Kitchen sealant and worktop sealing

Worktop to wall joints, upstands, splashbacks and the run round an inset sink, sealed with the old line taken out first. £95 on its own.

£95including VAT and the silicone. The full price card

A kitchen worktop joint where a laminate worktop meets a tiled upstand behind an inset stainless steel sink, with a fresh clear silicone line run along it

A kitchen joint fails quietly. Nobody looks behind the kettle, and by the time the sealant along the back of the worktop has gone brown and lifted, water has been running down the back of the units for a while. On a laminate worktop that shows up as a swollen edge that will not go back down.

The work covers the worktop to wall joint, the run behind an upstand or a splashback, the joint round an inset sink or a drainer, and the hob surround where there is one. It is the same method as a bathroom: strip out, clean, dry, seal, tool.

£95 on its own including VAT and silicone. Added to a bathroom booking on the same visit it is £35, because the set up and the kit are already there.

What is included

  • Worktop to wall joint along the full run
  • Upstand and splashback joints, top and bottom
  • Round an inset sink or drainer, and the tap base where it needs it
  • Hob surround where the hob sits in the worktop
  • Old sealant stripped out rather than sealed over
  • Clear or white silicone, or a colour matched to the worktop where one exists
  • Surfaces wiped down and the old material taken away

Sinks, taps and the joint nobody can see

The joint round an inset sink is the one that matters most and the one that gets least attention, because half of it is under the rim where nobody looks. On a laminate worktop that joint is the only thing between standing water and chipboard, and once chipboard is wet it swells and stays swollen.

The clip-down sinks in most kitchens were bedded on sealant when they were fitted, and that bedding is a consumable. If the sink moves at all when you lean on it, the bedding has gone and the sink wants lifting, cleaning and re-bedding rather than a line run round the outside.

Worktop materials change the answer

Laminate is the common case and the one with the most to lose, because the core is chipboard and water damage there is permanent. Solid timber moves seasonally and wants a joint sized for that movement. Quartz, granite and solid surface do not move and take a tighter, neater line.

The silicone changes too. A neutral cure silicone goes on natural stone rather than an acetoxy one, because the acetic acid in a standard bathroom sealant can mark some stones and can corrode the fixings behind the joint. It is the sort of detail nobody notices until it is wrong.

The joint behind a kitchen tap

The seal round the base of a mixer tap is the joint that fails first in most kitchens and the one nobody thinks of as a joint at all. Every wash sends water round the base, the tap gets nudged sideways a hundred times a week, and there is usually nothing under it but a rubber washer that went hard years ago.

On a laminate worktop that leak goes straight down into the cut-out edge, which is unsealed chipboard on most kitchens fitted before about 2010. By the time anything shows on the surface the edge of the cut-out has been wet for months.

Sealing round a tap base is part of a kitchen booking and it is worth asking for even when the worktop joint looks fine. If the tap itself is loose the fix is tightening it from underneath rather than sealing round it, and you get told which of the two you have.

On the day

How a kitchen sealant runs

  1. Clear the run

    Everything off the worktop and back from the wall. Ten minutes that decides whether the bead is straight, because a joint sealed round a toaster is a joint sealed badly.

  2. Cut the old line out

    Blade along the tile or the painted wall, plastic tool on the laminate or the stone. Old kitchen sealant is usually thinner and harder than bathroom sealant and it comes off in pieces rather than ribbons.

  3. Degrease, then dry

    A kitchen joint has cooking grease in it as well as residue, and silicone will not bond through grease. Degreaser first, then a solvent wipe, then dry.

  4. Seal and tool

    Masked both sides, run in one pass, tooled to a shallow concave finish so nothing catches crumbs, tape pulled wet.

  5. Give it the evening

    Wipe the worktop rather than washing it down for the rest of the day, and keep water off the joint overnight. Normal use the next morning.

Kitchen sealant and worktop sealing questions

Can you match the sealant to the worktop?

Usually. Clear, white, grey, black and a couple of stone tones are all available off the shelf, and clear is what most kitchens end up with because it disappears against any colour. Tell us the worktop when you book and the right cartridge comes with the van.

The worktop has swollen at the sink. Can sealing fix it?

No. A swollen laminate edge is chipboard that has taken water and expanded, and it does not go back. Sealing the joint stops it getting worse from that point on, which is worth doing, but the edge stays as it is. Replacing that worktop section is a separate job and Hembury Contracting can price it.

Do you do the joint behind the hob?

The sealant joints round it, yes. Nothing on this site is gas work. If a hob has to be lifted out to get at a joint properly, and it is a gas hob, that is a Gas Safe engineer's job and it will be said plainly rather than worked around.
