Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Little Atherfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

External mastic in Little Atherfield
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Typical jobs include sealant pulling away from one side of the joint and joints with sealant missing in places, across concrete & block, joints between brick and frames and brickwork movement joints.
Somewhere as small as Little Atherfield, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Your job is guaranteed for a year, as with all our work.

For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Letting agents and landlords in Little Atherfield can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Little Atherfield, 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 inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Mention any tricky access

What we are called out for in Little Atherfield
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
- Old sealant gone brittle and cracked
Wolverton Manor, about 1.6 miles north, is one of the historic houses in the wider area around Little Atherfield, and older homes nearby need a sealant that suits their walls.
Before booking anyone
- Who turns up on the day
- How hidden problems are handled
- When the joint can take water or movement
- How long the guarantee is
How to look after the new joints
To keep the joints looking good and working properly:
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
How the job changes by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Walls and rooflines in Little Atherfield
Little Atherfield 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
