External mastic for Upper Sanday and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
- Sealant pulling away from one side of the joint
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for a handful of joints, longer for a whole elevation. Around Upper Sanday, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Advice
External mastic in Upper Sanday, done properly
On houses, flats and commercial buildings across Upper Sanday, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We’re often asked to deal with rigid filler in a joint that should flex and cracked joints where brick meets render or frames, across concrete & block, joints between brick and frames and brickwork movement joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Your job is guaranteed for a year, as with all our work.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Keep water from gutters off the wall
- Don’t let climbing plants root in the sealant
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
What affects the cost of external mastic
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- The amount of work
- Any mould that needs treating
- The number of rooms or windows
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
For a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. We will give you a clear quote before any work starts.
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.
When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.
Joints and surfaces we work on

Upper Sanday: your questions answered
Does the coastal weather in Upper Sanday affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover Upper Sanday for external mastic?
Yes. We work across all of Scotland, and Upper Sanday is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working, and the wall may crack nearby. We’ll reseal it with a flexible sealant.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Why it’s worth doing now in Upper Sanday
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Why book with us
- Experience in homes, commercial sites and hotels
- Quality sealants from Arbo and Everbuild
- A choice of colours where the product allows
- Any old sealant cut out fully, not covered over

Walls and rooflines in Upper Sanday
Upper Sanday is within about 1 mile of 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
Whether the job is in Upper Sanday itself or nearby, the right material for each joint matters as much as a neat finish. In and around Upper Sanday, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
