How we handle construction mastic in Canary Wharf
The specification and the programme set the job, not to habit. Where the specification names a product, we use it. Backing, primer and depth follow what the sealant maker sets out. If you’re dealing with a mastic package split between trades with no clear owner and perimeter gaps outside the sealant’s range, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Canary Wharf is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Canary Wharf must meet its standards or pay the daily charge. Alongside that, sites usually need booked deliveries and a plan for where materials go.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Our process
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. In Canary Wharf, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Tell staff and tenants when we will be in
- Flag any permit to work we will need
Getting a fixed quote
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email drawings and photos.

Your questions answered
Is Poplar Business Park, near Canary Wharf, within your area?
Yes. Our area takes in Canary Wharf and its surroundings, with estates and business parks such as Poplar Business Park included. Photos and a short description are enough for a first look.
Do you take on jobs in Canary Wharf where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry.
Does weather affect external mastic work?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure so it’s better to wait.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
What does a mastic package typically include?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Can you work plot by plot or floor by floor?
Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team and updated as the programme moves.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- Site requirements such as inductions and permits
- Whether the work must be split into stages
- How much existing material needs removing
- The total length or number of joints
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
To get a fixed quote, give us a call on 01277 525 020 or send photos by email with the site address and an outline of the work. You can also send details through our quote form.
Leave it or put it right?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference. Where an alternative is genuinely suitable, we’ll say so. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Contractors’ notes for Canary Wharf
A 2-mile radius around Canary Wharf takes in plenty of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Canary Wharf included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Hotels like London Marriott Hotel Canary Wharf, under half a mile north-west of Canary Wharf, rarely close for long, so refurbishment mastic is phased floor by floor. Units on estates such as Poplar Business Park, 0.5 miles north-east of Canary Wharf, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Canary Wharf is about 2 miles north-west of Greenwich, in Greater London. Commercial clients in Canary Wharf use us for work on mastic packages. Our Greater London coverage takes in 764 places, from busy centres to rural villages.
Business premises anywhere in E14, SE16 and E22 are within our area. Buildings on Castor Lane, Cassilis Road and Dockyard Lane are within our area. Canary Wharf sits on or close to the A1261. Nearby places we also cover include London Docklands (1 mile east), Poplar (1 mile north-east), Heron Quays (1 mile south-west), Coldharbour (1 mile east) and Blackwall (1 mile east) for mastic packages.

Local landmarks in Canary Wharf
Locally, jobs take us to sites close to Tower Hamlets College, Sir John McDougall Gardens and The Ledger Building pub and the streets around them. There’s a railway station in Canary Wharf itself: Canary Wharf station. Nearby you’ll also find The Pumphouse Educational Museum (0.8 miles west) and Surrey Quays Shopping Centre (1.4 miles south-west). Open spaces near Canary Wharf include St. James's Park Lake and Tower Hill.
Signs you need construction mastic in Canary Wharf
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Site and facilities staff are often the first to spot these:
- Sealant knocked or painted over by other trades
- External joints sealed in damp or cold conditions that are now failing
- A long mastic snag list close to completion
- Internal caulk splitting as the building dries out
Building work at universities like University of Sunderland in London, less than half a mile south-east of Canary Wharf, is often timed for the summer, mastic included.

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
What the job involves on each surface
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.
