How we handle external mastic in Ospringe
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. We work on joints between brick and frames, brickwork movement joints and façade panels, and the jobs we see most are failed sealant between panels on a façade and plants rooting in failed movement joints.
Houses in smaller places like Ospringe can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.
Big or small, you get the same 12-month guarantee.

What we can’t put right
It helps to know what we cannot do:
- Movement that is more than a sealant joint can take
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint

Why act early in Ospringe
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 smaller place like Ospringe, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

What happens on the day
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building for a typical job. In a smaller place like Ospringe, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Before we arrive
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Ospringe: your questions answered
Can you do external mastic in Ospringe?
Yes, Ospringe is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Ospringe?
Yes, Ospringe is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render.
Are you fully insured?
Yes. We are fully insured.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
Walls and rooflines in Ospringe
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Belmont House and Gardens (about 3 miles south-west) nearby, there’s older building stock in the area around Ospringe 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.
In the older streets around Church of St Peter and St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Ospringe Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Faversham station, split movement joints are easy to miss on a rental until damp shows inside.
