About our external mastic in Wingham
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it. If you’re dealing with sealant that has lost its bond to the brick or render and rain getting behind render or cladding at a joint, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Wingham 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 isn’t right with it in that time, tell us and we will put it right.

Surface by surface
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Walk round the building once a year and look at the joints
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. Older cottages and farmhouses around Wingham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. For a village or hamlet like Wingham, 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 inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed

What else we do in Wingham
What external mastic looks like in Wingham
With historic houses such as Goodnestone Park (about 2 miles south) nearby, there’s older building stock in the area around Wingham as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Letting a property close to Adisham station? Then split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as St Mary's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need external mastic in Wingham?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
It’s worth asking for a quote if you see:
- Gaps where render, brick and frames meet
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
Schools such as Wingham Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

FAQs for Wingham
Do you work for landlords with property near Adisham station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Will you come out to Wingham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. We will reseal it with a flexible sealant.
How long does the job take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. We’ll confirm how long when we quote.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
