External mastic for Forgandenny, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Clear growth from the base of walls and joints
- Ask before painting over external sealant
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
About our external mastic in Forgandenny
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. Common call-outs are for weeds or debris growing in open joints and panel joints letting water in, across render & cladding joints, façade panels and copings & trims.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Big or small, it’s backed by our one-year guarantee in Forgandenny and across Perth and Kinross.

The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. For a place like Forgandenny, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

When to call us in Forgandenny
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The most common problems we see are:
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
If you live in an older home near Forgandenny Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic in Forgandenny: local notes
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. 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.

When it isn’t the sealant

- Failed render or damaged cladding panels

- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

Why it’s worth doing now in Forgandenny
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Forgandenny, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
