Expansion joint sealing for commercial buildings in Westwick Row
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic. If you are dealing with hardened, cracked sealant on exposed facades and debris jammed in movement joints, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Westwick Row from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In and around smaller places like Westwick Row, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Maintenance after handover
Once the work is signed off, these steps help:
- Report split or peeling joint sealant early
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Plan racking layouts so feet don’t land on a joint
- Look over external and deck joints after a hard winter
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.
Signs you need expansion joint sealing in Westwick Row
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.
It’s worth sending us details if you spot any of the following:
- Damp inside where a wall movement joint has failed
- Brittle, chalky sealant on external joints
- Joints packed with grit and debris
- New sealant over old, now failing
On industrial estates such as Saracen Industrial Estate (1.2 miles north-west of Westwick Row), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Who will actually carry out the work
- What level of public liability insurance do they hold?
- What the guarantee covers, and for how long
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Surfaces we seal
- Blockwork control joints
- Cladding panel joints
- Car park decks and ramps
- Precast concrete panel joints
- Brickwork movement joints
- Podiums and floor movement joints
On site: what to expect
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, then handed back before we move to the next. Smaller jobs around Westwick Row can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- 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 tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- 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.
Preparing the site
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work
- Agree which areas must stay open

Warehouse floors and decks around Westwick Row
At about 22 miles from central London, Westwick Row is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Westwick Row sits in or beside Hemel Hempstead, a twentieth-century planned town. Its industrial areas were laid out from the start, and units built in the same decades tend to have slabs and movement joints that age in step; one programme for a whole row of units is often simplest.
Schools such as Leverstock Green Church of England Primary School have movement joints in their walls and floors that are easy to overlook. At places like McDonald Business Park, 1.5 miles to the north-west of Westwick Row, joints are sealed a section at a time so operations carry on.
Westwick Row is about 2 miles east of Hemel Hempstead, in Hertfordshire. We cover Westwick Row, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 371 places in Hertfordshire, large and small. For work in that direction, see our London page.

Just outside Westwick Row, we also work in Leverstock Green (1 mile west), Bennetts End (1 mile west), Pimlico (1 mile south), Adeyfield (1 mile west) and Hemel Hempstead (2 miles west).

What’s near Westwick Row
Locally, jobs take us to sites close to Longdean School. The nearest railway station is Apsley station, roughly 2.1 miles south-west of the centre. A little further out are Village Arcade St Albans (3.4 miles east) and Hemel Hempstead Hospital (2.1 miles west). Green spaces nearby include Verulamium Lake and Long Deans.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Questions we’re asked in Westwick Row
Does your area include sites such as Saracen Industrial Estate, near Westwick Row?
Yes, sites like Saracen Industrial Estate are within our area, along with the rest of Westwick Row. A few photos and the unit address let us price the work.
Our unit in Hemel Hempstead is decades old: is it worth resealing the floor joints?
Typically, yes, as long as the joint edges are still sound. We’ll look at the joints, recommend a product for the traffic and movement, and say if any edges need repair before sealing.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Why do our movement joints keep failing?
The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
What if the joint edges are damaged?
Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.
