Interior Painting in Llanishen
Llanishen’s post-war construction used plasterboard throughout rather than lime plaster. The primary interior challenge is hairline cracking at plasterboard joint lines.
Plasterboard Joint Assessment
Cracks along joint lines are assessed before any painting begins. Active movement is identified and logged at quote stage.
On older boards (50+ years), joints have moved repeatedly and may need a skim before painting will hold without recracking.
Joint Stabilisation
Hairline cracks are scrimmed and sealed before painting. Filler alone re-cracks where joints have moved.
Skim Coat Option
For heavily cracked ceilings, a skim coat over the joint line is the most durable solution. We advise on this during the site visit.
Large Property Coordination
A full interior project across all floors and rooms is planned as one composition. We handle interior painting for four and five-bedroom Llanishen detacheds.


The plasterboard joint issue is common in properties of this age. Proper repair eliminates it.
Exterior Painting in Llanishen
The 1960s–1970s detached properties on Ty Glas Road have garage doors and integral garage sections. The render on the garage panel often has a different mix from the main house render if the garage was added later.


Garage Panel Assessment
Junction cracks between garage and house render are identified and filled with flexible sealant before painting. These junctions crack if not sealed first.
Brick and Render Mix
Many properties have both brick and render on the same elevation. Different paint systems ensure durability on each surface.
Render Crack Repair
Any cracking is filled and stabilised before painting. We handle exterior painting for all property types in Llanishen.
Fascias and Soffits
Timber fascias and soffits are stripped and refinished in gloss. Garage doors and panels are painted as part of the exterior project.
Llanishen properties generally do not require scaffolding. Ladder access is typically sufficient for most properties.
