About our external mastic in Hinxton
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on joints between brick and frames, brickwork movement joints and façade panels, and common reasons people get in touch are brick movement joints where the sealant has split and hard, crazed mastic that has stopped moving.
Older homes in small places like Hinxton may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Your job is guaranteed for a year, as with all our work.

What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Common questions in Hinxton
Do you work for landlords with property near Whittlesford Parkway station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Hinxton in your area for external mastic?
Yes, Hinxton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Is there a guarantee?
Yes. Every job comes with our 12-month guarantee.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- 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.

How we quote for external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any mould that needs treating
- The type of sealant required
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
To make quoting easier, let us know:
- Roughly how big the job is
- Any access issues, like height or stairs
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or email us.
Landlord and commercial work in Hinxton
Landlords and letting agents in Hinxton can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. In a small place like Hinxton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What we’re called out for in Hinxton
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Keep an eye out for any of the following:
- Plants rooting in failed movement joints
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Panel joints letting water in
In the older streets around Parish Church of St Mary and St John the Evangelist, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- Which colour the sealant will be
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
- What insurance they hold
External mastic in Hinxton: local notes
With historic houses such as Audley End House (about 4.8 miles south) nearby, there’s older building stock in the area around Hinxton as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
