Countertop Joining in Warsaw — Connecting and Sealing Kitchen Worktops

An L-shaped or U-shaped kitchen always means joining two or more worktop sections. The task seems simple: push them together, screw, seal. In practice, it is more involved. A poorly made joint leaves a gap where water seeps in, the chipboard swells, and within six months the seam buckles. We join kitchen worktops across Warsaw — from Ursynow to Targowek — using eurobolts, specialist adhesive, and colour-matched sealant. The result: a flush seam with no lip, fully protected against moisture.

How much does it cost and what affects the price

Current prices for kitchen services are in the table below. The cost of joining depends on the worktop material (laminate, solid wood, composite), the number of joints, whether on-site trimming is needed, and the condition of the walls in the corner. Laminate worktops are pulled together with eurobolts — faster and cheaper. Wood or composite requires specialist adhesive and more precise fitting. Fixings are included in the labour cost. Sealant and adhesive are charged separately if a specific colour or brand is required. Waste removal and material delivery are also extra.

How the on-site work goes

1. You send a photo of the kitchen and describe the task — how many joints, what worktop material, whether there is a corner joint.
2. The technician assesses the scope and gives an approximate price.
3. On site we check the wall geometry in the corner — walls are often not at exactly 90 degrees and adjustment is needed.
4. We mark out and rout slots for eurobolts (for laminate) or prepare surfaces for adhesive (for wood/composite).
5. We apply sealant to the cut edges — this protects against moisture; without it the chipboard will swell within months.
6. We pull the sections together and align them flush — even a half-millimetre lip is noticeable and gets in the way during cooking.
7. We remove excess sealant and check the joint for evenness and tight fit.

Common customer mistakes (and how to avoid them)

• Joining the worktop without eurobolts — vibration and load cause the seam to open within a couple of months.
• Not sealing the cut edges — water enters the chipboard, the worktop swells and buckles.
• Using standard silicone instead of kitchen-grade sealant — it yellows and does not bond well to laminate.
• Pulling the sections together before applying sealant — the inside of the joint can no longer be sealed.
• Not checking the wall angle before installation — the worktop does not sit against the wall, leaving a gap.
• Skipping the joining strip for laminate — the exposed edge is visible and absorbs water.
• Over-tightening eurobolts — the chipboard cracks and a section has to be replaced.
• Cutting the worktop with a jigsaw without a guide rail — an uneven cut means the joint does not align.

What to prepare before the technician arrives

• Confirm the worktop material: laminate (chipboard), solid wood (beech, oak), or composite (quartz, acrylic).
• Photograph the joint area and the overall kitchen layout — send it to the technician in advance.
• Clear the worktop of dishes, appliances, and food — full access to the joint zone is needed.
• If the worktop is not yet installed, place the sections side by side so the technician can start right away.
• Check whether you have a joining strip and eurobolts (if the kitchen was bought as a set, they are usually included).
• Prepare a power socket for tools — a router or drill will be needed.
• Confirm the worktop colour — sealant is matched to the shade; if you need a specific tone, buy it in advance.
• Arrange access to the flat: intercom code, parking, floor number.
• If the walls in the corner are uneven, let us know — it affects the scope of work.
• Remove base units from under the joint area if they block access from below.

A real case from Warsaw

A client in the Bemowo district ordered an L-shaped IKEA kitchen. The worktop was laminate, two sections: 186 cm and 62 cm. When measuring, we found the wall angle was 88 degrees instead of 90. Simply pushing the sections together would not work: a gap would remain against the wall, and the front of the joint would splay apart. We had to trim the end at an angle to compensate for the wall deviation. After that it was the standard procedure: routing slots for eurobolts, applying sealant to the cut edges, pulling tight, levelling. The joint came out tight with no height difference, and the sealant matched the worktop colour. The whole job took about an hour and a half. Takeaway: even in new-build flats the walls are not perfect — always check the angle before joining.

Frequently asked questions

What is a eurobolt and why is it needed?
It is a special draw bolt that pulls two worktop sections together from underneath. Without it the joint relies on adhesive and sealant alone — not enough for a laminate worktop.

Can the worktop be joined without a visible seam?
On laminate the seam will always be visible, but when done correctly it is minimal. On composite (quartz, acrylic) a virtually seamless bond can be achieved with specialist adhesive.

Is sealant really necessary?
Yes. Without sealant, water reaches the chipboard edges and the worktop swells. This is not about looks — it is about longevity.

How long does the joining take?
One joint takes 1 to 2 hours, depending on the material and whether trimming is needed. If the walls are uneven it takes longer.

What’s included in the price?
Labour, fixings (eurobolts), travel within Warsaw. Sealant, adhesive, and joining strips are separate if not supplied by the client.

Can worktops made of different materials be joined?
Technically yes, but the joint will be more noticeable. It is better to use the same material so the pattern and thickness match.

Do you bring eurobolts with you?
Yes, we always carry standard fixings. If you need a non-standard size, let us know in advance.

What if an old joint has started to swell?
It depends on the extent of the damage. If the chipboard has swollen slightly, it can be cleaned out, dried, and re-sealed. If the damage is severe, it is easier to replace the affected section. Call us, send a photo — we will assess it.
