About our external mastic in Elvanfoot
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. Typical jobs include hard, crazed mastic that has stopped moving and joints pointed up with cement by mistake, across brickwork movement joints, copings & trims and façade panels.
External sealant needs dry surfaces, so outdoor work around Elvanfoot is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
We stand behind the work with a 12-month guarantee.

Do you need external mastic in Elvanfoot?
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Common reasons people contact us are:
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
For jobs in and around Elvanfoot, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- How hidden problems are handled
- Which colour the sealant will be
- Whether VAT is included
- Is the old sealant removed completely?
Landlord and commercial work in Elvanfoot
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Why act early in Elvanfoot
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Around Elvanfoot, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Sealant colour chosen to suit
- Homes, businesses and hotels
- White, clear, grey or another colour, product permitting

The process
On the day, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a place like Elvanfoot, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.

Walls and rooflines in Elvanfoot
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Make sure movement joints aren’t pointed over
- Have failed joints looked at early
- Keep high-pressure jets off the joints
- Clear growth from the base of walls and joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
