How we handle external mastic in Broomfield
For buildings in Broomfield, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have old sealant gone brittle and cracked and weeds or debris growing in open joints, we can help, on concrete & block, joints between brick and frames and copings & trims alike.
Outside joints can only be sealed when they’re dry, so work in Broomfield is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Walls and rooflines in Broomfield
Broomfield is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Herne Church of England Infant School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Herne Bay station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Church of St Bartholomew, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Broomfield is about 1 mile south-east of Herne Bay, in Kent.

Different surfaces, different methods
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Send us any details you have about the façade.
What we do, step by step
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Somewhere as small as Broomfield, access is often the only tricky part. 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Keep children and pets away from the work area
- Clear the area around the work
- Mention any tricky access

Common questions in Broomfield
Will you come out to Broomfield?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is external mastic in a coastal place like Broomfield any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
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.
Can landlords and businesses book you?
Yes, often. We can quote for several properties at once.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.

What else we do in Broomfield
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Render that is blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Façade panels
Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Around Broomfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why us?
- A sealant colour to suit the surroundings
- We are fully insured
- Colour agreed with you before we start
- More than 20 years in sealant work
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
How we quote for external mastic
For a quick quote, just ask. What matters most is:
- How many areas need sealing
- Which sealant suits the joint
- How easy the joints are to reach
- Any mould that needs treating
What it costs 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.
What we need to know
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- If someone has resealed it before
- Where the property is
