External mastic in Wotton: local notes
Historic houses like Polesden Lacey (about 3 miles north) are a reminder that the area around Wotton has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Gomshall station, split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as The Priory CofE Voluntary Aided School, its movement joints, gutters and trims need looking after like any other building’s.

External mastic for homes and businesses in Wotton
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. Typical jobs include weathered mastic that no longer stretches and panel joints letting water in, on façade panels, copings & trims and render & cladding joints.
In a village or hamlet like Wotton, 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.
You get a one-year guarantee, the same in Wotton as everywhere else we work.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not let climbing plants root in the sealant
- Avoid pressure-washing directly into sealant joints
- Ask before painting over external sealant
- Keep water from gutters off the wall
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.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Do you need external mastic in Wotton?
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Any of these means the joints need attention:
- Old sealant gone brittle and cracked
- Damp patches traced to an open external joint
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
Homes close to Church of St John the Evangelist include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. In a small place like Wotton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

Wotton questions
Do you work for landlords with property near Gomshall station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Wotton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you have insurance?
Yes. We’re fully insured.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
What should I tell you?
Tell us what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In a small place like Wotton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.
