Signs you need external mastic in Ashingdon
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
If you can see any of these, it’s time to have the joints looked at:
- Failed seals between different materials
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
For landlords with property near Hockley station, outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- Is the old sealant removed completely?
- Whether they’re fully insured
- Which colour the sealant will be
- What preparation is included
External mastic for homes and businesses in Ashingdon
For buildings in Ashingdon, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on render & cladding joints, copings & trims and concrete & block, and people most often call us about damp patches traced to an open external joint and joints where the bead has come unstuck.
In and around Ashingdon, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Outside joints around Ashingdon
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Southchurch Hall (about 4.9 miles south) nearby, there’s older building stock in the area around Ashingdon 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.
For site and facilities teams at buildings such as King Edmund School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St Andrew, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. In a smaller place like Ashingdon, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Landlord and commercial work in Ashingdon
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, 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.
What the job involves on each surface
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 where it can be done safely.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
Can I do it myself?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How we quote for external mastic
Call for a quick quote. The main things that affect it are:
- Whether there’s mould to deal with
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Whether the work is at height
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
Helping us quote
To make quoting easier, let us know:
- A few pictures by email, if you can
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
When it is not the sealant
We will not take on work that will not last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that’s more than a sealant joint can take
- Walls that need new movement joints cut into them
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
