Toddington External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Toddington. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
External mastic in Toddington
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on render & cladding joints, copings & trims and brickwork movement joints, and the jobs we see most are joints pointed up with cement by mistake and moss and dirt in joints with no sealant left.
Homes around Toddington range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Toddington buildings and the weather
Toddington is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Lyminster Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Littlehampton station, split movement joints are easy to miss on a rental until damp shows inside.
Toddington is about 1 mile north of Littlehampton, in West Sussex. For external mastic in and around Toddington, please call 0345 464 0079 or send us an email for a quick quote.

Toddington’s nearest station is Littlehampton station, roughly 1.1 miles south-west of the centre.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
- Point out the joints to other trades
- Keep movement joints as flexible joints, not mortar
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Loose or hollow render, which needs re-rendering
- Damp that isn’t coming from the joint
- Walls that need new movement joints cut into them
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Render & cladding joints
- Copings & trims
- Concrete & block
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
Different surfaces, different methods
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.

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 pays to do it properly once. Around Toddington, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- 20+ years of sealant experience

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the building. For a job in Toddington, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules

Advice
Do you need external mastic in Toddington?
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The most common problems we see are:
- Failed seals between different materials
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
In the older streets around All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common questions in Toddington
Is external mastic in a coastal place like Toddington any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Littlehampton station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
