High Easter External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in High Easter. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Leaking joints around cladding and façade panels
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like High Easter, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why choose Mr Mastic in High Easter
- Quality sealants from Arbo and Everbuild
- You choose the colour before work begins

About our external mastic in High Easter
On houses, flats and commercial buildings across High Easter, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you are dealing with failed sealant between panels on a façade and old sealant gone brittle and cracked, we can put it right, whatever the surface.
Older homes in small places like High Easter may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
All our work comes with our one-year guarantee.

How we quote for external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The number of rooms or windows
- Access and height
- How much there is to do
- Any mould that needs treating
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
To make quoting easier, please include:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Your questions about external mastic in High Easter
Is there a guarantee on external mastic in High Easter?
All our work, in High Easter and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like High Easter?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
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. If it does not work out, we can redo it.
How much does external mastic cost in High Easter?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint does not draw the eye.
How long does the job take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including preparation and clearing up. Your quote will say how long we expect yours to take.
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like High Easter, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

What external mastic looks like in High Easter
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.
In and around High Easter, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What’s near High Easter
We work in homes and buildings around Cock And Bell pub, among other places. Other landmarks nearby include Willingale Doe (4.5 miles south-west) and Broomfield Hospital (5.1 miles south-east).
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep soil, plants and ivy away from the joints
- Leave the joints unpainted unless we have said otherwise
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Common problems we fix in High Easter
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
It’s worth asking for a quote if you see:
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Joints where the bead has come unstuck
If you live in an older home near Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- Who turns up on the day
- What insurance they hold
