Landlord and commercial work in Wendens Ambo
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams in Wendens Ambo and across Essex. Several sites can be quoted together, and we are fully insured.
How we handle external mastic in Wendens Ambo
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have old sealant gone brittle and cracked and joints where the bead has come unstuck, we can put it right, whatever the surface.
In a village or hamlet like Wendens Ambo, older cottages and farm buildings often stand in the open, 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.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It won’t 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
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Brickwork movement joints
- Façade panels
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
Surface by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
FAQs for Wendens Ambo
Is Wendens Ambo in your area for external mastic?
Yes. Our work covers London and the South East, and Wendens Ambo is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Audley End station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. In a small place like Wendens Ambo, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

What we’re called out for in Wendens Ambo
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
It’s worth asking for a quote if you see:
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
If you let a flat or house near Audley End station, split movement joints are easy to miss on a rental until damp shows inside.

External mastic in Wendens Ambo: local notes
With historic houses such as Audley End House (about 1.2 miles north-east) nearby, there’s older building stock in the area around Wendens Ambo as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
If you look after a building such as Joyce Frankland Academy, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
