About our external mastic in Tangmere
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you have hard, crazed mastic that has stopped moving and failed sealant between panels on a façade, we can help.
Outbuildings, garages and conservatories around homes in places like Tangmere add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
You get a one-year guarantee, the same in Tangmere as everywhere else we work.

How to look after the new joints
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Check external joints each spring
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Quotes for external mastic in Tangmere
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- How much there is to do
- The type of sealant required
- The number of rooms or windows
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
Helping us quote
To make quoting easier, please include:
- Whether it has been sealed before
- Roughly how big the job is
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we will take it from there.
Tangmere buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Goodwood House (about 1.8 miles north-west) are a reminder that the area around Tangmere 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.
If you look after a building such as Tangmere Primary Academy, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near St Andrew's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Advice
When to call us in Tangmere
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Look out for any of the following:
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
Letting a property close to Chichester station? Then split movement joints are easy to miss on a rental until damp shows inside.
Before booking anyone
- How long to leave it before use
- Are they insured?
- Who does the work, and how experienced they are
- What product goes in the joint

Why it’s worth doing now in Tangmere
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Tangmere, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
