Floor Joint Sealing in Mortlake
Professional floor joint sealing in and around Mortlake, with every bit of old sealant taken out first and a 12-month guarantee.
- Caulk that has cracked where the floor moves
- Threshold joints that have opened or worn
- Failed joint filler in concrete floors
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Don’t fill floor joints with caulk where they move or get wet
- Check the sealant is paintable before decorating
- Mark off resealed joints in warehouses
- Walk round the room once a year and look at the edges
Avoid flooding the floor when you clean. Keeping the edges drier helps the sealant last longer.
A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.
Floor joint sealing for homes and businesses in Mortlake
Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone, which is not made to be painted. If you’re dealing with threshold joints that have opened or worn and tiled floors with no room to move, we can help, on concrete floor joints, thresholds and commercial floors alike.
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 Mortlake as anywhere.
There’s a 12-month guarantee on every job, large or small.

What else we do in Mortlake
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the length of joint. 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 start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Advice
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Floor joint sealing around Mortlake
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That’s why the skirting and threshold joints need a flexible seal. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
Rented homes near Mortlake station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as Thomson House School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. Mortlake is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Mortlake questions
Is Mortlake in your area for floor joint sealing?

How much does floor joint sealing cost in Mortlake?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Why has a gap opened under my skirting?
Floors shrink and settle, especially in the first year or two and through the heating season pulls the skirting and floor apart. Caulk tends to crack; a flexible sealant doesn’t.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you seal floor joints in bathrooms and kitchens?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so we seal them with silicone suited to wet areas.
Why not just use caulk?
Caulk can’t cope with movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
How the job changes by surface
Thresholds
A threshold is where floors and frames meet. A flexible sealant suits both floor finishes.
Wet room and bathroom floors
Bathroom floor edges get wet at every clean. A neat silicone joint keeps it out.
Why deal with it now?
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Mortlake.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
