External Mastic in Bighton
We cover Bighton for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Weathered mastic that no longer stretches
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
Can I do it myself?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
About our external mastic in Bighton
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We are often asked to deal with joints pointed up with cement by mistake and brick movement joints where the sealant has split, across copings & trims, render & cladding joints and concrete & block.
Outside joints can only be sealed when they’re dry, so work in Bighton is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All our work comes with our one-year guarantee, wherever you are in Hampshire.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Somewhere like Bighton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- 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
- Tell us about any water getting in
- Mention any tricky access
- Keep pets and children clear of the area while we work

What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Outside joints around Bighton
With historic houses such as Hinton Ampner House (about 4.3 miles south) nearby, there’s older building stock in the area around Bighton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For site and facilities teams at buildings such as Perins School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Quotes for external mastic in Bighton
There’s no set price list, because jobs vary so much. What we look at:
- How many areas need sealing
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The type of sealant required
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What we need to know
There’s no need for technical detail. Just tell us:
- How we’d reach the joints
- If someone has resealed it before
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
For external mastic in Bighton, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
What happens if it’s left?
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Around Bighton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear quote before any work starts.

Bighton questions
Do you cover smaller places like Bighton?
Yes, Bighton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is external mastic in Bighton guaranteed?
All our work, in Bighton and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
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. There’s a wide choice of exterior colours.
How long does external mastic take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we will say how long yours will take.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Loose or hollow render, which needs re-rendering
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Render & cladding joints

When to call us in Bighton
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
The problems people normally mention when they call include:
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
In the older streets around Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.
