External Mastic in Emberton
Movement joints in Emberton need attention? We cut out the old, prepare the joints and apply the right sealant.
- Joints pointed up with cement by mistake
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Somewhere as small as Emberton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Advice
External mastic in Emberton, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. We work on render & cladding joints, façade panels and concrete & block, and the jobs we see most are sealant that has lost its bond to the brick or render and leaking joints around cladding and façade panels.
In a village or hamlet like Emberton, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.

How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Do you need external mastic in Emberton?
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
- Sealant pulling away from one side of the joint
If you look after a building such as Emberton School, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- What product goes in the joint
- How long to leave it before use
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
Aftercare tips
To keep the joints looking good and working properly:
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Wash walls gently around the sealant
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together. Around Emberton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What else we do in Emberton
External mastic in Emberton: local notes
Historic houses like Turvey Abbey (about 4.1 miles north-east) are a reminder that the area around Emberton has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of All Saints include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
