Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Keeping the joints sound
A few simple habits keep the new joints working:
- Check sealant joints during planned building inspections
- Keep a record of when each building was resealed
- Encourage occupiers to report problems at frames
- Share the asbestos register when you send details
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Mastic sealing in Chinatown
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. If you are dealing with a mix of products and colours from past repairs and worn sealant at communal door frames, we can put it right, whatever the surface. Whoever orders the work in Chinatown, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Chinatown
The edges of the material itself sometimes break away for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
What tends to prompt an enquiry:
- A mix of products and colours from past repairs
- Worn sealant at communal door frames
- Repeated reactive repairs to the same buildings
- Draught complaints from residents or tenants
Blocks of flats and mixed-use buildings often cluster around stations such as Tottenham Court Road station (to the north of Chinatown) and their window and balcony mastic tends to age at the same rate across a building.
Before you book anyone
- How they’ll work around occupants
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Who will actually carry out the work
- Is the sealant right for the movement and the substrate?
Cost factors for mastic joints
These are the things that shape the price:
- Access and working height
- How much there is to seal
- Phasing around occupants
- Joint width, depth and condition
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- Drawings or a marked-up plan, if available
- Any specification or named product
- The type of building and who uses it
- The site address and postcode
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.
Looking after buildings in and around Chinatown
Blocks in London are typically run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We work to your notice and access plan.
Older community buildings, St Anne's Church among them, often have frames of mixed ages whose mastic varies. If you own or manage units on a site such as Grand Vitesse Industrial Estate (1.4 miles east of Chinatown), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Chinatown is about 1 mile east of City of Westminster, in Greater London. Businesses, contractors and managing agents in Chinatown use us for work on mastic joints, as part of our coverage of Greater London. We work across 764 places in Greater London, large and small.
Business premises anywhere in W1F, W1D and W1T are within our area for mastic joints. We cover commercial and managed buildings on Duck Lane, Drury Lane and Bruton Lane and the roads nearby. Chinatown sits on or close to the A4 and A301, useful when we plan access and materials. Nearby places we also cover include 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). A short drive away, we cover 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).
What’s near Chinatown
We work on buildings around LITE Regal International School, London Library and Waxy O'Connor's pub, among other places. You’ll also find St Anne's Churchyard (less than half a mile north-west) and Harris Westminster Sixth Form (0.8 miles south). Chinatown has its own railway station: Tottenham Court Road station. Well-known places in the area include Leverian collection (under half a mile south-east) and Montfichet's Tower (1.3 miles east). Open spaces near Chinatown include Barnsbury Wood and St. James's Park Lake.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If you’re not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.
What we seal
- Shopfronts below residential blocks
- Balcony and threshold joints
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
Common questions from Chinatown clients
Can you work at a site such as Grand Vitesse Industrial Estate, by Chinatown?
Yes. Our area takes in Chinatown 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.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is Chinatown in your area?
Yes. Chinatown is in our area. For a quote, ring 01277 525 020 or email us.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
General trades versus a specialist
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. Getting these wrong usually costs more in the end than doing them right.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
How a job runs
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. In Chinatown, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Tell us your opening times and when work is allowed
- Flag any permit to work we will need
- Agree which areas must stay open
