FAQs: Chinatown
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as Grand Vitesse Industrial Estate, near Chinatown?
Yes. Our area takes in Chinatown and its surroundings, with estates and business parks such as Grand Vitesse Industrial Estate included. Photos and a short description are enough for a first look.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
What causes movement joint sealant to fail?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
What exactly is a movement joint?
The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably, and the sealing method is much the same.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Expansion joint sealing for commercial buildings in Chinatown
A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you have arrises breaking up along floor joints and new sealant over old, now failing, we can put it right, on car park decks and ramps, brickwork movement joints and cladding panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Chinatown, 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 Chinatown means thinking about access, loading times and the ULEZ as well as the joints.

What else we do in Chinatown
Commercial clients in Chinatown
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Expansion joint sealing in Chinatown: the local picture
In London, decks, bays and service yards usually have to keep running, so we seal in sections and hand areas back as each cures. At least three named trading, business or retail sites lie within about 3 miles of Chinatown. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Hospitals like Royal London Hospital for Integrated Medicine (0.9 miles north-east of Chinatown) have multi-storey or surface car parks whose joints carry vehicles round the clock. For a centre such as Brunswick Centre, which lies north of Chinatown, the service yard and car park joints usually need attention first.
Chinatown is about 1 mile east of City of Westminster, in Greater London. If you’re looking for expansion joint sealing in Chinatown, we can help, as we do across Greater London. Our Greater London coverage takes in 764 places, large and small.
We take on movement joints across the W1F, W1D and W1T postcode area. Among the streets we cover are Duck Lane, Drury Lane and Bruton Lane. With the A4 and A301 nearby, Chinatown is easy to get to with materials and equipment. Just outside Chinatown, we also work in Soho (1 mile north), St James's (1 mile south), West End (1 mile north-east), Seven Dials (1 mile north-east) and St Giles (1 mile north-east). Further afield, our area takes in Kensington (3 miles west), Shoreditch (3 miles north-east), Walthamstow (7 miles north-east), Hoxton (3 miles north-east), Whitechapel (3 miles east) and Hampstead (4 miles north-west).
Near you in Chinatown
We work on buildings around LITE Regal International School, London Library and Waxy O'Connor's pub and the streets around them. You will also find St Anne's Churchyard (less than half a mile north-west) and Harris Westminster Sixth Form (0.8 miles south). There’s a railway station in Chinatown itself: Tottenham Court Road station. A little further out are Leverian collection (under half a mile south-east) and Montfichet's Tower (1.3 miles east). Not far away are Barnsbury Wood and St. James's Park Lake.
Site staff or a sealant specialist?
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What we’re called out for in Chinatown
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.
Look out for the following:
- Layers of sealant in a movement joint
- Water dripping through deck or ramp joints
- Brittle, chalky sealant on external joints
- Movement joints with split or torn sealant
Another example is Southwark Bridge Business Centre, 1.6 miles east of Chinatown, where floors and yards would be done in stages around the occupiers.
What your quote should include
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
- How they handle RAMS and site documents
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Induction, permit and paperwork requirements
- Removal of failed or old sealant
- Joint width, depth and condition
- Which sealant the job calls for
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Whether an asbestos survey exists
- What the building is and how it’s used
- Any specification or named product
- Any dates the work must fit around
For a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
After the work
Regular inspection catches problems early. Specifically:
- Plan racking layouts so feet don’t land on a joint
- Inspect exposed joints once the cold weather has passed
- Put movement joints on the planned maintenance inspection round
- Brief car park operatives to protect joint lines during winter clearance
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.
How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Chinatown can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Getting the site ready
- Make sure the joints can be reached
- Tell us what induction or permit system the site runs
- Let building users know which areas are affected
