You'd have to run all new cold air and hot air returns for a forced air furnace just not feasible.Get some one HVAC Boiler guy to bleed all air out of radiators, and baseboards.and stand by as helper. once system is bled of air locks will preform as designed and much quieter.Ya new boiler I put in for 6 plex was 7 grand.. 

I know someone that had his unlicensed helper go do that roof, and they fell off the building and broke their back.  

Thank you Colleen for sticking with with.We all need help getting started - thank you Bigger Pockets for the help you provide to us all - thank you to all the seminar speakers (good and bad).Who is your helper - mentor - coach - relative - your story is important.

No doubt this guy will perform top notch work but after respectfully grilling him on prices ($3/sq ft for click lock laminate flooring install - I can install 200sq ft per hour myself, 350sq ft per hour with a helper), $3/linear foot for baseboard - ehhh...chalk it up to post-Harvey inflation.I sent it out to estimate again, my drywaller/painter came back with a decent price and we're moving forward. 

Quality seems to be better at Home depot but Menards has a huge selection, and always have helpers available.

I had a contractor before who worked every Saturday for me for like 3 months because I was off Saturday’s and I was also his helper, go get this or that, cut me a stud, cut insulation, hold this or that. 

Try and partner with someone or be a helper to learn more.

Urethane or acyrlic grout has many of the benefits of epoxy grout (plus a few more) without the significant disadvantages.One of the chief extra benefits of premixed grout like the stuff I'm talking about is that you can put it in with a plastic putty knife, a grout sponge, a bucket of water, and your finger -- it's practically as easy and teachable to an unskilled helper as a basic craft project.

i regret giving home advisor my phone# cuz they have contractors on service requests YEARS after the fact, ie a remodel in nyc i submitted 2 years ago, they have contractors still calling me on that request, here in la county.what i gather is important is once decided on a contractor after inspecting work, etc is get their insurance certificate and call insurance to verify it is current and have the company assure me they are liable for anything that goes wrong while contractor is working on my property, etc also make sure they are using legal employees, ie what if they bring a helper that is not their employee but falls and get hurt, ditto what if they bring a next prospective client to show their work and they get hurt..so many bases to cover in today's litigious atmosphere!

This is what you get when you hire a self-performing "Jack of all trades" that has only two helpers... but at least I knew from the start that since this was first one, it would be kind of slow.5.
