External Mastic in Holton St Mary

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Act on the first splits you see
- Clear growth from the base of walls and joints
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
External mastic in Holton St Mary, done properly
For buildings in Holton St Mary, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have joints with sealant missing in places and cracked joints where brick meets render or frames, we can help, on brickwork movement joints, façade panels and joints between brick and frames alike.
Older homes in small places like Holton St Mary may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Every job is covered by a one-year guarantee, wherever you are in Essex.

Your questions about external mastic in Holton St Mary
I let a flat near Manningtree station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Holton St Mary?
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 seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
How long does external mastic take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we will say how long yours will take.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
How we quote for external mastic
We quote each job individually. These are the things that affect it:
- Which sealant suits the joint
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Pictures of the joints, sent by email
For a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. In a small place like Holton St Mary, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.

Holton St Mary buildings and the weather
Historic houses like Castle House (about 2.9 miles south) are a reminder that the area around Holton St Mary has older buildings as well as new. In older buildings, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as East Bergholt High School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Manningtree station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What the job involves on each surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. For a village or hamlet like Holton St Mary, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
