External mastic in Saltdean, done properly
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 rarely last long. We take the old material out and do it properly. We work on joints between brick and frames, concrete & block and copings & trims, and common reasons people get in touch are water getting into walls through failed joints and movement joints with cracked, split or missing sealant.
Outbuildings, garages and conservatories around homes in places like Saltdean add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Your job is guaranteed for a year, as with all our work.

Common problems we fix in Saltdean
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
These are the problems we’re asked about most:
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
Schools such as Saltdean Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions from Saltdean
Can you help a landlord with a rental near Southease station?
Yes. We work for letting agents and landlords as well as householders. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Does living near the coast affect external mastic in Saltdean?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Are you fully insured?
Yes. Full insurance covers our work.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

External mastic in Saltdean: local notes
Saltdean is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Monk's House (about 3.5 miles north-east) nearby, there’s older building stock in the area around Saltdean 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 landlords with property near Southease station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. A visit to Saltdean is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height

Related advice
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before sealing.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
