How we handle external mastic in Abshot
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the joint does not stand out. We work on brickwork movement joints, concrete & block and joints between brick and frames, and common reasons people get in touch are old sealant gone brittle and cracked and leaking joints around cladding and façade panels.
Outside joints can only be sealed when they’re dry, so work in Abshot is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why deal with it now?
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Abshot can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Never let anyone fill a movement joint with mortar
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Abshot, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts

Advice
Your questions about external mastic in Abshot
Will you come out to Abshot?
Yes, Abshot is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is external mastic in a coastal place like Abshot any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint does not draw the eye.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long does external mastic last?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.

Abshot buildings and the weather
Abshot is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Locks Heath Infant School, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Swanwick station, split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as St John, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
