External & façade joints in Passfield, Hampshire

External mastic in Passfield
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. We’re often asked to deal with weathered mastic that no longer stretches and failed seals between different materials, across façade panels, brickwork movement joints and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Passfield is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Your questions about external mastic in Passfield
Can you do external mastic in Passfield?
Yes, Passfield 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, and we will send you a clear quote.
Is Passfield within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
Surface by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. Sealant won’t put right:
- Subsidence or other structural problems
- Render that’s blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

What external mastic looks like in Passfield
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

What we are called out for in Passfield
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
Schools such as Mill Chase Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation from start to finish. Somewhere like Passfield needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Advice
What affects the quote in Passfield
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- How easy the joints are to reach
- How much there is to do
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- How we’d reach the joints
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Make sure movement joints aren’t pointed over
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
- Check the sealant is paintable before painting near it
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
