How we handle floor joint sealing in Soho
Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we close it with a flexible sealant instead. Typical jobs include tiled floors with no room to move and gaps between floors and kitchen plinths, on tiled floors, commercial floors and skirting boards.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
You get a 12-month guarantee, the same in Soho as everywhere else we work.

What happens on the day
Before we leave, we go over the finished joints with you. The visit itself normally takes a morning or an afternoon for most homes, depending on the size of the job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Soho. 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.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

What floor joint sealing looks like in Soho
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.
Community buildings like St Anne's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. If you look after a building such as Soho Parish CofE Primary School, entrance and corridor floor joints take a lot of traffic.
Soho is about 1 mile east of City of Westminster, in Greater London. Our applicators cover floor joint sealing for homes and businesses in Soho and nearby, as part of our work across Greater London. Across Greater London, we cover 764 places, and Soho is one of them.
We work across the W1F, W1T and W1D postcode area for floor joint sealing and the streets around it. If you need floor joint sealing at a property on Duck Lane, Drury Lane and Bridle Lane or a nearby road, our applicators can take on the job.

Near you in Soho
Around Soho, our work takes us to homes and buildings near Bar Soho, St Anne's Churchyard and Harris Westminster Sixth Form and the streets around them. Other local landmarks include LITE Regal International School (0.6 miles west) and London Library (0.5 miles south-west). There’s a railway station in Soho itself: Tottenham Court Road station. A little further out are Kingly Court (under half a mile west) and Montfichet's Tower (1.3 miles east). The countryside around Soho includes St. James's Park Lake and Ludgate Hill.
What happens if it’s left?
Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. Replacing that line with flexible sealant gives it somewhere to go. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Soho, the repair is bigger than a sealant job.
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor.

How the job changes by surface
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.
Wet room and bathroom floors
Mop water gets into any open joint at the edge of a bathroom floor. A neat silicone joint keeps it out.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Do you need floor joint sealing in Soho?
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits, which is why so many skirting joints look broken.
Keep an eye out for any of the following:
- Open gaps along the bottom of skirting boards
- Cracked grout where a tiled floor needs a movement joint
- Chipped and open joints in warehouse floors
- Failed seals where bathroom floors meet baths and panels
Rented homes near Tottenham Court Road station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.
