About our external mastic in Hook End
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you have weathered mastic that no longer stretches and plants rooting in failed movement joints, we can put it right.
Around Hook End, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Façade panels
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.

What else we do in Hook End
What affects the quote in Hook End
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Access and height
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.
Asking for a quote
When you contact us, it’s useful to know:
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- The rough size of the job
We do not publish a price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.
How it works
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. For a village or hamlet like Hook End, 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Hook End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Aftercare tips
A little care helps the new joints last. We recommend:
- Tell anyone working on the walls about the movement joints
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Have failed joints looked at early
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind.
Hook End: your questions answered
Is Hook End in your area for external mastic?
Yes, Hook End is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Shenfield station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
When will the joints need doing again?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Walls and rooflines in Hook End
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Ingatestone Hall (about 4.1 miles east) nearby, there’s older building stock in the area around Hook End as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Shenfield station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of All Saints 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 Doddinghurst Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
