The process
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a morning or an afternoon for most homes in most cases. 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.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Clear items away from the joints we are working on

How we handle floor joint sealing in Coldharbour
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. We work on commercial floors, thresholds and concrete floor joints, and the jobs we see most are open joints around bathroom floor edges and gaps opening between the floor and skirting.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Coldharbour as anywhere.
A one-year guarantee comes as standard, so you’re covered after we have gone.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Surface by surface
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
Concrete floor joints
Hard wheels break down the edges of open joints. Sealing them supports the edges.
How we quote for floor joint sealing
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- When we can work, for business premises
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
To help us quote quickly, please include:
- Any access issues, like height or stairs
- The type of property
- The problem you’ve noticed
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
What floor joint sealing looks like in Coldharbour
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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Coldharbour can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Mottingham station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant.

What happens if it’s left?
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. In a flat in Coldharbour, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Why us?
- White, clear, grey or coloured to suit, where the product allows

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid caulk in bathrooms and kitchens
- Mark off resealed joints in warehouses
- Use furniture pads near skirting
- Do not paint over silicone
Follow the cure time before walking on or cleaning the joint. Feet are normally fine before mopping or wheeled traffic, and we will tell you both.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
Common questions in Coldharbour
Is Coldharbour in your area for floor joint sealing?

Can parking be tricky for a visit in Coldharbour?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you have insurance?
Yes. Full insurance covers our work.
When can I walk on the floor?
We give you a cure time for each joint. Feet are normally fine first, then mopping, then heavy wheels in most cases.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.

When to call us in Coldharbour
Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and behind skirting and plinths.
Keep an eye out for these signs:
- Rigid edge joints in tiled floors
- Floor edges that trap water and grime
- Grout cracking in a straight line across a floor
- Skirting that has pulled away from the floor
Community buildings like St Alban are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

- How the surfaces are prepared before sealing
- Whether you can choose the colour
- When the joint can take water or movement
