External mastic across Reading: what to expect
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. Typical jobs include weeds or debris growing in open joints and joints pointed up with cement by mistake, on façade panels, copings & trims and render & cladding joints.
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

External mastic across Reading: local notes
In Reading, external mastic work takes in houses, flats and commercial buildings, from Caversham, Norcot and West Reading to the quieter places in between. Every outside joint is sealed dry and clean, so the forecast decides the day.
Hard water across most of the South East leaves limescale on sealant, grout and fittings. For any job in Reading, joints are cleaned back properly before anything new goes in.
Caversham: Managing a site like The Hill Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Reading station, split movement joints are easy to miss on a rental until damp shows inside.
Quotes for external mastic in Reading
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- Working hours on commercial sites
- Whether the work is at height
- The number and length of the joints
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- The address or postcode of the job
We do not publish a price list. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or email us.
Landlords, agents and businesses in Reading
For anyone letting property in or around Reading, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Keeping the joints in good condition
So the new joints stay in good condition:
- Point out the joints to other trades
- Check external joints each spring
- Keep water from gutters off the wall
- Keep movement joints as flexible joints, not mortar
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
How the job changes by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
Reading: your questions answered
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
How much does external mastic cost in Reading?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
