About our floor joint sealing in Waddon
Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant so water and dirt can’t get in. If you’re dealing with caulk that has cracked where the floor moves and concrete floor joints that have broken down, we can help, on wet room & bathroom floors, skirting boards and concrete floor joints alike.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
All our work is covered by our 12-month guarantee.

FAQs for Waddon
I let a flat near Waddon station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Do you cover Waddon for floor joint sealing?
Yes. We work across London and the South East, and Waddon is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Use a well-wrung mop rather than flooding the floor
- Vacuum floor joints regularly to stop grit building up
- Ask before painting over a sealed joint
- Act on grout cracks that run in a straight line
Don’t paint over silicone. If you plan to paint, we’ll use a paintable product.
Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges and the surface smoother.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.

Joints and finishes in Waddon 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. That is why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
Schools such as Aerodrome Primary Academy are buildings too, and entrance and corridor floor joints take a lot of traffic. Waddon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a church, hall or community building such as Church of St George, joints in its floors, skirtings and thresholds need resealing as they wear.
Waddon is about 1 mile west of Croydon, in Greater London. Waddon gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Our area takes in 764 places across Greater London, from the larger towns to small villages. You can also see our page for London, about 9 miles away.

How the visit works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a morning or an afternoon for most homes in most cases. In Waddon, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at the gap and the floor type and agree the right sealant.
- Old caulk, grout or sealant is removed from the joint.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Before we arrive
- Keep children and pets away from the work area

How the job changes by surface
Concrete floor joints
Old filler, dust and debris are cleaned out of the joint first. Backing goes in where the depth needs controlling.
Commercial floors
Commercial washrooms and kitchens have floor joints that get wet constantly. We reseal them with a sealant suited to wet areas.

What we need to know
Photos by email are helpful but not essential. Try to tell us:
- The problem you’ve noticed
- Whether it’s a home or a business
- Where the property is
- How we’d reach the joints
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or drop us an email.
Why it’s worth doing now in Waddon
Dirt builds up in open joints and makes the floor look worn. Sealed joints are easier to keep clean and finishes the floor. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Waddon, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before work begins.
