How the visit works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before we start. The work normally takes a few hours for a handful of joints, longer for a whole elevation. A visit to Wick is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Advice
External mastic for homes and businesses in Wick
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. If you have failed seals between different materials and weathered mastic that no longer stretches, we can help, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Wick 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.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

How we quote for external mastic
There’s no set price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- When we can work, for business premises
- Which sealant suits the joint
- How many areas need sealing
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
Helping us quote
There’s no need for technical detail. Just tell us:
- Whether it has been sealed before
- Where the job is, and your postcode
- The rough size of the job
- What’s wrong with the joints now
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or drop us an email with the details.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Make sure movement joints are not pointed over
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
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 it’s worth resealing at the first signs.
FAQs for Wick
Is Wick within the area you cover?
Yes. Wick is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is external mastic in a coastal place like Wick any different?
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.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Leave it or put it right?
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Wick, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Outside joints around Wick
Wick is within about 2 miles 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant. Schools such as Lyminster Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Littlehampton station, outside joints that have cracked can let damp into a rental, so check them between lets.

Surface by surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
