About our floor joint sealing in South Tottenham
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant in a matching colour. We work on concrete floor joints, commercial floors and thresholds, and common reasons people get in touch are cracked caulk along skirting in bathrooms and kitchens and open gaps along the bottom of skirting boards.
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 South Tottenham and beyond.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Lift furniture rather than dragging it across joints
- Cone off fresh joints until they’re ready
- Keep caulk for dry, still joints only
- Walk round the room once a year and look at the edges
Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant especially in the first few days.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and the edges sound.

What else we do in South Tottenham
How it works
The work is kept neat and contained to the joints we’re treating. The job normally takes a few hours, depending on the length of joint, and we explain the cure time before we leave. For a job in South Tottenham, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We look at the gap and the floor type and agree the right sealant.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

Advice
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Floor joint sealing around South Tottenham
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
South Tottenham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Earlsmead Primary School, entrance and corridor floor joints take a lot of traffic.

Why it’s worth doing now in South Tottenham
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges and keeps the damage down. In a flat in South Tottenham, 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.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Do you use a paintable sealant?
Where you plan to paint, we do. Silicone doesn’t take paint so mention it when you get a quote.

Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

When to call us in South Tottenham
Caulk is the usual filler for skirting. It cracks where there’s movement or water so the gap reappears.
Signs it’s time to call us include:
- Gaps at thresholds between rooms
- Cracked grout where a tiled floor needs a movement joint
- Gaps opening between the floor and skirting
- Rigid edge joints in tiled floors
Rented homes near Seven Sisters station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies.
