About our floor joint sealing in Cranham
Concrete floors in warehouses and units have joints that take heavy wear. We reseal them with a product chosen for the movement and the traffic. We’re often asked to deal with grout cracking in a straight line across a floor and open joints that fill with dirt, across concrete floor joints, tiled floors and skirting boards.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
Every job comes with our one-year guarantee, wherever you are in Greater London.

Cranham: your questions answered
Can you do floor joint sealing in Cranham?
Yes. We work across London and the South East, and Cranham is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Is parking a problem for a job in Cranham?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Why has a gap opened under my skirting?
It’s normally the floor moving: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible bead keeps up with the movement.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you seal kitchen plinths to the floor?
Yes. The old joint comes out and a flexible silicone replaces it, colour-matched where it shows.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Why act early in Cranham
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. 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. Dealing with it early is far simpler for homes in Cranham.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why us?
- ARBOMaster approved applicator
- Homes, businesses and hotels
- Quality sealants from Arbo and Everbuild
- A sealant colour to suit the surroundings

When it is not the sealant
A few problems are outside what sealant work can do:
- Bouncy or failing floorboards
- Failed waterproofing under a wet room floor
- Tiles that have lifted or broken
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Surface by surface
Commercial floors
Floor joint work in businesses can be planned around your hours. Out-of-hours working can be arranged.
Wet room and bathroom floors
Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone to keep water out of the edges.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Check skirting joints after the heating season
- Have a cracking tiled floor checked before tiles break
- Avoid caulk in bathrooms and kitchens
- Vacuum floor joints regularly to stop grit building up
Do not paint over silicone. If you plan to paint, we’ll use a paintable product.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Floor joint sealing in Cranham: local notes
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial 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 snagging may go through the developer or managing agent.
If you let a flat or house near Upminster station, gaps at skirtings and thresholds are worth sealing between tenancies. Community buildings like St Luke's Cranham are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like Hall Mead School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.
