About our external mastic in Strachur
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. We work on joints between brick and frames, copings & trims and concrete & block, and common reasons people get in touch are brick movement joints where the sealant has split and failed seals between different materials.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
There’s a 12-month guarantee on every job, whatever its size.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Strachur buildings and the weather
Strachur is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Inveraray Castle (about 4.9 miles north) nearby, there’s older building stock in the area around Strachur as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In and around Strachur, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. For an older house near a landmark such as Kilmaglash Parish Church and Sculptured Stones, an extension built onto an older house moves differently, and the joint between them takes the strain.

Your questions about external mastic in Strachur
Does living near the coast affect external mastic in Strachur?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you cover smaller places like Strachur?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk and let us know what needs doing and where.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
How do you reach high-level joints?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal

Why it’s worth doing now in Strachur
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

What the job involves on each surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for 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.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Check external joints each spring
- Keep high-pressure jets off the joints
- Ask before painting over external sealant
- Have failed joints looked at early
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
