What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
About our external mastic in Standford
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. We’re often asked to deal with joints where the bead has come unstuck and gaps where render, brick and frames meet, on concrete & block, render & cladding joints and façade panels.
Somewhere as small as Standford, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Our work is backed for twelve months, in Standford and everywhere else we cover.

Questions from Standford
Will you come out to Standford?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Standford for external mastic?
Yes, Standford is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Act on the first splits you see
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
- Make sure movement joints aren’t pointed over
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
What external mastic looks like in Standford
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.
For site and facilities teams at buildings such as Weyford Nursery and Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Liphook station? Then split movement joints are easy to miss on a rental until damp shows inside.

What’s near Standford
Around Standford, our work takes us to homes and buildings near Mill Chase Academy. Standford’s nearest station is Liphook station, roughly 2.9 miles south-east of the centre. Nearby you’ll also find Chase Community Hospital (1.1 miles west). Green spaces nearby include Wheeler's Down and Deadwater Valley.
Common problems we fix in Standford
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
If you can see any of these, it’s time to have the joints looked at:
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
Homes close to St Mark's Sacred Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before booking
- What insurance they hold
- Which colour the sealant will be
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Standford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Standford, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
