What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It usually takes a few hours, depending on the length of joint. In a London area like Harringay, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- 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.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
- Mention any tricky access

Advice
Floor joint sealing in Harringay, done properly
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. We work on skirting boards, thresholds and wet room & bathroom floors, and people most often call us about rigid edge joints in tiled floors and gaps between floors and kitchen plinths.
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.
All our work is covered by a one-year guarantee.

Questions from Harringay
Can parking be tricky for a visit in Harringay?
Parking in Harringay, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you cover Harringay for floor joint sealing?
Yes. Our work covers London and the South East, and Harringay is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Why act early in Harringay
Left open, concrete joints break down under traffic. Resealing it early protects the edges before they need a bigger repair. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.

New homes and floors in Harringay
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
If you look after a church, hall or community building such as St Paul's Harringay, joints in its floors, skirtings and thresholds need resealing as they wear. Letting a property close to Harringay Green Lanes station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.
