What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
- Whether there’s mould to deal with
- When we can work, for business premises
- The number and length of the joints
- The type of sealant required
Some things make a job bigger or smaller: 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 to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or drop us an email.

External mastic in Green Street: local notes
With historic houses such as Ingatestone Hall (about 1.9 miles south-east) nearby, there’s older building stock in the area around Green Street as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
If you live in an older home near Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Ingatestone Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Green Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on

Different surfaces, different methods
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.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Green Street questions
Do you work for landlords with property near Ingatestone station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do external mastic in Green Street?
Yes. We work across London and the South East, and Green Street is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Can you do several jobs on one visit?
Yes. Just list everything you need.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Can you work on commercial sites?
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.
Common problems we fix in Green Street
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we are asked about most:
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
- Joints pointed up with cement by mistake
- Panel joints letting water in
Rented homes near Ingatestone station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether the sealant suits the joint
- Are they insured?
- How much experience the applicator has
- Whether VAT is included
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Green Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Have failed joints looked at early
- Wash walls gently around the sealant
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
