Expansion joint sealing for Wherwell sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Put movement joints on the planned maintenance inspection round
- Keep traffic off new joints until the cure time is up
- Check joints after long freezing spells
- Raise snow-clearing blades over deck joints where possible
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
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.
How we handle expansion joint sealing in Wherwell
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. Most enquiries involve layers of sealant in a movement joint and sealant peeling off one face of the joint, on cladding panel joints, brickwork movement joints and podiums and floor movement joints. Whoever orders the work in Wherwell, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places such as Wherwell, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Wherwell need work, visits can be combined. You’ll have a fixed quote before work starts.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
Getting the site ready
- Have the specification and drawings to hand
- Share your working hours and any access restrictions
- Agree which areas must stay open

Advice
When to call us in Wherwell
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.
These are often picked up first by site or facilities staff:
- Weathered movement joint sealant that no longer flexes
- Leaks through car park deck joints onto the level below
- Damp inside where a wall movement joint has failed
- Sealant pulling off the joint face
If you manage units on an estate such as Harewood Forest Industrial Estate, 1.9 miles to the north-east of Wherwell, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.
What your quote should include
- Proof of insurance
- What site paperwork they can supply
- What the guarantee covers, and for how long
- Who will actually carry out the work
Why deal with it now?
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall. Resealing early keeps the work to sealant. Converted and older buildings near places like Wherwell tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Slabs, ramps and loading bays in Wherwell
At about 63 miles from central London, Wherwell is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift. The South East is one of the drier parts of the UK. External joints still wait for dry conditions, while winter salting gets into any joint left open.
A healthcare site such as Andover War Memorial Hospital, 4 miles north-west of Wherwell, depends on car parks, ramps and service yards whose joints take traffic all day. For a school such as Wherwell Primary School, playground and building joints can be done in the holidays.
Wherwell is about 3 miles south-east of Andover, in Hampshire. Our applicators travel to Wherwell for work on movement joints. Wherwell is one of 723 places we cover in Hampshire for movement joints. Sites around Southampton have their own page, about 17 miles away.

Local landmarks in Wherwell
We work on buildings around White Lion Public House and Longstock Park, among other places. The closest station to Wherwell is Andover station, about 3.7 miles north-west of the centre. Other landmarks nearby include Andover Museum (3.3 miles north-west) and Andover War Memorial Hospital (4 miles north-west). Not far away are Mill Lake and Anton Lakes.
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Your questions answered
Is Harewood Forest Industrial Estate, near Wherwell, within your area?
Yes. We cover Wherwell and the area around it, including industrial estates, business parks and retail parks such as Harewood Forest Industrial Estate. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Would you work within a site like Andover War Memorial Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
