External mastic in Hook Park Estate
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on copings & trims, façade panels and render & cladding joints, and people most often call us about movement joints filled with mortar instead of sealant and leaking joints around cladding and façade panels.
Older homes in small places like Hook Park Estate may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Every job comes with a one-year guarantee.

Hook Park Estate: your questions answered
Does living near the coast affect external mastic in Hook Park Estate?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Can you help a landlord with a rental near Hamble station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
What should I tell you?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will give you a better idea when we quote.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint does not draw the eye.
Looking after it afterwards
So the new joints stay in good condition:
- Never let anyone fill a movement joint with mortar
- Check external joints each spring
- Show decorators and builders where the movement joints are
- Fix overflowing gutters above sealed joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
Hook Park Estate buildings and the weather
Hook Park Estate is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Hook-With-Warsash Church of England Academy, its movement joints, gutters and trims need looking after like any other building’s.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Hook Park Estate, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Hook Park Estate, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

Common problems we fix in Hook Park Estate
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall and make things worse.
Keep an eye out for these signs:
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
For landlords with property near Hamble station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Different surfaces, different methods
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
