De Kitbaas. Premium sealant work as the signature under your interior.

About De Kitbaas

You don't just let anyone into your home. We understand that better than most.

Sealant work is often seen as a quick final touch. Yet technique and appearance come together at the connection between materials. The wrong sealant type, insufficient preparation or an uneven line shows immediately — and can cause joints to stain or lift sooner.

De Kitbaas is not a general handyman company — we specialise in sealant work. We look at application, substrate, movement, material choice, colour and finish. With more than 10 years of experience we know what good sealant work depends on and where it often goes wrong in practice.

From a bathroom in Amsterdam to a new-build home in Amstelveen or a renovation in Haarlem: we work carefully, communicate clearly and leave the workspace tidy. The result should not only look neat, but also suit the situation technically.
