We celebrated our Lead Technician Zac's workiversary last week, and we thought it was the perfect excuse to turn the spotlight on him. In this issue, we’re sharing a special 'Insider Scoop' Q&A so you can get to know the person taking care of your tech a little better! Q: What is the one tool you absolutely could not do your job without? A: A tiny crescent wrench I keep in my pocket. It's fully adjustable so I can use it on EVERYTHING, water lines, taking apart faucets and shower heads, putting new blades on our saw, you name it! Q: What is your favorite type of job to work on? A: Trim outs (that's when we install all the fixtures in a bathroom) because you can make it look all fancy and nice Q: What's your go-to snack food? A: I'm a gummy kind of guy. Sometimes during work we'll stop at 7-11 and Will will get food but I'll just pick up a bag of gummies Q: What is your favorite local restaurant? A: It's not really local since it's a chain, but my wife and I love the half apps at Applebees. I'm open to suggestions if you have any though! Q: If you could travel anywhere in the world, where would you go? A: I'd have to say Sweden for the snow, I love snowboarding Q: If you were an animal, which one would you want to be? A: A Mouse. No further context needed. Maybe a slight upgrade to rat Q: What's the weirdest gift you've ever received? A: Ever since becoming a plumber, the amount of plunger-related gifts is insane. I've got at least 3 mini-plungers now. Here’s to many more years of Zac helping things run smoothly at JAD!

Trivia on Tap: Did you know that Albert Einstein is famously quoted saying: "If I would be a young man again and had to decide how to make my living, I would not try to become a scientist or scholar or teacher. I would rather choose to be a plumber or a peddler in the hope to find that modest degree of independence still available under present circumstances." In the middle of the McCarthy era, Einstein felt that scientists and scholars faced unwarranted scrutiny and admired the freedom professions such as plumbers and peddlers retained. His letter to the newspaper explaining just that, resulted in him receiving an honorary membership to the Chicago Plumbers Union!  Announcements: This area is expected to get snow this weekend so make sure you are prepared! If you notice anything out of the ordinary with your plumbing or gas fitting equipment, let us know ASAP so we can get to it before the storm!

Recent Reviews: JAD Plumbing & Gas Fitting is committed to quality service, clear communication with clients, and convenient scheduling! But you don't have to take OUR word for it! Check out these reviews: "James responded to my request, immediately. He kept communications flowing and scheduled Zach to provide service. Zach was very friendly, professional, thorough, and informative. Great to work with. He quickly identified the issue and repaired it equally as fast. James also provided recommendations for water remediation and drywall repair. This is my 4th service call with them (different issues each time), and I will continue to call ONLY them for my plumbing needs, " --Y. V. Godfrey "This company did a fantastic job correcting my sewer issue. Same day service, very through in finding the problem, kept me informed as to what they were doing. Very polite and respectful, cleaned up after themselves. We will never call another plumbing company, " --Helen Cervenka "JAD Plumbing does good work! They are very responsive and professional. From initial contact to giving cost estimate, to being on time for the appointment and being able to resolve the issue. It was a pleasure doing business with them. I will definitely call them again if I get another plumbing issue, " --Kipps Pengosro Thank you Y. V., Helen, and Kipps for supporting us!

Recent Review: Check out this stellar google review! Thanks for the kind words Tracy! "I can’t say enough great things about James A. Douglas Plumbing and Gas Fitting LLC. The customer service, communication and the service provided was top notch. I had called 2 other plumbers prior to speaking to Mr. Douglas. Not only did they quote me twice as much but if they weren’t pushy they came across as not interested in the project. We have an older home and the shower was constantly dripping and had low pressure when in use. It was an easy fix Mr. Douglas’s team and I would definitely hire them again," Announcements: If you haven't already, make sure to follow us on your preferred social media platform for more helpful tips and videos!
