External & façade joints in Greenham, West Berkshire
Movement joints in Greenham need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.

External mastic for homes and businesses in Greenham
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. We are often asked to deal with rigid filler in a joint that should flex and weathered mastic that no longer stretches, on copings & trims, concrete & block and render & cladding joints.
In a village or hamlet like Greenham, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the cost of external mastic
There’s no set price list, because jobs vary so much. What we look at:
- How easy the joints are to reach
- Any working-time requirements on site
- Any mould that needs treating
- How many rooms, windows or areas are involved
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

To help us quote quickly, let us know:

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Act on the first splits you see
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
- Keep soil, plants and ivy away from the joints
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Questions from Greenham
Can you help a landlord with a rental near Newbury Racecourse station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Will you come out to Greenham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long will you be here?
That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on the building. We’ll tell you when we quote.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint does not draw the eye.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you work at height?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Landlord and commercial work in Greenham
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Around Greenham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Adding movement joints to masonry that has none
- Damp that isn’t coming from the joint
- Render that is blown, hollow or coming away
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Copings & trims
- Joints between brick and frames

Walls and rooflines in Greenham
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. With historic houses such as Shaw House (about 1.9 miles north) nearby, there’s older building stock in the area around Greenham as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as The Willows Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Newbury Racecourse station, split movement joints are easy to miss on a rental until damp shows inside.
