Our Story

Since 2014, we’ve built a strong reputation across Southeastern and South Central Wisconsin for expert chimney and fireplace service. What began as Rock River Chimney & Fireplace has grown into something even bigger. In 2021, we expanded into sales and installation of wood-burning and gas appliances, and in 2022, we extended our service department to the Northwoods of Wisconsin and the Western Upper Peninsula. Today, we proudly serve our communities under our new name: Northern Lights Chimney & Hearth.

Our rebrand reflects our growth while staying true to what matters most—fire safety, reliable service, and exceptional customer care. Whether you need a chimney sweep, fireplace inspection, or a brand-new wood or gas appliance, we’re here to help with certified expertise and friendly support every step of the way.

At Northern Lights Chimney & Hearth, we bring knowledge, professionalism, and a passion for fire safety to every job. Our certified technicians stay up to date with the latest industry standards because we know fireplaces and chimneys are complex systems that require more than just a sweep and a ladder. We’re proud to have served thousands of happy homeowners, and we look forward to earning your trust too. Ready to schedule your next inspection or service? Call us at 920-390-4551 today!

On 5/6/2025 MonicA L. had this to say:
Incredible job! Rob did an inspection for a wood burning stove/fire that hadn't been used in years. He was on time, incredibly thorough and went above and beyond explaining about how to use it and what to look out for to signal the next cleaning. Will be using Rob again!!

On 11/15/2024 Dalton Uhing had this to say:
Deric was awesome! I was working from home, he did his thing quickly, cleanly and was extremely professional. Would and will be recommending this service!

On 9/5/2024 Hal B. had this to say:
Northern Lights Chimney (AKA) Rock River Chimney did a FABULOUS job inspecting or chimney. Unfortunately we have cracked and broken clay tiles which lead to our 80 year old fireplace being tagged as unsafe to use. Not what we hoped for, but when Rob explained what could and most likely would happen if we used the fireplace, we were so thankful for his honest assessment of our "slightly wierd" chimney. I would HIGHLY recommend these guys for any fireplace/ chimney work! They are fair and honest!!!

On 7/15/2024 Gary M. had this to say:
Showed up on time. Kept area clean, wore disposable booties over shoes. Thorough inspection with camera before sweep and after. Will definitely have out next time inspection/sweep is needed.
