About our floor joint sealing in South Hampstead
Concrete floors in warehouses and factories are cut into bays with saw cuts and day joints, and each joint line is a weak edge that wheels run over all day. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. We work on construction joints, forklift and pallet-truck routes and joints along racking aisles, and the usual reasons a site gets in touch are dock area joints that have failed first and saw-cut joints left open and packed with grit. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in South Hampstead it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In South Hampstead, as everywhere in London, access, loading and the ULEZ all come into the plan.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- A failing floor coating, which is a flooring contractor’s job
- Level or flatness problems across the floor
- Structural cracking in the slab
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
What we seal
- Saw-cut induced joints
- Construction joints
- Retail and showroom floors
- Joints along racking aisles
- Forklift and pallet-truck routes
- Loading bays
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Access and working height
- Whether the work must be split into stages
- The site’s rules and procedures
- Quantities, in metres or numbers
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- Clear photographs of the problem areas
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- Any dates the work must fit around
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. In South Hampstead, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First, the zones and order of work are agreed with you.
- We point out joints whose edges need repairing first.
- Failed material and debris are removed and the joint cleaned.
- The chosen filler or sealant goes in flush with the slab.
- You get a time for each zone to reopen.
Getting the site ready
- Let us know about inductions and permits
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand

Advice
Maintenance after handover
After handover, these steps help:
- Sweep debris out of open joints until they can be filled
- Keep photographs of joints that look like they’re failing
- Expect fillers on young slabs to need a top-up
- Make joint checks part of your floor inspections
Keep traffic off fresh joints until the time we give you, and it’s worth enforcing. In a busy building, barriers keep early traffic away.
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.

Questions about South Hampstead
Do you take on work at healthcare sites like Hospital of St John and St Elizabeth?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work at a site such as Regis Road Business Park, by South Hampstead?
Yes, sites like Regis Road Business Park are within our area, along with the rest of South Hampstead. Send details of the unit and the work through our quote form for a quick quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Can you fill joints where the arrises have spalled?
Filling against broken edges doesn’t last. If the arrises have spalled, we’ll say they need repair before filling and set out how that affects the job.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.

Hospital campuses such as Hospital of St John and St Elizabeth (0.6 miles south of South Hampstead) grow in stages, leaving movement joints wherever new blocks meet old.
