External mastic for homes and businesses in Shottenden
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. We are often asked to deal with movement joints with cracked, split or missing sealant and damp patches traced to an open external joint, on façade panels, joints between brick and frames and copings & trims.
In a village or hamlet like Shottenden, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
There’s a 12-month guarantee on every job.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the building. For a village or hamlet like Shottenden, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts

What else we do in Shottenden
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
External mastic in Shottenden: local notes
With historic houses such as Belmont House and Gardens (about 3.7 miles north-west) nearby, there’s older building stock in the area around Shottenden as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Ask before painting over external sealant
- Get split or bare joints resealed while the damage is small
- Tell anyone working on the walls about the movement joints
- Keep high-pressure jets off the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In a small place like Shottenden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Honest limits
In fairness, there are a few things sealant won’t fix:
- Failed render or damaged cladding panels
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What we’re called out for in Shottenden
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, and it tears off the sides.
The problems people generally mention when they call are:
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
Letting a property close to Selling station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- How the surfaces are prepared before sealing
- Is VAT in the price?
- Is the old sealant removed completely?
- How much experience the applicator has
