How we handle external mastic in Pyrton
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 all tend to fail early. We strip the joint back and start again. We work on render & cladding joints, brickwork movement joints and façade panels, and the jobs we see most are old sealant gone brittle and cracked and plants rooting in failed movement joints.
In a village or hamlet like Pyrton, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It generally takes anything from a few hours to several days, depending on the building. For a village or hamlet like Pyrton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Keeping the joints in good condition
After the cure time, these simple habits help:
- Clear growth from the base of walls and joints
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
- Ask before painting over external sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for property managers and facilities teams. We can quote a run of properties together.
Outside joints around Pyrton
Historic houses like Adwell House (about 2.5 miles north) are a reminder that the area around Pyrton has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Watlington Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Around Pyrton
Around Pyrton, our work takes us to homes and buildings near All Saints Church, Icknield Community College and The Chequers pub, among other places. Green spaces nearby include Aston Rowant NNR and Bald Hill.
What we’re called out for in Pyrton
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
For an older house near a landmark such as St Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What sealant work cannot fix
