Floor joint sealing in Thamesmead, done properly
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed using a product that suits the floor. Common call-outs are for worn sealant at door thresholds and floor edges that trap water and grime, across skirting boards, wet room & bathroom floors and commercial floors.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Common questions in Thamesmead
Can parking be tricky for a visit in Thamesmead?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Abbey Wood station?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you seal kitchen plinths to the floor?
Yes. The old joint comes out and a flexible silicone replaces it.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How long will you be here?
That depends on the amount of work, but as a guide it takes a morning or an afternoon for most homes. We will tell you when we quote.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Joints and finishes in Thamesmead homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. 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.
Thamesmead is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Community buildings like St Paul are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. If you let a flat or house near Abbey Wood station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
Thamesmead is about 2 miles north-east of Plumstead, in Greater London. Across the SE28 area, our applicators can take on floor joint sealing. Our Greater London coverage runs to 764 places, and Thamesmead is one of them. London is on our list too, around 10 miles away.

What’s near Thamesmead
In Thamesmead, that means homes and buildings near Harris Garrard Academy and Abbey Wood Park. For rail, the closest station is Abbey Wood station, about 1 mile south of the centre. A little further out are Greenwich Borough Museum (1.7 miles south-west) and Gallions Reach Shopping Park (2 miles west). Not far away are Crossness Nature Reserve.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Do not fill floor joints with caulk where they move or get wet
- Check skirting joints after the heating season
- Don’t paint over silicone
- Don’t slide heavy items over sealed joints
Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed until it’s ready.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.
What happens on the day
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning or an afternoon for most homes. In a London area like Thamesmead, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- The joint is tooled neatly and the cure time explained.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

What sealant work cannot fix
Before booking, it’s worth knowing the limits too:
- Failed waterproofing under a wet room floor
- Concrete repairs beyond the joint
- Subfloor problems that need a flooring contractor
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Joints and surfaces we work on
- Tiled floors
- Commercial floors
- Concrete floor joints
- Thresholds
- Skirting boards
- Wet room & bathroom floors
How the job changes by surface
Thresholds
Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.
Skirting boards
Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing.
Why act early in Thamesmead
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. It’s a quick job to seal them now for most homes. In a flat in Thamesmead, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
Why choose Mr Mastic in Thamesmead
- A sealant colour to suit the surroundings

- Arbo and Everbuild products

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
