Facade sealing in Hoxton, done properly

Access is part of every facade job, and we plan it with you before quoting. 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. If you have previous reseals run over old sealant and water coming in around window frames, we can help. Whoever orders the work in Hoxton, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Hoxton must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

Our workmanship is guaranteed for 12 months, in Hoxton as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Hoxton: questions and answers

Do you work in London buildings with loading restrictions?

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’ll plan accordingly.

Do you take on work at healthcare sites like Moorfields Eye Hospital (City Road campus)?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work while the building is occupied?

Usually, yes. We phase the work so most of the building stays in use.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How is access to upper-level joints handled?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and we’ll price the work around it.

Leave it or put it right?

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: 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.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Public liability insurance in place
  • Work carried out by CSCS-carded applicators

Take a look at what affects the cost and our accreditations.

Cost factors for facade joints

Quotes vary with the job. It mainly depends on:

  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Details that help us quote

To price the job accurately, we need to understand the site. Send us:

  • Specification clauses that apply
  • The postcode of the building
  • The asbestos register, for older buildings
  • Clear photos of the problem areas

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or send photos by email with what you know.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. We look at the joints, the drawings and the access before pricing.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open
  • Tell us your opening times and when work is allowed

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Building owners, agents and FMs in Hoxton

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Hoxton can form part of a wider programme across Greater London.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Maintenance after handover

After handover, a little attention goes a long way:

  • Insist on a full cut-out when joints are renewed
  • Brief window cleaners about newly sealed joints
  • Share access with other external trades
  • Note when each elevation was last resealed

After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.

Sites and facades in and around Hoxton

There are plenty of hotels within about 2 miles of Hoxton. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The ULEZ covers the whole of Greater London, Hoxton 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.

When units on a site such as Bayford Street Industrial Centre, 1.3 miles to the east of Hoxton, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Work at a hotel such as Courthouse Hotel Shoreditch, 0.5 miles south-east of Hoxton, tends to be programmed around bookings, mastic included. For contractors at a college like New City College, less than half a mile to the south-east of Hoxton, perimeters and internal sealant are timed for the holidays.
