When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Facade sealing for commercial buildings in Bromley-by-Bow
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have perimeter joints where frames meet the structure and unsightly perimeter sealant on a visible elevation, we can put it right. A single leaking joint is often how a building in Bromley-by-Bow first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in a London area such as Bromley-by-Bow means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is normally 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 is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Common questions from Bromley-by-Bow clients
Do you cover business parks and estates near Bromley-by-Bow, such as Bow Enterprise Park?
Yes. We cover Bromley-by-Bow and the area around it, including industrial estates, business parks and retail parks such as Bow Enterprise Park. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
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.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Why act early in Bromley-by-Bow
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why appoint us
- Fully insured, including public liability cover
- Clear, fixed quotes
- Failed material removed, not covered up
- A range of standard colours, depending on the product

How the quote is worked out
The price varies from site to site. It mainly depends on:
- Working within restricted access windows
- Any access equipment needed
- The size and state of each joint
- Location, for remote and island sites
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Details that help us quote
However big the job, the same details help:
- Approximate linear metres or a joint schedule
- The postcode of the building
- Access details, including height
- What the building is and how it’s used
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
When to call us in Bromley-by-Bow
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.
Any of the following is a good reason to get the joints checked over:
- Old perimeter mastic that has dried out
- Perimeter sealant that has split or peeled away
- New sealant peeling off old mastic
- Failed sealant on precast panel joints
For contractors refurbishing units at places like Bow Enterprise Park, which lies south of Bromley-by-Bow, the mastic covers cladding panels, roller-door and window perimeters.
What your quote should include
- How the existing material will be dealt with
- What the guarantee covers, and for how long
- Proof of insurance
- The named product and why it was chosen
How the job changes by surface
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair first.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.

The ULEZ covers the whole of Greater London, Bromley-by-Bow included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Bromley-by-Bow takes in plenty of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

New wings at hospitals like Mile End Hospital (to the west of Bromley-by-Bow) bring long runs of window and panel joints to seal.

- We confirm the joint type, movement and the specified product.
