How we handle external mastic in Portree
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. Common call-outs are for panel joints letting water in and cracked joints where brick meets render or frames, on concrete & block, copings & trims and render & cladding joints.
In and around a place like Portree, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
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.

DIY versus a professional finish
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, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
For landlords and businesses
We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured.
Landlords and agents in Portree can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

Do you need external mastic in Portree?
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
Signs it’s time to call us include:
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
Homes close to St Columba's Episcopal Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

How the visit works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. The work usually takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Advice
When something else is needed
In fairness, there are a few things sealant will not fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

Outside joints around Portree
Portree 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 is hard on movement joints and outside wall joints, especially on the side facing the sea. The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Schools such as Portree High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.
Questions from Portree
Is Portree in your area for external mastic?
Yes. We work across all of Scotland, and Portree is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Does living near the coast affect external mastic in Portree?
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.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height and we’ll confirm how they can be reached safely.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Leave it or put it right?
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. In an older home around Portree, damp from a failed joint can get into timber and plaster.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
