External & façade joints in Bishopstoke, Hampshire
External mastic across Bishopstoke and nearby, with every bit of old sealant taken out first.
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
- Rain getting behind render or cladding at a joint
What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.
External mastic for homes and businesses in Bishopstoke
For buildings in Bishopstoke, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on brickwork movement joints, façade panels and copings & trims, and the jobs we see most are damp patches traced to an open external joint and brick movement joints where the sealant has split.
Outbuildings, garages and conservatories around homes in places like Bishopstoke add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Every job comes with our 12-month guarantee, wherever you are in Hampshire.

Common questions in Bishopstoke
Is Bishopstoke in your area for external mastic?
Yes. We work across London and the South East, and Bishopstoke is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Bishopstoke?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
How do I get a quote for external mastic in Bishopstoke?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Landlord and commercial work in Bishopstoke
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- The product the joint needs
- The size of the job
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Any access issues, like height or stairs
- The problem you’ve noticed
- Photos by email, if that’s easy
- Where the job is, and your postcode
For external mastic in Bishopstoke, ring 0345 464 0079 or email us. Tell us what the problem is and where, and you will get a clear quote before we start.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
- Check external joints each spring
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
What happens if it’s left?
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Bishopstoke, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. For a job in Bishopstoke, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints

Common problems we fix in Bishopstoke
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
The most common problems we see are:
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
In the older streets around St Paul's, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic in Bishopstoke: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like South Stoneham House (about 3 miles south-west) are a reminder that the area around Bishopstoke has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Eastleigh station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Stoke Park Junior School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
