Is Cryers Hill in your area for external mastic?
Yes, Cryers Hill is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
What do you need from me for a quote?
A short description and the location. If we need more, we will ask.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
How long does the job take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. We’ll confirm how long when we quote.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Never let anyone fill a movement joint with mortar
- Act on the first splits you see
- Check the sealant is paintable before painting near it
- Keep water from gutters off the wall
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Why it’s worth doing now in Cryers Hill
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. Where a wall is exposed, as many are in small places like Cryers Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
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’ll go through it with you.

When something else is needed
Sealant is not the answer to every problem, and we will tell you before we start. It won’t solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

External mastic in Cryers Hill: local notes
Historic houses like Hughenden Manor (about 1.3 miles south-west) are a reminder that the area around Cryers Hill has older buildings as well as new. 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.
Rented homes near High Wycombe station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of the Good Shepherd include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Great Kingshill Church of England Combined School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
