About our expansion joint sealing in Westcot
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed. We seal and reseal movement joints in walls, panels, decks and floors on sites in Westcot. We work on brickwork movement joints, car park decks and ramps and podiums and floor movement joints, and the failures we are asked to look at most are leaks through car park deck joints onto the level below and chipped joint edges on forklift routes. Whoever orders the work in Westcot, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller community and commercial buildings around Westcot have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
When you manage a building on behalf of an owner, 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.
Warehouse floors and decks around Westcot
Central London is about 61 miles from Westcot. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Westcot sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.
Large sites such as Faringdon Day Hospital, 5.8 miles north-west of Westcot, have car parks, service roads and long elevations with movement joints in brick and panels. On industrial estates such as W&G Industrial Estate, which lies east of Westcot, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Westcot is about 4 miles west of Wantage, in Oxfordshire. We cover commercial sites throughout Westcot. 423 places across Oxfordshire fall within our area, including Westcot. Sites around Oxford have their own page, roughly 16 miles from Westcot.
Work on movement joints is covered throughout OX12. If your building is just outside Westcot, we cover Sparsholt (1 mile east), Kingston Lisle (1 mile west), Woolstone (3 miles west), Upper Lambourn (5 miles south) and Sheepdrove (5 miles south). Bigger towns within reach include Didcot (11 miles east), Abingdon-on-Thames (12 miles north-east), Witney (14 miles north), Carterton (13 miles north), Wantage (4 miles east) and Grove (4 miles east).
What’s near Westcot
Nearby you’ll also find Faringdon Day Hospital (5.8 miles north-west) and Uffington Museum (2.5 miles west). The countryside around Westcot includes Rams Hill and Letcombe Valley.
Why act early in Westcot
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. One visit to deal with every failing joint makes more sense than several trips to a place like Westcot, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.

Common questions from Westcot clients
Is a smaller place like Westcot outside your area?
No. Places such as Westcot are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you work on a hospital site such as Faringdon Day Hospital?
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.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Are expansion joints and movement joints the same thing?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing and both need a flexible seal.
Do the joint edges need to be sound before sealing?
Spalled edges need repairing before a new seal will last and we will flag every length affected. Sealing over them leads to early failure.
When to call us in Westcot
Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises. A sealant that isn’t trafficable won’t last there.
Any of the following is a good reason to get the joints checked over:
- Arrises breaking up along floor joints
- Movement joints with split or torn sealant
- Sealant pulling off the joint face
- Water getting into the wall through a failed joint
At places like Grove Business Park, 3 miles to the east of Westcot, joints are sealed a section at a time so operations carry on.
Questions to ask before you book
- How the joint faces will be prepared and primed
- Who will actually carry out the work
- How the existing material will be dealt with
- How joint depth will be controlled
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Proprietary pre-formed expansion joint systems
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Changing the joint layout or spacing of a structure
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. If others near Westcot need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Confirm the product named in the specification
- Clear stock, furniture or equipment away from the joints
