Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Expansion joint sealing for commercial buildings in Childrey
Brickwork and blockwork walls have vertical movement joints at intervals. 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. Most enquiries involve water dripping through deck or ramp joints and damp inside where a wall movement joint has failed, across brickwork movement joints, podiums and floor movement joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Childrey is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller community and commercial buildings around Childrey have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. Smaller jobs around Childrey can be grouped with others nearby. You will have a fixed quote before work starts.
- Photos, joint lengths and drawings come to us, or we visit.
- 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.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Share the asbestos register for older buildings
- Let us know about inductions and permits

- Waterproofing layers buried beneath the sealant
- A joint that has to be widened or re-detailed before it can work
- Concrete or masonry repairs along the arrises

Why it’s worth doing now in Childrey
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. For buildings around smaller places like Childrey, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

FAQs: Childrey
Can you work on a hospital site such as Wantage Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Childrey off your patch?
Not at all. Childrey is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Why do our movement joints keep failing?
It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
How long does movement joint sealing take?
It typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We will confirm when each area can be used again.
Building owners, agents and FMs in Childrey
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Warehouse floors and decks around Childrey
Childrey is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. Childrey lies roughly 60 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.
Warehouse floors on estates like W&G Industrial Estate (1.1 miles north-east of Childrey) carry pallet trucks and forklifts over every saw-cut joint. Hospital campuses such as Wantage Community Hospital, 2.6 miles to the east of Childrey, grow in stages, leaving movement joints wherever new blocks meet old. In a school such as The Ridgeway Church of England (C) Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep scrapers and ploughs from dragging across joint sealant
- Treat a small split as a warning, not a cosmetic issue
- Note which joints were done, when, and with what
- Inspect exposed joints once the cold weather has passed
Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it. Regular sweeping keeps joint lines clear.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.
