Different surfaces, different methods
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, usually low-modulus.
Expansion joint sealing for commercial buildings in Farringdon
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. The enquiries we see most involve torn sealant in brick or block movement joints and hardened, cracked sealant on exposed facades, on cladding panel joints, car park decks and ramps and precast concrete panel joints. A single leaking joint is often how a building in Farringdon first comes to us: we look at the rest while we’re there and tell you what we find.
Around Farringdon, 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, so it pays to act early.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Owners, agents and contractors
We work for building owners and managing agents on everything from one building to a spread of sites around Farringdon. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Keep scrapers and ploughs from dragging across joint sealant
- Avoid parking heavy plant or pallets on joint lines
- Act on the first tear or lifting edge rather than waiting
- Keep product details with the building records for the next reseal
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- How much there is to seal
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- The size and state of each joint
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Any dates the work must fit around
- Anything awkward about access or site hours
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Farringdon: questions and answers
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method.
Will you take on work at estates like Grand Vitesse Industrial Estate, close to Farringdon?
Yes. Our area takes in Farringdon and its surroundings, with estates and business parks such as Grand Vitesse Industrial Estate included. A few photographs and the unit address let us price the work.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
What exactly is a movement joint?
They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading.

Expansion joint sealing around Farringdon: how the place shapes the job
Farringdon has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager.
For a centre such as Brunswick Centre, which lies west of Farringdon, the service yard and car park joints normally need attention first. Across sites such as Southwark Bridge Business Centre, 1.2 miles to the south of Farringdon, floor and movement joints can be sealed in phases so units keep working. Hospital campuses such as St Bartholomew's Hospital (under half a mile south-east of Farringdon) grow in stages, leaving movement joints wherever new blocks meet old.
Farringdon is about 2 miles north of London, in Greater London. Across the EC1V postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places.

Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. 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.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
