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.

Façade joints in Castellar del Vallès: where the water gets in

In areas such as Centre, Casc Antic and Eixample, with winters that can be cold and hot summers, façades expand and contract a great deal, and rigid sealant ends up breaking. We choose polyurethane or MS polymer sealants that take up that movement.

On façades in areas such as Els Pedrissos and Can Carner, we fit foam backer rod of the right diameter so the sealant has the correct depth and bonds only to the sides. Where the joint is shallow, we use a bond-breaker tape at the back instead.

We check the joints from outside and the damp from inside, and give you a detailed written quote, per vertical drop or for the whole façade. We also seal joints in nearby areas: Sabadell, Terrassa and Sentmenat.

Frequently asked questions

01

Façade joint sealing at height in Castellar del Vallès: which areas do you cover?

We do this work in Castellar del Vallès, in areas such as Centre, Casc Antic, Eixample, Els Pedrissos, Can Carner, Aire-sol, El Balcó de Sant Llorenç and Can Font, and also nearby: Sabadell, Terrassa and Sentmenat. Before starting we visit the property and prepare a detailed written quote.

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.
