How we handle external mastic in Shedfield
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, leaving it bonded to two faces so it can move with the wall. We work on copings & trims, render & cladding joints and concrete & block, and the jobs we see most are hard, crazed mastic that has stopped moving and movement joints filled with mortar instead of sealant.
Somewhere as small as Shedfield, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Signs you need external mastic in Shedfield
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
The most common problems we see are:
- Failed sealant between panels on a façade
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
If you live in an older home near Church of St John, older walls, gutters and the joints where extensions meet them need a flexible sealant.

FAQs for Shedfield

Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.

Why act early in Shedfield
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Shedfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

How the job changes by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Outside joints around Shedfield
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Botley station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as St John the Baptist Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
