About our floor joint sealing in Clerkenwell
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant. We’re often asked to deal with floor edges that trap water and grime and cracked grout where a tiled floor needs a movement joint, across concrete floor joints, commercial floors and thresholds.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement, in Clerkenwell as anywhere.
All our work is covered by a 12-month guarantee, wherever you are in Greater London.

Floor joint sealing around Clerkenwell
Much of London’s new housing is flats in larger 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.
For buildings such as St James's Church, joints in its floors, skirtings and thresholds need resealing as they wear. Schools such as St Peter and St Paul RC Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, wherever you are.

What we’re called out for in Clerkenwell
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.
Most people get in touch when they notice something like this:
- Concrete floor joints that have broken down
- Gaps at thresholds between rooms
- Cracked caulk along skirting in bathrooms and kitchens
- Floor edges that trap water and grime
As a London address, Clerkenwell can be tricky for parking: let us know about parking bays, permits or a driveway.

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes a morning or an afternoon for most homes. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Clerkenwell. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at the gap and the floor type and agree the right sealant.
- We take out any old caulk, sealant or grout along the line.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- 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.
How to prepare
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before

Related advice
Why act early in Clerkenwell
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
Why book with us
- We agree the colour with you first
- ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet
- More than 20 years in sealant work

Surface by surface
Concrete floor joints
Sawn joints in concrete floors control where it cracks. They’re resealed with a product chosen for what runs over them.
Thresholds
Two different floors meeting at a threshold move differently. We bridge them with a flexible bead.
What sealant work can’t fix
It helps to know what we cannot do too:
- Structural movement or subsidence
- Floors that are uneven or need levelling
- Loose, hollow or cracked tiles, which need a tiler
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

DIY versus a professional finish
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.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Landlords, agents and businesses in Clerkenwell
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
