Floor joint sealing in Barnehurst, done properly
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant and stops dirt collecting. If you have dirt and water collecting in open floor joints and caulk that has cracked where the floor moves, we can put it right, on commercial floors, skirting boards and tiled floors alike.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Barnehurst and beyond.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Why act early in Barnehurst
Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Barnehurst.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid sloshing water against skirting
- Mark off resealed joints in warehouses
- Don’t slide heavy items over sealed joints
- Get cracks along tile grout lines looked at early
Follow the cure time before walking on or cleaning the joint. Feet are normally fine before mopping or wheeled traffic so we’ll give you each time.
Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further.
How it works
At the end, we look at the finished work together. The work normally takes a morning or an afternoon for most homes, depending on the size of the job. In Barnehurst, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
How to prepare
- Let us know about parking restrictions
- Move anything stored near the joints
- On commercial sites, let us know about site rules

What causes gaps between the floor and skirting?
Generally it’s movement: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible sealant stays closed as the floor moves.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Is caulk good enough for skirting?
Caulk works on still, dry joints, but it splits where the joint moves or gets wet. We use a flexible sealant for most skirting and floor joints.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Floor joint sealing around Barnehurst
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. 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. That’s why the skirting and threshold joints need a flexible seal.
Managing a site like Mayplace Primary School? Then entrance and corridor floor joints take a lot of traffic. As a London address, Barnehurst can be tricky for parking: let us know about parking bays, permits or a driveway.

Honest limits
Some problems need a builder, plumber or other trade rather than us:

The problems people normally mention when they call are:
- Cracked caulk along skirting in bathrooms and kitchens
