How we handle external mastic in Headley
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. If you’re dealing with joints where the bead has come unstuck and failed sealant between panels on a façade, we can put it right.
Around Headley, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Your job is guaranteed for a year, as with all our work.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Somewhere like Headley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Let us know about parking restrictions

Advice
Landlords, agents and businesses in Headley
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
When to call us in Headley
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
Most people get in touch when they notice one of these:
- Rigid filler in a joint that should flex
- Failed seals between different materials
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
Letting a property close to Liphook station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.

Headley buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as The Holme Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

Headley questions
Do you cover Headley for external mastic?
Yes, Headley is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Do you cover smaller places like Headley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
How often do external joints need resealing?
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 one-year guarantee.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Looking after it afterwards
Aftercare is simple:
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
- Don’t let climbing plants root in the sealant
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. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
