External mastic in Langley Heath
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on render & cladding joints, concrete & block and façade panels, and common reasons people get in touch are moss and dirt in joints with no sealant left and rain getting behind render or cladding at a joint.
Around Langley Heath, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
A 12-month guarantee comes as standard.

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Langley Heath needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

Langley Heath questions
Do you cover Langley Heath for external mastic?
Yes, Langley Heath is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Will you come out to Langley Heath?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can new sealant go over the old?
No. The old sealant always comes out first.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Different surfaces, different methods
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Langley Heath buildings and the weather
With historic houses such as Stoneacre (about 1.4 miles north-west) nearby, there’s older building stock in the area around Langley Heath 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Hollingbourne station, split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Do you need external mastic in Langley Heath?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Look out for any of the following:
- Failed sealant between panels on a façade
- Cracked joints where brick meets render or frames
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
Schools such as Senacre Technology College are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Why it’s worth doing now in Langley Heath
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Older cottages and farmhouses around Langley Heath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
