About our external mastic in Mockbeggar
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you have sealant pulling away from one side of the joint and weeds or debris growing in open joints, we can help, whatever the surface.
Somewhere as small as Mockbeggar, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, it’s backed by our one-year guarantee in Mockbeggar and across Hampshire.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. For a village or hamlet like Mockbeggar, 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.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

Mockbeggar: your questions answered
Can you do external mastic in Mockbeggar?
Yes, Mockbeggar is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Is Mockbeggar within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long does external mastic take?
That depends on the amount of work, but most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll give you a better idea when we quote.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Where are you based?
We work from Crawley. Our applicators cover Mockbeggar, along with the rest of our area.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Surface 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.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Mockbeggar can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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 the work is at height. We take all of that into account in your quote.

What external mastic looks like in Mockbeggar
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Mockbeggar, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. If you live in an older home near Church of St Martins, an extension built onto an older house moves differently, and the joint between them takes the strain.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Leave the joints unpainted unless we have said otherwise
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
- Clear growth from the base of walls and joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
