External mastic in Padworth, done properly
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. Typical jobs include moss and dirt in joints with no sealant left and damp patches traced to an open external joint, on render & cladding joints, façade panels and joints between brick and frames.
Somewhere as small as Padworth, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Big or small, you get the same one-year guarantee in Padworth and across West Berkshire.

Common questions in Padworth
Is Padworth in your area for external mastic?
Yes, Padworth is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
I let a flat near Aldermaston station. Can you help?
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 drop us an email with the details for a clear quote.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
How long does the job take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Aftercare tips
Aftercare is simple:
- Don’t let climbing plants root in the sealant
- Point out the joints to other trades
- Make sure movement joints aren’t pointed over
- Get split or bare joints resealed while the damage is small
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
Honest limits
Before you book, it’s worth knowing the limits too:
- Damp that isn’t coming from the joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

How the visit works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the building, including the tidy-up. Somewhere as small as Padworth, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Let us know about parking restrictions

Advice
Common problems we fix in Padworth
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Common reasons people contact us include:
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
Letting a property close to Aldermaston station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

- Is VAT in the price?

How the job changes by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Padworth, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Walls and rooflines in Padworth
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Sulhamstead and Ufton Nervet School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move.
