Why it’s worth doing now in Downside
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open without shutting the whole car park. We agree phasing with you before work starts. One visit to deal with every failing joint makes more sense than several trips to a place like Downside. Send photos of each area and we’ll quote for the lot.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Expansion joint sealing in Downside, done properly
Brickwork and blockwork walls have vertical movement joints at intervals 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 with primer where the maker calls for it. We work on brickwork movement joints, podiums and floor movement joints and car park decks and ramps, and what we’re called in for most is spalled or broken joint edges in floors and decks and previous reseals laid over old sealant. A single leaking joint is often how a building in Downside first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Jobs around smaller places like Downside are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What else we do in Downside
Where floor joints take the most wear near Downside
The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Downside lies roughly 19 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.
For a school such as St Matthew's CofE Aided Infant School, playground and building joints can be done in the holidays. On industrial estates such as Bookham Industrial Estate, which lies south-east of Downside, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Downside is about 4 miles west of Leatherhead, in Surrey. Anywhere in KT11, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Surrey, 379 places are covered, Downside among them. Sites around London have their own page, about 19 miles away.
Postcode districts covered here: KT11 for movement joints. Buildings on Downside Common, Downsview Close and Deacon Close are within our area. Sites close to Downside are covered too, including Hatchford (1 mile west), Martyr's Green (1 mile south-west), Hatchford End (2 miles west), Whiteley Village (3 miles north) and Wisley (3 miles west). Nearby towns on our patch include Guildford (8 miles south-west), Woking (7 miles west), Camberley (14 miles west), Epsom (6 miles east), Horley (14 miles south-east) and Redhill (12 miles south-east).
Near you in Downside
We work on buildings around The Plough Public House and Parkside School and the streets around them. Downside’s nearest station is Cobham & Stoke Dabernon station, roughly 1 mile north-east of the centre. Nearby you’ll also find Epsom Cottage Hospital (5.1 miles north-east) and Send and Ripley History Society Museum (3.8 miles west). The countryside around Downside includes Jubilee Wood and Boldermere Lake.
What the job involves on each surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Damaged metal nosings or cover plates over a joint
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Waterproofing layers buried beneath the sealant
If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think before you book.
What we seal
- Cladding panel joints
- Podiums and floor movement joints
- Precast concrete panel joints
- Car park decks and ramps
- Brickwork movement joints
- Blockwork control joints
Downside: questions and answers
Is Downside off your patch?
Not at all. Downside is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work on a hospital site such as Cobham Community Hospital and Health Centre?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Why has the sealant in our expansion joints split?
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.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Can you work on car park ramps and decks?
Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Downside can sit alongside others in a wider programme.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around Downside can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.

- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Share the asbestos register for older buildings

Advice
When to call us in Downside
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.
What tends to prompt an enquiry:
- Rain penetration at brick or block movement joints
- Hardened, cracked sealant on exposed facades
- Spalled or broken joint edges in floors and decks
- Joints packed with grit and debris
Hospitals like Cobham Community Hospital and Health Centre (1.6 miles north of Downside) have multi-storey or surface car parks whose joints carry vehicles round the clock.
What to look for in a quote
- Will RAMS and insurance details be available?
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
