External mastic in Speldhurst
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on concrete & block, copings & trims and render & cladding joints, and common reasons people get in touch are joints where the bead has come unstuck and cracked joints where brick meets render or frames.
Somewhere as small as Speldhurst, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What happens if it’s left?
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Older cottages and farmhouses around Speldhurst can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Tell anyone working on the walls about the movement joints
- Do not let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
What affects the quote in Speldhurst
You will get a clear quote before any work starts. It takes into account:
- How many areas need sealing
- The number and length of the joints
- Working hours on commercial sites
- The product the joint needs
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or drop us an email.
What external mastic looks like in Speldhurst
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. Historic houses like Penshurst Place (about 2.1 miles north-west) are a reminder that the area around Speldhurst 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.
If you look after a building such as Speldhurst Church of England Voluntary Aided Primary School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Mary the Virgin include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Tunbridge Wells station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Structural movement, which needs a surveyor or engineer
- Damp that is not coming from the joint
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
Surfaces we seal
- Copings & trims
- Façade panels

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Somewhere like Speldhurst needs a little journey planning: 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.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any tricky access
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
