External mastic in Buckland
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on brickwork movement joints, façade panels and concrete & block, and the jobs we see most are joints with sealant missing in places and failed seals between different materials.
In a village or hamlet like Buckland, 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.

Walls and rooflines in Buckland
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.
For an older house near a landmark such as St Andrew's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Freman College? Then its movement joints, gutters and trims need looking after like any other building’s.

Signs you need external mastic in Buckland
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Signs it’s time to call us include:
- Joints with sealant missing in places
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
Rented homes near Royston station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book

How do I get a quote for external mastic in Buckland?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us with a short description of the job.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
How do you reach high-level joints?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
When something else is needed
New sealant cannot fix everything, and we will tell you before work begins. It won’t solve:
- Cracked brickwork or render that needs a builder or plasterer
- Movement that’s more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

What else we do in Buckland
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the building. In a small place like Buckland, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

Related advice
Why it’s worth doing now in Buckland
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Buckland, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

How we quote for external mastic
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- Mould in or behind the old joints
- Working hours on commercial sites
- The size of the job
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- How we’d reach the joints
- Where the property is
Need a quote? Please phone 0345 464 0079 or send us an email and tell us about the job. We’ll explain what we’d do and give you a clear price before we start.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the sealant is paintable before painting near it
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Keep soil, plants and ivy away from the joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
