How we handle floor joint sealing in Eltham
We seal floor joints in homes, offices and commercial buildings across Eltham. Each job starts with looking at the floor and the gap, since that decides which sealant suits. If you’re dealing with open joints around bathroom floor edges and cracked grout where a tiled floor needs a movement joint, we can put it right, on wet room & bathroom floors, commercial floors and thresholds alike.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
Each job carries a 12-month guarantee.

Joints and finishes in Eltham homes
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. That’s why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
Community buildings like Church of Holy Trinity are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Managing a site like St Thomas More Catholic Comprehensive School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Cone off fresh joints until they’re ready
- Check skirting joints after the heating season
- Avoid caulk in bathrooms and kitchens
- Have a cracking tiled floor checked before tiles break
Keep off the joint for the time we give you. Feet are normally fine before mopping or wheeled traffic, and we’ll tell you both.
Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Why it’s worth doing now in Eltham
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. In a flat in Eltham, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
