Facade sealing in Chinatown, done properly
Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. Site teams most often ask us about damp patches beside frames after rain and failed sealant on precast panel joints, across cladding panel joints, shopfront frames and coping and flashing joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Chinatown, preparation and product choice get the time they need.
Around Chinatown, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Signs you need facade sealing in Chinatown
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.
Things that typically lead to an enquiry:
- Air leaks through failed facade joints
- Unsightly perimeter sealant on a visible elevation
- New sealant peeling off old mastic
- Weathered joints at frame-to-structure perimeters
For contractors at a college like Westminster Kingsway College Soho Centre (less than half a mile north-west of Chinatown), perimeters and internal sealant are timed for the holidays.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Installing or repairing glazing systems
- Joints too narrow for the movement they take, which need redesign
- Specialist high-level access methods
Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.
Joints and surfaces we work on

Why act early in Chinatown
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Failed sealant in a building in Chinatown can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Your questions answered
Will you take on work at estates like Grand Vitesse Industrial Estate, close to Chinatown?
Yes. Estates, retail parks and business parks around Chinatown, Grand Vitesse Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Is hospital work, at somewhere like Royal London Hospital for Integrated Medicine, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
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 where general trades tend to cut corners.
Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Planning a London job such as one in Chinatown starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Point out any areas we must not close
- Confirm the product named in the specification
- Share the asbestos register for older buildings

Advice
Mastic packages on Chinatown sites
As part of Greater London, Chinatown is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. Plenty of hotels sit less than 2 miles from Chinatown. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
On a healthcare site such as Royal London Hospital for Integrated Medicine, which lies north-east of Chinatown, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors on a campus like University of Notre Dame, under half a mile to the south of Chinatown, facade and perimeter sealing has to fit around students and term dates.
Chinatown is about 1 mile east of City of Westminster, in Greater London. Businesses, contractors and managing agents in Chinatown can call on us for facade 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. We cover commercial and managed buildings on Duck Lane, Drury Lane and Bruton Lane. Chinatown sits on or close to the A4 and A301, useful when we plan access and materials. Sites close to Chinatown are covered too, including 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).
Around Chinatown
Around Chinatown, our work takes us to commercial buildings near LITE Regal International School, London Library and Waxy O'Connor's pub. Other local landmarks include St Anne's Churchyard (under 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. Other landmarks nearby include Leverian collection (less than half a mile south-east) and Montfichet's Tower (1.3 miles east). Green spaces nearby include Barnsbury Wood and St. James's Park Lake.
After the work
Keep the joints in good shape with a few simple steps:
- Note when each elevation was last resealed
- Never let anyone seal over old sealant
- Brief window cleaners about newly sealed joints
- Ask about asbestos in pre-2000 mastic
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
