Facade sealing for businesses in Royal Docks

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Quoting for work in Royal Docks

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • How much there is to seal
  • Working within restricted access windows
  • Whether old sealant has to be cut out first

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

A few photos plus some basic facts will normally do. Please tell us:

  • The asbestos register, for older buildings
  • Any specification or named product
  • When you need the work done
  • Drawings or a marked-up plan, if available

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Facade sealing in Royal Docks

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters, and the usual reasons a site gets in touch are old perimeter mastic that has dried out and perimeter joints where frames meet the structure. A single leaking joint is often how a building in Royal Docks 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. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Facade sealing in Royal Docks: the local picture

Royal Docks has plenty of hotels close by, all within 2 miles. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Royal Docks 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.

Further education sites such as Newham College London, 1.7 miles to the north of Royal Docks, are extended and refurbished from time to time, with mastic often programmed into the summer break. On a campus such as University of East London, 0.9 miles east of Royal Docks, new teaching buildings and residences are usually built and refurbished around the academic year.

Royal Docks is about 1 mile south-east of Canning Town, in Greater London. If you’re looking for facade sealing in Royal Docks, we can help. Royal Docks is one of 764 places we cover in Greater London. We also cover London, some 6 miles away.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Joints whose design needs changing by the specifier
  • Render or concrete edges that have broken away
  • Work on the window or framing system itself

Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly.

Surfaces we seal

  • Stone and brick facade joints
  • Cladding panel joints
  • Shopfront frames
  • Perimeter joints where frames meet the structure
  • Window and door perimeters
  • Coping and flashing joints

When to bring in a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Redoing a failed joint typically 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.

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. Planning a London job such as one in Royal Docks starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Warn occupants and staff about the work
  • Send your site hours and access windows
  • Flag any permit to work we’ll need

Related advice

Royal Docks: questions and answers

Do you take on jobs in Royal Docks where loading and access are tightly controlled?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Is hospital work, at somewhere like Newham University Hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What the job involves on each surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.

Signs you need facade sealing in Royal Docks

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Most enquiries start with one or more of the following:

  • Unsightly perimeter sealant on a visible elevation
  • Cladding panel joints that have opened up
  • Water coming in around window frames
  • Sealant pulling away from frames or panels

Hotel extensions and refits, at places such as DoubleTree by Hilton Hotel London Excel, which lies west of Royal Docks, typically run between busy periods, so the sealing is squeezed into short windows.
