- Grout cracking in a straight line across a floor
- Chipped and open joints in warehouse floors
- Gaps at thresholds between rooms
- Rigid edge joints in tiled floors
If you let a flat or house near Crayford station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

Floor joint sealing in Crayford, done properly
A threshold joint has to cope with feet, movement and sometimes water. We seal them with a flexible sealant suited to the floor finishes either side in a colour to suit. If you have open joints that fill with dirt and worn sealant at door thresholds, we can help.
If you’ve bought a new home in or near Crayford, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.

FAQs for Crayford
Do you work for landlords with property near Crayford station?
Yes. We work for letting agents and landlords as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Crayford within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for most rooms, longer for large commercial floors. We’ll give you a better idea when we quote.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Joints and finishes in Crayford homes
Floors around Kent 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.
Community buildings like Church of St Paulinus are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like Wentworth Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and tooled.
- We check the joints and explain the aftercare.

Related advice
Why it’s worth doing now in Crayford
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. In an older home around Crayford, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Look at floor joints each spring
- Act on grout cracks that run in a straight line
- Don’t paint over silicone
- Avoid sloshing water against skirting
Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.
Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact and the floor safer.
