Surface 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.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
External mastic for homes and businesses in Wishanger Common
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. If you’re dealing with cracked joints where brick meets render or frames and movement joints filled with mortar instead of sealant, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Wishanger Common is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee.

Wishanger Common buildings and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Bentley (Hampshire) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Leave it or put it right?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Wishanger Common, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- The old material and how stubborn it is
- The product the joint needs
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
What we need to know
When you contact us, these details help:
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Common problems we fix in Wishanger Common
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Failed seals between different materials
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
If you live in an older home near St John the Evangelist, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Check the sealant is paintable before painting near it
- Keep high-pressure jets off the joints
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
When it isn’t the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Render that is blown, hollow or coming away
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Wishanger Common needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
