External mastic in Iford
For buildings in Iford, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on render & cladding joints, joints between brick and frames and brickwork movement joints, and the jobs we see most are water getting into walls through failed joints and rigid filler in a joint that should flex.
Outside joints can only be sealed when they’re dry, so work in Iford is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

FAQs for Iford
Do you cover smaller places like Iford?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Lewes station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
How long does external mastic take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we will tell you how long to expect.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.
How much does external mastic cost in Iford?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
When to call us in Iford
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for any of the following:
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
For an older house near a landmark such as St Pancras Church (Kingston near Lewes), old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
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.
How the job changes by surface
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.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Have failed joints looked at early
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
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.
What external mastic looks like in Iford
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Monk's House (about 1.4 miles south-east) are a reminder that the area around Iford has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Iford and Kingston Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Lewes station, split movement joints are easy to miss on a rental until damp shows inside.

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation from start to finish. For a village or hamlet like Iford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Mention any parking rules near the property
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Advice
Why act early in Iford
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Iford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before work begins.
