Floor joint sealing for homes and businesses in Pinner Green
The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk generally cracks where there’s movement, so we use a flexible sealant that moves with the floor. If you have gaps between floors and kitchen plinths and rigid edge joints in tiled floors, we can help.
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.
A one-year guarantee comes as standard, so you’re covered after we have gone.

The process
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for most rooms, longer for large commercial floors for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Pinner Green. 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.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and tooled.
- We check the joints and explain the aftercare.
How to prepare
- Tell us about any water getting in
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit

Joints and finishes in Pinner Green homes
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. That’s why the skirting and threshold joints need a flexible seal. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
Rented homes near Hatch End station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as Christian Science Church, joints in its floors, skirtings and thresholds need resealing as they wear.

- Caulk that has cracked where the floor moves
- Skirting that has pulled away from the floor

Questions to ask before booking
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- How hidden problems are handled
- Whether they’re fully insured
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What the job involves on each surface
Concrete floor joints
Old filler, dust and debris are cleaned out of the joint first. Backing goes in where the depth needs controlling.
Wet room and bathroom floors
Mop water gets into any open joint at the edge of a bathroom floor. A neat silicone joint keeps it out.
Leave it or put it right?
Dirt builds up in open joints. A neat sealed joint is easier to clean and finishes the floor. In a flat in Pinner Green, 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.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Pinner Green: your questions answered
Is parking an issue for floor joint sealing in Pinner Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Hatch End station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can sealant along the skirting be painted?
It depends on the sealant, so let us know first. We use a paintable flexible sealant on joints you plan to paint.
How long does the job take?
As a guide, most jobs take a morning or an afternoon for most homes. Bigger jobs take longer, and we’ll say how long yours will take.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Where do you work from?
Mr Mastic is based in Crawley. We cover Pinner Green and the rest of Greater London.
