Do you need external mastic in West Itchenor?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Signs it’s time to call us include:
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
If you live in an older home near St Nicholas' Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic in West Itchenor: local notes
West Itchenor is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
Rented homes near Bosham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Avoid pressure-washing directly into sealant joints
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we’ve said otherwise
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Landlord and commercial work in West Itchenor
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
For anyone letting property in or around West Itchenor, several properties can be quoted together. Send us the addresses and the work at each.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
FAQs for West Itchenor
Can you help a landlord with a rental near Bosham station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like West Itchenor?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is the work guaranteed?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Why act early in West Itchenor
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around West Itchenor can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

The process
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the building in most cases. Somewhere as small as West Itchenor, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
