Floor joint sealing in Lisson Grove
The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk generally cracks where there’s movement, so we use a flexible sealant that moves with the floor. We’re often asked to deal with caulk that has cracked where the floor moves and gaps at thresholds between rooms, on tiled floors, commercial floors and wet room & bathroom floors.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement, in Lisson Grove as anywhere.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Lisson Grove.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

FAQs for Lisson Grove
Is parking a problem for a job in Lisson Grove?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you cover Lisson Grove for floor joint sealing?
Yes. Our work covers London and the South East, and Lisson Grove is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Do you seal kitchen plinths to the floor?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so we seal them with silicone suited to wet areas.
How soon can the floor be mopped?
You will get the times before we go. That depends on the product, and walking on it generally comes before mopping or wheeled traffic.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
What causes gaps between the floor and skirting?
Movement from drying timber and settling floors pulls the skirting and floor apart. Rigid fillers split, so we use a flexible sealant.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
Joints and finishes in Lisson Grove homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal.
For buildings such as St Paul's Community Church, joints in its floors, skirtings and thresholds need resealing as they wear. Lisson Grove is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Don’t slide heavy items over sealed joints
- Mark off resealed joints in warehouses
- Walk round the room once a year and look at the edges
- Don’t paint over silicone
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.
