Common questions from Bow clients
Does your area include sites such as Old Ford Trading Estate, near Bow?
Yes, sites like Old Ford Trading Estate are within our area, along with the rest of Bow. Send details of the unit and the work through our quote form for a quick quote.
Can you take on a job at a hospital such as Mile End Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is movement joint sealing guaranteed?
The 12-month guarantee applies to the workmanship. Tell us straight away if a joint we sealed gives trouble in that time.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Why it’s worth doing now in Bow
Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we will tell you they need repairing first. Failed sealant in a building in Bow can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Expansion joint sealing around Bow: what changes locally
The 3 miles around Bow take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. In London, decks, bays and service yards typically have to keep running, so we seal in sections and hand areas back as each cures.
Campuses like Queen Mary University of London (0.7 miles south-west of Bow) mix old and new buildings, with movement joints wherever they meet. Phasing is what makes joint work possible on busy sites such as Stour Road Industrial Estate (0.5 miles north of Bow): one bay, aisle or car park row at a time.

Common problems we fix in Bow
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Typical triggers for a call:
- Debris jammed in movement joints
- Chipped joint edges on forklift routes
- Car park joints leaking onto vehicles below
- Movement joints with split or torn sealant
Hospitals like Mile End Hospital (to the south-west of Bow) have multi-storey or surface car parks whose joints carry vehicles round the clock.

What the job involves on each surface
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Close-up photos help us judge the joints.
How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For a job in Bow, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
