Floor joint sealing in Mottingham
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk usually cracks where there’s movement, so we close it with a flexible sealant instead. Typical jobs include cracked grout where a tiled floor needs a movement joint and concrete floor joints that have broken down, on tiled floors, skirting boards and concrete floor joints.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on the length of joint for a typical job. 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.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- The chosen sealant goes in, coloured to suit the floor.
- The joint is tooled neatly and the cure time explained.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Joints and finishes in Mottingham homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Floors around Greater London 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.
If you look after a church, hall or community building such as Jubilee International Church, joints in its floors, skirtings and thresholds need resealing as they wear. Rented homes near Grove Park station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant. As a London address, Mottingham can be tricky for parking: let us know about parking bays, permits or a driveway.

When something else is needed
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Structural movement or subsidence
- Bouncy or failing floorboards
- Tiles that have lifted or broken
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Tiled floors
- Thresholds
- Concrete floor joints
- Skirting boards
- Commercial floors
- Wet room & bathroom floors
How the job changes by surface
Skirting boards
Gaps between skirting and floor open as timber and floors move. We seal them with a flexible sealant rather than caulk painted or coloured to match.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. A sealed joint protects the edges and stops debris collecting.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Vacuum floor joints regularly to stop grit building up
- Mark off resealed joints in warehouses
- Ask before painting over a sealed joint
- Look at floor joints each spring
Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant before it has fully cured.
Small gaps are quick to seal. Left alone, they collect dirt and widen and are harder to clean out.
Why act early in Mottingham
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. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

Your questions about floor joint sealing in Mottingham
Is Mottingham in your area for floor joint sealing?
Yes, Mottingham is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Is parking a problem for a job in Mottingham?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Why not just use caulk?
Caulk cannot cope with movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
