Swiss Cottage Floor Joint Sealing
Sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints for householders, landlords and businesses in Swiss Cottage. Fully insured, ARBOMaster approved and guaranteed for a year.
- Threshold joints that have opened or worn
- Cracked grout where a tiled floor needs a movement joint
- Failed seals where bathroom floors meet baths and panels
Common problems we fix in Swiss Cottage
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges until the joint widens.
Any of these means the joints need attention:
- Dirt and water collecting in open floor joints
- Threshold joints that have opened or worn
- Gaps between floors and kitchen plinths
- Skirting that has pulled away from the floor
For site and facilities teams at buildings such as The UCL Academy, entrance and corridor floor joints take a lot of traffic.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- When the joint can take water or movement
- Whether all the old sealant comes out first
Floor joint sealing in Swiss Cottage
Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed. Typical jobs include floor edges that trap water and grime and caulk that has cracked where the floor moves, on commercial floors, concrete floor joints and thresholds.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
We stand behind the work with a 12-month guarantee.

How we quote for floor joint sealing
We do not publish a price list, because no two jobs are the same. What we look at:
- The amount of work
- How easy the joints are to reach
- The number of rooms or windows
- Mould in or behind the old joints
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- How we’d reach the joints
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Questions from Swiss Cottage
Is parking an issue for floor joint sealing in Swiss Cottage?
Parking in Swiss Cottage, 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.
Do you cover Swiss Cottage for floor joint sealing?
Yes. We work across London and the South East, and Swiss Cottage is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can you add a movement joint to a tiled floor?
Often, yes. We replace the grout along a suitable line with flexible sealant. Loose or cracked tiles need a tiler first.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Can you reseal concrete floor joints in an industrial unit?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Let us know about the traffic when you ask for a quote.
When can I walk on the floor?
You’ll get the times before we go. That depends on the product, and light foot traffic is usually fine before wet cleaning or wheels.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Why not just use caulk?
Caulk cannot cope with movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Structural movement or subsidence
- A tiled floor that needs relaying
- Leaks from a failed tanking system
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

Joints and finishes in Swiss Cottage homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. 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.
As a London address, Swiss Cottage can be tricky for parking: let us know about parking bays, permits or a driveway. Community buildings like Church of All Souls are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

How to look after the new joints
Aftercare is simple:
- Lift furniture rather than dragging it across joints
- Sweep along the edges of the floor
- Use a well-wrung mop rather than flooding the floor
- Cone off fresh joints until they’re ready
Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Why deal with it now?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant moves with the floor, so the joint stays closed. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Swiss Cottage.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
