How we handle external mastic in Capel
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. If you’re dealing with weeds or debris growing in open joints and weathered mastic that no longer stretches, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Capel is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, whatever its size.

Common questions in Capel
Can you help a landlord with a rental near Ockley station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Capel?
Yes, Capel is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
How much does external mastic cost in Capel?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
How we quote for external mastic
For a quick quote, just ask. The main things that affect it are:
- The amount of work
- Whether the work is at height
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
External mastic in Capel: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Ockley station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why act early in Capel
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Capel, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we do, step by step
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. For a village or hamlet like Capel, 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.
- Each joint is checked and the colour of the new sealant agreed.
- 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.

Advice
What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
If the façade has a specified sealant, that is what we use, or one the system allows. Send us any details you have about the façade.
Common problems we fix in Capel
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
The problems people normally mention when they call include:
- Old sealant gone brittle and cracked
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
Managing a site like Scott Broadwood CofE Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Before booking anyone
- How much experience the applicator has
- What happens if the job turns out different
- When the joint can take water or movement
- Are they insured?
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.
