A few months ago i had my garage converted into additional living space by a specialist conversion firm, as part of the job I paid them for a rubberized roof covering on the existing flat roof.
Before they got started i had a builder round to replace the failed concrete lintel above the garage door with a steel one, he rebuilt the single skin 9 inch parapet wall above the lintel and put the old coping stones back on top.
A few weeks after the garage was done we started to notice drips of water on the inside of the window forming a pool on the window sil.
The conversion firm have sent 3 different staff out to look at it. The first one thought that water running down the wall was getting in at the lintel (which is covered by a pvc fascia) and he put loads of sealant around the PVC. The 2nd thought the problem was the roof he thought water was getting in around the flashing so he sent for the roofer.
The roofer was annoyed and adamant that no water was getting in at the flashings and told the other half that water was geting in through the coping stones and down the cavity and it was the fault of the builder who did that job for not fitting a cavity drip tray. The company then gave me a quote of £1k for taking down the parapet, fitting a drip tray and re doing the bricks.
When i pointed out that the wall was single skin with no cavity at first they said maybe they should put some lead under the copings then they came out and painted some grey sealant type stuff all over the back of the bricks, the top of the coping and along the points where the rubber joins the bricks.
We had hoped that this would work but yesterday when it rained we had pools of water again however they had moved from the middle of the window to the right had side at the lowest point of the parapet.
Please could you have a look at the pictures and let me know what you would tackle first. Chances are i will now get someone else to sort out the problem as i've lost faith in the original firm and they subcontract everything so whatever i get done will have a hefty mark up on it.
The very last photo is looking towards the neighbors side, it is attached to ours and he has no issues with leaks.
