We provide a fixed quote after a diagnostic visit, with no obligation. The treatment requires addressing the source of the water, not just the interior symptom. If the roof is degraded, the entire waterproofing needs to be renewed with new asphalt felt or a projected liquid polyurethane system. If the facade has structural cracks, they are sealed with elastic mastic and repainted with specific facade paint that covers micro-cracks. Only after ensuring exterior watertightness do we repair the interior wall.

Specific to beachfront homes. Saltpetre deposits on exterior walls, penetrating with moisture. It emerges when evaporating, forming white or bluish stains that cause paint to peel from within. Treatment involves washing with specific chemical products, neutralising remaining salts with anti-efflorescence products. Application of a siloxane-type paint system that allows the wall to breathe without letting water pass through. This is moisture that forms when indoor air laden with vapour touches a cold surface. Typical in kitchens and bathrooms without adequate ventilation, also in rooms exposed to north-facing facades that cool down more in winter. It manifests as water droplets on windows, cold corners of rooms, black mould spots in cold areas of walls. This is moisture that rises from the ground through walls via capillary action in porous materials. It manifests as a damp patch on the ground floor up to one meter high, 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.

We guarantee chemical injection for 5 years in writing. The reality is that it lasts 15-20 years or more if the treatment is done correctly and no new source appears. For chemical injection and interior wall repair, yes, at least remove furniture from the affected wall. We use protective plastics to minimise dust. Capillarity: stain rises from the ground, up to one meter high, white efflorescence. Filtration: stain descends from the ceiling or high corners, coincides with rain.

The price for insulation in Gràcia (Sabadell) usually ranges between 208 and 2970 euros. The final figure depends on the property's condition, materials, and working time. We always provide a fixed quote before starting. We work with gas, oil, and electric boilers, traditional radiators, underfloor heating, and smart thermostats. Each home has its own story. A village house near the square doesn't heat up the same way as a chalet on the outskirts surrounded by orchards. That's why our professionals always start with an honest assessment before proposing solutions. We explain what you need, what to expect, and how much it costs, with no surprises on the final bill or unnecessary parts added to the quote.
