About our external mastic in Hookwood
For buildings in Hookwood, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you’re dealing with rigid filler in a joint that should flex and water getting into walls through failed joints, we can put it right, on concrete & block, copings & trims and brickwork movement joints alike.
Older homes in small places like Hookwood may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Signs you need external mastic in Hookwood
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Signs it’s time to call us include:
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
If you look after a building such as Manorfield Primary and Nursery School, larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours to a few days, depending on the length of joint and the access, depending on the amount of work. For a village or hamlet like Hookwood, 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 look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work

Advice
Outside joints around Hookwood
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Bartholomew, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Horley station, split movement joints are easy to miss on a rental until damp shows inside.
Hookwood is about 1 mile south-west of Horley, in Surrey. Our applicators cover external mastic for homes and businesses in Hookwood and nearby, as part of our work across Surrey. Hookwood is one of 395 towns and villages in Surrey we cover for external mastic.

We also cover the places around Hookwood: Horley (1 mile north-east), Fernhill (2 miles east), Tinsley Green (2 miles south-east), Langley Green (3 miles south) and Shipley Bridge (3 miles south-east).

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Subsidence or other structural problems
- Render that’s blown, hollow or coming away
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

Hookwood questions
Is Hookwood within the area you cover?
Yes, we do. 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.
Can you do external mastic in Hookwood?
Yes, Hookwood is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Why deal with it now?
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, rather than the wall around it. Older cottages and farmhouses around Hookwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
