- Sealant pulling away from one side of the joint
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
Keeping the joints in good condition
Looking after new joints is easy:
- Check external joints each spring
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
External mastic for homes and businesses in Walton Hall
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on render & cladding joints, joints between brick and frames and concrete & block, and common reasons people get in touch are sealant pulling away from one side of the joint and moss and dirt in joints with no sealant left.
Older homes in small places like Walton Hall may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Different surfaces, different methods
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Signs you need external mastic in Walton Hall
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
Keep an eye out for any of the following:
- Movement joints filled with mortar instead of sealant
- Panel joints letting water in
- Old sealant gone brittle and cracked
- Moss and dirt in joints with no sealant left
Schools such as Kents Hill School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- Is VAT in the price?
- Is the old sealant removed completely?
- What happens if the job turns out different
- Whether the sealant suits the joint
Honest limits
We will always be straight with you, so here’s what sealant can’t fix:
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

External mastic in Walton Hall: local notes
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. With historic houses such as Bletchley Park (about 2.3 miles south-west) nearby, there’s older building stock in the area around Walton Hall as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Church of St Thomas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Bow Brickhill station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Advice
Walton Hall questions
Will you come out to Walton Hall?
Yes, Walton Hall is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Bow Brickhill station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
