What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way and it means sorting access once. Around Boquhan, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

About our external mastic in Boquhan
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on joints between brick and frames, façade panels and concrete & block, and the jobs we see most are panel joints letting water in and weeds or debris growing in open joints.
In and around a place like Boquhan, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
Your job is guaranteed for a year, as with all our work.

How the visit works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. Outside jobs in Boquhan need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- 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.
Before we arrive
- Tell us about any water getting in
- Keep children and pets away from the work area
- Mention any tricky access

Walls and rooflines in Boquhan
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Balfron High School, larger buildings have long runs of movement joint that eventually need resealing. In and around Boquhan, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check the sealant is paintable before painting near it
- Don’t let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed 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.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.

Boquhan questions

All our work, in Boquhan and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
How long does external mastic take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we’ll tell you how long to expect.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you quote for more than one area?
Yes. Just list everything you need.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
