Expansion joint sealing in Cholsey
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we will confirm the choice in the quote. Site teams most often ask us about rain penetration at brick or block movement joints and water dripping through deck or ramp joints, across podiums and floor movement joints, car park decks and ramps and cladding panel joints.

From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If neighbouring businesses or buildings around Cholsey need work too, visits can be combined. Tell us your site hours and we will plan around them.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Have the specification and drawings to hand
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements

Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Keeping the joints sound
To get the most from the new sealant:
- Look over external and deck joints after a hard winter
- Put movement joints on the planned maintenance inspection round
- Treat a small split as a warning, not a cosmetic issue
- Raise snow-clearing blades over deck joints where possible
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.
Common problems we fix in Cholsey
Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.
What tends to prompt an enquiry:
- Sealant pulling off the joint face
- Rain penetration at brick or block movement joints
- Expansion joints filled with dirt and stones
- Car park joints leaking onto vehicles below
Hospitals like Wallingford Community Hospital (1.8 miles north-east of Cholsey) have multi-storey or surface car parks whose joints carry vehicles round the clock.
What your quote should include
- The named product and why it was chosen
- Can the work be phased to keep areas open?
- The terms of the workmanship guarantee
- Whether primer will be used where the manufacturer specifies it
Common questions from Cholsey clients
Is hospital work, at somewhere like Wallingford Community Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is a smaller place like Cholsey outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Why has the sealant in our expansion joints split?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first since each needs a different fix.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Are expansion joints and movement joints the same thing?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What happens if it’s left?
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why us?
- Coloured sealants to suit the setting, where available

What the job involves on each surface
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Slabs, ramps and loading bays in Cholsey
Rainfall across the South East, Cholsey included, is lower than in many parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. Cholsey lies roughly 46 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day.
If you manage units on an estate such as Hithercroft Industrial Estate, 1.8 miles north of Cholsey, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Schools like Cholsey Primary School often have long brick elevations with movement joints that age quietly.
