Contractors’ notes for London Docklands
Site traffic in London Docklands falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. London Docklands has a good number of hotels close by, all within 2 miles. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Hotels like London Marriott Hotel Canary Wharf, under half a mile north-west of London Docklands, rarely close for long, so refurbishment mastic is phased floor by floor. Hospital estates such as The London Independent Hospital, 1.6 miles north-west of London Docklands, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. For contractors at a college like New City College (under half a mile north of London Docklands), perimeters and internal sealant are timed for the holidays.
London Docklands is about 2 miles north-west of Greenwich, in Greater London. We cover London Docklands and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. London Docklands is one of 764 places we cover in Greater London.

Facade sealing in London Docklands, done properly
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. We work on shopfront frames, window and door perimeters and cladding panel joints, and the usual reasons a site gets in touch are previous reseals run over old sealant and unsightly perimeter sealant on a visible elevation. A single leaking joint is often how a building in London Docklands first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Owners, agents and contractors
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Cost factors for facade joints
We price every job individually. The things that drive the figure:
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- The product specified
- Working within restricted access windows
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- The site address and postcode
- Asbestos survey details if the building is older
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Joints whose design needs changing by the specifier
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Damaged frames that need replacing
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Different surfaces, different methods
Precast concrete panels
Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod, primed where the maker specifies.
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, as the specification sets out.
From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. All of Greater London is in the ULEZ, and kerbside space in London Docklands can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Before we start on site
- Let us know about inductions and permits
- Warn occupants and staff about the work
- Share your working hours and any access restrictions

London Docklands: questions and answers
Can you work on a hospital site such as The London Independent Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you take on work at estates like Poplar Business Park, close to London Docklands?
Yes, sites like Poplar Business Park are within our area, along with the rest of London Docklands. Photos and a short description are enough for a first look.
Can the sealant be colour-matched?
It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you cover London Docklands?
Yes. We take on work across London Docklands.
Why act early in London Docklands
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
