External Mastic in Bradenham
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Bradenham and across Buckinghamshire. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
- Sealant that has lost its bond to the brick or render
Why deal with it now?
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 pays to do it properly once. Older cottages and farmhouses around Bradenham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
What you get with us
- More than 20 years in sealant work
- A 12-month guarantee on all work

- Sealant colour chosen to suit

About our external mastic in Bradenham
For buildings in Bradenham, 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. We work on brickwork movement joints, joints between brick and frames and copings & trims, and the jobs we see most are moss and dirt in joints with no sealant left and rigid filler in a joint that should flex.
Around Bradenham, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
All of our work is guaranteed for twelve months.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Bradenham, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

What external mastic looks like in Bradenham
Historic houses like West Wycombe Park House (about 1.8 miles south) are a reminder that the area around Bradenham has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, 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 Church of St Botolph, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Saunderton station, outside joints that have cracked can let damp into a rental, so check them between lets.

Signs you need external mastic in Bradenham
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Look out for any of the following:
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
- Cracked joints where brick meets render or frames
If you look after a building such as Naphill and Walters Ash School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
- How much experience the applicator has
- The length of the guarantee
What sealant work can’t fix
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Façade panels

Do you cover Bradenham for external mastic?

How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.

What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Different surfaces, different methods
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
What affects the quote in Bradenham
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- The product the joint needs
- The size of the job
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Helping us quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- The rough size of the job
- Whether it has been sealed before
- The problem you’ve noticed
