External mastic in Marsh Green
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We’re often asked to deal with joints where the bead has come unstuck and cracked joints where brick meets render or frames, across copings & trims, joints between brick and frames and render & cladding joints.
Older homes in small places like Marsh Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
You get a 12-month guarantee, the same in Marsh Green as everywhere else we work.

Common questions in Marsh Green
Is Marsh Green within the area you cover?
Yes. Marsh Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Edenbridge Town station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We will give you a better idea when we quote.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Signs you need external mastic in Marsh Green
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Panel joints letting water in
Homes close to Marsh Green Mission Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Is the old sealant removed completely?
- What the quote includes, VAT included or not
- How much experience the applicator has
- Whether they’re fully insured
Different surfaces, different methods
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.

Why act early in Marsh Green
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Around Marsh Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.

External mastic in Marsh Green: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hever Castle (about 2.6 miles east) are a reminder that the area around Marsh Green 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.
Letting a property close to Edenbridge Town station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What affects the cost of external mastic
Call for a quick quote. What matters most is:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The number of rooms or windows
- Whether the work is at height
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
To help us quote quickly, let us know:
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- If someone has resealed it before
We don’t publish a price list, because every job is different. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or drop us an email.
The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Marsh Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
