt or a projected liquid polyurethane system. If the façade has structural cracks, they are sealed with elastic putty and repainted with specific façade paint that covers micro-cracks. Only after guaranteeing external watertightness do we repair the interior wall. There are four types of dampness we commonly see on the Costa Blanca, each with a different cause, diagnosis, and treatment. Confusing them inevitably leads to ineffective treatments and wasted money. That is why we always start with a technical diagnostic visit before quoting anything. The difference between treating dampness well or poorly changes the durability of the result from five years to six months.

This is humidity that forms when warm, moisture-laden indoor air touches a cold surface. Typical in kitchens and bathrooms without adequate ventilation, also in rooms exposed to north-facing façades that cool more in winter. It manifests as water droplets on windows, cold room corners, and black mould stains on cold wall areas. This is humidity that rises from the ground through walls due to capillary action in porous materials. It manifests as a damp stain on the ground floor up to one metre high from the floor, often with white efflorescence (salts that crystallise as water evaporates). It is typical in old ground-floor homes, especially in areas with a high water table near the sea. The most common mistake with dampness is repainting the affected wall. It works for the first month and then the dampness reappears, worse than before. Now the new paint creates a barrier that traps water inside the wall. Dampness cannot be cured by painting. It is cured by identifying the source of the water and stopping it at its entry point. Only then do we repair the wall with appropriate techniques and repaint it.

The bungalows in La Herrada have repetitive installations, the same model of electrical panel, water heater, and air conditioning in many homes. This reduces diagnostic time and allows us to keep common parts in stock. Technically, this means we work almost exclusively in bungalows with similar installations here. The same model of electrical panel is repeated across dozens of houses, the same type of electric water heater installed by the original developer, the same air conditioning from the 2000s already on its second life. For an electrician or plumber, this is an enormous advantage; diagnostics are faster, and common parts are kept in stock. The total intervention time per breakdown is reduced. The most demanded service is the replacement of electric water heaters at the end of their useful life. The bungalows in La Herrada were built between the 90s and 2000s with 100 or 150-litre heaters that are now exhausted after twenty or twenty-five years in hard water. Replacement with a new model from a quality brand like Junkers, Cointra, or Edesa, with a sacrificial anode to extend its lifespan. A half-day operation per unit.

The price for communal painting in Poblenou (Sabadell) typically ranges from 144 to 2925 euros. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. The result is a house ready to move into or to hand over to a tenant or buyer, with no dust reappearing after two days, nor residues on glass and taps. We offer a free preliminary assessment to give you a fixed price based on square footage and condition. A masonry job leaves more residue than a simple paint change. All work comes with a 30-day warranty. Call us, write to us on WhatsApp, or request your quote online — we will respond in less than 10 minutes during business hours.
