External mastic for homes and businesses in Newdigate
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on façade panels, joints between brick and frames and render & cladding joints, and people most often call us about joints pointed up with cement by mistake and weathered mastic that no longer stretches.
Older homes in small places like Newdigate may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Whatever the size of the job, it’s backed by our one-year guarantee in Newdigate and across Surrey.

What else we do in Newdigate
How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Newdigate, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Walls and rooflines in Newdigate
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 look after a building such as Newdigate CofE Endowed Aided Infant School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Holmwood station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain.

What affects the cost of external mastic

- The old material and how stubborn it is
- How many areas need sealing
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Newdigate: your questions answered
I let a flat near Holmwood station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Will you come out to Newdigate?
Yes, Newdigate is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch, so the joint stops doing its job. If it has already been filled, we can generally cut it out and reseal it.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Brickwork movement joints
- Façade panels
- Concrete & block
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Newdigate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
Why us?

Should I try it myself first?
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. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
