Draughty or Leaking Windows & Doors – these can be improved by making adjustments to the openers or locking mechanism, replacing hinges, gaskets & checking sealant for gaps around external frame.
Leaking Conservatory Roofs – leaks can be very deceiving even though water can be seen coming through one part of roof, it can actually be getting in from the opposite side.
To stop the leak all work needs to be completed on the outside.
Flashings would require checking, glazing panels may have slipped creating gaps or beads that have moved need re-positioning and fixing so it doesn’t happen again.
Using silicone to fix a seal on a conservatory roof will only give you a temporary fix as the hot summers and cold winters tend to create movement leaving silicone to split and then you’re back to square one with the leak.
This would need to be assessed on site to work out a plan of how to find & stop the leak.
