About our external mastic in Buckland Common
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. We are often asked to deal with moss and dirt in joints with no sealant left and weathered mastic that no longer stretches, across concrete & block, joints between brick and frames and render & cladding joints.
In a village or hamlet like Buckland Common, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, you get the same one-year guarantee in Buckland Common and across Hertfordshire.

What we cannot put right
In fairness, there are a few things sealant will not fix:
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels

Surfaces we seal
- Concrete & block
- Façade panels
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
What affects the quote in Buckland Common
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- Any working-time requirements on site
- Any mould that needs treating
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

What external mastic looks like in Buckland Common
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. With historic houses such as Cholesbury Manor House (about 0.6 miles east) nearby, there’s older building stock in the area around Buckland Common 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 St Lawrence, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.

Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Common problems we fix in Buckland Common
Some movement joints have been pointed up with mortar. The joint cannot move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
For landlords with property near Wendover station, split movement joints are easy to miss on a rental until damp shows inside.
