Damp conservatory floor, big worry :-(

:-( can anyone actually help with the question about the floor level seal?

Well, personally, I would phone or call into a conservatory supplier and try to pick their brains for free.:)

If the water has come from a leak I don't see the point in applying a seal to the floor. Cure the leak and let it dry out fully - have you ever had any problems with damp in the past in the conservatory?

It is a house we bought a few months ago and are renovating. The conservatory is over 10 years old and I don't know who made it.

I think the water is coming in under the seal around the floor and wall.

I was planning to reseal this but wondered if it is common to have a sillicon type seal round the base of the conservatory between the UPVC walls and the concrete floor.

One day we will replace the conservatory but right now I can't afford to with all the other work we are doing to the house.

Is it just coming in between the conservatory walls and the conservatory floor, or between the house wall and the conservatory floor as well? If its just a pvc frame set on the concrete slab I don't see how else you can seal it other than silicone. The way its been built is not really the correct way to build it, if I'm interpreting things correctly. I would be interested to know where the damp-proof membrane is and how it is detailed at the floor edges, but you almost certainly won't be able to see it. You may also benefit if you applied some waterfproofing liquid or compound to the exposed edges of the slab externally, but I don't really know for sure how your conservatory has been built.

Think it is just between the slab and the conservatory walls. It is a pain as there is a 20cm gap between the conservatory and the neighbours wall. This makes it near impossible to do anything externally to fix the problem!

I am planning to get some lead flashing installed between the conervatory roof and the wall covering the 20cm gap so water isn't just running down the side of the conservatory with no where to go!

Not the best picture but might help people understand the type of conservatory!

I will lift the vinyl floor this weekend and see if it starts to dry out or not!

This sounds like the exact problem I'm having, your conservatory looks remarkably similar too...

I only noticed the extent of the damp floor-ness this morning. I have furniture in there, including some soft furnishings, and none of that is damp, the walls aren't damp and there's no drips/leaks from the ceiling.

I was wondering if it was condensation somehow. The floor in there is always cold (no foundations) and I guessed that as the sun rises it will start to heat the air in the conservatory and cause some condesation to form on the cold floor. Is this likely?

I really don't want to rip up the floor as it's quite nice and we don't want to change it. Plus it sounds like hard (and expensive) work
