Facade sealing in Plaistow, done properly
Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. We work on window and door perimeters, stone and brick facade joints and cladding panel joints, and the failures we’re asked to look at most are old perimeter mastic that has dried out and draughts around frames and panels. One point of contact handles commercial sealant work in Plaistow from the first photos to the final walk-round, for single jobs and planned programmes alike.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Check that rainwater leaves the facade the way it was designed to
- Walk the elevations once or twice a year
- Record the product and colour used on each elevation
- Brief window cleaners about newly sealed joints
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a job in Plaistow, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
What we need from you
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space

Advice
What the job involves on each surface
Render and coated surfaces
Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them.
Common questions from Plaistow clients
Would you work within a site like Sloane Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work in a London building with booked loading and goods-lift slots?
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. The ULEZ covers the whole of Greater London, which we allow for
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
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. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
How much does the work cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Facade sealing in Plaistow: the local picture
Site traffic in Plaistow 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. The area within 2 miles of Plaistow holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
University estates such as University of Greenwich - Avery Hill, 3.5 miles to the north-east of Plaistow, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Projects at colleges like Hadlow College, 1.7 miles to the north-east of Plaistow, tend to run to term dates, so the mastic is planned tightly.
Plaistow is about 1 mile north of Bromley, in Greater London. If you are looking for facade sealing in Plaistow, we can help, as we do across Greater London. Our Greater London coverage takes in 764 places. We also cover London, some 7 miles away.
We take on facade joints across the BR1, BR2 and BR3 postcode area, whatever the building. For a building on Saxon Road, Arcus Road and Croft Road or nearby, send details and we’ll quote for facade joints. Nearby places we also cover include Downham (1 mile north), Sundridge (1 mile east), Grove Park (1 mile north-east), Bromley (1 mile south) and Chinbrook (1 mile north-east). Nearby towns on our patch include London (7 miles north-west), City of Westminster (10 miles north-west), Marylebone (10 miles north-west), Kensington (11 miles north-west), St Pancras (9 miles north-west) and Shoreditch (8 miles north-west).

What we can’t put right

- Movement beyond what any sealant can handle
- Specialist high-level access methods
- Damp caused by condensation inside the building

Do you need facade sealing in Plaistow?
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.
Common reasons buildings call us in:
- Air leaks through failed facade joints
- New sealant peeling off old mastic
- Gaps between rainscreen or cladding panels
- Discoloured or dirty facade joints
New units and refits on sites such as Chartwell Business Centre, 1.8 miles south-east of Plaistow, need their panel and perimeter joints sealed to the specification.
