Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. In New Cross, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We look at joint widths, edge condition and the traffic on each route.
- You get a fixed quote with the product and the phasing set out.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- We vacuum each run and prime it if the chosen product requires a primer.
- Filler or sealant goes in to the right depth and is finished flush with the slab.
- The area is handed back once it has cured enough to take traffic.
What we need from you
- Make sure the joints can be reached
- Arrange parking or a loading space
- Tell us what induction or permit system the site runs

Floor joint sealing in New Cross, done properly

Why act early in New Cross
Broken joints shake trucks, stock and operators alike. That means extra wear on wheels and a rougher ride for staff, which nobody budgets for. A filled joint takes most of that out. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why us?
- A fixed quote before work starts
- Failed material removed, not covered up
- Products installed to the manufacturer’s instructions
- Fully insured

Traffic, movement and joints around New Cross
Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager. At least three named trading, business or retail sites lie within about 3 miles of New Cross. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
In a school such as Myatt Garden Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. At a retail site such as New Cross Gate Retail Park, which lies north-west of New Cross, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.
New Cross is about 3 miles south-east of London, in Greater London. Businesses, contractors and managing agents in New Cross can call on us for floor joints, as part of our coverage of Greater London. We work across 764 places in Greater London, large and small.
Work on floor joints is covered throughout SE8, SE14 and SE4, for business premises of every kind. Buildings on Ivy Road, Mona Road and Avon Road are within our area. New Cross sits on or close to the A2209 and A2210, useful when we plan access and materials. We also cover St Johns (1 mile east), Telegraph Hill (1 mile south-west), Deptford (1 mile north-east), Nunhead (1 mile south-west) and Lewisham (1 mile south-east). Bigger towns within reach include London (3 miles north-west), City of Westminster (6 miles north-west), Marylebone (6 miles north-west), Kensington (8 miles west), St Pancras (5 miles north-west) and Shoreditch (4 miles north-west).
Local landmarks in New Cross
Locally, jobs take us to sites close to Wickham Arms, Fordham Park and Addey and Stanhope School and the streets around them. You’ll also find St. Paul's (0.7 miles north-east) and Laban Centre (0.9 miles north-east). New Cross has its own railway station: New Cross station. A little further out are Fan Museum (1.2 miles north-east) and Greenwich Castle (1.5 miles east). Not far away are St. James's Park Lake and Tower Hill.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Treat loading bay joints first if they’re failing
- Allow for topping up joints as a new slab settles
- Hold traffic back until the product has cured
- Sweep debris out of open joints until they can be filled
Once cured, the joints get cleaned along with the slab. If you use strong chemicals or hot-water washing, mention it when we quote so the product suits them.
Treating joints while the arrises are sound keeps the work simple. After the edges go, repairs come into it, with more downtime and more disruption.
When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Wide or random cracking that suggests a structural issue
- Uneven floors that need grinding or levelling
- Damaged or worn floor coatings and screeds
If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Common questions from New Cross clients
Can you work at a site such as New Cross Gate Retail Park, by New Cross?
Yes, sites like New Cross Gate Retail Park are within our area, along with the rest of New Cross. Photos and a short description are enough for a first look.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Is the floor joint work guaranteed?
There is a 12-month guarantee on our workmanship, and we hold public liability insurance.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Which is better for warehouse joints, filler or sealant?
It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises and joints with more movement take a flexible sealant.
Why is there a gap next to the joint filler?
Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. It is typically dealt with by topping up.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Other services in New Cross
What we’re called out for in New Cross
Floor joints collect dust, oil, curing compound and cleaning residue. If the faces aren’t taken back to clean concrete first the new filler can’t stay bonded.
Clients normally get in touch after noticing one or more of the following:
- Broken arrises where pallet trucks cross
- Soft sealant dragged out of trafficked joints
- Cracked and crumbling joint fill
- Untidy open joints in a retail unit
For an estate such as University Hospital Lewisham, 1.4 miles to the south-east of New Cross, the joints in ramps, decks and long building elevations all need attention over time.
