External mastic in Milstead, done properly
Ground-floor and low-level joints are straightforward to reach. 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 sealant pulling away from one side of the joint and cracked joints where brick meets render or frames, we can put it right, on concrete & block, façade panels and brickwork movement joints alike.
Somewhere as small as Milstead, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee, large or small.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Act on the first splits you see
- Fix overflowing gutters above sealed joints
- Clear growth from the base of walls and joints
- Ask before painting over external sealant
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the building. In a small place like Milstead, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Your questions about external mastic in Milstead
Do you work for landlords with property near Sittingbourne station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you cover Milstead for external mastic?
Yes, Milstead is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How long does the job take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We will confirm how long when we quote.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
When to call us in Milstead
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 can’t stretch and rips as the joint opens.
These are the problems we’re asked about most:
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
Schools such as Milstead and Frinsted Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What external mastic looks like in Milstead
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.
For landlords with property near Sittingbourne station, split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Church of St Mary and the Holy Cross, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
