How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most rooms, longer for large commercial floors. For a job in Old Coulsdon, 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.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Floor joint sealing in Old Coulsdon, done properly
Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. If you’re dealing with open joints that fill with dirt and concrete floor joints that have broken down, we can put it right, on thresholds, wet room & bathroom floors and commercial floors alike.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Every job comes with our 12-month guarantee.

What the job involves on each surface
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. Where water is involved, silicone is the better choice.
Tiled floors
Perimeter joints in tiled floors should be sealant, not grout. Grout at the edge is removed and replaced with sealant.
New homes and floors in Old Coulsdon
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 each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
As a London address, Old Coulsdon can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Keston Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

What else we do in Old Coulsdon
Old Coulsdon questions
I let a flat near Coulsdon South station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Is Old Coulsdon in your area for floor joint sealing?
Yes, Old Coulsdon is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
My floor grout keeps cracking in a line. Can you help?
Often, yes, where it suits the floor. We remove the grout and seal the line with flexible sealant.
Do you seal floor joints in bathrooms and kitchens?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so a flexible silicone is the right choice.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can sealant along the skirting be painted?
If you tell us beforehand, yes. We use a paintable flexible sealant on joints you plan to paint.
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 do not need to watch us work.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What affects the cost of floor joint sealing
We do not publish a price list, because no two jobs are the same. What we look at:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The type of sealant required
- How easy the joints are to reach
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Pictures of the joints, sent by email
- If someone has resealed it before
Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
How to look after the new joints
So the new joints stay in good condition:
- Keep caulk for dry, still joints only
- Walk round the room once a year and look at the edges
- Mark off resealed joints in warehouses
- Keep floor cleaning water to a minimum at the edges
Silicone sealant isn’t made to take paint. If you plan to paint, we’ll use a paintable product.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
Do you need floor joint sealing in Old Coulsdon?
Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away and the joint gets wider.
Common reasons people contact us are:
- Failed joint filler in concrete floors
- Gaps between floors and kitchen plinths
- Grout cracking in a straight line across a floor
- Open joints that fill with dirt
Letting a property close to Coulsdon South station? Then gaps at skirtings and thresholds are worth sealing between tenancies.
