I had a really positive experience with this company. They came and they gave me a free inspection and gave me a lot of options as to what I can do. The technicians went over and beyond to explain everything that they were doing, so I was never left in the dark. Pricing was fair and everything was done in a timely manner. I also really appreciate how kind the technicians were. 10/10 recommended!

Thorough, no mess left behind, friendly, and quick. Another company tried to upsell me and charge me around $10,000 for a sweep and repair. Claus was no where near that and in my opinion the best chimney sweep company around. Highly recommend

Daniel did a great job and went above and beyond coming out on New Years to complete the job! I had an old fireplace that needed a special order replacement flue and cracks in the firebox needed to be repaired. Daniel & the whole Claus Chimney team was professional, communicative and friendly! Highly recommend.

Frequently Asked Questions

The biggest culprits are weather‑related erosion (rain, wind, and moisture), aging mortar joints, defective or missing flue liners, and the accumulation of creosote or debris. Over time, wood chips, snow, and temperature fluctuations can also crack or loosen bricks and lintels.
If you notice cracked or crumbling bricks, uneven or missing mortar, a damaged or missing flue liner, or any signs of water intrusion (stained or warped heat‑resistant boards), it’s time to call us. Even small issues can become major safety hazards if left unattended.
We start with a thorough inspection (including a smoke test and, if needed, a camera inspection). Next, we remove damaged sections, clean the interior, and install a new flue liner or repair mortar joints. Finally, we restore the exterior finish, re‑seal all seams, and perform a back‑draft test to ensure proper airflow and safety.
We recommend using a temporary, certified fireplace insert or venting system that meets local codes. While we’re working on the chimney, it’s safest to keep the fire off or use an alternative heat source to avoid smoke or carbon‑monoxide buildup.
The American Society of Heating, Refrigerating, and Air‑Conditioning Engineers (ASHRAE) recommends a professional inspection at least once a year, ideally before the heating season. Regular maintenance—cleaning, checking flue liners, and patching mortar—helps extend your chimney’s lifespan and keeps it safe.
