About our external mastic in Goose Green
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. Common call-outs are for failed sealant between panels on a façade and movement joints filled with mortar instead of sealant, on joints between brick and frames, concrete & block and copings & trims.
In a village or hamlet like Goose Green, older cottages and farm buildings often stand in the open, 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.
Our work is backed for twelve months.

The process
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the building in most cases. Somewhere like Goose Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us if parking is tricky
- Clear the area around the work
- Let us know about earlier repairs to the joints

How to look after the new joints
So the new joints stay in good condition:
- Check external joints each spring
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
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.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.

External mastic in Goose Green: local notes
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.
If you let a flat or house near Broxbourne station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Westfield Community Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Why it’s worth doing now in Goose Green
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. Older cottages and farmhouses around Goose Green can have timber 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, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What the job involves on each surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one before sealing.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
- Failed render or damaged cladding panels
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Render & cladding joints
- Copings & trims

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
