Common questions in Sydenham
I let a flat near Sydenham station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Is parking a problem for a job in Sydenham?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can you use decorators’ caulk instead?
Only on dry joints that don’t move. Caulk cracks as the floor moves and the gap reopens. A flexible sealant is the better choice.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before any work starts.
Floor joint sealing in Sydenham, done properly
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. Common call-outs are for open joints around bathroom floor edges and dirt and water collecting in open floor joints, across tiled floors, thresholds and commercial floors.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
All our work is covered by a 12-month guarantee.

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a morning or an afternoon for most homes. In Sydenham, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- 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
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

- Wet room & bathroom floors
- Thresholds
- Tiled floors
- Commercial floors
- Skirting boards
- Concrete floor joints
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not paint over silicone
- Don’t slide heavy items over sealed joints
- Have a cracking tiled floor checked before tiles break
- Vacuum floor joints regularly to stop grit building up
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. Left alone, they collect dirt and widen.
What the job involves on each surface
Concrete floor joints
Old filler, dust and debris are cleaned out of the joint. Backing goes in where the depth needs controlling.
Commercial floors
Commercial washrooms and kitchens have floor joints that get wet constantly. We reseal them with a sealant suited to wet areas.

Why act early in Sydenham
Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. A flexible movement joint is the fix. In a flat in Sydenham, 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, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Joints and finishes in Sydenham homes
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That’s why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
Rented homes near Sydenham station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. Community buildings like Church of St Bartholomew are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Sydenham is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
