Helping us quote
To make quoting easier, let us know:
- Pictures of the joints, sent by email

External mastic in Phoenix Green, done properly
A movement joint is only as good as its depth. 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. Typical jobs include joints with sealant missing in places and leaking joints around cladding and façade panels, across façade panels, render & cladding joints and joints between brick and frames.
Somewhere as small as Phoenix Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

External mastic in Phoenix Green: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Greenfields Junior School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to St Mary's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Phoenix Green needs a little journey planning: 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.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Move anything stored near the joints
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In a small place like Phoenix Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Do you have insurance?
Yes. We’re fully insured.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
- Don’t let climbing plants root in the sealant
- Wash walls gently around the sealant
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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 we’re called out for in Phoenix Green
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Look out for any of the following:
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
For landlords with property near Winchfield station, outside joints that have cracked can let damp into a rental, so check them between lets.
Before booking anyone
- What the quote includes, VAT included or not
- Whether they’re fully insured
- Who turns up on the day
- What happens if they find a problem under the old sealant
Surface by surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
