How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for most rooms, longer for large commercial floors in most cases. For a job in St George's Fields, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

Floor joint sealing in St George's Fields, done properly
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed. We work on wet room & bathroom floors, concrete floor joints and thresholds, and people most often call us about cracked caulk along skirting in bathrooms and kitchens and cracked grout where a tiled floor needs a movement joint.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in St George's Fields and beyond.
Your job is guaranteed for a year, as with all our work.

What floor joint sealing looks like in St George's Fields
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 is why the skirting and threshold joints need a flexible seal. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
Letting a property close to Elephant & Castle station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty. Schools such as St George's Cathedral Catholic Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
When something else is needed
In fairness, some problems need a different trade:
- Structural movement or subsidence
- Concrete repairs beyond the joint
- Floors that are uneven or need levelling
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Where we work in St George's Fields

Leave it or put it right?
Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. A flexible movement joint is the fix. 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.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- You choose the colour before work begins
- One-year guarantee on every job
- We leave the area clean and tidy
- White, clear, grey or coloured to suit, where the product allows

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Do you need floor joint sealing in St George's Fields?
Caulk is the usual filler for skirting. It cracks where there’s movement or water so the gap reappears.
People normally contact us after spotting one of these:
- Cracked grout where a tiled floor needs a movement joint
- Failed seals where bathroom floors meet baths and panels
- Skirting caulk that keeps splitting
- Open joints that fill with dirt
Community buildings like Former Church of St Jude are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
