North Cheam Floor Joint Sealing
Sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints for homes and businesses in North Cheam and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Grout cracking in a straight line across a floor
- Open joints around bathroom floor edges
- Worn sealant at door thresholds
Can I do it myself?
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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Floor joint sealing in North Cheam, done properly
Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is generally the better choice. We are often asked to deal with cracked caulk along skirting in bathrooms and kitchens and grout cracking in a straight line across a floor, across thresholds, skirting boards and tiled floors.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
There’s a 12-month guarantee on every job, large or small.

How to look after the new joints
To keep the joints looking good and working properly:
- Don’t fill floor joints with caulk where they move or get wet
- Cone off fresh joints until they’re ready
- Keep dirt out of the joints
- Walk round the room once a year and look at the edges
Keep off the joint for the time we give you. Light foot traffic is usually fine sooner than wet cleaning or wheels.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.
For landlords and businesses
Landlords and agents in North Cheam can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on the length of joint. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and tooled.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before

Why act early in North Cheam
Dirt builds up in open joints, and they look untidy. A neat sealed joint is easier to clean and finishes the floor. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in North Cheam, the repair is bigger than the sealant job would have been.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Do you work for landlords with property near West Sutton station?

Do you guarantee your work?

What causes gaps between the floor and skirting?
Usually it’s movement: heating drying the timber, or a filler that is too rigid. A flexible bead keeps up with the movement.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Can you add a movement joint to a tiled floor?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant.
Are you insured?
Yes. We’re fully insured.
What affects the quote in North Cheam
There’s no set price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- Working hours on commercial sites
- The product the joint needs
- How much there is to do
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The type of property
- What’s wrong with the joints now
- The rough size of the job
- How we’d reach the joints

Honest limits
In fairness, some problems need a different trade:
- Large cracks that need a surveyor
- Concrete repairs beyond the joint
- Loose, hollow or cracked tiles, which need a tiler
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Floor joint sealing around North Cheam
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
For buildings such as St Oswald Church, joints in its floors, skirtings and thresholds need resealing as they wear. If you let a flat or house near West Sutton station, a tidy floor and skirting joint helps a rental look ready for the next tenant. North Cheam is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
