Verified handyman network in Barcelona

We carry out waterproofing in Sants-Badal. We visit the property, assess the job, give you a clear price, and start. Yes, in houses with rear galleries or interior patios typical of the old town. We clean pipes, replace old downpipes, and repair waterproofing when there are leaks.

How we work

We start with ceilings, lights, air ducts, and the tops of wardrobes, where the finest dust accumulates. We then move to walls, doors, frames, skirting boards, radiators, and window tracks. Next is interior and exterior carpentry, 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.

When to call for waterproofing in Sants-Badal

Specific to properties on the seafront. Saltpetre deposits on external walls, penetrating with moisture. It emerges as it evaporates, forming white or bluish patches that peel paint from the inside. The 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 through. 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 exposed to north-facing facades that get colder in winter. It manifests as water droplets on windows, cold corners of rooms, and black mould spots in cold areas of walls. This is dampness that rises from the ground through walls by capillary action of porous materials. It appears 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 is typical in old ground-floor properties, especially in areas with a high water table near the sea.

Materials and brands

No, we choose the product compatible with each material (gres tiles, marble, microcement, parquet) after a 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 tools, long drills, SDS-MAX bits, heavy rotary hammers, because without them, an installation that would take half a day in another city could take two days if you lack the correct equipment. A standard 70-90 m² flat usually takes between half a day and a full day depending on the condition and amount of debris. A full renovation takes longer than a simple repaint.

Indicative price

The price for waterproofing in Sants-Badal typically ranges between €170 and €5000. The final figure depends on the condition of the property, materials, and working time. We always provide a fixed quote before starting. The result is a home 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. We carry out a free preliminary assessment to give you a fixed price based on the area and condition. Masonry work leaves more mess than a simple paint change. All work comes with a 30-day guarantee. It depends on the linear meters of affected wall. We provide a fixed quote after a diagnostic visit, with no obligation.

Frequently asked questions

How to distinguish rising damp from water ingress?
Rising damp: patches move up from the ground to a height of one metre, leaving white efflorescence. Water ingress: patches descend from ceilings or high corners, coinciding with rain.
How much does chemical injection cost?
It depends on the linear meters 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 move furniture away from the affected wall. We work with protective sheeting to minimise dust.
Do you paint with breathable products?
Yes, we use a specific paint system for damp walls: anti-salt sealant primer, breathable microporous paint that allows the wall to breathe.
