About our floor joint sealing in Gospel Oak
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we use a flexible sealant that moves with the floor. Typical jobs include caulk that has cracked where the floor moves and threshold joints that have opened or worn, across wet room & bathroom floors, thresholds and tiled floors.
New flats are going up across London, many of them 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.
Our work is backed for twelve months, in Gospel Oak and everywhere else we cover.

FAQs for Gospel Oak
Can you do floor joint sealing in Gospel Oak?
Yes, Gospel Oak is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Is parking an issue for floor joint sealing in Gospel Oak?
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.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
My floor grout keeps cracking in a line. Can you help?
Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. Loose or cracked tiles need a tiler first.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you fully insured?
Yes, we are fully insured.

Related advice
Why act early in Gospel Oak
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Gospel Oak.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why us?

Take a look at what affects the cost and our reviews.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Aftercare tips
To keep the joints looking good and working properly:
- Have a cracking tiled floor checked before tiles break
- Look at floor joints each spring
- Cone off fresh joints until they’re ready
- Keep dirt out of the joints
Silicone sealant isn’t made to take paint. If you plan to paint, we’ll use a paintable product.
Once concrete joint edges start to break, wheels make it worse. Early resealing helps keep the joint intact and the surface smoother.
