About our floor joint sealing in Stoke Newington
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 with a sealant suited to the movement and traffic. Typical jobs include gaps opening between the floor and skirting and caulk that has cracked where the floor moves, across wet room & bathroom 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.
Every job comes with a 12-month guarantee, wherever you are in Greater London.

What we are called out for in Stoke Newington
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges.
The problems people usually mention when they call include:
- Dirt and water collecting in open floor joints
- Cracked grout where a tiled floor needs a movement joint
- Gaps between floors and kitchen plinths
- Skirting that has pulled away from the floor
Community buildings like Old Church of St Mary are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

- The length of the guarantee
- Whether all the old sealant comes out first
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the job changes by surface
Commercial floors
Commercial floors take more traffic than most homes. We talk through the traffic and choose a sealant suited to it.
Concrete floor joints
We clean concrete joints out thoroughly before sealing first. We fit backing where needed.
Why it’s worth doing now in Stoke Newington
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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 Stoke Newington.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Joints and finishes in Stoke Newington homes
Many of London’s new homes are flats in bigger 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. That is why the skirting and threshold joints need a flexible seal.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Lift furniture rather than dragging it across joints
- Keep caulk for dry, still joints only
- Mark off resealed joints in warehouses
- Vacuum floor joints regularly to stop grit building up
Do not paint over silicone. If you plan to paint, we’ll use a paintable product.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen.
FAQs for Stoke Newington
Can you help a landlord with a rental near Stoke Newington station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is parking an issue for floor joint sealing in Stoke Newington?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Why has a gap opened under my skirting?
Generally it’s movement: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible sealant stays closed as the floor moves.
What does floor joint sealing cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
How long does the job take?
A typical job takes a few hours for most rooms, longer for large commercial floors, including the preparation. Your quote will say how long we expect yours to take.
The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours, depending on the length of joint in most cases. In Stoke Newington, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Advice
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Tiles that have lifted or broken
- Bouncy or failing floorboards
- Damaged concrete that needs breaking out and repairing
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
