External Mastic in Inkpen
We cover Inkpen for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
- Joints with sealant missing in places
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Look over the joints every year, ideally after winter
- Keep water from gutters off the wall
- Keep soil, plants and ivy away from the joints
- Have failed joints looked at early
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
How we handle external mastic in Inkpen
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 where a rigid filler would soon crack. We work on joints between brick and frames, façade panels and copings & trims, and the jobs we see most are movement joints with cracked, split or missing sealant and old sealant gone brittle and cracked.
Older homes in small places like Inkpen may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Inkpen: your questions answered
Can you help a landlord with a rental near Kintbury station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Will you come out to Inkpen?
Yes, Inkpen is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How much does external mastic cost in Inkpen?
There’s no set price, as it 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 any work starts.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Movement that’s more than a sealant joint can take
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Façade panels
- Concrete & block
- Render & cladding joints
When to call us in Inkpen
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
People usually contact us after spotting something like this:
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
For landlords with property near Kintbury station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before booking
- Whether you can choose the colour
- What happens if the job turns out different
- What preparation is included
- What product goes in the joint
Why act early in Inkpen
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. In a small place like Inkpen, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Inkpen buildings and the weather
With historic houses such as Stargroves (about 3.2 miles south-east) nearby, there’s older building stock in the area around Inkpen 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Inkpen Primary School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of St Michael, an extension built onto an older house moves differently, and the joint between them takes the strain.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. In a small place like Inkpen, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
