External & façade joints in Wicken Bonhunt, Essex
Professional external mastic in and around Wicken Bonhunt, with every bit of old sealant taken out first and a 12-month guarantee.
- Sealant that has lost its bond to the brick or render
- Weathered mastic that no longer stretches
- Failed sealant between panels on a façade
How we handle external mastic in Wicken Bonhunt
On houses, flats and commercial buildings across Wicken Bonhunt, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on concrete & block, façade panels and render & cladding joints, and the jobs we see most are sealant that has lost its bond to the brick or render and rigid filler in a joint that should flex.
Somewhere as small as Wicken Bonhunt, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

How the job changes by surface
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.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- The type of sealant required
- Mould in or behind the old joints
- When we can work, for business premises
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- Roughly how big the job is
- Any access issues, like height or stairs
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we’ll come back to you with a quote.
Why deal with it now?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Around Wicken Bonhunt, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- White, clear, grey or coloured to suit, where the product allows
- Domestic, commercial and hotel work
- Approved under the ARBOMaster scheme
- A sealant colour to suit the surroundings
What we cannot put right
In fairness, there are a few things sealant will not fix:
- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on

How it works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Wicken Bonhunt, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Related advice
Wicken Bonhunt buildings and the weather
Historic houses like Audley End House (about 3.7 miles north-east) are a reminder that the area around Wicken Bonhunt has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Joyce Frankland Academy, larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of St Margaret include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Newport (Essex) station, outside joints that have cracked can let damp into a rental, so check them between lets.

Aftercare tips
So the new joints stay in good condition:
- Avoid pressure-washing directly into sealant joints
- Fix overflowing gutters above sealed joints
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
