What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours, depending on the length of joint. In Norwood Green, 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 checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Advice
Floor joint sealing in Norwood Green
A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors in a colour to suit. Typical jobs include floor edges that trap water and grime and grout used at the floor edge instead of sealant, across concrete floor joints, skirting boards and commercial floors.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Norwood Green as anywhere.
Big or small, you get the same 12-month guarantee in Norwood Green and across Greater London.

Your questions about floor joint sealing in Norwood Green
Can parking be tricky for a visit in Norwood Green?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you work for landlords with property near Southall station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Where do you work from?
We work from Crawley. Our applicators cover Norwood Green, along with the rest of our area.
Can you use decorators’ caulk instead?
Caulk works on still, dry joints, but it cracks where there’s movement or water. We use a flexible sealant for most skirting and floor joints.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months.
Can sealant along the skirting be painted?
If you tell us beforehand, yes. We use a paintable flexible sealant on joints you plan to paint, and silicone elsewhere.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
New homes and floors in Norwood Green
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the 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. The joint at the skirting or threshold has to allow for that.
For site and facilities teams at buildings such as St Mary's Church of England Primary Norwood Green, entrance and corridor floor joints take a lot of traffic. Rented homes near Southall station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

What the job involves on each surface
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and stops debris collecting.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
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. All the old material has to come out first.
Common problems we fix in Norwood Green
Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water, which is why so many skirting joints look broken.
People usually contact us when they notice something like this:
- Rigid edge joints in tiled floors
- Worn sealant at door thresholds
- Open gaps along the bottom of skirting boards
- Open joints that fill with dirt
As a London address, Norwood Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Keeping the joints in good condition
Aftercare is simple:
- Vacuum floor joints regularly to stop grit building up
- Act on grout cracks that run in a straight line
- Use furniture pads near skirting
- Do not fill floor joints with caulk where they move or get wet
Keep heavy furniture from dragging across the joints. Dragging can tear the bead.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen.
Why it’s worth doing now in Norwood Green
Filling a skirting gap with caulk looks fine at first, so the gap reappears. A flexible sealant stretches instead. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Norwood Green, the repair is bigger than a sealant job.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
