Your questions about external mastic in Lochluichart
Do you work for landlords with property near Lochluichart station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Lochluichart?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Should I point up the gap in my brickwork?
No. Cement or mortar cannot stretch. If it has already been filled, we can normally cut it out and reseal it.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
External mastic in Lochluichart
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you have moss and dirt in joints with no sealant left and weathered mastic that no longer stretches, we can help.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
- Failed render or damaged cladding panels
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

Signs you need external mastic in Lochluichart
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The problems people normally mention when they call include:
- Panel joints letting water in
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
Letting a property close to Lochluichart station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
Before booking anyone
- How much experience the applicator has
- What product goes in the joint
- What the quote includes, VAT included or not
- How long to leave it before use
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clear growth from the base of walls and joints
- Check external joints each spring
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

Walls and rooflines in Lochluichart
Lochluichart is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
In the older streets around Lochluichart Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Lochluichart is about 24 miles north-west of Inverness, in Highland.

How the job changes by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the amount of work. Outside jobs in Lochluichart need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Advice
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
