About our external mastic in Angmering
For buildings in Angmering, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Typical jobs include old sealant gone brittle and cracked and failed sealant between panels on a façade, across concrete & block, copings & trims and render & cladding joints.
Homes around Angmering range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Our work is backed for twelve months.

Walls and rooflines in Angmering
Angmering is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around The Parish Church of St Margaret, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Angmering station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours to a few days, depending on the length of joint and the access. For a job in Angmering, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

Why it’s worth doing now in Angmering
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a smaller place like Angmering, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Instead of a standard rate, 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.

Common questions in Angmering
Do you work for landlords with property near Angmering station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Will you come out to Angmering?
Yes. Angmering is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
What should I tell you?
A short description and the location, plus photos if you have them. If we need more, we will ask.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

How we quote for external mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The amount of work
- Access and height
- The old material and how stubborn it is
- Any working-time requirements on site
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear price before work begins.
Asking for a quote
To help us quote quickly, let us know:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- If someone has resealed it before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
Do you need external mastic in Angmering?
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Look out for any of the following:
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
Managing a site like St Wilfrids Catholic Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Render that is blown, hollow or coming away
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that’s more than a sealant joint can take
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
