Floor joint sealing for homes and businesses in Ashburton
Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints with a sealant suited to the movement and traffic. We work on wet room & bathroom floors, concrete floor joints and thresholds, and common reasons people get in touch are gaps opening between the floor and skirting and chipped and open joints in warehouse floors.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Water getting under the tiles from elsewhere
- Subfloor problems that need a flooring contractor
- Structural movement or subsidence
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Why act early in Ashburton
Leaving skirting gaps until the next decorating job lets dirt and draughts in. It’s a quick job to seal them now in most rooms. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Ashburton.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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.
Your questions about floor joint sealing in Ashburton
Is Ashburton in your area for floor joint sealing?
Yes. Our work covers London and the South East, and Ashburton is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
I let a flat near Norwood Junction station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How soon can the floor be mopped?
We’ll tell you before we leave. That depends on the product, and light foot traffic is normally fine before wet cleaning or wheels.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Aftercare tips
Looking after new joints is easy:
- Avoid caulk in bathrooms and kitchens
- Do not paint over silicone
- Mark off resealed joints in warehouses
- Look at floor joints each spring
Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.
Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further.
Surface by surface
Commercial floors
Floor joint work in businesses can be planned around your hours. We can arrange out-of-hours work.
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.
What floor joint sealing looks like in Ashburton
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
For site and facilities teams at buildings such as St Thomas Becket Catholic Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. As a London address, Ashburton can be tricky for parking: let us know about parking bays, permits or a driveway.

People normally contact us when they notice one of these:
- Concrete floor joints that have broken down
- Open gaps along the bottom of skirting boards
- Gaps at thresholds between rooms
- Cracked grout where a tiled floor needs a movement joint

How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours for most rooms, longer for large commercial floors. In a London area like Ashburton, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- The chosen sealant goes in, coloured to suit the floor.
- The joint is tooled neatly and the cure time explained.
How to prepare
- Clear the area around the work
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
