Facade sealing for commercial buildings in Spitalfields

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you have perimeter sealant that has split or peeled away and staining on stone next to old sealant, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Spitalfields it comes down to the same thing: the right product in a properly prepared joint.

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.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Building and refurbishing in Spitalfields

There are plenty of hotels within about 2 miles of Spitalfields. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. Site traffic in Spitalfields falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

Hotels like Hotel Saint (under half a mile south of Spitalfields) rarely close for long, so refurbishment mastic is phased floor by floor. For contractors refurbishing units at places like Princes Court Business Centre (0.9 miles south-east of Spitalfields), the mastic covers cladding panels, roller-door and window perimeters. Building work at universities like London Metroplitan University: Aldgate Campus (under half a mile south-east of Spitalfields) is often timed for the summer, mastic included.

Spitalfields is about 1 mile north-east of London, in Greater London. Spitalfields sits inside our coverage and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. 764 places across Greater London fall within our area, including Spitalfields.

Business premises anywhere in E1, EC2A and E1W are within our area. Among the streets we cover are New Road, Mark Lane and Bell Lane, and sites on any of them can send details for a fixed quote.

Maintenance after handover

A few simple habits keep the new joints working:

  • Avoid harsh cleaners on facade sealant
  • Keep sills, gutters and drainage paths clear
  • Inspect facade joints on a regular cycle
  • Never let anyone seal over old sealant

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.

Common questions from Spitalfields clients

Can you work at a site such as Princes Court Business Centre, by Spitalfields?

Yes. Estates, retail parks and business parks around Spitalfields, Princes Court Business Centre among them, are all within reach. A few photographs and the unit address let us price the work.

Can work at a site such as London Metroplitan University: Aldgate Campus fit around teaching?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How do I request a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

How long does a job like this take?

That varies with the scale of the job, but the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you provide access for facade work?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Providing access systems for the work
  • Joints whose design needs changing by the specifier
  • Water getting in through cracked render or porous masonry

If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Where we work in Spitalfields

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

Surface by surface

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone.

Leave it or put it right?

Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. 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.

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.

Commercial clients in Spitalfields

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. 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 plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.
