About our external mastic in Whitley
On houses, flats and commercial buildings across Whitley, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have failed sealant between panels on a façade and failed seals between different materials, we can put it right, on façade panels, brickwork movement joints and concrete & block alike.
In a smaller place like Whitley, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Keeping the joints in good condition
So the new joints stay in good condition:
- Do not let climbing plants root in the sealant
- Get split or bare joints resealed while the damage is small
- Never let anyone fill a movement joint with mortar
- Keep water from gutters off the wall
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
Questions from Whitley
Can you do external mastic in Whitley?
Yes, Whitley is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Is Whitley 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.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
How do I get a quote for external mastic in Whitley?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us and let us know what needs doing and where.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
What we are called out for in Whitley
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
If you can see any of these, it’s time to have the joints looked at:
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
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.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Whether they’re fully insured
- What product goes in the joint
- Who does the work, and how experienced they are

What else we do in Whitley
Work for landlords, hotels and businesses
Letting agents and landlords in Whitley can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY versus a professional finish
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’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
How the job changes by surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Whitley buildings and the weather
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.
If you live in an older home near St Agnes, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as John Madejski Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

How the visit works
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work normally takes anything from a few hours to several days, depending on the building. A visit to Whitley is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Keep children and pets away from the work area
