Don't use Venmo if paying with a credit card. Some treat it as a cash advance, and charge 30 %. That's not Jeremy's fault. I would definitely hire him again. He did all the work alone, and in some serious heat. He really cares about his customers, and it shows. I can't recommend him higher.

Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.
