About our external mastic in Lower Burgate
For buildings in Lower Burgate, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you have movement joints filled with mortar instead of sealant and water getting into walls through failed joints, we can help, whatever the surface.
Around Lower Burgate, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What external mastic looks like in Lower Burgate
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 Breamore House (about 2.2 miles north) are a reminder that the area around Lower Burgate has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as The Burgate School and Sixth Form, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.

What affects the cost of external mastic
There’s no set price list. What we look at:
- Whether the work is at height
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Combining jobs into one visit usually makes better use of the time than several visits. We will give you a clear quote for the lot.

- Any previous sealing or DIY work
- Any access issues, like height or stairs

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
Signs you need external mastic in Lower Burgate
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
People normally contact us when they notice something like this:
- Failed seals between different materials
- Failed sealant between panels on a façade
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
For an older house near a landmark such as St Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why it’s worth doing now in Lower Burgate
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Lower Burgate, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
Why us?
- Domestic, commercial and hotel work
- White, clear, grey or another colour, product permitting
- Anti-fungal silicone where joints get wet
- You choose the colour before work begins
Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Tell us what the building has when you get in touch.
