Sealing facade joints with a sealant gun

Façade joint sealing at height in Sant Andreu.

We remake the joints that let water into façades of buildings and houses in Sant Andreu, working suspended from the roof with no scaffolding on the pavement.

5/5 · Google reviews

When do the joints need sealing?

  • Damp inside next to the façade
  • Cracked or detached sealant
  • Open joints between panels
  • Water getting in around windows

What joint sealing includes

  • Joint-by-joint inspection

    Working from the ropes, we find cracks, debonding and empty joints.

  • Removing old sealant

    We cut out and clean the old sealant until the edges are sound.

  • Backer rod

    A foam rod gives the sealant the right depth.

  • Primer

    Primer on the edges so the sealant bonds properly to the substrate.

  • Elastic sealant

    Polyurethane or MS polymer that moves with the façade.

  • Window and panel joints

    Window perimeters, expansion joints and junctions between panels.

Old sealant, new joint: what we check at height

In 1960s and 70s buildings in areas such as Sant Andreu and La Trinitat Vella, many façades have joints between panels or against the next building that were sealed only once, with sealant now hard and detached. We redo them from the roof, with no scaffolding in the street.

Around windows in homes in areas such as La Sagrera, Navas and El Congrés i els Indians, we first check whether water is getting in through the joint or through the frame itself. We seal the frame-to-wall junction and check the sill, which is often where the leak really starts.

A site manager coordinates the rope access team with the residents and, when we finish, we remove sealant offcuts and tape from the façade and pavement. We also travel to the surrounding areas: Nou Barris, Horta-Guinardó and Sant Martí.

Frequently asked questions

01

Façade joint sealing at height in Sant Andreu: which areas do you cover?

We work in Sant Andreu in areas such as Sant Andreu, La Trinitat Vella, La Sagrera, Navas, El Congrés i els Indians, El Bon Pastor and Baró de Viver, and also nearby: Nou Barris, Horta-Guinardó and Sant Martí.

02

Which sealant do you use for façade joints?

Elastic polyurethane or MS polymer sealants, suitable for exterior use and paintable. We choose according to the façade material and the movement the joint has to absorb.

03

Can you seal just the area where water gets in?

Yes. If the problem is localised, we seal the affected vertical drop. During the visit we also check nearby joints, as they are usually the same age and equally worn.

04

Why not just apply new sealant over the old?

Because new sealant does not bond well to old sealant or dust. The old one has to be removed, the edges cleaned, a backer rod fitted and primer applied; that way the joint can move without opening again.
