How we handle floor joint sealing in Bloomsbury
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk normally cracks where there’s movement, so we use a flexible sealant that moves with the floor. We work on commercial floors, tiled floors and concrete floor joints, and the jobs we see most are failed joint filler in concrete floors and dirt and water collecting in open floor joints.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement.
All our work is covered by our one-year guarantee.

How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a morning or an afternoon for most homes. In Bloomsbury, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Floor joint sealing around Bloomsbury
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That’s 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.
Bloomsbury is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near London Euston station, gaps at skirtings and thresholds are worth sealing between tenancies.

Common questions in Bloomsbury
Can parking be tricky for a visit in Bloomsbury?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near London Euston station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Bloomsbury, along with the rest of our area.
Is it worth trying it myself?
Sometimes. 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 I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What causes gaps between the floor and skirting?
Floors shrink and settle, especially in the first year or two and through the heating season opens the gap. Rigid fillers split, so we use a flexible sealant.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What happens if it’s left?
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. It’s a quick job to seal them now for most homes. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Bloomsbury, the repair is bigger than the sealant job would have been.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep heavy wheels off new concrete joints until cured
- Don’t fill floor joints with caulk where they move or get wet
- Keep dirt out of the joints
- Lift furniture rather than dragging it across joints
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
Small gaps are quick to seal. Ignored, they fill with dirt and open further and are harder to clean out.
Do you need floor joint sealing in Bloomsbury?
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. You will see a crack running along the grout, showing where a movement joint was needed.
Common reasons people contact us include:
- Skirting that has pulled away from the floor
- Grout cracking in a straight line across a floor
- Dirt and water collecting in open floor joints
- Perimeter joints in tiled floors filled with grout
If you look after a building such as UCL School of Slavonic and East European Studies, floor and threshold joints in busy corridors wear quickly and are best resealed early.
