Facade sealing for Lower Clapton sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

About our facade sealing in Lower Clapton

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. If you’re dealing with patch repairs that keep failing and water coming in around window frames, we can help, whatever the surface. One point of contact handles commercial sealant work in Lower Clapton from the first photographs to the final walk-round, for single jobs and planned programmes alike.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.

A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, give us a call on 01277 525 020 or email us and we will come back to it.

Questions about Lower Clapton

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. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for

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

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you look at water coming in around a frame?

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

How do I request a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What affects the price in Lower Clapton

Before we quote, we look at:

  • Whether old sealant has to be cut out first
  • How much there is to seal
  • How accessible the joints are
  • Joint width, depth and condition

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Where the site is, with the postcode
  • The product your specification calls for
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or use the quote form.

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Damaged frames that need replacing
  • Installing or repairing glazing systems
  • Specialist high-level access methods

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Facades, frames and programmes in Lower Clapton

As part of Greater London, Lower Clapton is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. The area within 2 miles of Lower Clapton holds plenty of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.

Units on estates such as Bayford Street Industrial Centre (0.9 miles south-west of Lower Clapton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Building work at universities like Loughborough University London, 1.1 miles east of Lower Clapton, is often timed for the summer, mastic included.

Lower Clapton is about 2 miles north-east of Hoxton, in Greater London. Commercial clients in Lower Clapton can call on us for facade joints. Across Greater London, 764 places are covered, Lower Clapton among them.

Different surfaces, different methods

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

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.

Site staff or a sealant specialist?

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. Getting these wrong typically costs more in the end than doing them right.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. For a job in Lower Clapton, access comes first. Send the building rules and access times with your enquiry.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000
  • Tell us what induction or permit system the site runs

Related advice

Do you need facade sealing in Lower Clapton?

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Look out for the following:

  • New sealant peeling off old mastic
  • Sealant pulling away from frames or panels
  • Perimeter joints where frames meet the structure
  • Leaks at window and door perimeters

Work at a hotel such as Kip Hotel (to the south-west of Lower Clapton) tends to be programmed around bookings, mastic included.
