I got a lot of interest in the list of plumbers, so this is the list of people that were recommended to me along with the comments.
 
Thanks again, we live in a great neighborhood!
 

Plumbers

Jimmy LeDonne Tri-State Plumbing  412 621-5579 Shower repair last September highly satisfactory, fee not out of line.

We have had good experiences with Schubert Plumbing. I believe they have an office on Penn Ave.

These guys are good--reasonable,prompt, neat:   RDN Plumbing (412-462-1435).

Clair, Chris Personal Information: Mobile: 412-999-4834

Stahl is great. 

Have used Marty Kralik of M & D Plumbing for many years.  Has always done great work.  Call him at 412-741-2786.

We used B&F plumbing to install our gas line last summer (on a recommendation from someone else). They were able to come out pretty quickly and I thought they were reasonably priced although it was my first experience with a plumber. :-)

Martin Remodeling.  He has been doing some work for several folks on the list serve.  Great work, nice guy, cheap

We recommend Mark Seigle, 412-681-9091.  Can’t say how he compares on the basis if price.

Andy Stroje was great.  We really needed a toilet replaced -- one of the old ones with the cast iron tanks.  He brought his son and they did it in about an hour and half and it only cost $150ish for labor (we bought the toilet ourselves).  Excellent clean-up, very polite.  We have a couple leaks we're going to be tending to soon, and I'll be calling him again.  412-784-8191.

Call Golan Barak from Barak Plumbing 412-251-0301 or his cell at 412-295-2625.  He recently completed a project for a client of mine with rave reviews. 

I think John at Kangaroo plumbing fits your bill: 412-244-5775.  

OBHI 412-805-5602
