Expansion joint sealing for commercial buildings in Matching Green
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. If you have spalled or broken joint edges in floors and decks and leaks through car park deck joints onto the level below, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Matching Green, preparation and product choice get the time they need.
In and around smaller places like Matching Green, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Questions about Matching Green
Is Matching Green too small for you to travel to?
Not at all. Matching Green is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is hospital work, at somewhere like Princess Alexandra Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators.
How long does movement joint sealing take?
Allow a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We confirm the timescale with the quote.
Do you use silicone or polyurethane in movement joints?
The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane.
Can you work while the building is occupied?
In most cases, yes. Phased work can be planned so areas stay in use.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What the job involves on each surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Damaged metal nosings or cover plates over a joint
- Broken or spalled joint edges, which need repairing before any sealant goes in
If you are not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer.

Warehouse floors and decks around Matching Green
Matching Green is about 24 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Matching Green is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
Around Matching Green, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Do you need expansion joint sealing in Matching Green?
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.
Clients usually get in touch after noticing something like this:
- Water dripping through deck or ramp joints
- Arrises breaking up along floor joints
- Brittle, chalky sealant on external joints
- Damp inside where a wall movement joint has failed
Sites like Princess Alexandra Hospital, 6 miles to the west of Matching Green, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Matching Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000

Advice
What happens if it’s left?
Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s typically not far behind, and a second visit means paying for access again. Where it helps, we quote both options. One visit to deal with every failing joint makes more sense than several trips to a place like Matching Green, rather than one at a time. Send photographs of each area and we will quote for the lot.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
