How we handle external mastic in College Town
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. If you’re dealing with old sealant gone brittle and cracked and joints pointed up with cement by mistake, we can help.
In and around College Town, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
There’s a 12-month guarantee on every job, whatever its size.

External mastic in College Town: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Blackwater station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Royal Memorial Chapel, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like College Town Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Why it’s worth doing now in College Town
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Homes in smaller places like College Town can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
What you get with us

What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it.
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
How to look after the new joints
So the new joints stay in good condition:
- Keep soil, plants and ivy away from the joints
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

What happens on the day

Most jobs take a few hours to a few days, depending on the length of joint and the access. Parking around College Town is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

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.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
