About our external mastic in South Gorley
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. If you have moss and dirt in joints with no sealant left and movement joints with cracked, split or missing sealant, we can put it right, on joints between brick and frames, concrete & block and façade panels alike.
Around South Gorley, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in South Gorley
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Look out for any of the following:
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
If you live in an older home near Church of the Holy Ascension, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from South Gorley
Do you cover smaller places like South Gorley?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do external mastic in South Gorley?
Yes. Our work covers London and the South East, and South Gorley is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
Are you insured?
Yes. We’re fully insured.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Act on the first splits you see
- Point out the joints to other trades
- Make sure movement joints aren’t pointed over
- Keep high-pressure jets off the joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as South Gorley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Related advice
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like South Gorley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What external mastic looks like in South Gorley
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Hyde Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
