What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a morning or an afternoon for most homes. For a job in Belgravia, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First we check the joint and the floor and agree which sealant suits it.
- We take out any old caulk, sealant or grout along the line.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

Floor joint sealing in Belgravia
Across Belgravia, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, since that decides which sealant suits. Common call-outs are for skirting that has pulled away from the floor and grout cracking in a straight line across a floor, on skirting boards, tiled floors and concrete floor joints.
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.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What floor joint sealing looks like in Belgravia
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 they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.
For site and facilities teams at buildings such as Holy Trinity CofE Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Belgravia is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Community buildings like St Peter's Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

FAQs for Belgravia
Is Belgravia in your area for floor joint sealing?
Yes. Our work covers London and the South East, and Belgravia is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Do you work for landlords with property near London Victoria station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can you add a movement joint to a tiled floor?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant.
Do you seal warehouse floor joints?
Yes, from warehouses and units to offices and shops. We can plan around your opening times with out-of-hours work where needed.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or email us.
Should I try DIY first?
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.
Are you fully insured?
Yes. Full insurance covers our work.
How the job changes by surface
Tiled floors
Perimeter joints in tiled floors should be sealant, not grout. Grout at the edge is removed and replaced with sealant.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. A sealed joint protects the edges.
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- A tiled floor that needs relaying
- Structural movement or subsidence
- Cracked or broken concrete slabs
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
Where we work in Belgravia
- Concrete floor joints
- Thresholds
- Commercial floors
- Wet room & bathroom floors
- Skirting boards
- Tiled floors
Aftercare tips
So the new joints stay in good condition:
- Have a cracking tiled floor checked before tiles break
- Cone off fresh joints until they’re ready
- Look at floor joints each spring
- Avoid caulk in bathrooms and kitchens
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
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.
Why act early in Belgravia
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Belgravia, the repair is bigger than the sealant job would have been.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
