External mastic in Rookley Green, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall. Typical jobs include movement joints filled with mortar instead of sealant and old sealant gone brittle and cracked, across render & cladding joints, copings & trims and brickwork movement joints.
Older homes in small places like Rookley Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
You get a 12-month guarantee, the same in Rookley Green as everywhere else we work.

Rookley Green: your questions answered
Do you cover Rookley Green for external mastic?
Yes. Our work covers London and the South East, and Rookley Green is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Shanklin station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Make sure movement joints aren’t pointed over
- Walk round the building once a year and look at the joints
- Do not let climbing plants root in the sealant
- Get split or bare joints resealed while the damage is small
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.

What else we do in Rookley Green
When to call us in Rookley Green
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
Letting a property close to Shanklin station? Then split movement joints are easy to miss on a rental until damp shows inside.

The process
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. For a village or hamlet like Rookley Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear the area around the work
- Let us know about stairs, lifts or work at height

Why deal with it now?
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 Rookley Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Why book with us
- A 12-month guarantee on all work
- Trusted Arbo and Everbuild sealants
- Approved under the ARBOMaster scheme
- 180+ five-star Google reviews
When something else is needed
We will not take on work that won’t last, so these are the limits:
- Cracking across the wall rather than at a joint
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
What we seal
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Concrete & block
- Façade panels
- Joints between brick and frames
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What affects the quote in Rookley Green
We don’t publish a price list. The quote depends on:
- Whether there’s mould to deal with
- The amount of work
- The old material and how stubborn it is
- The product the joint needs
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before work begins.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- Whether it’s a home or a business
- Photos by email, if that’s easy
If you’re in Rookley Green and need external mastic, call 0345 464 0079 or drop us an email. Tell us what the problem is and where, and you’ll get a clear quote before any work starts.
