Sealant replacement • Prevent leaks • Fresh start

Q: Does removing sealant make a mess?

It can crumble, but we work cleanly. We bring a vacuum and remove all old sealant residue.

Q: Can I remove the old sealant myself?

You can, and it may reduce the cost. Make sure the surface isn’t damaged and all residue is removed. If you’re unsure, let us do it so you have full warranty.

Q: Does insurance cover water damage caused by bad sealant?

Usually not if the cause is poor maintenance. Consequential damage is sometimes covered. Replacing sealant in time with an invoice helps your case.

Q: How long does it take?

Replacement takes longer than applying new sealant. For an average bathroom we are often busy for half a day.

Q: Do you provide a warranty?

Yes, 2-year warranty, provided we removed the old sealant ourselves and could clean the surface properly.

window

Windows (inside/outside)

Old glazing sealant is replaced with a clean, insulating seal.

straighten

Floors & skirting

Dirty sealant along the floor? We restore a clean, fresh line.

Why “just touching up” is a bad idea

We often hear: “Can you just add a thin layer?” The honest answer: No.

check_circleAdhesion: New sealant doesn’t bond well to old sealant. It will fail again quickly.
check_circleMould: If you seal over mould, it keeps growing underneath and comes back worse.
check_circleLeaks: You trap moisture between layers. That’s asking for trouble.

Our approach: Remove everything, chemically clean and degrease the surface, then rebuild. Only this gives you warranty.
