FAQs: Donnybrook Quarter

Is a hospital such as Mile End Hospital somewhere you can work?

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.

Can work at a site such as University of Staffordshire London Campus fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

About our facade sealing in Donnybrook Quarter

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. Most enquiries involve patch repairs that keep failing and old perimeter mastic that has dried out, across coping and flashing joints, perimeter joints where frames meet the structure and window and door perimeters. Looking for mastic applicators who cover Donnybrook Quarter? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Every London site, Donnybrook Quarter included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, ring 01277 525 020 or send photos by email and we’ll come back to it.

Facade sealing in Donnybrook Quarter: the local picture

The ULEZ covers the whole of Greater London, Donnybrook Quarter included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are a good number of hotels within about 2 miles of Donnybrook Quarter. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Building work at universities like University of Staffordshire London Campus (0.8 miles north of Donnybrook Quarter) is often timed for the summer, mastic included. Projects at colleges like International College of Musical Theatre (0.6 miles north of Donnybrook Quarter) tend to run to term dates, so the mastic is planned tightly.

Do you need facade sealing in Donnybrook Quarter?

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

Common reasons buildings call us in:

  • Draughts around frames and panels
  • Previous reseals run over old sealant
  • Gaps between rainscreen or cladding panels
  • Perimeter joints where frames meet the structure

For a contractor at a hotel such as City View Hotel, less than half a mile south-west of Donnybrook Quarter, the mastic often has to be finished before a reopening date.

Our contractor checklist

How a job runs

In a busy building, 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 the next one starts. In Donnybrook Quarter, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  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.

What we need from you

  • Share the asbestos register for older buildings
  • Confirm the product named in the specification
  • Tell staff and tenants when we’ll be in

Related advice

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Keeping the joints sound

For the best life from the joints:

  • Check that rainwater leaves the facade the way it was designed to
  • Add perimeter sealant to planned maintenance checks
  • Check the asbestos register before old mastic is disturbed
  • Note when each elevation was last resealed

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal across the elevation.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

Why deal with it now?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
