The process
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Church End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Advice
External mastic in Church End
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We are often asked to deal with damp patches traced to an open external joint and weathered mastic that no longer stretches, on façade panels, brickwork movement joints and copings & trims.
Somewhere as small as Church End, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
You get a one-year guarantee, the same in Church End as everywhere else we work.

Signs you need external mastic in Church End
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
The most common problems we see are:
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
In the older streets around Church of St. Leonard, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Before you book anyone
- When the joint can take water or movement
- How the colour is chosen
- Which sealant they’ll use, and why
- What guarantee comes with the work
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
- Fix overflowing gutters above sealed joints
- Ask before painting over external sealant
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What external mastic looks like in Church End
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. Historic houses like The Vyne (about 2.5 miles west) are a reminder that the area around Church End has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Bramley (Hants) station? Then split movement joints are easy to miss on a rental until damp shows inside. Managing a site like The Loddon School? Then larger buildings have long runs of movement joint that eventually need resealing.

Different surfaces, different methods
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
