External Mastic in Shipley
We cover Shipley for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Water getting into walls through failed joints
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Shipley needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints

Related advice
External mastic in Shipley, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. Common call-outs are for brick movement joints where the sealant has split and plants rooting in failed movement joints, across concrete & block, copings & trims and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Shipley is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Have failed joints looked at early
- Point out the joints to other trades
- Leave the joints unpainted unless we’ve said otherwise
- Fix overflowing gutters above sealed joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Common questions in Shipley
Do you cover smaller places like Shipley?
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.
Do you cover Shipley for external mastic?
Yes. We work across London and the South East, and Shipley is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
How do I get a quote for external mastic in Shipley?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
How long does external mastic take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We’ll confirm how long when we quote.
Common problems we fix in Shipley
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
- Joints with sealant missing in places
Homes close to The Church of St Mary the Virgin include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Failed render or damaged cladding panels
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Façade panels
How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so the movement is taken up.
Walls and rooflines in Shipley
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Shipley CofE Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Billingshurst station, outside joints that have cracked can let damp into a rental, so check them between lets.
