What the job involves on each surface
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.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
About our external mastic in Davidson's Mains
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We’re often asked to deal with joints with sealant missing in places and joints pointed up with cement by mistake, on brickwork movement joints, concrete & block and joints between brick and frames.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. In Davidson's Mains, those joints dry out over time and let water in behind the render or cladding.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Davidson's Mains questions
Does living near the coast affect external mastic in Davidson's Mains?
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 is work on the outside of a tenement in Davidson's Mains usually arranged?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
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 from the range available.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Looking after it afterwards
So the new joints stay in good condition:
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Davidson's Mains buildings and the weather
Davidson's Mains 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. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Homes close to St Columba's Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near South Gyle station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why it’s worth doing now in Davidson's Mains
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

- Subsidence or other structural problems

What we’re called out for in Davidson's Mains
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Look out for any of the following:
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
Managing a site like Craigroyston Community High School? Then larger buildings have long runs of movement joint that eventually need resealing.
