How we handle external mastic in Headbourne Worthy
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We work on concrete & block, brickwork movement joints and joints between brick and frames, and the jobs we see most are old sealant gone brittle and cracked and moss and dirt in joints with no sealant left.
Around Headbourne Worthy, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee, large or small.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Headbourne Worthy, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints

How to look after the new joints
Aftercare is simple:
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
- Wash walls gently around the sealant
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Signs you need external mastic in Headbourne Worthy
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
These are the problems we are asked about most:
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
Letting a property close to Winchester station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
- How much experience the applicator has
- When the joint can take water or movement
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Subsidence or other structural problems
- Damp that is not coming from the joint
- Cutting new joints into brickwork, which is building work rather than sealant work

FAQs for Headbourne Worthy
Can you help a landlord with a rental near Winchester station?

Is Headbourne Worthy within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.

Walls and rooflines in Headbourne Worthy
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.
For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Kings Worthy Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Why act early in Headbourne Worthy
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Headbourne Worthy, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
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 play a part, and we will explain the quote if you ask.
