Waterproofing of Nou Barris facades: signs that a leak will get worse
In many communities in Nou Barris the problem starts the same way: a small damp spot, a wall that starts to darken or a leak that only appears when it rains heavily.
And almost always the same thing happens: the community thinks it can still wait.
The problem is that by the time the water gets into the facade, the deterioration has usually already started much earlier. Acting in time often makes the difference between a timely intervention or a much more costly rehabilitation.
Detect before repair
Before waterproofing a facade, we check cracks, joints and points where water may be entering.
The objective: to act in the right place without mounting a major work if it is not necessary.



How leaks appear on a facade
In many old buildings in Nou Barris, the facade has been exposed for decades to rain, humidity, temperature changes and natural wear of materials.
With the passage of time, the coating loses its protective capacity and vulnerable points begin to appear.
The most common areas where the problem starts are usually:
- Deteriorated joints.
- Small cracks.
- Balconies and material encounters.
- Aged cornices and seals.
The problem is not always detected from the outside. Often the first sign appears inside a house, when moisture has been entering from the facade for some time.

Signs that the leak will continue to grow
There are very clear symptoms that indicate that moisture is already advancing inside the facade. In Verticals Barcelona we see many communities that wait too long thinking that the problem is still small.
Dark spots or persistent moisture
When a wall maintains constant humidity, water usually continues to enter from the exterior .
Peeling or chipping paint
Moisture eventually pushes the interior coating and deteriorates paint and finishes.
Musty odor
Particularly common in interior courtyards or houses close to the facade.
Small cracks that increase
Many leaks start in seemingly small cracks. Over time, water enlarges the problem.
Leakage after heavy rains
One of the clearest signs of failure in exterior waterproofing. If it appears with rain and takes days to dry, it is advisable to check the facade.
The most common mistake in many communities
Many communities try to solve the dampness by painting the interior wall or repairing only the visible area.
The problem is that this does not eliminate the source of the leak.
Painting the interior wall
It may improve the appearance for a few weeks, but if water enters from the facade, the problem will continue to advance from behind.
Locate the entry point
Before intervening, it is advisable to check joints, cracks, joints, balconies and areas where the exterior waterproofing has failed.

In Verticals Barcelona we see many interventions where the humidity returns because never acted on the real point of entry of water.
This is why it is so important to correctly locate the origin before intervening.
Why waiting is often more expensive
Many communities delay the intervention because "it does not seem serious yet", "it only affects one house" or "this year it is not time to carry out works".
But water has a problem: it never sits still.
If moisture appears especially after rain and takes days to dry, usually the water is already penetrating from the outside.
Have there been any dampness or leaks in your community?
We can help you locate the real source of the problem before it escalates.
How waterproofing of facades is done in Nou Barris
Each building needs a different solution. That's why the first thing is always to evaluate where water is entering, what material is failing and what areas are affected.
The facade is analyzed to understand if the problem comes from joints, cracks, balconies, cornices or joints.
Before waterproofing, cracks, aged seals or areas that have lost adhesion are corrected.
Solutions appropriate to the material and the level of exposure of the facade are applied.
The ultimate goal is not to seal out moisture: it is to keep water out.
- Sealing of cracks and joints.
- Repair of deteriorated points.
- Application of waterproofing products.
- Protection of the exterior coating.
Vertical work for waterproofing facades without scaffolding
In many buildings in Nou Barris, installing scaffolding means more cost, more time and more inconvenience for neighbors.
That is why the vertical works allow to intervene directly on the affected area by rope access.
- Act only where necessary.
- Reduce intervention times.
- Minimize discomfort.
- Optimize costs for the community.

When to check a facade even if the humidity seems to be small
There is a very common situation: the community waits for the problem to "be serious". And when that happens, the intervention is much more complex.
It is advisable to check a facade when they appear:
- First damp stains.
- Small cracks.
- Punctual leaks.
- Deteriorated paint.
- Areas with water after rain.
Acting earlier often saves the community a lot of money.
Waterproofing of facades Nou Barris with professional appraisal
At Verticals Barcelona we work every week with communities that arrive at exactly the same point: a leak that seemed small ends up affecting more areas of the building.
Therefore, before considering major works, the most important thing is to understand what is really happening on the façade and to act judiciously.
Often a timely intervention prevents much more complex repairs months later.
- Locate the source of the leak.
- Assess the actual condition of the facade.
- Propose the most appropriate solution.
- Act without unnecessary works.
