External mastic in Stroude
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. If you have hard, crazed mastic that has stopped moving and movement joints with cracked, split or missing sealant, we can put it right, whatever the surface.
In a village or hamlet like Stroude, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap.
Why deal with it now?
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Around Stroude, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

When something else is needed
A few problems are outside what sealant work can do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
- Movement that’s more than a sealant joint can take
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before you book.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. For a village or hamlet like Stroude, the journey is planned in advance: 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 inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Advice
Stroude buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Botleys Mansion (about 2.7 miles south) are a reminder that the area around Stroude has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Virginia Water station, split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Christ Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common problems we fix in Stroude
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
People generally contact us when they notice something like this:
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
- Moss and dirt in joints with no sealant left
If you look after a building such as St Ann's Heath Junior School, its movement joints, gutters and trims need looking after like any other building’s.
