External mastic in Clifton Hampden
On houses, flats and commercial buildings across Clifton Hampden, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We are often asked to deal with brick movement joints where the sealant has split and cracked joints where brick meets render or frames, across render & cladding joints, copings & trims and brickwork movement joints.
In a village or hamlet like Clifton Hampden, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, you get the same 12-month guarantee in Clifton Hampden and across Oxfordshire.

When to call us in Clifton Hampden
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
If you can see any of these, it’s time to have the joints looked at:
- Joints where the bead has come unstuck
- Failed seals between different materials
- Rigid filler in a joint that should flex
- Plants rooting in failed movement joints
For site and facilities teams at buildings such as Clifton Hampden Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Whether they’re fully insured
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
- How long the guarantee is
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Ask before painting over external sealant
- Have failed joints looked at early
- Check external joints each spring
- Point out the joints to other trades
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.

What affects the cost of external mastic
Every job gets its own quote. These are the things that affect it:
- Any mould that needs treating
- The product the joint needs
- The number of rooms or windows
- Any working-time requirements on site
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- The problem you’ve noticed
- Photos by email, if that’s easy
- Roughly how big the job is
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.
Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Clifton Hampden buildings and the weather
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 Clifton Hampden Manor (about 0.1 miles east) nearby, there’s older building stock in the area around Clifton Hampden as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Culham station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Church of St Michael and All Angels, the joints between older walls, newer extensions and the roofline need a sealant that can move.

- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.

Advice
When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Cracked brickwork or render that needs a builder or plasterer
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.

Clifton Hampden questions
Do you cover smaller places like Clifton Hampden?
Yes. Clifton Hampden 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.
I let a flat near Culham station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What does external mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
How long does the job take?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. Your quote will say how long we expect yours to take.
