Henthorn Plumbing

They've done quite a bit of work for me and Matt is just very responsive, very knowledgeable. He works quickly and he will handle any problem.

I did my tankless unit research after considering Noritz, Rinnai and Navien brands for a tankless water heater. Based on 98% efficiency, primary and secondary heat exchangers being all stainless steel, internal recirculation pump to reduce cold water sandwich effect and Navien being based in Irvine, CA (overnight parts) vs being located on east coast if I ever needed a part under warranty, selected them as the tankless supplier
Then began the licensed plumber research and arduous quote process, after evaluating a number of plumbers who came out but some never quoted: Payless Water Heaters, BG Plumbing, Freitas Plumbing, Counsil Plumbing, Cool's Custom, On Demand Water Heaters (never quoted after viewing project), Just Tankless (never quoted or responded after viewing project), and many others selected Henthorn Plumbing. 
Most plumbers for tankless install will aim to bill you for the job for worst case scenario which equates to $300 per hour if you do the math (for two day install) this is to protect them just in case problems arise so you will see quotes vary largely from $3.8K-5K-10K.  I specifically wanted a plumber that would charge time + materials and stay on target vs charge for the worse case and Matt Henthorn was the plumber that could do exactly what I wanted and he stayed on target with install in 2 days as estimated.

Project was to run a dedicated 35ft x 1" galvanized steel gas line from meter mounted to strut, strapped every 7' with sediment trap, pressure tested prior to connection to Navien NPE-210A tankless water heater installed over plywood (brace sheet rock) meeting manufacturer clearance requirements, 2" schedule 40 PVC intake and exhaust vents separated 12", removed old washer stand-pipe, installed new PVC standpipe, sanitary tee, cleanout, new laundry box with water hammer suppressors, condensate neutralizer and scale inhibitor along with service valves, new gas dryer hookup and flex, install new brass hose bib.  Also installed a new figure 5, sanitary tee to support both new future laundry vanity sink and existing bathroom sink. I patched the sheetrock myself so he could finish the install.

Matt completed full install in 2 days, everything worked as it should, now have endless hot water, I will call him back to finish vanity sink hookup once I have it and countertop installed. His time and labor quote was very competitive and no corners were cut from project scope that I drafted.
Matt demonstrated journeyman qualities of integrity, honesty, cool head - nothing seem to phase him if complications arose, he is CA C36 licensed, bonded with workers compensation (he had one helper to help with gas line cutting and bracing) and does all work according to city code. He is also personable, positive attitude involves you in the decision making process and options. 
I am wholeheartedly recommending him for your tankless water heater, gas line, water hookup, drain and any other plumbing needs. 5 stars

Matt Henthorn is not new to us. We have used his services before and experienced the same professionalism this time. Matt is responsive to calls for help and is flexible and prompt for his appointments. Matt the drainfixed and the toilets ordered quickly. After picking up the order Matt returned and neatly installed the toilets. Next came the small cleanup and attention to detail. Matt is very respectful of property leaving everything spotless. It is great to never have surprises in Matt's bids and time line.
