External & façade joints in Norton, West Sussex
Movement joints in Norton need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

- Panel joints letting water in
- Gaps where render, brick and frames meet
External mastic in Norton, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you are dealing with rigid filler in a joint that should flex and sealant pulling away from one side of the joint, we can put it right.
Older homes in small places like Norton may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about external mastic in Norton
Is Norton in your area for external mastic?
Yes. Our work covers London and the South East, and Norton is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
I let a flat near Barnham station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
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, while a short indoor joint may be within reach.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

Walls and rooflines in Norton
With historic houses such as Goodwood House (about 2.9 miles north-west) nearby, there’s older building stock in the area around Norton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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 The Parish Church of St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Barnham station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Ormiston Six Villages Academy, larger buildings have long runs of movement joint that eventually need resealing.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What the job involves on each surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and protects the render itself.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Copings & trims
- Façade panels
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Norton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. Somewhere as small as Norton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- 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.
Before we arrive
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
