External mastic in Aldermaston Wharf, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We are often asked to deal with old sealant gone brittle and cracked and failed sealant between panels on a façade, across render & cladding joints, concrete & block and copings & trims.
Older homes in small places like Aldermaston Wharf may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
All of our work is guaranteed for twelve months, in Aldermaston Wharf and everywhere else we cover.

What we are called out for in Aldermaston Wharf
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
Keep an eye out for these signs:
- Sealant that has lost its bond to the brick or render
- Old sealant gone brittle and cracked
- Failed seals between different materials
- Joints with sealant missing in places
In the older streets around Church of St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Aldermaston Wharf, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

How we quote for external mastic
Call for a quick quote. The main things that affect it are:
- The size of the job
- The product the joint needs
- The number of rooms or windows
- Whether the work is at height
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. The price is agreed before we begin.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- How we’d reach the joints

Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.

Aldermaston Wharf questions
Do you cover Aldermaston Wharf for external mastic?
Yes, Aldermaston Wharf is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Is Aldermaston Wharf within the area you cover?
Yes, Aldermaston Wharf is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. We’ll reseal it with a flexible sealant.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you reach joints on upper floors?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Walls and rooflines in Aldermaston Wharf
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Aldermaston station, outside joints that have cracked can let damp into a rental, so check them between lets.
