Floor Joint Sealing in Dancers Hill
We cover Dancers Hill for sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old sealant removed completely, joints prepared properly.
- Open gaps along the bottom of skirting boards
- Open joints that fill with dirt
- Gaps between floors and kitchen plinths
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Have a cracking tiled floor checked before tiles break
- Look at floor joints each spring
- Vacuum floor joints regularly to stop grit building up
- Do not fill floor joints with caulk where they move or get wet
Silicone sealant isn’t made to take paint. If you plan to paint, we will use a paintable product.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.
How we handle floor joint sealing in Dancers Hill
Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints with a sealant suited to the movement and traffic. Typical jobs include grout used at the floor edge instead of sealant and gaps at thresholds between rooms, on tiled floors, skirting boards and commercial floors.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Dancers Hill and beyond.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Surface by surface
Skirting boards
Gaps between skirting and floor open as timber and floors move. We seal them with a flexible sealant rather than caulk in a colour to suit.
Commercial floors
Commercial floors take more traffic than most homes. The sealant is chosen for the traffic the floor takes.
New homes and floors in Dancers Hill
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.
If you look after a building such as Dame Alice Owen's School, floor and threshold joints in busy corridors wear quickly and are best resealed early. If you let a flat or house near Potters Bar station, a tidy floor and skirting joint helps a rental look ready for the next tenant. As a London address, Dancers Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a morning or an afternoon for most homes. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Dancers Hill. It helps if you can point us to a visitor permit or a bay close to the door.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and tooled.
- Finally, we check the work and talk you through aftercare.
Before we arrive

What happens if it’s left?
Floor joints left open collect dirt that’s hard to clean out and makes the floor look worn. A neat sealed joint is easier to clean. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.

Common questions in Dancers Hill
Is parking a problem for a job in Dancers Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is Dancers Hill in your area for floor joint sealing?
Yes. We work across London and the South East, and Dancers Hill is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can I do 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.
What causes gaps between the floor and skirting?
Timber floors and skirting shrink and swell through the year. A flexible sealant closes the gap without cracking like caulk.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How long does the job take?
As a guide, most jobs take a morning or an afternoon for most homes. Bigger jobs take longer, and we will say how long yours will take.
Can grout be replaced with sealant on a tiled floor?
In many cases, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant. If tiles are loose, that needs fixing first.
Where do you work from?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
