About our external mastic in Sayers Common
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. We work on concrete & block, joints between brick and frames and copings & trims, and people most often call us about water getting into walls through failed joints and gaps where render, brick and frames meet.
In a village or hamlet like Sayers Common, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common problems we fix in Sayers Common
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
These are the problems we’re asked about most:
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
- Failed sealant between panels on a façade
For an older house near a landmark such as Christ Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Sayers Common buildings and the weather
Historic houses like Ockenden Manor (about 4.6 miles north-east) are a reminder that the area around Sayers Common 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Hassocks station? Then split movement joints are easy to miss on a rental until damp shows inside. Schools such as Albourne CofE Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Keeping the joints in good condition
Aftercare is simple:
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
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.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
Surface by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. For a village or hamlet like Sayers Common, 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.
- 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
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises

Sayers Common questions
Can you do external mastic in Sayers Common?
Yes. Our work covers London and the South East, and Sayers Common is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Do you cover smaller places like Sayers Common?
Yes. Sayers Common is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
How long does external mastic take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We’ll confirm how long when we quote.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
How we quote for external mastic
The price is agreed before any work begins. It’s based on:

- Photos by email, if that’s easy
