The reliable way to hire a tradesperson

Hi. I've recently had a new patio laid in natural sandstone. It's been down for about 3 months. Since the rains water is pooling in the centre and to one side. When the rain stops it does not take long long for the water to disappear. I believe the jointing was done with a porous compound. Is this because of poor workmanship or is this normal considering the rain we've had.

Hi guys, I’m adding a new bathroom which will need a new soil pipe connecting just from this room and terminating in the existing inspection chamber on the drive. Other runs into this chamber from the rest of the house have a standard vent above roof level. Question is, does this count as the same drainage ‘system’ and can I therefore use an internal stub stack, or do I need to fully vent? Many thanks

I'm planning to buy a 2020 semi, that has had an extension fitted across part of the rear in 2023. The builder appears to have concreted over 2 of the 3 periscope vents that ventilated the suspended concrete floor in the house. There are 3 vents at the front but just 1 in the corner of the rear. Should I avoid this house or cam this be fixed? Will it be causing issues under that floor?
