About our mastic sealing in Plaistow

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Most enquiries involve mastic failing across several blocks on an estate and occupiers reporting cold air round windows, on communal entrances and stairwells, external wall and movement joints and balcony and threshold joints. Whoever orders the work in Plaistow, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Frames that are rotten, warped or broken
  • Masonry that has broken away beside the joint
  • Leaks from above rather than through a joint

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

Surfaces we seal

  • Shopfronts below residential blocks
  • External wall and movement joints
  • Communal entrances and stairwells
  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • Communal kitchens and washrooms

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. In Plaistow, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Advice

Your questions answered

Can you quote for a block close to West Ham station?

Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.

Does your area include sites such as Mint Business Park, near Plaistow?

Yes. Estates, retail parks and business parks around Plaistow, Mint Business Park among them, are all within reach. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do you check for asbestos in old sealant?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

What about access for upper-floor joints?

Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

General trades versus a specialist

Certain joints really need a specialist: for instance 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.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common problems we fix in Plaistow

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

It’s worth sending us details if you spot any of the following:

  • Complaints coming in block by block
  • Brittle perimeter mastic across a building
  • Damaged joints in communal entrances and corridors
  • Water getting in round frames after rain

For agents with blocks near West Ham station, 0.9 miles to the west of Plaistow, a block-wide mastic programme deals with frames, balconies and entrances in one go.
