Floor joint sealing in Mill Hill, done properly
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant in a matching colour. Typical jobs include gaps opening between the floor and skirting and open joints around bathroom floor edges, on thresholds, tiled floors and commercial floors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Mill Hill and beyond.
Our work is backed for twelve months, in Mill Hill and everywhere else we cover.

What we’re called out for in Mill Hill

Common reasons people contact us include:
- Failed seals where bathroom floors meet baths and panels
- Grout cracking in a straight line across a floor
- Chipped and open joints in warehouse floors

Mill Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

New homes and floors in Mill Hill
Many of London’s new homes are flats in bigger 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 they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.
If you let a flat or house near Mill Hill Broadway station, gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as St Paul's CofE Primary School NW7 are buildings too, and entrance and corridor floor joints take a lot of traffic.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Use furniture pads near skirting
- Look at floor joints each spring
- Do not fill floor joints with caulk where they move or get wet
- Vacuum floor joints regularly to stop grit building up
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it while it cures.
Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact and the surface smoother.
The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours, depending on the length of joint for a typical job. In Mill Hill, flats, stairs and shared entrances are part of the routine. 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.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

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.

Yes. Concrete floor joints in warehouses and units are part of our work. We will talk through the traffic and choose a sealant suited to it.

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
