Woodham Mortimer External Mastic
We cover Woodham Mortimer for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
External mastic in Woodham Mortimer
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. If you are dealing with failed seals between different materials and leaking joints around cladding and façade panels, we can help, whatever the surface.
Around Woodham Mortimer, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What we can’t put right
We will not take on work that will not last, so here’s what sealant can’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Render that’s blown, hollow or coming away
- Movement that is more than a sealant joint can take
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

Signs you need external mastic in Woodham Mortimer
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Look out for any of the following:
- Failed seals between different materials
- Leaking joints around cladding and façade panels
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
Homes close to Church of St Margaret include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- Which colour the sealant will be
- Is VAT in the price?
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid pressure-washing directly into sealant joints
- Do not let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
- Make sure movement joints aren’t pointed over
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Older cottages and farmhouses around Woodham Mortimer can have timber 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. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

External mastic in Woodham Mortimer: local notes

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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
