Positive
“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! -Dinah and Christie”
“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.”
