Facade sealing across Plaistow

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

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Plaistow can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  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. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Flag any permit to work we’ll need
  • Send your site hours and access windows

How we handle facade sealing in Plaistow

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. Site teams most often ask us about gaps between rainscreen or cladding panels and patch repairs that keep failing, on shopfront frames, cladding panel joints and stone and brick facade joints. Facilities teams, main contractors and managing agents in Plaistow tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Facades, frames and programmes in Plaistow

Site traffic in Plaistow 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. A 2-mile radius around Plaistow takes in plenty of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

Recladding or extending a unit at a site like Mint Business Park (to the south of Plaistow) brings panel joints and frame perimeters into the programme. On a healthcare site such as Newham University Hospital, which lies east of Plaistow, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Plaistow is about 5 miles east of London, in Greater London. Across the E13 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Greater London, 764 places are covered, including Plaistow.

Plaistow: questions and answers

Can you take on a job at a hospital such as Newham University Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work around term dates at a campus such as University of East London?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

What type of sealant goes on window perimeters?

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, and we work to what is specified.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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, as the specification sets out.

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.

Signs you need facade sealing in Plaistow

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

Things that normally lead to an enquiry:

  • Failed sealant on precast panel joints
  • Unsightly perimeter sealant on a visible elevation
  • Cold air coming in at window perimeters
  • Perimeter joints where frames meet the structure

When a college such as Newham College London (0.5 miles north-east of Plaistow) builds or refurbishes, the mastic package typically has to fit around students and staff.

What your quote should include

  • The named product and why it was chosen
  • How the existing material will be dealt with
  • How the joint faces will be prepared and primed
  • How joint depth will be controlled
