The treatment requires addressing the source of the water, not the indoor symptom. If the roof is damaged, the entire waterproofing needs renewing with new asphalt felt or a projected liquid polyurethane system. If the facade has structural cracks, they are sealed with elastic sealant and repainted with specific facade paint that covers micro-cracks. Only after ensuring external watertightness do we repair the interior wall. Rising damp, roof leaks, internal condensation, and saltpetre efflorescence. Diagnosis before action. Chemical injection, external waterproofing, breathable coating, or ventilation according to diagnosis.

The most common mistake with dampness 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 that traps water inside the wall. Dampness isn't cured by painting. It's cured by identifying the source of the water and cutting it off at its entry point. Only then do we repair the wall with the appropriate technique and repaint. 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's why we always start with a technical diagnostic visit before providing any quote. The difference between treating dampness correctly or incorrectly changes the durability of the result between five years and six months. It's dampness that rises from the ground through the walls by capillary action in porous materials. It manifests as a damp patch on the ground floor up to a height of one metre from the floor, often with white efflorescence (salts that crystallise as the water evaporates). It's typical in old ground-floor properties, especially in areas with a high water table near the sea.

For mosaics, especially glass or small natural stone, use transparent white adhesive so it doesn't show through the grout lines. And grout with quality grout because mould in small mosaics is visually unpleasant and difficult to clean later. We only ask that it is of reasonable quality and arrives on site on the scheduled day. We buy wholesale from local distributors. 30-day guarantee on labour and manufacturer's official warranty on materials.

The price for tiling in Cubelles typically ranges between €140 and €3550 as an indicative reference. The final amount depends on the property's condition, materials, and labour time, and we always finalise it after seeing photos or —if you prefer— after a site visit, with no obligation. In the area, the market benchmark is around €550 for similar jobs; we are usually below that when the property's condition allows. Call us, text us on WhatsApp, or request your quote online — we'll respond in under 10 minutes during business hours. C1 cementitious adhesive is the most economical and is sold in 25kg bags at any hardware store. It may be suitable for basic ceramic tiling on dry interior walls. For floors, bathrooms, exteriors, or any modern porcelain stoneware tile with low absorption, you need at least C2, ideally C2TES1 (cementitious, enhanced, with extended open time and reduced slip). The cost difference between C1 and C2TES1 is relatively small, but the difference in durability and resistance to detachment is huge.
