External mastic in Swan Street
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. Common call-outs are for water getting into walls through failed joints and rigid filler in a joint that should flex, across render & cladding joints, copings & trims and joints between brick and frames.
Somewhere as small as Swan Street, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months, in Swan Street and everywhere else we cover.

Signs you need external mastic in Swan Street
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint can’t move, so the wall cracks somewhere else instead.
Look out for these signs:
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
- Joints pointed up with cement by mistake
- Failed sealant between panels on a façade
For an older house near a landmark such as Church of St Barnabas, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- The length of the guarantee
- How the colour is chosen
- What preparation is included
- Which sealant they’ll use, and why
Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Joints between brick and frames
- Render & cladding joints

What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- Any working-time requirements on site
- Any mould that needs treating
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
Leave it or put it right?
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Swan Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why book with us
- Homes, businesses and hotels
- You choose the colour before work begins
- Old sealant always removed completely
- A sealant colour to suit the surroundings

What external mastic looks like in Swan Street
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.
If you let a flat or house near Chappel & Wakes Colne station, outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Chappel Church of England Controlled Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Swan Street: your questions answered
Is Swan Street within the area you cover?
Yes. Swan Street 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.
Do you cover Swan Street for external mastic?
Yes. We work across London and the South East, and Swan Street is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
How long does the job take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we will tell you how long to expect.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Work for landlords, hotels and businesses
Letting agents and landlords in Swan Street can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
If you manage several properties in or around Swan Street, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
- Show decorators and builders where the movement joints are
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
How the visit works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Swan Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
