About our external mastic in Liurbost
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. If you have damp patches traced to an open external joint and hard, crazed mastic that has stopped moving, we can help.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What else we do in Liurbost
Walls and rooflines in Liurbost
Liurbost is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Homes close to Parish Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
Liurbost is in Na h-Eileanan Siar. Jobs in Liurbost get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. 87 places in Na h-Eileanan Siar are on our list, from the larger towns to small villages.

Questions from Liurbost
Can you do external mastic in Liurbost?
Yes. Our work covers the whole of Scotland, and Liurbost is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Will you come out to Liurbost?
Yes, Liurbost is covered. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
How long does the job take?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. We will confirm how long when we quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
Are you fully insured?
Yes. We are fully insured for every job we do.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
For landlords and businesses
Landlords and letting agents in Liurbost can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
For anyone letting property in or around Liurbost, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
When to call us in Liurbost
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
The problems people normally mention when they call are:
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
- Joints pointed up with cement by mistake
In and around Liurbost, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Get split or bare joints resealed while the damage is small
- Make sure movement joints aren’t pointed over
- Ask before painting over external sealant
- Wash walls gently around the sealant
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
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.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. For a place like Liurbost, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
