Floor joint sealing for homes and businesses in Crofton
We seal floor joints in homes, offices and commercial buildings across Crofton. We start by checking the floor type and the joint, because the right sealant depends on both. If you have gaps at thresholds between rooms and open joints around bathroom floor edges, we can put it right.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Crofton and beyond.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

What happens on the day
Once we’re on site, 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, depending on the length of joint. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Crofton. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- 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
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Common problems we fix in Crofton
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges.
Look out for any of the following:
- Open joints that fill with dirt
- Perimeter joints in tiled floors filled with grout
- Cracked caulk along skirting in bathrooms and kitchens
- Failed seals where bathroom floors meet baths and panels
Crofton is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
What to look for in a quote

- Are they insured?

Leave it or put it right?
Left open, concrete joints break down under traffic. A sealed joint supports the edges and keeps the damage down. In a flat in Crofton, 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.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

How the job changes by surface
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.
Wet room and bathroom floors
Wet room floors rely on sound joints at the walls. We reseal it with a flexible silicone suited to wet areas, and we will tell you if the leak seems to come from elsewhere.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Get cracks along tile grout lines looked at early
- Look at floor joints each spring
- Mark off resealed joints in warehouses
- Don’t slide heavy items over sealed joints
Silicone sealant isn’t made to take paint. If you plan to paint, we will 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.
Joints and finishes in Crofton homes
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
For landlords with property near Orpington station, gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as Crofton Infant School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
