External mastic in Maudlin
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We are often asked to deal with sealant that has lost its bond to the brick or render and damp patches traced to an open external joint, on render & cladding joints, joints between brick and frames and concrete & block.
Around Maudlin, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Your job is guaranteed for a year, as with all our work.

Maudlin questions
Is Maudlin within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Maudlin for external mastic?
Yes. We work across London and the South East, and Maudlin is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins from the range available.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Landlord and commercial work in Maudlin
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
If you manage several properties in or around Maudlin, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Signs you need external mastic in Maudlin
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Look out for any of the following:
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
- Joints pointed up with cement by mistake
If you live in an older home near The Parish Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What else we do in Maudlin
Outside joints around Maudlin
Historic houses like Goodwood House (about 1.5 miles north) are a reminder that the area around Maudlin 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Chichester station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as The March CofE Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. In a small place like Maudlin, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What we can’t put right
It helps to know what we cannot do too:
- Movement that’s more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
- Damp that is not coming from the joint
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
- Façade panels
- Concrete & block
Why it’s worth doing now in Maudlin
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 Maudlin 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, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Deal with leaking gutters that soak the joints below
- Make sure movement joints aren’t pointed over
- Keep high-pressure jets off the joints
- Clear growth from the base of walls and joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
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.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
