Questions from St John's Wood
Can you do floor joint sealing in St John's Wood?
Yes. We work across London and the South East, and St John's Wood is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can parking be tricky for a visit in St John's Wood?
Parking in St John's Wood, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What should I tell you?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Can you reseal concrete floor joints in an industrial unit?
Yes. We reseal concrete floor joints in commercial and industrial units. The product is chosen for the traffic the floor takes.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Do you seal kitchen plinths to the floor?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so a flexible silicone is the right choice.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
About our floor joint sealing in St John's Wood
Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on thresholds, commercial floors and skirting boards, and people most often call us about gaps at thresholds between rooms and caulk that has cracked where the floor moves.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in St John's Wood and beyond.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Joints and finishes in St John's Wood homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or 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. That’s why the skirting and threshold joints need a flexible seal.
Managing a site like George Eliot Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. If you look after a church, hall or community building such as Church of All Souls, joints in its floors, skirtings and thresholds need resealing as they wear.

When to call us in St John's Wood
Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open.
These are the problems we are asked about most:
- Gaps opening between the floor and skirting
- Open joints around bathroom floor edges
- Open joints that fill with dirt
- Concrete floor joints that have broken down
St John's Wood is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a morning or an afternoon for most homes. In a London area like St John's Wood, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep floor cleaning water to a minimum at the edges
- Don’t slide heavy items over sealed joints
- Avoid caulk in bathrooms and kitchens
- Cone off fresh joints until they’re ready
Silicone sealant is not made to take paint. If you plan to paint, we will use a paintable product.
Small gaps are quick to seal. Ignored, they fill with dirt and open further.
