About our floor joint sealing in Thornton Heath
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. If you’re dealing with tiled floors with no room to move and caulk that has cracked where the floor moves, we can help, whatever the surface.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Tiled floors
Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines in a matching colour.
Thresholds
Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.
New homes and floors in Thornton Heath
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. The joint at the skirting or threshold has to allow for that. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
Thornton Heath is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as Church of St Stephen, floor and skirting joints in halls and kitchens wear like any others. For landlords with property near Thornton Heath station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Do not fill floor joints with caulk where they move or get wet
- Cone off fresh joints until they’re ready
- Use furniture pads near skirting
- Avoid sloshing water against skirting
Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant.
Small gaps are quick to seal. Ignored, they fill with dirt and open further and are harder to clean out.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a morning or an afternoon for most homes. 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.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
