Floor joint sealing for commercial buildings in New Barnet
Concrete floors in warehouses and factories are cut into bays by saw-cut joints and construction joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see so the edges are held up and debris can’t pack in. We work on retail and showroom floors, loading bays and forklift and pallet-truck routes, and the usual reasons a site gets in touch are failing joints at loading bays and dock doors and saw-cut joints left open and packed with grit. A specialist sealant contractor works differently from a general builder: in New Barnet, that means joint design, primers and backing rod as standard.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in New Barnet means thinking about access, loading times and the ULEZ as well as the joints.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email the details over and we will arrange a return visit.

How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. All of Greater London is in the ULEZ, and kerbside space in New Barnet can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We agree the traffic routes and phasing with your site team.
- Any joints with broken edges are flagged before work starts.
- Failed material and debris are removed and the joint cleaned.
- We fill the joints with the agreed product, finished level.
- You get a time for each zone to reopen.
Preparing the site
- Tell us your opening times and when work is allowed
- Agree which areas must stay open
- Arrange parking or a loading space

What happens if it’s left?
Dirt and spillage gather in open joints, out of reach of the floor cleaner. In shops, showrooms and clean production areas that matters for hygiene and appearance. Flush, filled joints leave nothing for cleaners to dig out. Getting scaffold, permits or access booked in New Barnet takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Common problems we fix in New Barnet
A slab keeps shrinking for a long time after it is cast, and saw-cut joints give that shrinkage a planned place to crack. As the panels contract, the joints widen, and a filler placed early can part company with one face.
Look out for the following:
- Loading bay joints breaking down
- Sealant pulled out along a truck route
- Saw-cut joints left open and packed with grit
- Scruffy, dirty joint lines on a shop or showroom floor
For an occupier at a site such as Hadley Manor Trading Estate, 1.3 miles to the north-west of New Barnet, the joints at loading doors and dock levellers normally see the hardest wear.

FAQs: New Barnet
Does your area include sites such as Hadley Manor Trading Estate, near New Barnet?
Yes. Our area takes in New Barnet and its surroundings, with estates and business parks such as Hadley Manor Trading Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is a hospital such as Barnet Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What do you need from us to quote?
A rough joint length, a few photos and a site plan let us give a quick quote. We can visit where that helps so give us a call on 01277 525 020 or email us to set one up.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Broken concrete either side of the joint
- Uneven floors that need grinding or levelling
- Structural cracking in the slab
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think before you book.
