Floor joint sealing in St Margarets, done properly
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We’re often asked to deal with skirting caulk that keeps splitting and tiled floors with no room to move, across concrete floor joints, thresholds and wet room & bathroom floors.
Around St Margarets, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

Common questions in St Margarets
Do you cover smaller places like St Margarets?
Yes. St Margarets is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Farningham Road station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What causes gaps between the floor and 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?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
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. Ask us for a quote.

What to tell us for a quote
When you contact us, these details help:
- A few photos by email, if you can
- The problem you’ve noticed
- Whether it has been sealed before
- Whether it’s a home or a business
We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details and send pictures if you have them.
Looking after it afterwards
After the cure time, these simple habits help:
- Sweep along the edges of the floor
- Keep heavy wheels off new concrete joints until cured
- Walk round the room once a year and look at the edges
- Keep floor cleaning water to a minimum at the edges
Check the joints after the first winter. If anything has opened, it’s easy to reseal early on.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.

Leave it or put it right?
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges. Where a wall is exposed, as many are in small places like St Margarets, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

New homes and floors in St Margarets
Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.
Schools such as Greenlands Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Letting a property close to Farningham Road station? Then gaps at skirtings and thresholds are worth sealing between tenancies. Community buildings like Church of St Margaret of Antioch are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
