External mastic in Hollington
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. We work on joints between brick and frames, render & cladding joints and concrete & block, and people most often call us about gaps where render, brick and frames meet and joints pointed up with cement by mistake.
External sealant needs dry, clean surfaces, so work around Hollington is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Hollington, 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 start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Hollington buildings and the weather
Historic houses like Stargroves (about 0.8 miles north-west) are a reminder that the area around Hollington has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For landlords with property near Kintbury station, outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like St Thomas' Church of England Infant School? Then larger buildings have long runs of movement joint that eventually need resealing.

What’s near Hollington
Hollington’s nearest station is Kintbury station, roughly 4.9 miles north-west. Well-known places in the area include Newbury Castle (4.2 miles north). Not far away are Kintbury Newt Ponds and Pilot Hill.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Avoid pressure-washing directly into sealant joints
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Have failed joints looked at early
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Why it’s worth doing now in Hollington
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. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Hollington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

What affects the quote in Hollington
We do not publish a price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- How many areas need sealing
- When we can work, for business premises
- The amount of work
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Roughly how big the job is
- The address or postcode of the job
- The problem you’ve noticed
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
When something else is needed
It helps to know what we cannot do too:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that isn’t coming from the joint
- Movement that’s more than a sealant joint can take
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
Where we work in Hollington
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Façade panels
- Render & cladding joints
How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Common problems we fix in Hollington
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
These are the problems we’re asked about most:
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
In the older streets around Church of St Thomas, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What to look for in a quote
- What product goes in the joint
- What happens if they find a problem under the old sealant
- Whether VAT is included
- Whether all the old sealant comes out first
