How we handle external mastic in Tunstall
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you have water getting into walls through failed joints and sealant that has lost its bond to the brick or render, we can put it right.
Around Tunstall, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
When to call us in Tunstall
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The problems people normally mention when they call include:
- Brick movement joints where the sealant has split
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
- Old sealant gone brittle and cracked
For an older house near a landmark such as Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Outside joints around Tunstall
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.
For landlords with property near Sittingbourne station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Tunstall Church of England (Aided) Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Should I try it myself first?
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Tunstall can have timber floors and frames, where water from a failed joint can cause rot 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. We take all of that into account in your quote.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.

What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
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 will confirm the access.

What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
