How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
External mastic in Timsbury
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Typical jobs include movement joints filled with mortar instead of sealant and plants rooting in failed movement joints, across façade panels, joints between brick and frames and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Timsbury is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Quotes for external mastic in Timsbury
Every job gets its own quote. These are the things that affect it:
- How many areas need sealing
- Whether the work is at height
- Any mould that needs treating
- The product the joint needs
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
Before you ask for a quote, have a think about:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Outside joints around Timsbury
With historic houses such as Mottisfont Abbey (about 1.6 miles north-west) nearby, there’s older building stock in the area around Timsbury as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among 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 Andrew, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Mottisfont & Dunbridge station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Questions from Timsbury
Is Timsbury within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Mottisfont & Dunbridge station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
What does external mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What is backing rod for?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Is the work guaranteed?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
How long will you be here?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
Leave it or put it right?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Older cottages and farmhouses around Timsbury 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: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

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.

Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Render that is blown, hollow or coming away
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Façade panels
- Render & cladding joints
- Brickwork movement joints
What we are called out for in Timsbury
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
People normally contact us after spotting one of these:
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
- Leaking joints around cladding and façade panels
If you look after a building such as Stanbridge Earls School, larger buildings have long runs of movement joint that eventually need resealing.

- How hidden problems are handled
