External & façade joints in Hawkenbury, Kent
Problem with your movement joints in Hawkenbury? We cut out the old, prepare the joints and apply the right sealant.
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
About our external mastic in Hawkenbury
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Common call-outs are for weeds or debris growing in open joints and gaps where render, brick and frames meet, across joints between brick and frames, copings & trims and render & cladding joints.
Around Hawkenbury, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Signs you need external mastic in Hawkenbury
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
People usually contact us after spotting one of these:
- Rigid filler in a joint that should flex
- Panel joints letting water in
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
Letting a property close to Tunbridge Wells station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- The length of the guarantee
- What product goes in the joint
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
What external mastic looks like in Hawkenbury
Historic houses like Groombridge Place (about 3.9 miles west) are a reminder that the area around Hawkenbury has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near St Peter's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Claremont Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Hawkenbury questions
Will you come out to Hawkenbury?
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.
Do you cover Hawkenbury for external mastic?
Yes. Our work covers London and the South East, and Hawkenbury is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Can landlords and businesses book you?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What is backing rod for?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the 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.
Quotes for external mastic in Hawkenbury
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- The size of the job
- The type of sealant required
- Working hours on commercial sites
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Helping us quote
There’s no need for technical detail. Just tell us:
- Where the job is, and your postcode
- The rough size of the job
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. In a smaller place like Hawkenbury, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
