External mastic for homes and businesses in Hoaden
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We’re often asked to deal with sealant that has lost its bond to the brick or render and joints pointed up with cement by mistake, across façade panels, joints between brick and frames and render & cladding joints.
Older homes in small places like Hoaden may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job.

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Hoaden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Advice
Why act early in Hoaden
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. Older cottages and farmhouses around Hoaden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

When it isn’t the sealant
To be straight with you, there are a few things sealant will not fix:
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

How the job changes by surface
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and helps it last.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Hoaden questions
Do you work for landlords with property near Minster station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Hoaden?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.

What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Walls and rooflines in Hoaden
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Goodnestone Park (about 3.4 miles south) are a reminder that the area around Hoaden 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.
If you let a flat or house near Minster station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Ash Cartwright and Kelsey Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Elmstone Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Wash walls gently around the sealant
- Do not let climbing plants root in the sealant
- Show decorators and builders where the movement joints are
- Check the sealant is paintable before painting near it
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
