It's literally the most important part of your system or your home.
The components are one thing, but without the right assembly, you may as well have flushed your money down the toilet.
This photo shows exactly what I'm talking about. From an install perspective, all the extra time taken to lay, cut, and measure the outlay properly is often overlooked by the tradesman, who doesn't care as "the boss pays me shit so I don't do my best". Terrible attitude, but something we saw over and over with other companies. This job took another 4 hours to get perfect, but look at the results, it couldn't be done any other way.
The reason why we only have a couple of in-house installers is, you just can't find that many tradesmen out there who can carry out the quality of work we strive for.
