Construction mastic in West Silvertown
We work to the specification and the programme. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you have caulk cracking where joints are moving more than expected and frame perimeters left unsealed or poorly sealed, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in West Silvertown is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Every London site, West Silvertown included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites usually need booked deliveries and a plan for where materials go.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Have the specification and drawings to hand
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
Get a fixed quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

What we’re called out for in West Silvertown
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Clients typically get in touch after noticing one or more of the following:
- Inconsistent sealant finishes from plot to plot
- Internal caulk splitting as the building dries out
- Early adhesion failures on new external joints
- Snag items on joints that need redoing before handover
Hospital estates such as Newham University Hospital, 1.4 miles north of West Silvertown, 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.

When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, 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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

How the job changes by surface
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room.
