Yesterday we had our new hot water heater installed. Perfect 🥰! We have had Hartwig come out for several jobs. We have been remiss in complimenting them on their services. Each time has been a job well done….we will definitely call them again & refer them to others. Thank you.
I got lucky and had somebody here within an hour. The plumber was very personable and professional. He really saved my rear. I will continue to hire this outfit for future needs. Thank you!
Yesterday we had a hot water heater installed by Hartwig Plumbing & Heating. We were very pleased. Prior to installing they came out and had given us a written estimate on the work to be done. Yesterday a nice young man named Casey arrived at 7:30am & immediately went to work. Worked quickly, quietly & efficiently. Thanks Casey & Hartwig, you’re great!
Excellent service. I was referred to them by my friend. I couldn’t of been more pleased and at ease. Everyone I spoke with at Hartwig were kind and courteous. Thank you Todd, Mike and Matt for your help! Matt installed my furnace and answered all my questions. He did an awesome job! And I will recommend this company to everyone based on my great experience.
Jack is amazing! The old farm house we rent was not an easy job and he came out 3 separate times to get everything done, and done right. Quality workmanship and to top it off he is the nicest guy! Would recommend Hartwig (especially Jack!) to everyone. Thank you for all of your help!
