About our external mastic in Viables
A movement joint is only as good as its depth. 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 work on copings & trims, concrete & block and façade panels, and people most often call us about hard, crazed mastic that has stopped moving and failed seals between different materials.
Outbuildings, garages and conservatories around homes in places like Viables add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
There’s a 12-month guarantee on every job, large or small.

What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the building. A visit to Viables is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

Why it’s worth doing now in Viables
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. Homes in smaller places like Viables can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Walls and rooflines in Viables
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 The Vyne (about 3.9 miles north) are a reminder that the area around Viables has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Basingstoke station, outside joints that have cracked can let damp into a rental, so check them between lets.

FAQs for Viables
Do you cover Viables for external mastic?
Yes, Viables is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.
Will you come out to Viables?
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.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What does external mastic cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
- Do not let climbing plants root in the sealant
- Wash walls gently around the sealant
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Once a joint cannot move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Common problems we fix in Viables
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
If you look after a building such as St John's Church of England Voluntary Aided Primary School, its movement joints, gutters and trims need looking after like any other building’s.
