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.

Façade joints in Castelldefels: where the water gets in

On houses on residential estates in areas such as Centre, El Castell – Poble Vell and Muntanyeta, the joints that fail most are around large windows, terraces and wall-to-slab junctions. We check each one and remake it with backer rod and elastic sealant.

Around windows in homes in areas such as Montmar, Bellamar and Les Botigues, 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.

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: Gavà, Viladecans and Sitges.

Frequently asked questions

01

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

We work in Castelldefels in areas such as Centre, El Castell – Poble Vell, Muntanyeta, Vista Alegre, Can Vinader, Can Roca, Els Canyars and Montmar, and also nearby: Gavà, Viladecans and Sitges.

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.
