Joints that move: notes for Barking
Barking has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. London car parks, loading bays and podium decks often can’t close for long, so joints are sealed in sections with each area handed back once cured.
Hospital campuses such as Barking Community Hospital, under half a mile to the north of Barking, grow in stages, leaving movement joints wherever new blocks meet old. Phasing is what makes joint work possible on busy sites such as Barking Business Centre (0.7 miles south-east of Barking): one bay, aisle or car park row at a time.
Barking is about 9 miles east of London, in Greater London. Commercial clients in Barking use us for work on movement joints. Barking is one of 764 places we cover in Greater London for movement joints. We also cover London, around 9 miles from Barking.
Postcode districts covered here: IG11, RM9, RM8 and E6 for movement joints. Among the streets we cover are Eastbury Square, London Road and Church Road, and sites on any of them can send details for a fixed quote. If your building is just outside Barking, we cover Loxford (1 mile north-west), Creekmouth (1 mile south), Wallend (1 mile west), East Ham (2 miles west) and Beckton (2 miles south-west). Nearby towns on our patch include London (9 miles west), City of Westminster (11 miles west), Marylebone (11 miles west), Kensington (13 miles west), St Pancras (9 miles west) and Shoreditch (8 miles west).

The closest station to Barking is Barking station, roughly 0.8 miles north-west of the centre.

About our expansion joint sealing in Barking
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. Site teams most often ask us about brittle, chalky sealant on external joints and torn sealant in brick or block movement joints, on brickwork movement joints, podiums and floor movement joints and precast concrete panel joints. Looking for mastic applicators who cover Barking? We’ve been sealing commercial buildings since 2005.
Around Barking, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Questions we’re asked in Barking
Would you work within a site like Barking Community Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Lyon Business Park, near Barking, within your area?
Yes. We cover Barking and the area around it, including industrial estates, business parks and retail parks such as Lyon Business Park. Send details of the unit and the work through our quote form for a quick quote.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How much does the work cost?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What’s the difference between an expansion joint and a movement joint?
The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped, and the sealing method is much the same.
What else we do in Barking
Signs you need expansion joint sealing in Barking
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.
Most enquiries start with something like this:
- Damp inside where a wall movement joint has failed
- Leaks through car park deck joints onto the level below
- New sealant over old, now failing
- Spalled or broken joint edges in floors and decks
Business parks such as Lyon Business Park (to the south of Barking) have car parks, paved areas and long brick and panel elevations, all with movement joints.
Comparing quotes
- Can the work be phased to keep areas open?
- How they handle RAMS and site documents
- Do they follow the manufacturer’s priming guidance?
- Is the sealant right for the movement and the substrate?
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Movement on a scale no sealant is meant to absorb
- Joints too narrow for the movement, which need redesigning by the engineer
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.
Surfaces we seal
- Precast concrete panel joints
- Cladding panel joints
- Car park decks and ramps
- Brickwork movement joints
- Podiums and floor movement joints
- Blockwork control joints
Looking after the joints
To get the most from the new sealant:
- Clear dirt from joint lines during routine cleaning
- Plan racking layouts so feet don’t land on a joint
- Report split or peeling joint sealant early
- Keep scrapers and ploughs from dragging across joint sealant
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Sealing early protects the edges.
On site: what to expect
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, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- Send any specification or drawings in advance
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Advice
What happens if it’s left?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. Getting scaffold, permits or access booked in Barking takes effort, so it makes sense to deal with every failing joint while access is in place.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
