How we handle external mastic in Egypt
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We work on brickwork movement joints, joints between brick and frames and concrete & block, and people most often call us about joints with sealant missing in places and sealant that has lost its bond to the brick or render.
Older homes in small places like Egypt may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

FAQs for Egypt
Can you do external mastic in Egypt?
Yes, Egypt is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Burnham station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we will tell you how long to expect.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. A flexible sealant is the right fill.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.
How we quote for external mastic
You’ll get a clear quote before any work starts. It takes into account:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The type of sealant required
- Whether the work is at height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
To make quoting easier, please include:
- The rough size of the job
- The address or postcode of the job
- If someone has resealed it before
- A few pictures by email, if you can
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
Why act early in Egypt
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Egypt, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
Why us?
- Colour picked to suit the job
- Anti-fungal sanitary silicone in wet areas
- Every job guaranteed for a year
- White, clear, grey or another colour, product permitting

Outside joints around Egypt
With historic houses such as Cliveden (about 3 miles west) nearby, there’s older building stock in the area around Egypt as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St John the Evangelist, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Farnham Common Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Egypt needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
How to get a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Show decorators and builders where the movement joints are
- Look over the joints every year, ideally after winter
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Common problems we fix in Egypt
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Common reasons people contact us include:
- Sealant that has lost its bond to the brick or render
- Gaps where render, brick and frames meet
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
For landlords with property near Burnham station, split movement joints are easy to miss on a rental until damp shows inside.
