Different surfaces, different methods

Commercial floors
Commercial washrooms and kitchens have floor joints that get wet constantly. We reseal them with a sealant suited to wet areas.
About our floor joint sealing in Leyton
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. If you have caulk that has cracked where the floor moves and failed seals where bathroom floors meet baths and panels, we can help, on skirting boards, thresholds and tiled 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 failed shower seals, open skirting joints and gaps at thresholds are typical.
Each job carries a 12-month guarantee.

Your questions about floor joint sealing in Leyton
Is parking an issue for floor joint sealing in Leyton?
Parking in Leyton, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is Leyton in your area for floor joint sealing?
Yes. We work across London and the South East, and Leyton is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Can you reseal concrete floor joints in an industrial unit?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Let us know about the traffic.
How long will you be here?
As a guide, most jobs take a morning or an afternoon for most homes. Bigger jobs take longer.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you seal where the floor meets the bath panel?
Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone so water can’t get into the gap.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on the length of joint, and the area is left clean. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Leyton. It helps if you can point us to a visitor permit or a bay close to the door.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and smooth it.
- Finally, we check the work and talk you through aftercare.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Let us know about parking restrictions

Floor joint sealing in Leyton: local notes
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. The joint at the skirting or threshold has to allow for that.
For site and facilities teams at buildings such as Dawlish Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Leyton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep floor cleaning water to a minimum at the edges
- Walk round the room once a year and look at the edges
- Vacuum floor joints regularly to stop grit building up
- Don’t slide heavy items over sealed joints
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed.
Once concrete joint edges start to break, wheels make it worse. Early resealing helps keep the joint intact.
Why deal with it now?
Not every floor joint takes the same sealant: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Using the wrong one is why many floor joints fail. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Signs you need floor joint sealing in Leyton
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges and the joint gets wider.
Any of these means the joints need attention:
- Gaps at thresholds between rooms
- Open gaps along the bottom of skirting boards
- Perimeter joints in tiled floors filled with grout
- Floor edges that trap water and grime
