Solution 5 you could also buy a normal gutter cut it to the size you need and run it under the hole dripping the water and past the balcony.
Condensation dripping from gutter.
If you stop air getting to the gutter you re problem is also solved a bit like insulating cold water pipes prevents condensate forming.
I d stick pu foam to the gutter with pu adhesive the fast set type to completely encase it and pack any remaining void with insulation and see how it goes.
Unless you regularly clean them out your gutters can quickly fill up with leaf litter and debris.
Picture a cloud of moisture floating overhead between the rafters.
Clogs are one of the most common causes of leaky gutters.
That excess moisture ends up as drops of condensation on the roof.
Warm wet air rises and meets the cold roof and cools.
That puts it about three inches above any water or debris.
Along that side of the conservatory is a rectangular lead gutter about 10 wide flat base and 3 4 metres long.
In most cases you ll notice the problem as soon as you get a close look in your gutters.
It is internal to the conservatory.
It could be that the gutters have small holes or the fascia boards are starting to pull away a little and that is where the leak is coming from.
Luckily clogged gutters and downspouts are quite easy to spot.
In cold weather the differential air temperature between inside and outside the conservatory is such that water condenses onto the lead at such a rate that it drips down the wall causing large patches of damp that will last throughout the colder months.
Essentially condensation occurs at night when the temperature inside a building is warmer than outside.
My thought is that if the water or debris is that high the drain placement is pretty far down on the list of problems you have.
You might get condensation on the underside of a box gutter but not normally further down a dry lined wall there would also be some different pattern staining between penetrating moisture and condensation is there a cavity tray in the external wall above the conservatory.
Drill a hole in the part of the gutter you want the water to come out.
Attach it to the wall using clips or gutter mounts.
I always aim to have the condensate drain pipe come out just under the drip edge and extend an inch into the gutter.
