External & façade joints in Braishfield, Hampshire
Our applicators work in Braishfield on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
- Movement joints with cracked, split or missing sealant
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.

External mastic in Braishfield
On houses, flats and commercial buildings across Braishfield, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We’re often asked to deal with movement joints with cracked, split or missing sealant and failed sealant between panels on a façade, across render & cladding joints, copings & trims and brickwork movement joints.
Around Braishfield, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee, whatever its size.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
External mastic in Braishfield: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Mottisfont Abbey (about 3.3 miles north-west) nearby, there’s older building stock in the area around Braishfield as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Braishfield Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Romsey station, outside joints that have cracked can let damp into a rental, so check them between lets.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Your questions about external mastic in Braishfield
Is Braishfield in your area for external mastic?
Yes, Braishfield is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Do you cover smaller places like Braishfield?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Landlord and commercial work in Braishfield
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

What else we do in Braishfield
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Where a wall is exposed, as many are in small places like Braishfield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is usually more efficient than separate visits. We will give you a clear quote for the lot.

Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
The process
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of joints, longer for a whole elevation from start to finish. Somewhere as small as Braishfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
