About our external mastic in Stambourne
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on render & cladding joints, brickwork movement joints and façade panels, and people most often call us about movement joints with cracked, split or missing sealant and water getting into walls through failed joints.
Older homes in small places like Stambourne may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Every job is covered by a one-year guarantee, wherever you are in Essex.

How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Stambourne needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Outside joints around Stambourne
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hedingham Castle (about 4.6 miles south-east) are a reminder that the area around Stambourne 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.
In and around Stambourne, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Stambourne: your questions answered
Is there a guarantee on external mastic in Stambourne?
All our work, in Stambourne and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Stambourne within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Stambourne.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
When to call us in Stambourne
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
Most people get in touch when they notice one of these:
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
Homes close to Parish Church of St Peter and St Thomas include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that’s more than a sealant joint can take
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Different surfaces, different methods
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and helps it last.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Stambourne can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
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 make a difference.
