What happens if it’s left?
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Around Amberley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.

External mastic in Amberley
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you’re dealing with panel joints letting water in and sealant that has lost its bond to the brick or render, we can help, on render & cladding joints, copings & trims and brickwork movement joints alike.
Around Amberley, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job, whatever its size.

What else we do in Amberley
Signs you need external mastic in Amberley
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
The problems people generally mention when they call include:
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Old sealant gone brittle and cracked
- Failed seals between different materials
If you look after a building such as Amberley CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- How much experience the applicator has
- What preparation is included
How to look after the new joints
So the new joints stay in good condition:
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Make sure movement joints aren’t pointed over
- Avoid pressure-washing directly into sealant joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.
What affects the quote in Amberley
We quote each job individually. These are the things that affect it:
- Which sealant suits the joint
- When we can work, for business premises
- Access and height
- Mould in or behind the old joints
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’ll know the price before we begin.
Asking for a quote
When you call or email, these details help:
- Where the property is
- The problem you’ve noticed
- If someone has resealed it before
- Whether it’s a home or a business
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.
What we cannot put right
A few problems are outside what sealant work can do:
- Cracked brickwork or render that needs a builder or plasterer
- Failed render or damaged cladding panels
- Subsidence or other structural problems
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Landlord and commercial work in Amberley
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
How it works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the building in most cases. Somewhere as small as Amberley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Related advice
External mastic in Amberley: local notes
With historic houses such as Parham House (about 1.9 miles east) nearby, there’s older building stock in the area around Amberley as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For an older house near a landmark such as The Parish Church of St Michael and All Angels, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Amberley station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
