Questions from Willesden
Can you do floor joint sealing in Willesden?
Yes, Willesden is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can you help a landlord with a rental near Kensal Rise station?

How long before the joint can take traffic?
We give you a cure time for each joint. Feet are generally fine first, then mopping, then heavy wheels, depending on the product.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Do you have insurance?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
How long will you be here?
A typical job takes a few hours, depending on the length of joint, including preparation and clearing up. We will confirm how long when we quote.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
Floor joint sealing in Willesden
Painted skirting can be sealed with a flexible product that can be painted over. In wet areas we’d normally use silicone because it handles water. Typical jobs include gaps opening between the floor and skirting and cracked caulk along skirting in bathrooms and kitchens, across thresholds, skirting boards and commercial floors.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Willesden and beyond.
Whatever the size of the job, you get the same one-year guarantee in Willesden and across Greater London.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Vacuum floor joints regularly to stop grit building up
- Keep heavy wheels off new concrete joints until cured
- Check the sealant is paintable before decorating
- Don’t fill floor joints with caulk where they move or get wet
Silicone sealant is not made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Small gaps are quick to seal. Left alone, they collect dirt and widen over time.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Bouncy or failing floorboards
- Loose, hollow or cracked tiles, which need a tiler
- Cracked or broken concrete slabs
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What we are called out for in Willesden
Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open.
Signs it’s time to call us include:
- Open joints that fill with dirt
- Rigid edge joints in tiled floors
- Cracked grout where a tiled floor needs a movement joint
- Failed seals where bathroom floors meet baths and panels
If you look after a church, hall or community building such as Church of St Andrew, floor and skirting joints in halls and kitchens wear like any others.
What to look for in a quote
- Is VAT in the price?
- How long to leave it before use
- Whether all the old sealant comes out first
- What insurance they hold
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

New homes and floors in Willesden
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 Kensal Rise station, gaps at skirtings and thresholds are worth sealing between tenancies. Managing a site like St Andrew and St Francis CofE Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

Why act early in Willesden
Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Willesden.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new 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 look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
How to prepare
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
