Aldermaston External Mastic
Professional external mastic in and around Aldermaston, with every bit of old sealant taken out first.
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels
- Damp that isn’t coming from the joint
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
- Joints between brick and frames
- Façade panels
- Copings & trims
External mastic in Aldermaston, done properly
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Typical jobs include joints pointed up with cement by mistake and movement joints with cracked, split or missing sealant, across brickwork movement joints, joints between brick and frames and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Aldermaston is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Aldermaston questions
Can you do external mastic in Aldermaston?
Yes. Our work covers London and the South East, and Aldermaston is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is Aldermaston within the area you cover?
Yes, Aldermaston is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins from the range available.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What the job involves on each surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Send us any details you have about the façade.
Do you need external mastic in Aldermaston?
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Look out for these signs:
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
Letting a property close to Aldermaston station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Outside joints around Aldermaston
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Aldermaston C.E. Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Aldermaston, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
