Workmanship

IMG_1956IMG_1955 IMG_1957

Three pictures from a roof in Bristol. The resident had lived there for 20 years. When they moved in they had a new roof put on, and the insides where totally ripped out and re designed. The first smell i had on entering the house was drains, followed by damp.

On entering the rear garden i noticed the rear of the Georgian property had been pebble dashed, on the far corner it had let go completely, one tap and the whole corner section would have fallen off. The area under picture one was also in a bad state all the way down. The resident had picked EWI mainly to cover it all up. I warned her the EWI would be trapping any damp in the wall, ventilation through the summer was imperative, i hope she was listening.

Originlly the 4” white trim in picture three wouldn’t have been there, it has just been installed as a top cover for the External wall insulation under the Green Deal. The occupant mentioned a wet patch on the floor outside her back door, that hadn’t been there before, so i climbed the scaffold for a look.

Picture one with the damp tile explains the damp patch. The tiles don’t overlap the guttering, (bad roof setup on install) there is also no felt until picture three, where you can see it’s perished. I could have taken a better shot of it but was wondering how the area on picture three was going to be made weather proof by the EWI installers, as their remit ends at the back of the 4” trim with a mastic joint. I looked at the junction between the top and bottom trim, what hope is there that that will do the job, none in my mind.

On picture one with the wet tile, the water was going behind the guttering and running over our trim and down onto the floor below, an improvement on the original setup, where it ran down the wall.

Back inside the house to show her photo one and two, she took me into the kitchen where big damp patches where evident at both ends of the room, one relates to picture one and the other to picture three. Stood there for a minute and the smell  of drains took over, part of the EWI remit is to extend all pipes by 100mm on the outside. On opening her sink cupboard i could see a push fit sink trap system, with all the joints twisted. Push fit connections rely on the pipes being straight, no side stresses or it will leak.

IMG_1962 Imagine if you can how you would connect the white pipe to the original grey exit pipe in the wall without stressing joints. Add in the fact the grey pipe is running uphill out of the wall, which means the system is holding more water than it should, thereby increasing the likelihood of leaks and its 50mm out in two directions. An impossible task. The smell of drains was so bad i wondered how wet the floor was under the unit. On studying the fittings dried on food particles told me it had been leaking for ages. In what was an immaculate house, shoddy workmanship had ruined her brand new kitchen walls and possibly the floor,and possibly upstairs was the same in the bathroom and bedroom. With picture three in mind, i’m unsure if the problem will be totally solved anytime soon without the help of a roofer. A Romanian fake EWI installer won’t be good enough. I say fake as in picture three is not to specification, that 100mm upright bead should be on the trim by centimetres at least. Aluminium expands and shrinks with the weather, in full sun by an alarming amount. It can split a mastic joint in a morning.

Years ago there wouldn’t have been any white trim, we would have extended the roof to cover the EWI and some. A dumbing down of the EWI trade to enable bus loads of untrained low paid foreigners to help the big company’s rinse as much money out of the system as possible before it gets closed, means house holders are not getting a good deal. The Green Deal is a bum deal for so many.
