About our floor joint sealing in Osidge
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant and stops dirt collecting. Common call-outs are for skirting that has pulled away from the floor and grout used at the floor edge instead of sealant, on commercial floors, thresholds and tiled floors.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee in Osidge and across Greater London.

FAQs for Osidge
Can you do floor joint sealing in Osidge?
Yes, Osidge is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Oakleigh Park station?
Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Are you fully insured?
Yes. We are fully insured.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Why not just use caulk?
Only on dry joints that do not move. It splits once the floor shifts, so the gap comes back. A flexible sealant lasts longer there.
How to look after the new joints
So the new joints stay in good condition:
- Act on grout cracks that run in a straight line
- Check the sealant is paintable before decorating
- Look at floor joints each spring
- Keep floor cleaning water to a minimum at the edges
Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead before it has fully cured.
In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.
Signs you need floor joint sealing in Osidge
Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting and they change again in summer.
Most people get in touch when they notice one of these:
- Skirting that has pulled away from the floor
- Open joints that fill with dirt
- Worn sealant at door thresholds
- Gaps between floors and kitchen plinths
Managing a site like Monkfrith Primary School? Then entrance and corridor floor joints take a lot of traffic.
Questions to ask before you book
- How the joint is cleaned and prepared
- The length of the guarantee
- Whether they’re fully insured
- Whether VAT is included

What else we do in Osidge
Joints and finishes in Osidge 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. 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.
For landlords with property near Oakleigh Park station, gaps at skirtings and thresholds are worth sealing between tenancies. As a London address, Osidge can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Different surfaces, different methods
Thresholds
Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, 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
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most rooms, longer for large commercial floors. In Osidge, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
