How we handle external mastic in Kidmore End
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 façade panels, joints between brick and frames and copings & trims, and common reasons people get in touch are joints where the bead has come unstuck and damp patches traced to an open external joint.
In a village or hamlet like Kidmore End, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Our work is backed for twelve months.

Why act early in Kidmore End
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Kidmore End, wind-driven rain gets into any failed joint, 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 will talk you through it.

Honest limits
In fairness, some problems need a different trade:
- Render that is blown, hollow or coming away
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course

External mastic in Kidmore End: local notes
With historic houses such as Mapledurham House (about 2.3 miles south-west) nearby, there’s older building stock in the area around Kidmore End 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Tilehurst station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Kidmore End Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Is it worth trying it myself?

Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Act on the first splits you see
- Check the sealant is paintable before painting near it
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the building.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, 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.
