What De Kitbaas does as a specialist sealant company

Sealant work for bathrooms, kitchens, skirting, floors and frames in Amsterdam, Amstelveen, Haarlem and the surrounding area.

Bathroom sealing

Neat sanitary joints along shower, bath, basin and floor. We choose sealant based on moisture exposure, movement, substrate and colour.

Kitchen sealing

Easy-to-clean joints along worktop, splashback and sink, carefully finished in a matching colour.

Skirting, floors, walls & ceilings

Neat connections where floor, skirting, wall and ceiling meet. We choose suitable sealant and respect the floor's required movement space and installation instructions.

Windows & frames

Sealant work along glass and between frames and walls or facades. We match the materials and joint construction to the glazing and frame system, surfaces and expected movement.

About De Kitbaas

You do not let just anyone work in your home. We understand that.

A sealant line should look neat. Preparation, the right sealant and joint construction matter just as much. You cannot always see what is behind that neat line, but it determines how well the sealant adheres and accommodates movement.

De Kitbaas is a specialist in sealant work, rather than a general handyman business. We consider the application, the substrate, expected movement, the right sealant and a colour that suits the room. With more than 10 years of experience, we know what good sealing depends on and where things often go 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 look neat and be technically suited to the situation.

Before you book

What will my job cost?

Send overview and detail photos and your location via WhatsApp. We assess the work and agree a project price for the assessed scope before starting.

Can you match the colour?

We consider the materials and the desired finish. Photos help with preparation; colour and substrate also need attention on site.

When can you come?

Send your location, photos and preferred timing. We discuss availability and confirm the appointment after agreement.

Can you assess the work from photos?

Overview and detail photos help us assess the visible joints. If something is unclear, we ask for more information before confirming the scope.

Does the old sealant need to come out?

When replacing sealant, we remove the old material and prepare the substrate carefully. We assess what your joints need from the photos and the situation on site.

Ready for a clean result?

Send a few clear overview and detail photos and your location via WhatsApp. We'll assess the job and let you know the fixed project price for the agreed scope of work in advance. Measuring yourself is usually not necessary.
