How we handle external mastic in Flete
For buildings in Flete, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on concrete & block, brickwork movement joints and façade panels, and common reasons people get in touch are failed sealant between panels on a façade and plants rooting in failed movement joints.
Older homes in small places like Flete may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

External mastic in Flete: local notes
Flete is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as St Gregory's Catholic Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St. Catherine's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Flete is about 1 mile south-west of Margate, in Kent. Flete gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Flete is one of 922 towns and villages in Kent where we work for external mastic. There’s also a page for Chelmsford, about 46 miles away.

Local landmarks in Flete
Around Flete, our work takes us to homes and buildings near Hartsdown Academy. For rail, the closest station is Margate station, about 1.5 miles north. A little further out are Queen Elizabeth the Queen Mother Hospital (1.3 miles north-east) and Westwood Cross (1.1 miles east). Not far away are Sandwich and Pegwell Bay.
When to call us in Flete
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Keep an eye out for any of the following:
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
Letting a property close to Margate station? Then split movement joints are easy to miss on a rental until damp shows inside.

What else we do in Flete
How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- How many areas need sealing
- The type of sealant required
- The old material and how stubborn it is
- The amount of work
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
What we need to know
To make quoting easier, please include:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- The type of property
- How many joints, rooms or windows are involved
For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. We will send you a clear quote before any work starts.
Different surfaces, different methods
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
Common questions in Flete
Is external mastic in a coastal place like Flete any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Can you help a landlord with a rental near Margate station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
How long does external mastic last?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose. We will reseal it with a flexible sealant.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. Somewhere as small as Flete, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

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, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Leave it or put it right?
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. In a small place like Flete, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
