External mastic in Row Heath, done properly
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. If you have joints with sealant missing in places and panel joints letting water in, we can put it right, on copings & trims, joints between brick and frames and concrete & block alike.
Around Row Heath, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Where a wall is exposed, as many are in small places like Row Heath, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Point out the joints to other trades
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

Signs you need external mastic in Row Heath
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
Keep an eye out for these signs:
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
If you look after a building such as Engaines Primary School and Nursery, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Walls and rooflines in Row Heath
With historic houses such as Thorpe Hall (about 2.5 miles north-east) nearby, there’s older building stock in the area around Row Heath as well as newer homes. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St James, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Weeley station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
