Floor joint sealing in London Docklands
Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors. We’re often asked to deal with cracked grout where a tiled floor needs a movement joint and failed joint filler in concrete floors, on skirting boards, concrete floor joints and commercial floors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
Big or small, it’s backed by our 12-month guarantee.

Different surfaces, different methods
Thresholds
Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product and tool it flush.
Concrete floor joints
We clean concrete joints out thoroughly before sealing, vacuuming them clean. We fit backing where needed.
Questions from London Docklands
Is parking an issue for floor joint sealing in London Docklands?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near Canary Wharf station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can sealant along the skirting be painted?
On joints you want to paint, yes. Silicone in bathrooms and kitchens can’t be painted, so tell us your plans.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
Do you seal kitchen plinths to the floor?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so we seal them with silicone suited to wet areas.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long does the job take?
A typical job takes a few hours for most rooms, longer for large commercial floors, including the preparation. Your quote will say how long we expect yours to take.
Leave it or put it right?
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 in most rooms. In a flat in London Docklands, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

New homes and floors in London Docklands
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. That’s why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
Managing a site like Tower Hamlets College? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. London Docklands is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For buildings such as St Peter's Church, floor and skirting joints in halls and kitchens wear like any others.

The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on the length of joint.

- We start by checking the floor, the joint and what traffic it takes.
- 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.
- The joint is tooled neatly and the cure time explained.
How to prepare
- Move anything stored near the joints
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children

What else we do in London Docklands
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Use a well-wrung mop rather than flooding the floor
- Look at floor joints each spring
- Don’t fill floor joints with caulk where they move or get wet
- Lift furniture rather than dragging it across joints
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What affects the cost of floor joint sealing
Your quote is based on your job. We look at:
- Which sealant suits the joint
