Questions from Shelvin
Can you do external mastic in Shelvin?

Do you work for landlords with property near Shepherds Well station?

Where are you based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
About our external mastic in Shelvin
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. Common call-outs are for moss and dirt in joints with no sealant left and sealant that has lost its bond to the brick or render, on façade panels, concrete & block and copings & trims.
Somewhere as small as Shelvin, 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.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Shelvin can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What we cannot put right
In fairness, there are a few things sealant will not fix:
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep movement joints as flexible joints, not mortar
- Avoid pressure-washing directly into sealant joints
- Keep soil, plants and ivy away from the joints
- Tell anyone working on the walls about the movement joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Surface by surface
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.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
Outside joints around Shelvin
Historic houses like Acrise Place (about 4 miles south-west) are a reminder that the area around Shelvin has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Homes close to Church of St Martin include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Shepherds Well station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Shelvin, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
