About our external mastic in Shottesbrooke
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Common call-outs are for leaking joints around cladding and façade panels and plants rooting in failed movement joints, on joints between brick and frames, brickwork movement joints and copings & trims.
Somewhere as small as Shottesbrooke, homes and farm buildings often face open ground, 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.
There’s a 12-month guarantee on every job.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint

Joints and surfaces we work on
- Concrete & block
- Copings & trims
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
When to call us in Shottesbrooke
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
These are the problems we’re asked about most:
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
For landlords with property near Twyford station, outside joints that have cracked can let damp into a rental, so check them between lets.

What happens on the day
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. Somewhere like Shottesbrooke 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.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
What external mastic looks like in Shottesbrooke
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Harleyford Manor (about 4.7 miles north) are a reminder that the area around Shottesbrooke 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.
In the older streets around Church of St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Cox Green School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Shottesbrooke is about 3 miles south-west of Maidenhead, in Windsor and Maidenhead.

Why act early in Shottesbrooke
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. Around Shottesbrooke, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Looking after it afterwards
Looking after new joints is easy:
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
