Do you need external mastic in Berrick Salome?
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall.
Most people get in touch when they notice one of these:
- Panel joints letting water in
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
If you live in an older home near Church of St Helen, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we handle external mastic in Berrick Salome
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on render & cladding joints, concrete & block and copings & trims, and common reasons people get in touch are rigid filler in a joint that should flex and joints where the bead has come unstuck.
Outside joints can only be sealed when they’re dry, so work in Berrick Salome is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, you get the same one-year guarantee.

How the job changes by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Act on the first splits you see
- Make sure movement joints aren’t pointed over
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access from start to finish. Somewhere like Berrick Salome needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

What external mastic looks like in Berrick Salome
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. Historic houses like Brightwell Manor (about 3.5 miles south-west) are a reminder that the area around Berrick Salome 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.
