External mastic in Mockbeggar
On houses, flats and commercial buildings across Mockbeggar, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on brickwork movement joints, copings & trims and joints between brick and frames, and common reasons people get in touch are brick movement joints where the sealant has split and weathered mastic that no longer stretches.
Somewhere as small as Mockbeggar, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

When to call us in Mockbeggar
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Weeds or debris growing in open joints
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
- Rigid filler in a joint that should flex
If you look after a building such as Cliffe Woods Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Mockbeggar, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

External mastic in Mockbeggar: local notes
Mockbeggar is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Temple Manor, about 2.3 miles south, is one of the historic houses in the wider area around Mockbeggar. If you let a flat or house near Higham station, outside joints that have cracked can let damp into a rental, so check them between lets.
Mockbeggar is about 2 miles north of Rochester, in Medway. Anywhere in ME3, our applicators can take on external mastic. Mockbeggar is one of 68 towns and villages in Medway we cover for external mastic. You can also see our page for Chelmsford, roughly 22 miles from Mockbeggar.

How we quote for external mastic
Call for a quick quote. What matters most is:
- The size of the job
- Which sealant suits the joint
- Mould in or behind the old joints
- When we can work, for business premises
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- The address or postcode of the job
- Any previous sealing or DIY work
- A few pictures by email, if you can
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.
What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
- Act on the first splits you see
- Keep movement joints as flexible joints, not mortar
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.

What sealant work cannot fix
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:
- Movement that is more than a sealant joint can take
- Render that is blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.

Questions from Mockbeggar
Does living near the coast affect external mastic in Mockbeggar?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Mockbeggar?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
How do you reach high-level joints?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
What should I tell you?
Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
