External mastic in Sible Hedingham, done properly
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include movement joints with cracked, split or missing sealant and movement joints filled with mortar instead of sealant, on façade panels, concrete & block and copings & trims.
Homes around Sible Hedingham range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Each job carries a 12-month guarantee, whatever its size.

Honest limits
In fairness, some problems need a different trade:
- Structural movement, which needs a surveyor or engineer
- Damp that is not coming from the joint
- Cracked brickwork or render that needs a builder or plasterer

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Leave the joints unpainted unless we’ve said otherwise
- Never let anyone fill a movement joint with mortar
- Look over the joints every year, ideally after winter
- Keep water from gutters off the wall
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
External mastic in Sible Hedingham: local notes
With historic houses such as Hedingham Castle (about 1.1 miles north-east) nearby, there’s older building stock in the area around Sible Hedingham as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Hedingham School and Sixth Form, its movement joints, gutters and trims need looking after like any other building’s.

What affects the cost of external mastic
You’ll get a clear quote before work begins. It’s based on:
- The type of sealant required
- Any working-time requirements on site
- The amount of work
- The old material and how stubborn it is
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before any work starts.

Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. In a smaller place like Sible Hedingham, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

Related advice
When to call us in Sible Hedingham
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:
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
If you live in an older home near Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- How hidden problems are handled
- What product goes in the joint
- How much experience the applicator has
- When the joint can take water or movement
