External mastic for homes and businesses in Hangersley
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you are dealing with weathered mastic that no longer stretches and joints where the bead has come unstuck, we can put it right, on copings & trims, concrete & block and façade panels alike.
Older homes in small places like Hangersley may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A one-year guarantee comes as standard.

What we are called out for in Hangersley
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Panel joints letting water in
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Sealant pulling away from one side of the joint
Schools such as Poulner Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Your questions about external mastic in Hangersley
Will you come out to Hangersley?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is external mastic in Hangersley guaranteed?
All our work, in Hangersley and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before any work starts from the range available.
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 will explain our choice.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we’ll tell you how long to expect.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
What do you need from me for a quote?
Let us know what needs doing and where, with photos by email if possible. If we need more, we will ask.
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Hangersley needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
- Subsidence or other structural problems
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Concrete & block
- Façade panels
- Copings & trims
- Render & cladding joints

- Brickwork movement joints
Why act early in Hangersley
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Hangersley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

External mastic in Hangersley: local notes
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. With historic houses such as Avon Tyrrell House (about 4.1 miles south) nearby, there’s older building stock in the area around Hangersley as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to St John the Baptist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
