External mastic in Coillore
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. Common call-outs are for joints with sealant missing in places and joints pointed up with cement by mistake, across brickwork movement joints, concrete & block and render & cladding joints.
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.
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.

How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outside jobs in Coillore need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Your questions about external mastic in Coillore
Is Coillore within the area you cover?
Yes. Coillore is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Coillore affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We will tell you when we quote.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
How do I get a quote for external mastic in Coillore?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk and tell us what needs doing and where.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In an older home around Coillore, damp from a failed joint can get into timber and plaster.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.
Why book with us
- We are fully insured
- Approved under the ARBOMaster scheme
- Domestic, commercial and hotel work
- We never seal over old sealant
External mastic in Coillore: local notes
Coillore is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Coillore, as everywhere, external mastic is only as good as the preparation behind it.
Coillore is in Highland. Every kind of property in Coillore is covered for external mastic, old or new, large or small. Every job comes with our one-year guarantee. Coillore is one of 253 places in Highland we cover for external mastic.

Do you need external mastic in Coillore?
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
For jobs in and around Coillore, choosing the right material for each joint is as important as a tidy finish.

What affects the quote in Coillore
Some jobs are bigger than they look, and some smaller. The main factors:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- The amount of work
- How many rooms, windows or areas are involved
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
