Questions from Mid Holmwood
Is Mid Holmwood within the area you cover?
Yes. Mid Holmwood is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Holmwood station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Do you use backing rod?
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.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
External mastic for homes and businesses in Mid Holmwood
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We work on concrete & block, façade panels and render & cladding joints, and people most often call us about joints pointed up with cement by mistake and brick movement joints where the sealant has split.
Outside joints can only be sealed when they’re dry, so work in Mid Holmwood is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months, in Mid Holmwood and everywhere else we cover.

Surface by surface
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
Leave it or put it right?
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. Where a wall is exposed, as many are in small places like Mid Holmwood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. It won’t solve:
- Rising or penetrating damp from elsewhere in the wall
- Render that is blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
What we seal
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Façade panels
- Copings & trims
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Mid Holmwood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

When to call us in Mid Holmwood
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
For landlords with property near Holmwood station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Is VAT in the price?
- Whether the sealant suits the joint
- Who turns up on the day

What external mastic looks like in Mid Holmwood
Historic houses like Polesden Lacey (about 4.2 miles north-west) are a reminder that the area around Mid Holmwood has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Managing a site like St John's Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of St John the Evangelist, older walls, gutters and the joints where extensions meet them need a flexible sealant.
