External mastic for homes and businesses in Little Oakley
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. If you are dealing with hard, crazed mastic that has stopped moving and water getting into walls through failed joints, we can help, on joints between brick and frames, brickwork movement joints and render & cladding joints alike.
Older homes in small places like Little Oakley may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
All our work is covered by a one-year guarantee, wherever you are in Essex.

Common problems we fix in Little Oakley
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
People generally contact us when they notice one of these:
- Water getting into walls through failed joints
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
If you let a flat or house near Harwich International station, outside joints that have cracked can let damp into a rental, so check them between lets.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
- Damp that isn’t coming from the joint
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

Little Oakley buildings and the weather
Little Oakley is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
For site and facilities teams at buildings such as The Harwich School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as St Mary's House, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why act early in Little Oakley
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. Older cottages and farmhouses around Little Oakley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Little Oakley questions
Does the coastal weather in Little Oakley affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Harwich International station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move, and it should be sealed with a flexible sealant.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
How long will you be here?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. We will confirm how long when we quote.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Quotes for external mastic in Little Oakley
Your quote is based on your job. We look at:
- The type of sealant required
- The number and length of the joints
- Working hours on commercial sites
- Any mould that needs treating
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- Whether it has been sealed before
- Roughly how big the job is
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Leave the joints unpainted unless we have said otherwise
- Clear growth from the base of walls and joints
- Look over the joints every year, ideally after winter
- Show decorators and builders where the movement joints are
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. For a village or hamlet like Little Oakley, 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, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Related advice
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
