Floor joint sealing in Golders Green
Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is normally the better choice because it handles water. Common call-outs are for failed seals where bathroom floors meet baths and panels and gaps opening between the floor and skirting, across concrete floor joints, skirting boards and wet room & bathroom floors.
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 Golders Green as anywhere.
Our work is backed for twelve months.

Floor joint sealing around Golders Green
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
Rented homes near Cricklewood station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. For site and facilities teams at buildings such as Rimon Jewish Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. As a London address, Golders Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Golders Green questions
I let a flat near Cricklewood station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you cover Golders Green for floor joint sealing?
Yes, Golders Green is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Why not just use caulk?
Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do you seal kitchen plinths to the floor?
Yes. The old joint comes out and a flexible silicone replaces it in a colour to suit.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
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. Tell us what runs over the floor.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Landlords and letting agents in Golders Green can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Don’t fill floor joints with caulk where they move or get wet
- Avoid sloshing water against skirting
- Check skirting joints after the heating season
- Cone off fresh joints until they’re ready
Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed while it cures.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.
Surface by surface
Concrete floor joints
Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.
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.

- The joint is cleaned, vacuumed and backed where depth needs controlling.
