Floor joint sealing in Coombe, done properly
Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed with a sealant suited to the movement and traffic. If you have perimeter joints in tiled floors filled with grout and open joints that fill with dirt, we can put it right, on wet room & bathroom floors, concrete floor joints and commercial floors alike.
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 Coombe as anywhere.

What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for most rooms, longer for large commercial floors. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor and smooth it.
- We check the joints and explain the aftercare.
Before we arrive
- Let us know about parking restrictions
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

FAQs for Coombe
Can you help a landlord with a rental near South Croydon station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you cover Coombe for floor joint sealing?
Yes. We work across London and the South East, and Coombe is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
How long will you be here?
As a guide, most jobs take a morning or an afternoon for most homes. Larger jobs naturally take longer, and we will tell you how long to expect.
How much does floor joint sealing cost in Coombe?

Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Do you have insurance?

My floor grout keeps cracking in a line. Can you help?
In many cases, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. Loose or cracked tiles need a tiler first.
Do you seal warehouse floor joints?
Yes, from warehouses and units to offices and shops. Work can be planned around your hours, and out-of-hours work can be arranged.
Looking after it afterwards
Aftercare is simple:
- Keep heavy wheels off new concrete joints until cured
- Act on grout cracks that run in a straight line
- Keep caulk for dry, still joints only
- Sweep along the edges of the floor
Follow the cure time before walking on or cleaning the joint. Light foot traffic is generally fine sooner than wet cleaning or wheels so we will give you each time.
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.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Subfloor problems that need a flooring contractor
- Damaged concrete that needs breaking out and repairing
- Water getting under the tiles from elsewhere
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Landlords and agents in Coombe can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

What else we do in Coombe
Joints and finishes in Coombe homes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. 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. The joint at the skirting or threshold has to allow for that.
If you let a flat or house near South Croydon station, a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a church, hall or community building such as Church Hall United Reformed Church Of St Paul, floor and skirting joints in halls and kitchens wear like any others. Managing a site like Coombe Wood School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

What the job involves on each surface
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.
Tiled floors
Large or heated tiled floors need room to move. Where needed, a line of grout is replaced with flexible sealant.
