Floor joint sealing for homes and businesses in Green Street Green
Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out so water and dirt cannot get in. Common call-outs are for concrete floor joints that have broken down and caulk that has cracked where the floor moves, on concrete floor joints, skirting boards and tiled floors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Large cracks that need a surveyor
- Floors that are uneven or need levelling
- Loose, hollow or cracked tiles, which need a tiler
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

What floor joint sealing looks like in Green Street Green
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
Schools such as Green Street Green Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. If you look after a church, hall or community building such as St Mary's Church, joints in its floors, skirtings and thresholds need resealing as they wear.

Why deal with it now?
Not every floor joint takes the same sealant: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work 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.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

How the job changes by surface
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.
Skirting boards
Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking in a colour to suit.
