Floor joint sealing for homes and businesses in Cold Harbour
Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone because it handles water. If you’re dealing with floor edges that trap water and grime and gaps between floors and kitchen plinths, we can help, on thresholds, commercial floors and wet room & bathroom floors alike.
In a village or hamlet like Cold Harbour, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Leave it or put it right?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, but the movement soon cracks it. A flexible sealant stretches instead. In a small place like Cold Harbour, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Floor joint sealing around Cold Harbour
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 Lawrence are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Rented homes near Charing station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

Cold Harbour: your questions answered
I let a flat near Charing station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Is Cold Harbour within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Do you seal floor joints in bathrooms and kitchens?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so a flexible silicone is the right choice.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Yes. Every job comes with our one-year guarantee.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Related advice
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ask before painting over a sealed joint
- Avoid sloshing water against skirting
- Keep caulk for dry, still joints only
- Look at floor joints each spring
Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal before they spread.
A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.
