About our external mastic in Hatfield Broad Oak
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We work on façade panels, concrete & block and render & cladding joints, and people most often call us about failed sealant between panels on a façade and water getting into walls through failed joints.
Outside joints can only be sealed when they’re dry, so work in Hatfield Broad Oak is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, whatever its size.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Walls and rooflines in Hatfield Broad Oak
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Barrington Hall (about 0.7 miles north) are a reminder that the area around Hatfield Broad Oak 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.
If you live in an older home near Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common problems we fix in Hatfield Broad Oak
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
It’s worth asking for a quote if you see:
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
- Panel joints letting water in
Letting a property close to Sawbridgeworth station? Then split movement joints are easy to miss on a rental until damp shows inside.

Why it’s worth doing now in Hatfield Broad Oak
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. Around Hatfield Broad Oak, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What affects the quote in Hatfield Broad Oak
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Working hours on commercial sites
- Which sealant suits the joint
- The size of the job
- Whether the work is at height
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- The type of property
- Any previous sealing or DIY work
- A few pictures by email, if you can
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
Where we work in Hatfield Broad Oak
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Concrete & block
- Façade panels
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Do not let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
