Should I try it myself first?
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 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.
About our external mastic in Whitley Wood
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. We work on joints between brick and frames, brickwork movement joints and concrete & block, and common reasons people get in touch are gaps where render, brick and frames meet and old sealant gone brittle and cracked.
In and around Whitley Wood, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
A one-year guarantee comes as standard.

Surface by surface
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. We reseal them with a sealant suited to the panel material.
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.
Why act early in Whitley Wood
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. In an older home around Whitley Wood, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:

What external mastic looks like in Whitley Wood
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Stratfield Saye House (about 4.9 miles south) are a reminder that the area around Whitley Wood has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Reading Green Park station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near St Paul's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

When to call us in Whitley Wood
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
Any of these means the joints need attention:
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
If you look after a building such as Geoffrey Field Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions from Whitley Wood
Is Whitley Wood within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Whitley Wood in your area for external mastic?
Yes, Whitley Wood is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. We’ll confirm how long when we quote.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render. Exterior sealants come in a good range of colours.

What affects the quote in Whitley Wood
You will get a clear quote before we start. It takes into account:
- Access and height
- Which sealant suits the joint
- Working hours on commercial sites

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

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 to a few days, depending on the length of joint and the access for a typical job.

- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
