Expansion joint sealing across Smithfield
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Expansion joint sealing for commercial buildings in Smithfield
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing and phasing can keep areas working. Site teams most often ask us about layers of sealant in a movement joint and expansion joints split through the centre of the bead, on brickwork movement joints, podiums and floor movement joints and blockwork control joints. Whoever orders the work in Smithfield, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Around Smithfield, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Move anything stored against the joints
- Share your working hours and any access restrictions
- For older buildings, check the asbestos register before work
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Aftercare for building managers
After handover, these steps help:
- Treat a small split as a warning, not a cosmetic issue
- Include every elevation and deck joint in periodic inspections
- Avoid parking heavy plant or pallets on joint lines
- Brief car park operatives to protect joint lines during winter clearance
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth and we will tell you when each bay or area can reopen. Barriers left in place until then protect the finish.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.
Work for main contractors and building owners
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Traffic, movement and joints around Smithfield
The 3 miles around Smithfield take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards typically have to keep running, so joints are sealed in sections with each area handed back once cured.
If you manage units on an estate such as Grand Vitesse Industrial Estate, 1 mile to the south of Smithfield, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. At places like Southwark Bridge Business Centre, 1.1 miles to the south of Smithfield, joints are sealed a section at a time so operations carry on. Retail centres such as Brunswick Centre, 1 mile to the west of Smithfield, have floors, service yards and car parks with joints under constant traffic.
Smithfield is about 1 mile north of London, in City of London. Smithfield sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 7 places across City of London fall within our area, including Smithfield.
Anyone looking for expansion joint sealing in EC1V, EC1P and EC1R gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on Oat Lane, Shoe Lane and Long Lane or nearby, we can quote for movement joints. You will find Smithfield on or near the A1 and A4. Close to Smithfield, our area also takes in Farringdon (1 mile north), Blackfriars (1 mile south), Holborn (1 mile west), Temple Bar (1 mile south-west) and Clerkenwell (1 mile north).

You’ll also find St Mary-at-Hill (1 mile south-east), Barts Health Archives (less than half a mile south-east) and Postman's Park (less than half a mile south-east). Smithfield has its own railway station: Farringdon station. Well-known places in the area include Finsbury Health Centre (0.5 miles north-west) and Postal Museum (under half a mile south-east). Green spaces nearby include St. James's Park Lake and Ludgate Hill.
How the job changes by surface
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen.
What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Damaged metal nosings or cover plates over a joint
- Joints too narrow for the movement, which need redesigning by the engineer
- Waterproofing layers buried beneath the sealant
If in doubt, phone 01277 525 020 or email us and we will say what we think.
What we seal
- Car park decks and ramps
- Blockwork control joints
- Podiums and floor movement joints
- Brickwork movement joints
- Cladding panel joints
- Precast concrete panel joints

Common questions from Smithfield clients
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do you take on work at healthcare sites like St Bartholomew's Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can a joint be sealed if the edges are broken?
The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first so you are not paying for a bead that won’t hold.
Is Smithfield in your area?
Yes. We cover Smithfield. To discuss a job, call 01277 525 020 or send photos by email.
How much does the work cost?
We don’t publish prices, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
Cost factors for movement joints
Before we quote, we look at:
- The size and state of each joint
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- Site requirements such as inductions and permits
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Specification clauses that apply
- Where the site is, with the postcode
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
