EXCELLENT Based on 496 reviews Michael Burke2025-08-18Trustindex verifies that the original source of the review is Google. Mace was excellent! He was courteous, knowledgeable and professional. Looking forward to working with him again. John Cervanyk (JADC55)2025-08-15Trustindex verifies that the original source of the review is Google. Many years ago, I tried to light a fire I in our fireplace and the room filled with smoke. I didn't know who to call, so we haven't had a fire in many years. This summer, I saw the Crown Up van in my neighborhood and called the number. Part of the cap had rusted through, and birds were nesting inside. It took about three weeks for a new cap to be manufactured. But when they came out, the measurements were off. Eli said he could make it work, but he wanted it to be right. Another three weeks, and the new cap fit perfectly. I'm very pleased with the work and I look forward to having fires again this winter.

Easy to schedule an appointment and Mace did a really excellent job on our three services. Will definitely be a return customer. Thank you, Mace! Meg Cosselman2025-08-11Trustindex verifies that the original source of the review is Google. Have used CrownUp twice now and had nothing but great experiences! Eli and Boaz both did a great job and would definitely use them again! Ashley Novak2025-08-10Trustindex verifies that the original source of the review is Google. UPDATE: Had Eli out to fix our cap and install a new damper. Him and his team were quick and went the extra step to let us know the manufacturer's notes on mantel material and clearance guidelines. Eli went above and beyond and we are set for any and all weather with the updates. Moses came out and inspected our fireplace/chimney. He was very professional, friendly, knowledgeable, and didn't try to oversell us on anything. Was able to make the fix needed to get us set up for winter and having fires at home. 10/10 recommend. And will call them back if any other fixes/cleanings are needed! James Prater2025-08-09Trustindex verifies that the original source of the review is Google.
