External mastic in Hillhead
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. Common call-outs are for failed seals between different materials and weeds or debris growing in open joints, across render & cladding joints, copings & trims and concrete & block.
Around Hillhead, 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.
Each job carries a 12-month guarantee, large or small.

Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a small place like Hillhead, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Your questions about external mastic in Hillhead
Will you come out to Hillhead?
Yes, Hillhead is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Hamble station?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What affects the quote in Hillhead
Your quote is based on your job. We take into account:
- The number and length of the joints
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.
Walls and rooflines in Hillhead
Hillhead 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Hamble station, outside joints that have cracked can let damp into a rental, so check them between lets.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, 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.

When it is not the sealant
A few problems are outside what sealant work can do:
- Structural movement, which needs a surveyor or engineer
- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.

What we do, step by step
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In a small place like Hillhead, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- 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
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

What we are called out for in Hillhead
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Common reasons people contact us are:
- Plants rooting in failed movement joints
- Movement joints with cracked, split or missing sealant
- Panel joints letting water in
- Sealant pulling away from one side of the joint
For an older house near a landmark such as St George, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Is VAT in the price?
- Are they insured?
- The length of the guarantee
- What product goes in the joint
