Real projects, filmed as we work. See how we prepare, match colours and finish the joints.

  • Kitchen

    Three sealant lines. One neat corner.

    Old sink sealant replaced and the joints carefully finished in textured grout grey.

  • Kitchen

    Neat joints along uneven tiles

    The seal follows the shape of the tiles, with a colour matched to the grout.

  • Kitchen

    Matching the kitchen wall

    Here the sealant matches the wall rather than the worktop for a subtle finish.

  • Kitchen

    A fresh seal along the worktop

    Remove the old sealant, clean thoroughly and reseal the joint neatly.

What we seal in the kitchen

We finish the joints along your worktop, backsplash and sink neatly. The sealant and colour need to suit the materials, not just look good.

Your kitchen is the heart of your home. A place where you live, cook and laugh. But water around the sink and grease splashes behind the stove can damage your worktop.

From sink to plinth: we assess the visible joints and use sealant suited to each application.

Around the sink

A neat joint around the sink helps keep water from entering open gaps or getting under the visible edge.

Worktop & backsplash

A clean seam between your worktop and wall. Easy to clean and no gap where crumbs disappear.

Behind the stove

Around a stove or cooktop, we follow the installation instructions and check the distance from heat. We only seal joints where the application and temperature allow it.

Kitchen plinths

We first check whether the kitchen plinth can be sealed. Ventilation, access to appliances and the floor's movement space must be preserved.

Replace old sealant

We remove old or loose sealant carefully, use a suitable cleaner on the bonding surfaces and prepare them for the new sealant.

Colour matching for your job

We choose a colour to suit the worktop, backsplash and grout. An exact, invisible match is not always possible.

Photos first, then a fixed project price

Send an overview of the worktop and close-ups of the sink, backsplash, corners and existing sealant. We assess the situation and confirm the project price before starting.

Clear & personal

No surprises. Clear agreements and direct contact via WhatsApp.

Photo check

Overview and close-up photos help us assess the visible joints and the condition of existing sealant.

Carefully matched colour

We choose a colour that blends with the worktop, backsplash and grout as closely as possible.

Fast & clean

We work carefully around your kitchen items and leave everything fresh.

2-year warranty

A warranty on the workmanship and adhesion of the sealant we apply.

Why material choice matters in the kitchen

Kitchen joints face moisture, grease, cleaning and sometimes heat. We choose premium sealant to suit each joint and surface.

Easy to clean

We use sealant suited to the kitchen application and normal household maintenance. The cleaner also needs to suit the sealant and worktop.

Suitable for natural stone

For granite, marble or hardstone, we choose sealant suited to that stone. Cleaners, primers and finishing agents must also be compatible to help prevent stains along the edge.

Suited to the application

We assess moisture, surfaces and distance from heat before choosing the sealant.

Color matching

We match the sealant color to your worktop or backsplash so the joint is nearly invisible.

Protect your worktop

An open or leaking joint can let water reach a moisture-sensitive worktop, leading to swelling or damage. Have the joint checked if you notice these signs:

  • The sealant is pulling away or cracking.
  • Black marks that remain after suitable mild cleaning. They do not automatically mean the joint leaks.
  • A persistently greasy or sticky surface. We check the cause and condition of the joint.

How it works

  1. Send a photo of your worktop and the joints to be sealed.
  2. Check your price: view our prices & packages or WhatsApp us. You’ll quickly get a fixed price.
  3. Appointment: we work neatly and explain when the new sealant can handle water, heat and cleaning. Leave the joint alone until then.
  4. Finished: neat sealant work with a 2-year warranty on workmanship and adhesion.

FAQ — kitchen sealing

Why is specific kitchen sealant important?
Kitchen joints face moisture, grease, cleaning and different surfaces. We choose suitable sealant for each joint. Use a cleaner compatible with both the sealant and worktop; stronger is not automatically better.
I have a natural stone worktop. Can it stain?
Yes, an unsuitable product can stain the edges. For natural stone, we choose sealant, cleaner and any primer to suit the stone. For composite worktops, we also follow the worktop manufacturer's instructions.
What does kitchen sealing cost?
Start with the Prices & Packages and send overview and close-up photos. After assessing them, we confirm a fixed project price for the agreed work before starting.
Do I need to clear my worktop?
Please clear the area around the edges (coffee machine, knife block). That way we can work cleanly and finish it best.
Do you provide a warranty?
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.
