How long does floor joint sealing take?

Are you an approved applicator?

Can you add a movement joint to a tiled floor?
Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.
Will I be able to paint over the new joint?
On joints you want to paint, yes. Silicone doesn’t take paint, so tell us your plans.
Floor joint sealing in Mildmay
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We work on wet room & bathroom floors, commercial floors and tiled floors, and the jobs we see most are skirting that has pulled away from the floor and dirt and water collecting in open floor joints.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Wet room and bathroom floors
Wet room floors rely on sound joints at the walls. It’s resealed with a sanitary silicone, and we’ll tell you if the leak seems to come from elsewhere.
Skirting boards
Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing.
Honest limits
To be straight with you, some problems need a different trade:
- Leaks from a failed tanking system
- Loose, hollow or cracked tiles, which need a tiler
- Floors that are uneven or need levelling
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

When to call us in Mildmay
An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap and can reach the subfloor.
Any of these means the joints need attention:
- Open joints that fill with dirt
- Tiled floors with no room to move
- Concrete floor joints that have broken down
- Worn sealant at door thresholds
As a London address, Mildmay can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Floor joint sealing around Mildmay
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they don’t 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 snagging may go through the developer or managing agent.
If you let a flat or house near Dalston Kingsland station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. For site and facilities teams at buildings such as Newington Green Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Cone off fresh joints until they’re ready
- Keep dirt out of the joints
- Act on grout cracks that run in a straight line
- Use furniture pads near skirting
Don’t paint over silicone. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a morning or an afternoon for most homes. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Mildmay. A visitor permit or a nearby bay makes the visit run more smoothly.

Related advice
What happens if it’s left?
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges. In a flat in Mildmay, 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.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
