External mastic for homes and businesses in Highclere
On houses, flats and commercial buildings across Highclere, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for gaps where render, brick and frames meet and weathered mastic that no longer stretches, across concrete & block, render & cladding joints and joints between brick and frames.
Somewhere as small as Highclere, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a one-year guarantee.

Landlord and commercial work in Highclere
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We also work for property managers and facilities teams. Several sites can go on one quote, and we are fully insured for the work.
Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Copings & trims

Outside joints around Highclere
Historic houses like Highclere Castle (about 1.4 miles south-east) are a reminder that the area around Highclere has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Woolton Hill Junior School? Then its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Church of St Michael Archangel, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What happens if it’s left?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Highclere, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What else we do in Highclere
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Wash walls gently around the sealant
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we have said otherwise
- Check external joints each spring
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
How it works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on the building. Somewhere like Highclere needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Advice
What affects the quote in Highclere
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- The type of sealant required
- Whether there’s mould to deal with
- Working hours on commercial sites
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
To make quoting easier, let us know:
- Where the property is
- Access, such as stairs, a lift or height
- Whether it has been sealed before
- The problem you’ve noticed
To get a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
Common problems we fix in Highclere
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
It’s worth asking for a quote if you see:
- Weeds or debris growing in open joints
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
If you let a flat or house near Newbury station, outside joints that have cracked can let damp into a rental, so check them between lets.

Common questions in Highclere
Do you cover Highclere for external mastic?
Yes, Highclere is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Newbury station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We will reseal it with a flexible sealant.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
