About our external mastic in Langdon Hills
Getting the depth right is half the job. 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 rain getting behind render or cladding at a joint and gaps where render, brick and frames meet, we can put it right, on concrete & block, joints between brick and frames and brickwork movement joints alike.
Outbuildings, garages and conservatories around homes in places like Langdon Hills add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the quote in Langdon Hills
There’s no set price list, because jobs vary so much. The quote depends on:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Any working-time requirements on site
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The type of property
- Any access issues, like height or stairs
- Photos by email, if that is easy
- The address or postcode of the job
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job, and photos are welcome.
Outside joints around Langdon Hills
Basildon, which Langdon Hills is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Laindon station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Lincewood Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

When something else is needed
A few problems are outside what sealant work can do:
- Damp that is not coming from the joint
- Loose or hollow render, which needs re-rendering
- Movement that’s more than a sealant joint can take

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours to a few days, depending on the length of joint and the access. A visit to Langdon Hills is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

Advice
Common questions in Langdon Hills
Will you come out to Langdon Hills?
Yes. Langdon Hills is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it worth replacing old sealant in an older home in Langdon Hills?
In most cases, yes, if it hasn’t been done for a while. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure.
How do I get a quote for external mastic in Langdon Hills?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
Are you insured?
Yes. Full insurance covers our work.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
What the job involves on each surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.

What else we do in Langdon Hills
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Looking after it afterwards
To keep the joints looking good and working properly:
- Show decorators and builders where the movement joints are
- Get split or bare joints resealed while the damage is small
- Never let anyone fill a movement joint with mortar
- Keep high-pressure jets off the joints
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible 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.
