External mastic in Ightham, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. Typical jobs include rigid filler in a joint that should flex and sealant pulling away from one side of the joint, across concrete & block, brickwork movement joints and joints between brick and frames.
External sealant needs dry, clean surfaces, so work around Ightham is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Every job comes with a one-year guarantee.

Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Ightham: your questions answered
Do you cover smaller places like Ightham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Ightham in your area for external mastic?
Yes. We work across London and the South East, and Ightham is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Where is Mr Mastic based?
We work from Crawley. We cover Ightham and the rest of Kent, along with the rest of our area.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Outside joints around Ightham
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Ightham Mote (about 1.5 miles south) nearby, there’s older building stock in the area around Ightham as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Borough Green & Wrotham station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Ightham Primary School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of St Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we do, step by step
At the end, we look at the finished work together. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Somewhere as small as Ightham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Related advice
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
- Structural movement, which needs a surveyor or engineer
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on

- Joints between brick and frames
Looking after it afterwards
After the cure time, these simple habits help:
- Fix overflowing gutters above sealed joints
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
