About our external mastic in Kenmore
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you are dealing with joints with sealant missing in places and hard, crazed mastic that has stopped moving, we can help.
Outside joints can only be sealed when they’re dry, so work in Kenmore depends on the weather. Tell us how to reach each wall, gutter and roofline.
Every job is covered by a one-year guarantee.

FAQs for Kenmore
Is there a guarantee on external mastic in Kenmore?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Kenmore within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before any work starts, matched as closely as the range allows.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them.
What we’re called out for in Kenmore
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
These are the problems we’re asked about most:
- Panel joints letting water in
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
- Sealant pulling away from one side of the joint
For jobs in and around Kenmore, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before you book
- How the surfaces are prepared before sealing
- The length of the guarantee
- How much experience the applicator has
- Whether the sealant suits the joint
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the building. Somewhere like Kenmore may be a longer drive, and the journey is planned ahead. 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Mention any tricky access

Walls and rooflines in Kenmore
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Kenmore, as everywhere, external mastic is only as good as the preparation behind it.

DIY sealant or a professional job?
What a professional job adds is preparation and the right 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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep soil, plants and ivy away from the joints
- Fix overflowing gutters above sealed joints
- Get split or bare joints resealed while the damage is small
- Tell anyone working on the walls about the movement joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
