In Amsterdam we see it all: compact bathrooms, lots of corner joints and (especially in older homes) sealant that fails due to moisture or movement. From an apartment in De Pijp to an upstairs flat in Oud-West or a home on IJburg: we seal neatly, cleanly and durably. No project scope. No after-the-fact charges. We determine your fixed price upfront based on photos. That way, you know what's included in the agreed project price — with clear agreements upfront. Send photos and we often schedule based on location, scope and availability.

Sealant work in Amsterdam: what we most often come for

In Amsterdam, sealant joints are heavily used: daily showers in small bathrooms, limited ventilation, and sometimes movement in older homes. We deliver a neat, carefully sealed finish — with materials that fit wet areas and everyday use.

bathtub

Bathroom sealing

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

kitchen

Kitchen sealing

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

square_foot

Skirting boards & gaps

Ideal after painting or flooring: a clean transition between wall and floor (also in apartments).

window

Frames & windows

Draft-proof or carefully sealed: suited to wood, uPVC or aluminium (indoors/outdoors).

construction

Sealant replacement

Old, discoloured or lifting sealant carefully removed. We then clean and degrease the substrate before applying new sealant.

Check & advice

Sending photos = quick clarity. We’ll advise on ventilation, surface and finishing.

Sealant specialist in Amsterdam (districts & neighbourhoods we visit often)

We work in all districts: Centrum, West, Oost, Zuid, Noord, Nieuw-West and Zuidoost. Many requests come from Jordaan, De Pijp, Oud-West, Rivierenbuurt, Watergraafsmeer, Bos en Lommer and IJburg.

Amsterdam is often “lots of joints in very few square meters”. Do you see black spots, cracks or a sealant edge coming loose? Then sealant replacement is usually the fastest way to reduce the risk of moisture problems and moisture damage — especially around showers and countertops.

Frequently asked questions about sealant work in Amsterdam

Practical answers — view our prices, send photos, and we confirm quickly.

How much does sealant work cost in Amsterdam? expand_more

First check our Prices & packages for an initial idea. Then send overview and detail photos. After assessment we confirm the fixed project price for the agreed scope of work in advance.

Can I calculate my price in advance? expand_more

Yes. After reviewing your photos and information, we confirm the project price in advance for the agreed scope of work. If the actual situation differs significantly, we discuss this before carrying out additional work.

Can you remove and replace old (mouldy) sealant? expand_more

Yes. We carefully remove the agreed old sealant, clean and degrease the substrate and apply new sealant suited to the application. Mould-resistant properties can slow mould growth, but good maintenance and ventilation remain important.

Do you offer a warranty on sealant work? expand_more

You get a 2-year warranty on the workmanship and adhesion of sealant applied by De Kitbaas. When you report an issue, we first assess the cause. If it falls under warranty, we repair the affected sealant work at no charge.

About De Kitbaas

De Kitbaas is not a general handyman company — we specialise in sealant work. We look at application, substrate, movement, material choice, colour and finish. We communicate clearly, work carefully and leave the workspace tidy. In Amsterdam you mainly want one thing: it has to look sharp and it has to last. That’s why we work precisely, cleanly and with materials that fit wet areas and intensive use.

Whether it’s a bathroom in Centrum or a kitchen on IJburg — we deliver sealant work as if it were our own home. And yes: a 2-year warranty is simply part of that.
