If the roof is damaged, the entire waterproofing needs renewal with new asphalt felt or a liquid-applied 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 the exterior is watertight 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's why we always start with a technical diagnostic visit before providing any quote. The difference between treating dampness correctly or incorrectly can change the durability of the result between five years and six months.

This is dampness that forms when indoor air saturated with vapour touches a cold surface. Typical in kitchens and bathrooms without adequate ventilation, and also in rooms exposed to north-facing facades that get colder in winter. It manifests as water droplets on windows, cold room corners, and black mould spots on cold wall areas. Formal guarantee on the treatment. If the dampness reappears in the same spot, we'll return. The most common mistake with dampness is repainting the affected wall. It works for the first month, and then the dampness returns, worse than before. Now, the new paint creates a barrier trapping water inside the wall. Dampness isn't cured by painting. It's cured by identifying the water source and stopping it at its entry point. Only then do we repair the wall using the appropriate technique and repaint.

No, we select the product compatible with each material (stoneware, marble, microcement, parquet) after prior assessment. This is precisely what prevents scratching or dulling new surfaces. Running a new cable through a forty-centimetre thick old masonry wall is not the same as running it through a plasterboard partition. Here, technicians must know the city and bring the right equipment: long drills, SDS-MAX bits, heavy-duty rotary hammers, because without them, an installation that would take a morning in another city could become two days if you lack the correct tools. Construction dust is very fine and stays suspended. That's why we do several passes from top to bottom and leave the floors for last, so the dust doesn't reappear two days later.

The price for partition walls and masonry in Parets del Vallès typically ranges from €186 to €5400. The final figure depends on the property's condition, materials, and work time. We always provide a fixed quote before starting. Call us, message us on WhatsApp, or request your quote online – we respond in under 10 minutes during business hours. The result is a home ready to move into or hand over to a tenant or buyer, without dust reappearing after two days or residue on windows and taps. We provide a free initial assessment to give you a fixed price based on square metres and condition. Masonry work leaves more residue than a simple paint change. All work comes with a 30-day guarantee.
