Northolt Floor Joint Sealing
Problem with your floor joints in Northolt? We cut out the old, prepare the joints and apply the right sealant.

- Skirting caulk that keeps splitting
About our floor joint sealing in Northolt
A threshold joint has to cope with feet, movement and sometimes water. We seal them with a flexible sealant suited to the floor finishes either side. We work on tiled floors, wet room & bathroom floors and skirting boards, and people most often call us about failed joint filler in concrete floors and gaps at thresholds between rooms.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Every job comes with our one-year guarantee.

Why deal with it now?
Dirt builds up in open joints and makes the floor look worn. A neat sealed joint is easier to clean. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Aftercare tips
After the cure time, these simple habits help:
- Vacuum floor joints regularly to stop grit building up
- Ask before painting over a sealed joint
- Don’t fill floor joints with caulk where they move or get wet
- Don’t slide heavy items over sealed joints
Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it until it’s ready.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.

What else we do in Northolt
What the job involves on each surface
Skirting boards
Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking in a colour to suit.
Concrete floor joints
Sawn joints in concrete floors control where it cracks. They’re resealed with a product chosen for what runs over them.
DIY versus a professional finish
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Floor joint sealing in Northolt: local notes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
If you let a flat or house near Northolt Park station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. As a London address, Northolt can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For buildings such as St Richard's Church, floor and skirting joints in halls and kitchens wear like any others.
