External mastic in Broughton, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. We work on concrete & block, render & cladding joints and copings & trims, and common reasons people get in touch are sealant that has lost its bond to the brick or render and weathered mastic that no longer stretches.
In a smaller place like Broughton, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are normally the first to go.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What else we do in Broughton
How the visit works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. A visit to Broughton is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Advice
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the 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.
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
We also work for property managers and facilities teams. We can quote a run of properties together.
What affects the cost of external mastic
There’s no set price list. The quote depends on:
- The number of rooms or windows
- Any mould that needs treating
- Whether the work is at height
- The type of sealant required
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Can you help a landlord with a rental near Aylesbury station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can you do external mastic in Broughton?
Yes, Broughton is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How much does external mastic cost in Broughton?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.

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. Larger jobs naturally take longer, and we will say how long yours will take.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Walk round the building once a year and look at the joints
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Never let anyone fill a movement joint with mortar
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Signs you need external mastic in Broughton
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
The problems people usually mention when they call include:
- Moss and dirt in joints with no sealant left
- Leaking joints around cladding and façade panels
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
Schools such as Bierton Church of England Combined School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- Who does the work, and how experienced they are
- Which colour the sealant will be
Outside joints around Broughton
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Aylesbury station, outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
