About our external mastic in Oad Street
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. We work on copings & trims, joints between brick and frames and render & cladding joints, and common reasons people get in touch are movement joints filled with mortar instead of sealant and failed sealant between panels on a façade.
Around Oad Street, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before the bead.

Oad Street: your questions answered
I let a flat near Newington station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Oad Street within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
- Movement that is more than a sealant joint can take
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- Which sealant suits the joint
- The old material and how stubborn it is
- The size of the job
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, let us know:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- Where the job is, and your postcode
We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details, and photos are welcome.
Should I try it myself first?
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Common problems we fix in Oad Street
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
The problems people generally mention when they call include:
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
- Hard, crazed mastic that has stopped moving
- Gaps where render, brick and frames meet
For an older house near a landmark such as Church of St Peter and St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic in Oad Street: local notes
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 landlords with property near Newington station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Borden Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Why act early in Oad Street
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Older cottages and farmhouses around Oad Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
