Facade sealing in London Fields

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in London Fields, done properly

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. Site teams most often ask us about new sealant peeling off old mastic and failed seals around shopfront and entrance frames, on coping and flashing joints, window and door perimeters and perimeter joints where frames meet the structure. A single leaking joint is often how a building in London Fields first comes to us: we look at the rest while we’re there and tell you what we find.

Around London Fields, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What happens if it’s left?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure, often turning up far from the joint. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. In London Fields, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Move anything stored against the joints
  • Confirm the product named in the specification
  • Send your site hours and access windows

Questions we’re asked in London Fields

Do you cover business parks and estates near London Fields, such as Bayford Street Industrial Centre?

Yes. We cover London Fields and the area around it, including industrial estates, business parks and retail parks such as Bayford Street Industrial Centre. Photos and a short description are enough for a first look.

Is a hospital such as Homerton University Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What affects the price in London Fields

Your fixed quote is built from the real scope. It takes account of:

  • Whether old sealant has to be cut out first
  • Phasing around occupants
  • The total length or number of joints
  • How accessible the joints are

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

We can often quote from photographs and a few details. It helps to include:

  • Your programme or deadline
  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call 01277 525 020 or send details through our quote form.

Looking after the joints

For the best life from the joints:

  • Inspect facade joints on a regular cycle
  • Keep pressure washers away from fresh sealant
  • Combine resealing with other works that need access
  • Clear debris that holds water against joints

Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

Doing it in-house

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Damp caused by condensation inside the building
  • Cracked or spalling substrates that need repair before sealing
  • Installing or repairing glazing systems

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Joints and surfaces we work on

  • Shopfront frames
  • Coping and flashing joints
  • Perimeter joints where frames meet the structure

Facades, frames and programmes in London Fields

Site traffic in London Fields falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A good number of hotels sit less than 2 miles from London Fields. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Hospital estates such as Homerton University Hospital, 1 mile to the north-east of London Fields, 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. Units on estates such as Bayford Street Industrial Centre (to the east of London Fields) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For contractors on a campus like Queen Mary University of London, which lies south-east of London Fields, facade and perimeter sealing has to fit around students and term dates.

London Fields is about 1 mile east of Hoxton, in Greater London. We cover commercial sites throughout London Fields, for single jobs and planned programmes alike. London Fields is one of 764 places we cover in Greater London.
