Verified handyman network in Barcelona

We build partition walls and masonry in Granollers. We visit the property, assess the work, give you a clear price, and get started. Yes, a specific paint system for damp walls: anti-salt primer sealer, breathable microporous paint that allows the wall to breathe.

How we work

Call us, message us on WhatsApp, or request your quote online — we'll reply in under 10 minutes during business hours. The bungalows in La Herrada have repetitive installations, the same type of fuse box, water heater, and air conditioning in many homes. This reduces diagnostic time and allows us to carry common parts in stock. We start with ceilings, light fittings, air ducts, and the upper parts of wardrobes, where the finest dust accumulates. We then move to walls, doors, frames, skirting boards, radiators, and window tracks. After that, interior and exterior carpentry, windows inside and out, taps, and sanitary ware. We finish with the floors, which are done last as they receive everything that falls during the process. Thorough vacuuming, mopping with a neutral product, and, if necessary, a second mopping to remove the last traces of construction dust.

When to call for partition walls and masonry in Granollers

Specific to frontline sea properties. Saltpetre deposits on exterior walls and penetrates with moisture. It emerges as water evaporates, forming white or bluish stains that cause paint to peel from within. The treatment involves washing with specific chemical products, neutralising remaining salts with anti-efflorescence products, and applying a siloxane-type paint system that allows the wall to breathe without letting water in. This is dampness that forms when indoor air, saturated with vapour, comes into contact with a cold surface. Typical in kitchens and bathrooms without adequate ventilation, also in rooms facing north-facing facades which get colder in winter. It manifests as water droplets on windows, cold corners of rooms, and black mould stains in cold wall areas. This is dampness that rises from the ground through walls due to the capillary action of porous materials. It shows up as a damp stain on the ground floor up to a 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.

Materials and brands

The most requested 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 worn out after twenty or twenty-five years of use with hard water. We replace them with new models from quality brands such as Junkers, Cointra, Edesa, with a sacrificial anode to extend their lifespan. This is a half-day job per unit. Technically, what this means is that we work almost exclusively on bungalows with similar installations. The same type of electrical fuse box is repeated in tens of homes, the same type of electric water heater installed by the original developer, the same air conditioning from the 2000s already in its second life. For an electrician or plumber, this is a huge advantage; diagnostics are faster, and common parts are kept in stock. The total intervention time per fault is reduced. San Miguel de Salinas is an inland municipality about fifteen kilometres from Torrevieja, in the Vega Baja region. It has about ten thousand inhabitants and a mixed profile of Spanish residents and foreign owners who sought to move away from saturated coastal developments. This intermediate position has a specific technical consequence. The local supply of professionals is limited; the self-employed workers here do not have as much competition as in Torrevieja or Orihuela Costa, and the average service quality is uneven. Some professionals are excellent, we know them. Others take advantage of the lack of alternatives to do quick, non-guaranteed jobs.

Indicative pricing

The price for partition walls and masonry in Granollers typically ranges from €186 to €5400. The final figure depends on the property's condition, materials, and working time.

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 or residues on windows and taps.

Frequently asked questions

How to distinguish rising damp from water ingress?
Rising damp: a stain that rises from the ground up to a metre in height, with white efflorescence. Water ingress: a stain that descends from the ceiling or high corners, coinciding with rain.
How much does a chemical injection cost?
It depends on the linear metres of affected wall. We provide a fixed quote after a diagnostic visit, with no obligation.
How long does the treatment last?
We guarantee chemical injection for 5 years in writing. In reality, it lasts 15-20 years or more if the treatment is done correctly and no new source appears.
Do I need to empty the room?
For chemical injection and interior wall repair, yes, at least remove furniture from the affected wall. We work with protective plastics to minimise dust.
Do you paint with breathable products?
Yes, a specific paint system for damp walls: anti-salt primer sealer, breathable microporous paint that allows the wall to breathe.
