What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
How long does the job take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
How much does external mastic cost in Rout's Green?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
External mastic for homes and businesses in Rout's Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you have leaking joints around cladding and façade panels and plants rooting in failed movement joints, we can put it right, on copings & trims, render & cladding joints and brickwork movement joints alike.
In a village or hamlet like Rout's Green, older cottages and farm buildings often stand in the open, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Somewhere as small as Rout's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

How we quote for external mastic
We quote each job individually. These are the things that affect it:

- The number and length of the joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

There’s no need for technical detail. Just tell us:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep high-pressure jets off the joints
- Make sure movement joints aren’t pointed over
- Act on the first splits you see
- Tell anyone working on the walls about the movement joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
Outside joints around Rout's Green
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like West Wycombe Park House (about 3.6 miles south-east) are a reminder that the area around Rout's Green 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.
For an older house near a landmark such as Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Bledlow Ridge School, its movement joints, gutters and trims need looking after like any other building’s.

Common problems we fix in Rout's Green
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Common reasons people contact us are:
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
Rented homes near Saunderton station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Surface by surface
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
