How we handle external mastic in Fickleshole
On houses, flats and commercial buildings across Fickleshole, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on render & cladding joints, joints between brick and frames and copings & trims, and the jobs we see most are leaking joints around cladding and façade panels and old sealant gone brittle and cracked.
Somewhere as small as Fickleshole, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. In a small place like Fickleshole, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- Clear the area around the work

Advice
Questions from Fickleshole
Is Fickleshole within the area you cover?
Yes. Fickleshole is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Fickleshole in your area for external mastic?
Yes. We work across London and the South East, and Fickleshole is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
How long does external mastic take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
How long should I leave it?
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.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Where we work in Fickleshole
- Copings & trims
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
Different surfaces, different methods
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.

Fickleshole buildings and the weather
With historic houses such as Down House (about 2.6 miles east) nearby, there’s older building stock in the area around Fickleshole as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Leonard include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Woldingham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Signs you need external mastic in Fickleshole
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
For site and facilities teams at buildings such as Fairchildes Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Is VAT in the price?
- Are they insured?
- How much experience the applicator has
- How the surfaces are prepared before sealing
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Fickleshole can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
