How we handle external mastic in Hensting
On houses, flats and commercial buildings across Hensting, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Typical jobs include gaps where render, brick and frames meet and weathered mastic that no longer stretches, on façade panels, copings & trims and concrete & block.
External sealant needs dry, clean surfaces, so work around Hensting is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Whatever the size of the job, it’s backed by our one-year guarantee.

FAQs for Hensting
Do you work for landlords with property near Shawford station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is Hensting within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
How do I get a quote for external mastic in Hensting?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email and tell us what needs doing and where.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Why deal with it now?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way and it means sorting access once. Older cottages and farmhouses around Hensting can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits. We will send you a clear quote for the lot.

What happens on the day
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. In a small place like Hensting, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

Related advice
What we’re called out for in Hensting
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Signs it’s time to call us include:
- Cracked joints where brick meets render or frames
- Joints with sealant missing in places
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
In the older streets around Church of the Holy Trinity, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before you book anyone
- Who turns up on the day
- Which sealant they’ll use, and why
- What guarantee comes with the work
- Is VAT in the price?
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
- Tell anyone working on the walls about the movement joints
- Never let anyone fill a movement joint with mortar
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
