Quality Recording Booths

I had a similar experience to the post below mine. I bought a fairly expensive booth from Jake Davis in April 2014. I bought a double wall 6×8 booth and asked multiple times about the isolation the booth would provide. I was assured that I would get the isolation I needed but could add quiet rock 510 drywall for an extra 400 $ and surely get what I was looking for.
The booth was 3 weeks late from the original install date so it took about 1.5 months for my booth to be built. I kept inquiring about progress pictures but didn’t get any until the night before the booth was delivered (when it was probably built).
When the booth was installed I walked inside, shut the door, and could hear everything that was going on outside of it. I asked Jake why and he told me it probably needed to be sealed. I was pretty unhappy but the booth was already there and I was forced to sign paperwork that said I was 100% happy, pay for the rest of the booth, and was told that he would come back and seal it for me.
After Jake left I realized he had forgotten to install a power outlet that we had agreed on. I also found out that the quiet rock 510 I paid extra for was actually quiet rock ez snap and that it was glued to the wall in squares and not mounted to studs (rendering it pretty much useless). The more I examined the booth I realized it had no science behind it at all. I had basically paid almost 4000 dollars for 4 painted walls with some foam on it.
When I called Jake about it he told me «there’s soundproofing around the whole booth!» confusing foam absorption with soundproofing materials. That’s when I realized this guy had no idea what he was doing. After some research I found out his other business is quality home improvements, which is probably his original business before he found out he could fool people into thinking he knows how to make a recording booth.
So he did come back. But not for 2 weeks (no power so I couldn’t use it for those 2 weeks). He chuckled at me when I told him I was losing business because of it. I think he assumed I was a hobbyist and not a professional. But that’s ok. He was pretty nice about it all.
I asked for my money back for the 400 $ quiet rock that he installed improperly and he agreed to, but he said I had to wait 3 months for the refund. So 3 months rolls around and he «doesn’t have the money. I can’t give you money I don’t have.» I got a little bit upset and he showed his true colors by ridiculing me and acting extremely unprofessional.
A day later he told me he felt bad and if I gave him some time he would get me the 400 but could give me 100 dollars that day. He PayPal’d me $ 100 but made me pay for the fees so I only got 92 $. Whatever.
That was 6 months ago. He hasn’t returned a phone call or text message since then. This guy doesn’t know what he’s doing, is a horrible businessman and runs a shady business. To be avoided at all costs.
