Landlord and commercial work in Hadleigh
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Landlords and letting agents in Hadleigh can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
External mastic in Hadleigh, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you have sealant that has lost its bond to the brick or render and brick movement joints where the sealant has split, we can put it right, on joints between brick and frames, façade panels and render & cladding joints alike.
Homes around Hadleigh range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Our work is backed for twelve months.

FAQs for Hadleigh
Will you come out to Hadleigh?
Yes. Hadleigh 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.
Does the coastal weather in Hadleigh affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Do you guarantee your work?
Yes. All our work carries a 12-month guarantee.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant is not too deep.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
- Façade panels
- Concrete & block
- Render & cladding joints
Common problems we fix in Hadleigh
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
It’s worth asking for a quote if you see:
- Joints with sealant missing in places
- Failed seals between different materials
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
In the older streets around Church of St James the Less, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Whether the sealant suits the joint
- How hidden problems are handled
- Who does the work, and how experienced they are

External mastic in Hadleigh: local notes
Hadleigh is within about 2 miles of 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Leigh-on-Sea station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Hadleigh Junior School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Hadleigh is about 2 miles south-east of Thundersley, in Essex. We carry out external mastic for homes and businesses in Hadleigh and the surrounding area, as part of our work across Essex. Hadleigh is one of 644 towns and villages in Essex where we work for external mastic. You can also see our page for Chelmsford, about 14 miles away.

Leave it or put it right?
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, rather than the wall around it. In a smaller place like Hadleigh, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Parking around Hadleigh is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
