External mastic in Braiswick
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. Typical jobs include sealant that has lost its bond to the brick or render and cracked joints where brick meets render or frames, across render & cladding joints, copings & trims and brickwork movement joints.
Older homes in small places like Braiswick may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best.
Work for landlords, hotels and businesses
For anyone letting property in or around Braiswick, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Do you need external mastic in Braiswick?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
These are the problems we’re asked about most:
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
For landlords with property near Colchester station, split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- Whether all the old sealant comes out first
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
- How long the guarantee is
How the visit works
Once we’re on site, we compare the joints with what we discussed. 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 Braiswick, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

Advice
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep high-pressure jets off the joints
- Have failed joints looked at early
- Point out the joints to other trades
- Walk round the building once a year and look at the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
Your questions about external mastic in Braiswick
Can you help a landlord with a rental near Colchester station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do external mastic in Braiswick?
Yes. Our work covers London and the South East, and Braiswick is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height and we will confirm how they can be reached safely.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
When something else is needed
New sealant can’t fix everything, and we will tell you before any work starts. It will not solve:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
- Render that’s blown, hollow or coming away
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.

Braiswick buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Colchester County High School for Girls, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Leonard include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
