Floor joint sealing around Clapham Junction
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
Clapham Junction is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Christ Church CofE Primary School, entrance and corridor floor joints take a lot of traffic.

Floor joint sealing in Clapham Junction, done properly
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. We work on wet room & bathroom floors, thresholds and commercial floors, and people most often call us about skirting that has pulled away from the floor and gaps between floors and kitchen plinths.
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.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Clapham Junction questions
Can you do floor joint sealing in Clapham Junction?
Yes, Clapham Junction is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Is parking an issue for floor joint sealing in Clapham Junction?
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.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Why does the gap under my skirting keep coming back?
It’s normally the floor moving: heating drying the timber, or a filler that’s too rigid. A flexible sealant stays closed as the floor moves.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What we’re called out for in Clapham Junction
Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting, then close again in damper months.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening between the floor and skirting
- Floor edges that trap water and grime
- Threshold joints that have opened or worn
- Rigid edge joints in tiled floors
For landlords with property near Clapham Junction station, a tidy floor and skirting joint helps a rental look ready for the next tenant.
Questions to ask before you book
- How long the guarantee is
- How the colour is chosen
- Is VAT in the price?
- Are they insured?

DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What the job involves on each surface
Tiled floors
Tiled floors need movement joints at edges and across large areas. Where needed, a line of grout is replaced with flexible sealant coloured to suit.
Commercial floors
Commercial floors take more traffic than most homes. The sealant is chosen for the traffic the floor takes.
How it works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes a few hours, depending on the length of joint. In a London area like Clapham Junction, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we check the joint and the floor and agree which sealant suits it.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Advice
Leave it or put it right?
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Clapham Junction, the repair is bigger than the sealant job would have been.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
