About our floor joint sealing in Middle Park
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk usually cracks where there’s movement, so we use a flexible sealant that moves with the floor. If you have failed seals where bathroom floors meet baths and panels and grout used at the floor edge instead of sealant, we can help, whatever the surface.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the 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 with the work, just as it does everywhere we cover.

Why it’s worth doing now in Middle Park
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Middle Park, the repair is bigger than a sealant job.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

Advice
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What the job involves on each surface
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.
Commercial floors
Commercial washrooms and kitchens have floor joints that get wet constantly. They’re resealed with a flexible, water-resistant sealant.
FAQs for Middle Park
Is parking a problem for a job in Middle Park?
Parking in Middle Park, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Mottingham station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
What causes gaps between the floor and skirting?
Movement from drying timber and settling floors opens the gap. Rigid fillers split, so we use a flexible sealant.
How much does floor joint sealing cost in Middle Park?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Looking after it afterwards
After the cure time, these simple habits help:
- Act on grout cracks that run in a straight line
- Check the sealant is paintable before decorating
- Don’t slide heavy items over sealed joints
- Walk round the room once a year and look at the edges
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it until it’s ready.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner.
New homes and floors in Middle Park
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
Middle Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For buildings such as Church of St Saviour, joints in its floors, skirtings and thresholds need resealing as they wear.

What we’re called out for in Middle Park
Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water.
Common reasons people contact us are:
- Open joints that fill with dirt
- Perimeter joints in tiled floors filled with grout
- Tiled floors with no room to move
- Gaps between floors and kitchen plinths
Letting a property close to Mottingham station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.
