Expansion joint sealing for commercial buildings in Brentford
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, so failed seals soon lead to leaks onto the level below and broken edges. 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. We work on brickwork movement joints, blockwork control joints and cladding panel joints, and what we are called in for most is hardened, cracked sealant on exposed facades and sealant peeling off one face of the joint. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Brentford it comes down to the same thing: the right product in a properly prepared joint.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Brentford, as everywhere in London, access, loading and the ULEZ all come into the plan.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Owners, agents and contractors
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Brentford can sit alongside others in a wider programme across Greater London.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Surface by surface
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints.

From enquiry to sign-off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. In Brentford, 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.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Warn occupants and staff about the work
- Move anything stored against the joints
- Confirm the product named in the specification
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
Advice
How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- How accessible the joints are
- The product specified
- Removal of failed or old sealant
- The total length or number of joints
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Clear photographs of the problem areas
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email the details over to discuss it first.
Common problems we fix in Brentford
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
Any of the following is a good reason to get the joints checked over:
- Previous reseals laid over old sealant
- Leaks through car park deck joints onto the level below
- Expansion joints split through the centre of the bead
- Chipped joint edges on forklift routes
Hospital campuses such as Clayponds Hospital (0.5 miles north-east of Brentford) grow in stages, leaving movement joints wherever new blocks meet old.
What your quote should include
- How they handle RAMS and site documents
- Will failed sealant be removed rather than covered?
- How they’ll work around occupants
- How the joint faces will be prepared and primed
Where floor joints take the most wear near Brentford
In London, decks, bays and service yards typically have to keep running, so the work is broken into short sections agreed with the building manager. At least three named trading, business or retail sites lie within about 3 miles of Brentford. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
If you manage units on an estate such as Phoenix Trading Estate, under half a mile to the north of Brentford, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Retail centres such as Kew Retail Park (to the south-east of Brentford) have floors, service yards and car parks with joints under constant traffic.
Brentford is about 2 miles south of Ealing, in Greater London. We send applicators to Brentford for movement joints, handled exactly as we handle every other area. We work across 764 places in Greater London, large and small. For work in that direction, see our London page.
Work on movement joints is covered throughout TW8, W3, W4 and W5. Buildings on High Street, Market Place and New Road are within our area. Brentford sits on or close to the A4 and A315, useful when we plan access and materials. We also cover Brentford End (1 mile south-west), Northfields (1 mile north-west), Gillette Corner (1 mile west), Isleworth (2 miles south-west) and Spring Grove (2 miles west) for movement joints. Nearby towns on our patch include London (9 miles east), City of Westminster (7 miles east), Marylebone (7 miles east), Kensington (4 miles east), St Pancras (8 miles east) and Shoreditch (10 miles east).
Local landmarks in Brentford
Around Brentford, our work takes us to commercial buildings near Library for Iranian Studies, Brentford School for Girls and Kew College Prep. Nearby too are The Brook pub (under half a mile south-west) and Kew Green (0.7 miles south-east). Brentford has its own railway station: Brentford station.

What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Proprietary pre-formed expansion joint systems
- Cracking or settlement that calls for an engineer’s assessment
If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer.
