Coating balconies and Juliet balconies properly

A balcony floor being checked for correct falls towards a drainage outlet before coating

Balconies sit fully exposed to rain, sun and, near the coast, salt-laden air, while carrying standing water after every downpour if the drainage detail is even slightly wrong. A Juliet balcony's slim glazed front looks simple but often hides a steel sub-frame that needs just as much attention as the visible rail.

Drainage and standing water

A balcony floor that does not shed water properly holds moisture against its coating far longer than a vertical surface ever would, which accelerates failure at the floor-to-upstand junction in particular. We check the fall and drainage points before assuming the coating alone will solve a wet balcony's problems.

The hidden steelwork behind a Juliet balcony

Many Juliet balconies are a glazed panel held by a steel sub-frame fixed into the building fabric, and that steelwork corrodes exactly like an external railing would if it is not maintained, even though it is barely visible behind the glass.

Coastal balcony blocks and salt exposure

Balconies on seafront blocks take a heavier dose of airborne salt than almost any other part of the building, and a coating specified for an inland property often underperforms here. We specify with that exposure in mind rather than using a single standard system across a whole development.

Working on occupied balconies

Balcony work usually means being on or immediately outside someone's home, so we agree timing, access and how furniture or planting will be moved and protected before a single tool comes out, rather than leaving residents to work around us.

Questions we are asked about this

Do Juliet balconies need painting if they are mostly glass?

Often yes, because the steel sub-frame holding the glass corrodes over time even though it is largely hidden. We would check the frame's condition rather than assuming glass means nothing needs attention.

Why does our balcony floor coating keep failing near the edge?

That is usually the floor-to-upstand junction, which holds water longest if the falls are not quite right. Addressing the drainage is often as important as the coating itself in stopping repeat failure.

How do you manage access to lots of individual balconies?

We agree a schedule flat by flat with the managing agent or residents, so everyone knows which day their balcony will be worked on and when they can move furniture back.

Painting in autumnAutumn exterior painting works, provided the programme respects shorter days and slower drying rather than fighting them.Winter working limitsWinter is for repair and preparation outside, not for coating, and a realistic programme treats the two separately.What to send for a quoteA clear set of photographs and honest notes on condition gets you a faster, more accurate quote.Handling scope changesA scope change is only ever actioned once it has been described and agreed in writing.

Balcony coating only holds up if drainage and any hidden steelwork are checked alongside the visible surface.
