St Ann's Green External Mastic
We cover St Ann's Green for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

- Failed sealant between panels on a façade
- Failed seals between different materials
External mastic in St Ann's Green, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We’re often asked to deal with cracked joints where brick meets render or frames and hard, crazed mastic that has stopped moving, across façade panels, joints between brick and frames and concrete & block.
Around St Ann's Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
There’s a 12-month guarantee on every job, large or small.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on the building. Somewhere as small as St Ann's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- On commercial sites, let us know about site rules
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

St Ann's Green: your questions answered
Do you cover smaller places like St Ann's Green?
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.
Can you help a landlord with a rental near Marden station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
What should I tell you?
A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
What affects the cost of external mastic
Call for a quick quote. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Any working-time requirements on site
- How many rooms, windows or areas are involved
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- Any previous sealing or DIY work
Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What the job involves on each surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
- 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.

Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Around St Ann's Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
