External & façade joints in Portlethen Village, Aberdeen
Our applicators work in Portlethen Village on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
How we handle external mastic in Portlethen Village
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. We work on joints between brick and frames, brickwork movement joints and concrete & block, and people most often call us about rigid filler in a joint that should flex and hard, crazed mastic that has stopped moving.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What external mastic looks like in Portlethen Village
Portlethen Village 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Portlethen station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Portlethen Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Portlethen Village is about 7 miles south of Aberdeen, in Aberdeen. Homes, rented property, offices and hotels in Portlethen Village can book us for external mastic.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Common questions in Portlethen Village
Does living near the coast affect external mastic in Portlethen Village?
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. Walls facing the sea are normally the first to need attention.
Do you work for landlords with property near Portlethen station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Do you work in Portlethen Village?
Yes. We’re based in Crawley and work across South East England, London and Scotland, Portlethen Village included.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Do you need external mastic in Portlethen Village?
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Common reasons people contact us include:
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
Managing a site like Portlethen Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
The process
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. For a place like Portlethen Village, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the joints are inspected and the access agreed.
- 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
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area

Advice
Why it’s worth doing now in Portlethen Village
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Around Portlethen Village, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
