External mastic for homes and businesses in Mill Street
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. Common call-outs are for rain getting behind render or cladding at a joint and plants rooting in failed movement joints, on concrete & block, brickwork movement joints and façade panels.
Outside joints can only be sealed when they’re dry, so work in Mill Street is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Honest limits
We will not take on work that will not last, so here’s what sealant can’t put right:
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.
Joints and surfaces we work on
- Concrete & block
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
What the job involves on each surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check external joints each spring
- Ask before painting over external sealant
- Have failed joints looked at early
- Do not let climbing plants root in the sealant
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.

What external mastic looks like in Mill Street
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Stoke-by-Nayland Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

- How many rooms, windows or areas are involved
- Mould in or behind the old joints

What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The rough size of the job
- Whether it has been sealed before
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Mill Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
How to get a quote
Every job is quoted individually. Just ring 0345 464 0079 or drop us an email with the details, and pictures are welcome.

Why act early in Mill Street
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Mill Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
