Floor Joint Sealing in Southwark
Our applicators work in Southwark on sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Perimeter joints in tiled floors filled with grout
- Failed seals where bathroom floors meet baths and panels
- Cracked caulk along skirting in bathrooms and kitchens
Leave it or put it right?
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job. In a flat in Southwark, 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.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Southwark clients choose us
- Any old sealant cut out fully, not covered over
- Anti-fungal silicone where joints get wet
- Experience in homes, commercial sites and hotels

Floor joint sealing for homes and businesses in Southwark
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. If you have grout cracking in a straight line across a floor and concrete floor joints that have broken down, we can put it right, on thresholds, commercial floors and wet room & bathroom floors alike.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
All our work comes with a 12-month guarantee.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Vacuum floor joints regularly to stop grit building up
- Don’t fill floor joints with caulk where they move or get wet
- Check skirting joints after the heating season
- Use a well-wrung mop rather than flooding the floor
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up before they spread.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.
Different surfaces, different methods
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.
Tiled floors
When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it.
Signs you need floor joint sealing in Southwark
Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack and joints fail.
Signs it’s time to call us include:
- Chipped and open joints in warehouse floors
- Gaps opening between the floor and skirting
- Caulk that has cracked where the floor moves
- Tiled floors with no room to move
For buildings such as Borough Welsh Congregational Chapel, joints in its floors, skirtings and thresholds need resealing as they wear.

Common questions in Southwark
Is Southwark in your area for floor joint sealing?
Yes, Southwark is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Is parking an issue for floor joint sealing in Southwark?
Parking in Southwark, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Why has a gap opened under my skirting?
Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.
Is caulk good enough for skirting?
Caulk cannot cope with movement or water. Floor edges move through the year, so a flexible sealant suits them better.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Can you add a movement joint to a tiled floor?
Often, yes. A crack along a grout line often means the floor needs room to move. We rake out that line and seal it with flexible sealant.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Large cracks that need a surveyor
- A tiled floor that needs relaying
- Damaged concrete that needs breaking out and repairing
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

The process
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It usually takes a morning or an afternoon for most homes. In Southwark, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
How to prepare
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on

Advice
Joints and finishes in Southwark homes
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 is why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
If you look after a building such as Charles Dickens Primary School, entrance and corridor floor joints take a lot of traffic. As a London address, Southwark can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
