How we handle floor joint sealing in Chalk Farm
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant coloured to suit the grout. If you have gaps opening between the floor and skirting and open joints that fill with dirt, we can help, whatever the surface.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
You get a one-year guarantee, the same in Chalk Farm as everywhere else we work.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Chalk Farm: your questions answered
Is parking an issue for floor joint sealing in Chalk Farm?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you cover Chalk Farm for floor joint sealing?
Yes, Chalk Farm is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Can you use decorators’ caulk instead?
Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
When can I walk on the floor?
That varies with the sealant and the room. We give you the times for walking, cleaning and traffic when we finish so you can plan.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Floor joint sealing around Chalk Farm
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
If you look after a building such as Haverstock School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Rented homes near Kentish Town West station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. Community buildings like St Silas Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a morning or an afternoon for most homes in most cases.

- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and tooled.
- Finally, we check the work and talk you through aftercare.
How to prepare

Why deal with it now?
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job for most homes. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Any old sealant cut out fully, not covered over
- Sealant colour chosen to suit
- Rated 4.9 stars on Google
- More than 20 years in sealant work

Landlord and commercial work in Chalk Farm
Landlords and agents in Chalk Farm can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Aftercare tips
So the new joints stay in good condition:
- Have a cracking tiled floor checked before tiles break
- Vacuum floor joints regularly to stop grit building up
- Do not fill floor joints with caulk where they move or get wet
- Avoid sloshing water against skirting
Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed until it’s ready.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.
