Akeley External Mastic
We cover Akeley for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
Looking after it afterwards
So the new joints stay in good condition:
- Wash walls gently around the sealant
- Leave the joints unpainted unless we have said otherwise
- Make sure movement joints are not pointed over
- Clear growth from the base of walls and joints
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
External mastic for homes and businesses in Akeley
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on façade panels, copings & trims and joints between brick and frames, and the jobs we see most are plants rooting in failed movement joints and rain getting behind render or cladding at a joint.
External sealant needs dry, clean surfaces, so work around Akeley is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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, then guaranteed for a year.
When to call us in Akeley
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
It’s worth asking for a quote if you see:
- Panel joints letting water in
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Joints with sealant missing in places
If you live in an older home near Church of St Mary (Assumption of the Blessed Virgin Mary), an extension built onto an older house moves differently, and the joint between them takes the strain.
Before booking anyone
- How long to leave it before use
- How the joint is cleaned and prepared
- Whether they’re fully insured
- Whether you can choose the colour
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Akeley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

External mastic in Akeley: local notes
Historic houses like Stowe House (about 2.1 miles west) are a reminder that the area around Akeley has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Akeley Wood Senior School, its movement joints, gutters and trims need looking after like any other building’s.

What the job involves on each surface
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Akeley needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip 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.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
