Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
How we handle external mastic in Alphamstone
For buildings in Alphamstone, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We’re often asked to deal with damp patches traced to an open external joint and moss and dirt in joints with no sealant left, on brickwork movement joints, joints between brick and frames and copings & trims.
Older homes in small places like Alphamstone may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why act early in Alphamstone
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. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Alphamstone can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before any work starts, matched as closely as the range allows.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Alphamstone needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Walls and rooflines in Alphamstone
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. With historic houses such as Gainsborough's House (about 3.6 miles north) nearby, there’s older building stock in the area around Alphamstone as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Parish Church of St Barnabas, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Bures station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
