Floor joint sealing in New Malden
A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors in a colour to suit. We’re often asked to deal with floor edges that trap water and grime and concrete floor joints that have broken down, on wet room & bathroom floors, tiled floors and skirting boards.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement, in New Malden as anywhere.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Common questions in New Malden
Is parking a problem for a job in New Malden?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near New Malden station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you seal kitchen plinths to the floor?
Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone to keep mop water out.
How long before the joint can take traffic?
It depends on the product and the conditions. Before we leave, we tell you when it can be walked on, mopped and driven over so there’s no guesswork.
What does floor joint sealing cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email and let us know what needs doing and where.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Common problems we fix in New Malden
New floors settle once they’re in use. Gaps at the edges appear in the first year or so, and rigid fillers crack.
The most common problems we see are:
- Failed seals where bathroom floors meet baths and panels
- Dirt and water collecting in open floor joints
- Gaps at thresholds between rooms
- Perimeter joints in tiled floors filled with grout
As a London address, New Malden can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What floor joint sealing looks like in New Malden
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same 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 snagging may go through the developer or managing agent.
If you let a flat or house near New Malden station, a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a church, hall or community building such as New Malden Baptist Church, joints in its floors, skirtings and thresholds need resealing as they wear.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a morning or an afternoon for most homes for a typical job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- The sealant goes in, chosen for the floor and coloured to suit it.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Before we arrive
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
