Questions from Bradley
Is external mastic in Bradley guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Bradley within the area you cover?
Yes. Bradley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
External mastic for homes and businesses in Bradley
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have joints pointed up with cement by mistake and weathered mastic that no longer stretches, we can put it right, whatever the surface.
Somewhere as small as Bradley, 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 12-month guarantee in Bradley and across Hampshire.

Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.

External mastic in Bradley: local notes
With historic houses such as Hall Place (about 1.9 miles south-east) nearby, there’s older building stock in the area around Bradley as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, 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 Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.
Bradley is about 5 miles west of Alton, in Hampshire. We provide external mastic to homes and businesses in Bradley and nearby, as part of our work across Hampshire. Across Hampshire, we cover 683 places, Bradley among them. Reading is on our list too, around 20 miles away.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Bradley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height

Related advice
Common problems we fix in Bradley
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Signs it’s time to call us include:
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
In and around Bradley, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- Whether you can choose the colour
- How much experience the applicator has
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Bradley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why us?
- Tidy, careful work
- Old sealant always removed completely
- We are fully insured
- An ARBOMaster approved applicator
