Presta - 'If you make stuff that unscrews or unclips easily you don't end up having to redecorate just because you needed maintenance access.'
>40 years in the trade & project managment tell me that I nor my clients want to see screw caps or dirty shadow lines where the boxing meets the wall/ceiling, it looks cr*p. No need to re-decorate if it has to be removed, just cut the paint line in the corners with sharp knife & it'll go back nice & tidy (although you could easily re-caulk the corners & touch up the paint if required). In my picture we'd planned the pipe runs & left the filter on show which kept the boxing to the minimum size.
When the man came to repair my old water heater (a common occurrence) I doubt he would have wanted to prize off panels covering pipes if they were in his way, so I made a cover with two screws that I could remove in under a minute before he arrived, as I also did when I renewed the cartridge in the scale reducer every six months.
I doubt the boiler man would have wanted to crawl into a gap under the worktop between a cupboard and the boiler either, which is why I made the worktop lift off and the cupboard unhook off the wall without the use of any tools at all. When they're in place you can't tell they aren't fixed permanently.
There are two types of tradesmen, those who don't do the job properly, and those who would do the job properly if they didn't have to compete with the other lot.
Jobs tradesmen have done for me:
The gas board kept repeatedly bodging the repair to a jamming gas valve on my water heater. It took 16 years, a new water heater, several explosions, and a threat of legal action to get it repaired correctly.
A contractor walked all over the tiles on the lean to roof whilst fitting fascia and soffit. First he accused me of breaking them, and then he glued them all back together like a jigsaw puzzle using bath sealer. When he broke the landing window I had to stop him re-glazing it with polyfilla. I went up the ladder to repaint it afterwards, and it turned out that he had left all the old putty and glass in the rebate, and just glued the new pane over the top of it all with bath sealer. Then to humour me he had covered the whole lot with a layer of putty. He threw away the bathroom extractor fan vent with the old soffit, and then didn't fit a new one. When I complained that the hose was discharging into the loft he fitted a vent with no flange for the hose, so it was still filling the loft with damp. Next he fitted a louvered one so that all the flaps hang open and let the birds in. Fourth time lucky.
Plumber replaced my water main and threw the spoil back into the trench without compacting it, so it all subsided afterwards. He also left the electrical earth bonding wrongly connected.
After taking my watch back to the jeweller three times because the new battery kept stopping, I decided to make a key and unscrew the back of the watch myself. It turned out that the battery clip had been bent by someone who couldn't be bothered to unscrew it.
Hotpoint fitted washer dryer pump wrongly so that it kept cavitating.
Currys broke my TV trying to remove a circuit board without undoing the necessary screws.
LBS laced a wheel incorrectly.
LBS ruined all the screws on the bike by forcing them into threads choked with paint whilst fitting new frame.
Currys scratched a TV screen whilst they had it for repair.
The latest one was the washing machine repair man who deliberately slashed the windings on the fan motor whilst my back was turned.
