External mastic for homes and businesses in Snoll Hatch
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you’re dealing with weeds or debris growing in open joints and old sealant gone brittle and cracked, we can help, on façade panels, copings & trims and concrete & block alike.
Outside joints can only be sealed when they’re dry, so work in Snoll Hatch is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job.

Honest limits
In fairness, some problems need a different trade:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.
Surfaces we seal
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Concrete & block
Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
External mastic in Snoll Hatch: local notes
With historic houses such as Old Soar Manor (about 4.5 miles north-west) nearby, there’s older building stock in the area around Snoll Hatch as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of the Holy Trinity include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Beltring station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as East Peckham Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Make sure movement joints are not pointed over
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Look over the joints every year, ideally after winter
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Snoll Hatch can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
