External mastic in Sherfield on Loddon
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on render & cladding joints, brickwork movement joints and concrete & block, and common reasons people get in touch are sealant that has lost its bond to the brick or render and gaps where render, brick and frames meet.
Older homes in small places like Sherfield on Loddon may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
You get a 12-month guarantee, the same in Sherfield on Loddon as everywhere else we work.

When it is not the sealant
In fairness, there are a few things sealant won’t fix:
- Subsidence or other structural problems
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints

What else we do in Sherfield on Loddon
Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
The process
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. The work normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Sherfield on Loddon needs a little journey planning: 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.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Clear the area around the work
- Let us know about parking restrictions
- Tell us about any water getting in

Outside joints around Sherfield on Loddon
Historic houses like Stratfield Saye House (about 2.6 miles north-east) are a reminder that the area around Sherfield on Loddon has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Bramley (Hants) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Sherfield School, larger buildings have long runs of movement joint that eventually need resealing.

How long will you be here?

Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

What we’re called out for in Sherfield on Loddon
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The problems people usually mention when they call include:
- Movement joints filled with mortar instead of sealant
- Cracked joints where brick meets render or frames
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
If you live in an older home near Church of St. Leonard, older walls, gutters and the joints where extensions meet them need a flexible sealant.

- Working hours on commercial sites
- The product the joint needs
- How easy the joints are to reach

What to tell us for a quote
When you contact us, it’s useful to know:
- Whether it’s a home or a business
- What’s wrong with the joints now
- Where the property is
- Access, such as stairs, a lift or height
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
