Floor joint sealing in Finchley
Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out. We work on thresholds, concrete floor joints and wet room & bathroom floors, and the jobs we see most are open joints that fill with dirt and worn sealant at door thresholds.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement, in Finchley as anywhere.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

Landlords, agents and businesses in Finchley
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Tiles that have lifted or broken
- Structural movement or subsidence
- Damaged concrete that needs breaking out and repairing
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Skirting boards
- Concrete floor joints
- Thresholds
- Tiled floors
- Commercial floors
- Wet room & bathroom floors
Floor joint sealing in Finchley: local notes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or 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.
If you let a flat or house near New Southgate station, gaps at skirtings and thresholds are worth sealing between tenancies. As a London address, Finchley can be tricky for parking: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as St Paul's Finchley, joints in its floors, skirtings and thresholds need resealing as they wear.

How it works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a morning or an afternoon for most homes. For a job in Finchley, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- 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.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

Advice
Questions from Finchley
I let a flat near New Southgate station. Can you help?

Is parking an issue for floor joint sealing in Finchley?
Parking in Finchley, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you seal floor joints in bathrooms and kitchens?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone, colour-matched where it shows.
My floor grout keeps cracking in a line. Can you help?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Is caulk good enough for skirting?
Caulk can’t cope with movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Will I be able to paint over the new joint?
Where you plan to paint, we do. Silicone in bathrooms and kitchens cannot be painted.

What else we do in Finchley
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Lift furniture rather than dragging it across joints
- Keep dirt out of the joints
- Ask before painting over a sealed joint
- Keep caulk for dry, still joints only
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up.
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.
Different surfaces, different methods
Commercial floors
Commercial floors take more traffic than most homes. We talk through the traffic and choose a sealant suited to it.
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.
