How we handle external mastic in Aldington
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. We’re often asked to deal with hard, crazed mastic that has stopped moving and failed sealant between panels on a façade, across brickwork movement joints, concrete & block and copings & trims.
In a village or hamlet like Aldington, 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.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Send us any details you have about the façade.
Aldington: your questions answered
Do you work for landlords with property near Ham Street station?

What is backing rod for?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we’ll do them. Tell us about the building and we’ll confirm what access is needed.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.

Why it’s worth doing now in Aldington
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Aldington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

Aldington buildings and the weather
Historic houses like Westenhanger Castle (about 3.9 miles east) are a reminder that the area around Aldington 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Ham Street station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Aldington Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St Martin, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How to look after the new joints
After the cure time, these simple habits help:
- Wash walls gently around the sealant
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
- Deal with leaking gutters that soak the joints below
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
When it is not the sealant
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer
- Adding movement joints to masonry that has none
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. Somewhere like Aldington needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
