The process
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. In a small place like Five Ash Down, 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.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Clear the area around the work

External mastic in Five Ash Down, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you’re dealing with cracked joints where brick meets render or frames and joints with sealant missing in places, we can put it right.

Why it’s worth doing now in Five Ash Down
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Five Ash Down, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why us?
- Neat joints and a tidy finish
- Fully insured
- ARBOMaster approved applicator

Five Ash Down questions
Do you cover smaller places like Five Ash Down?
Yes, Five Ash Down is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Buxted station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
When will the joints need doing again?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What we cannot put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Outside joints around Five Ash Down
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.
For site and facilities teams at buildings such as Buxted CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Buxted station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When to call us in Five Ash Down
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Most people get in touch after spotting one of these:
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
- Movement joints filled with mortar instead of sealant
For an older house near a landmark such as Five Ash Down Independent Chapel, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
