Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Bucks Green, 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.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Your questions about external mastic in Bucks Green
Is Bucks Green in your area for external mastic?
Yes, Bucks Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Christs Hospital station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
How much does external mastic cost in Bucks Green?
Size, access and the old material all affect the cost. Call for a quick quote.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Render that is blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Render & cladding joints
- Façade panels
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
Common problems we fix in Bucks Green
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
Keep an eye out for these signs:
- Joints where the bead has come unstuck
- Failed seals between different materials
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
In the older streets around St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- What preparation is included
- The length of the guarantee
- Whether they seal over old material or remove it
What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- The product the joint needs
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
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, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Why it’s worth doing now in Bucks Green
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Bucks Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
