External mastic in Lee Common
For buildings in Lee Common, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you’re dealing with panel joints letting water in and sealant pulling away from one side of the joint, we can help.
Around Lee Common, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
Big or small, it’s backed by our one-year guarantee.

Lee Common buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Cholesbury Manor House (about 2.3 miles north-east) are a reminder that the area around Lee Common 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.
Schools such as Lee Common Church of England School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as St Mary's, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Lee Common is about 3 miles west of Chesham, in Buckinghamshire. Wherever you are in the HP16 postcode area, we cover external mastic for homes and businesses. Our Buckinghamshire coverage runs to 263 places, Lee Common among them. There’s also a page for Reading, about 23 miles away.

Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together. Older cottages and farmhouses around Lee Common can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job usually takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Somewhere like Lee Common 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.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any parking rules near the property
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Look over the joints every year, ideally after winter
- Don’t let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.

Common questions in Lee Common
Do you cover smaller places like Lee Common?
Yes. Lee Common is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Great Missenden station. Can you help?
Yes, rental work is part of what we do. You can phone 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 hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
When it is not the sealant
It helps to know what we can’t do too:
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Common problems we fix in Lee Common
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, and it tears off the sides.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
- Sealant pulling away from one side of the joint
- Panel joints letting water in
If you let a flat or house near Great Missenden station, outside joints that have cracked can let damp into a rental, so check them between lets.
