Aftercare tips
To keep the joints looking good and working properly:
- Act on the first splits you see
- Clear growth from the base of walls and joints
- Point out the joints to other trades
- Ask before painting over external sealant
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
How we handle external mastic in Skittle Green
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you’re dealing with brick movement joints where the sealant has split and rigid filler in a joint that should flex, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Skittle Green is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All our work is covered by a 12-month guarantee, wherever you are in Buckinghamshire.

Advice
Skittle Green buildings and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Princes Risborough station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Princes Risborough School, larger buildings have long runs of movement joint that eventually need resealing.

When something else is needed
A few problems are outside what sealant work can do:
- Movement that’s more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

Signs you need external mastic in Skittle Green
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall.
These are the problems we are asked about most:
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
If you live in an older home near Church of the Holy Trinity, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
How do you reach high-level joints?
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 will confirm what’s needed.
When will the joints need doing again?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
