About our external mastic in Poulner
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on brickwork movement joints, concrete & block and copings & trims, and the jobs we see most are joints pointed up with cement by mistake and moss and dirt in joints with no sealant left.
In a smaller place like Poulner, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Your questions about external mastic in Poulner
Is external mastic in Poulner guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Poulner within the area you cover?
Yes, Poulner is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.
Landlord and commercial work in Poulner
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Why it’s worth doing now in Poulner
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Poulner, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work generally takes a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Poulner, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Walls and rooflines in Poulner
With historic houses such as Avon Tyrrell House (about 3.8 miles south) nearby, there’s older building stock in the area around Poulner 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.
If you live in an older home near St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Signs you need external mastic in Poulner
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
Most people get in touch after spotting something like this:
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
Schools such as Poulner Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one.
What we cannot put right
Before booking, it’s worth knowing the limits:
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
- Movement that is more than a sealant joint can take
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.
What we seal
- Brickwork movement joints
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
- Concrete & block
- Façade panels
Keeping the joints in good condition
Looking after new joints is easy:
- Make sure movement joints aren’t pointed over
- Keep high-pressure jets off the joints
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
