External mastic in Alverstone Garden Village, done properly
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on façade panels, joints between brick and frames and concrete & block, and common reasons people get in touch are water getting into walls through failed joints and plants rooting in failed movement joints.
In a village or hamlet like Alverstone Garden Village, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee, large or small.

Landlord and commercial work in Alverstone Garden Village
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
How we quote for external mastic
Call for a quick quote. The main things that affect it are:
- Any mould that needs treating
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- How many areas need sealing
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Helping us quote
Photos help, but a description is a good start. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Where the property is
- Roughly how big the job is
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand.
Keeping the joints in good condition
So the new joints stay in good condition:
- Point out the joints to other trades
- Walk round the building once a year and look at the joints
- Act on the first splits you see
- Never let anyone fill a movement joint with mortar
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Alverstone Garden Village questions
Does the coastal weather in Alverstone Garden Village affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Sandown station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
How long does external mastic take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
External mastic in Alverstone Garden Village: local notes
Alverstone Garden Village is close to 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as All Saints' Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Sandown station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Newchurch Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What else we do in Alverstone Garden Village
How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. For a village or hamlet like Alverstone Garden Village, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints

Advice
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
- Cracks in the bricks or render themselves, away from the joints
