Walls and rooflines in Cullicudden
Cullicudden is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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 Novar House (about 3.2 miles north-west) nearby, there’s older building stock in the area around Cullicudden as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Alness station? Then split movement joints are easy to miss on a rental until damp shows inside.

How we handle external mastic in Cullicudden
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, leaving it bonded to two faces so it can move with the wall. If you are dealing with sealant that has lost its bond to the brick or render and hard, crazed mastic that has stopped moving, we can help.
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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Signs you need external mastic in Cullicudden
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
The problems people generally mention when they call include:
- Sealant pulling away from one side of the joint
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
- Hard, crazed mastic that has stopped moving
For an older house near a landmark such as Cullicudden Church and burial ground, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Why it’s worth doing now in Cullicudden
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. A flexible sealant over backing rod is what the joint needs. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Your questions about external mastic in Cullicudden
Does the coastal weather in Cullicudden affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Cullicudden?
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.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including the preparation. We will confirm how long when we quote.
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. We pick a colour that works with both materials.
What affects the cost of external mastic
Your quote is based on your job. We take into account:

- The product the joint needs
- How many areas need sealing
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote

- Whether it’s a home or a business
- Whether it has been sealed before
- The rough size of the job

Keeping the joints in good condition
Looking after new joints is easy:
- Fix overflowing gutters above sealed joints
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
- Act on the first splits you see
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. For a place like Cullicudden, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- 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
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

Advice
Surface by surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
