Waterproofing and damp treatment in Valencia — fix the cause, not the paint.
A damp stain is a symptom; somewhere above or behind it is a cause. From €390 we diagnose with instruments, treat with membranes and liquid systems, and prove the result with water — instead of repainting the evidence every spring.
In plain terms
Damp always has an address.
Water reaches a wall from five directions — a terrace or roof above, rain through the facade, a wet zone behind the tiles, the ground below, or condensation from the room itself. Each needs a different fix, and the wrong one buys you exactly one dry season. We start with moisture readings, name the cause in writing, then treat it with the system it actually requires.
Diagnosed, localised repair — survey included
Roof, rain, plumbing, ground, condensation — named, not guessed
Terraces proven with standing water before finishes
Paint comes after the fix — never instead of it
How it works
From stain to proven dry.
Survey & readings
Moisture mapped with instruments; the cause named honestly.
Written scope
System, works and one figure — fixed before we start.
The treatment
Membranes, liquid systems or injection — as the cause demands.
Proof & guarantee
Water-tested, photographed and handed over with the warranty.
The price
Waterproofing cost in Valencia — priced by the cause.
Damp treatments from €390 for a diagnosed, localised repair — the survey, the fix and the water test in one written figure. Full terrace membranes and larger systems are itemised per the real scope, fixed in writing before work and never changed without your written approval.

Why VELTORRA Reformas
Treatment as engineering, not exorcism.
Diagnosis before treatment
Moisture readings and water tests first — the cause goes into writing.
The right system
Bituminous or liquid membranes, cementitious tanking, injection barriers — matched to the cause, not the van stock.
Details obsessed
Corners, drains and penetrations — where waterproofing lives or dies.
Proof before finishes
Flood and hose tests while the fix can still be seen and corrected.
Finishes restored
Plaster and paint rebuilt after the wall has dried — in the right order.
The honest comparison
Treating the cause against painting the symptom.
Same stain, two futures. What happens behind the wall decides which one you paid for.
Cause treated
- Survey names the source in writing
- The membrane or barrier the case demands
- Tested with water before closing
- Dry next spring — and the one after
Symptom painted
- Anti-damp paint over a wet wall
- The stain returns with the season
- Salts push through each new coat
- The cause grows quietly behind it
Is this you
The wall is telling you something if…
A ceiling stain returns after every heavy rain
Paint bubbles and salts bloom on a lower wall
The terrace above the bedroom ponds for days
A renovated bathroom still smells of damp
A ground-floor wall feels cold and reads wet
You've painted the same stain twice already

Questions, answered
Waterproofing in Valencia — asked before treating.
How much does damp treatment cost in Valencia?
From €390 for a diagnosed, localised repair — survey, treatment and water test in one written figure. Full terrace membranes and larger systems are itemised per the real scope, in writing before work, and the figure doesn't change without your written approval.
Can you find the leak without opening everything?
Usually — moisture mapping and controlled water tests narrow the source before anything is opened. When opening is unavoidable, we open the minimum, photograph what we find, and the record goes into your file.
Is anti-damp paint ever the answer?
As a finish over a treated cause, it's fine. As the treatment itself, no — the stain returns with the next season and the cause grows quietly behind it. We treat the source first; paint comes after, not instead.
Is rising damp real, or a sales story?
Both exist. Genuine rising damp shows on ground floors as capillary moisture with salt bands, and it's treated with injected barriers or tanking. It's also routinely confused with leaks and condensation — our readings establish which one you actually have before any treatment is quoted.
My bathroom was renovated and still smells damp — why?
Often the wet-zone waterproofing under the tiles was skipped or badly detailed. We test to confirm, and where needed rebuild the shower zone in the right order — sealed, tested, then tiled — coordinated with our bathroom renovation team.
Water is coming in right now — how fast can you come?
Waterproofing is scheduled work, not an emergency call-out — we book surveys Mon–Fri 08:00–19:00 and Sat 09:00–14:00. If water is actively flowing, isolate the supply or ask the building to close the source first; once it's contained, we diagnose properly and fix the cause, not the symptom.
Stains are symptoms. We treat causes.
Send photos of the stain and the room above or behind it — an engineer replies in writing with the likely cause and what it takes to prove and fix it.
