We start with ceilings, light fixtures, air ducts, and the tops of wardrobes, where the finest dust accumulates. We then move on to walls, doors, frames, skirting boards, radiators, and window tracks. Next, interior and exterior woodwork, windows inside and out, taps, and sanitaryware. We finish with the floors, which are done last as they receive everything that falls during the process. Thorough vacuuming, mopping with a neutral cleaner, and, if necessary, a second mop to remove the last traces of construction dust. Rising damp, roof leaks, internal condensation, and salt-petre efflorescence. Diagnosis before action.

Formal guarantee on the treatment. If the damp reappears in the same spot, we'll return. The most common mistake with damp is repainting the affected wall. It works for the first month, then the damp reappears, worse than before. The new paint creates a barrier trapping water inside the wall. Damp isn't cured by painting. It's cured by identifying the water's origin and stopping it at its entry point. Only then do we repair the wall with the appropriate technique and repaint. There are four types of damp we commonly see in 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 diagnostic technical visit before quoting anything. The difference between treating damp correctly or incorrectly changes the result's durability from five years to six months.

Technically, this means we work almost exclusively on bungalows with similar installations. The same type of fuse box is repeated in dozens of homes, the same type of electric water heater installed by the original developer, the same air conditioning from the 2000s now on its second life. For an electrician or plumber, this is a huge advantage; diagnosis is faster, and common parts are kept in stock. The total intervention time per fault is reduced. The most requested service is the replacement of electric water heaters at the end of their useful life. The La Herrada bungalows were built between the 90s and 2000s with 100 or 150-litre heaters that have now run their course after twenty or twenty-five years with hard water. Replacement with a new model from a quality brand, Junkers, Cointra, Edesa, with a sacrificial anode to extend the useful life. Half-day job per unit. No, we choose the product compatible with each material (stoneware, marble, microcement, parquet) after prior assessment. This is precisely what prevents scratching or dulling new surfaces.

The price for interior painting in Castellar del Vallès typically ranges between €114 and €2,700 as an indicative reference. The final figure depends on the property's condition, materials, and work time, and we always finalise it after seeing photos or — if you prefer — a site visit, with no obligation. In the area, the market reference is around €450 for similar jobs; we are usually below this when the property's condition allows. The result is a house ready to move into or hand over to a tenant or buyer, with no dust reappearing in two days or residue on windows and taps. We provide a free initial assessment to give you a fixed price based on the square metres and condition. Any building work leaves more mess than a simple paint change. All work comes with a 30-day guarantee. It depends on the linear metres of wall affected. We provide a fixed quote after a diagnostic visit, with no obligation.
