How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Iden Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

When to call us in Iden Green
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
These are the problems we’re asked about most:
- Sealant that has lost its bond to the brick or render
- Weeds or debris growing in open joints
- Damp patches traced to an open external joint
- Old sealant gone brittle and cracked
In the older streets around Church of St George, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Before you book anyone
- What guarantee comes with the work
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In a small place like Iden Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.

What affects the cost of external mastic
We quote each job individually. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- The size of the job
- Whether the work is at height
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Photos by email, if that’s easy
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
- Keep high-pressure jets off the joints
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Different surfaces, different methods
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant isn’t too deep.
FAQs for Iden Green
Will you come out to Iden 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.
Do you cover Iden Green for external mastic?
Yes. Our work covers London and the South East, and Iden Green is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start from the range available.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Walls and rooflines in Iden Green
With historic houses such as Great Dixter (about 4.2 miles south) nearby, there’s older building stock in the area around Iden Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Benenden Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
