About our external mastic in Padworth Common
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you have panel joints letting water in and rigid filler in a joint that should flex, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Padworth Common is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Each job carries a 12-month guarantee.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What else we do in Padworth Common
Padworth Common: your questions answered
Can you help a landlord with a rental near Aldermaston station?
Yes. We work for landlords and agents as well as householders. You can phone 0345 464 0079 or email us with the details for a clear quote.
Can you do external mastic in Padworth Common?
Yes. Our work covers London and the South East, and Padworth Common is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
What external mastic looks like in Padworth Common
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like The Willink School? Then larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Aldermaston station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why it’s worth doing now in Padworth Common
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. Older cottages and farmhouses around Padworth Common can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

What affects the cost of external mastic
There’s no set price list, because no two jobs are the same. What we look at:
- Working hours on commercial sites
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
Asking for a quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
Need a quote? Please call 0345 464 0079 or email us with a few details. You will know what we plan to do, and what it will cost, before any work begins.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep movement joints as flexible joints, not mortar
- Have failed joints looked at early
- Deal with leaking gutters that soak the joints below
- Keep high-pressure jets off the joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
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, all bigger jobs than a reseal.
How it works
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. For a village or hamlet like Padworth Common, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Let us know about parking restrictions
Getting a quote
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
Related advice
What we’re called out for in Padworth Common
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Keep an eye out for any of the following:
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
For an older house near a landmark such as Church of St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant.
