External & façade joints in Hunton, Kent
We cover Hunton for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
How we handle external mastic in Hunton
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. We work on copings & trims, façade panels and render & cladding joints, and the jobs we see most are damp patches traced to an open external joint and joints where the bead has come unstuck.
In a village or hamlet like Hunton, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Hunton questions
Is Hunton within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Yalding station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Are you fully insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
When to call us in Hunton
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we’re asked about most:
- Joints pointed up with cement by mistake
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Hard, crazed mastic that has stopped moving
If you live in an older home near St Mary's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Before you book anyone
- How the colour is chosen
- What preparation is included
- How hidden problems are handled
- Whether they seal over old material or remove it
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
- Movement that’s more than a sealant joint can take
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- Access and height
- The type of sealant required
- How many rooms, windows or areas are involved
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.
Asking for a quote
What to tell us when you ask for a quote:
- Roughly how big the job is
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- Where the property is
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.
DIY versus a professional finish
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why it’s worth doing now in Hunton
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Hunton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours to a few days, depending on the length of joint and the access. In a small place like Hunton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Mention any sign-in or site rules at work premises
