"Isabel and Ben were great! I had my chimney inspected and cleaned. I also had my dryer vent cleaned. They found very clogged and shoddy vent work in my crawl space for the dryer. They were able to fix, clean and get the duct work up to code same day. They showed me pictures and videos so I could understand the severity of the issue. I appreciate their clear communication throughout the entire process."

"Excellent service and price! This highly professional company communicated amazingly, did a fantastic job repairing the firebox in my fireplace, and replaced the chase cover on my chimney which was old a deteriorated. They provided a free inspection which gives piece of mind that everything is safe and secure. I will use Mile High Chimney again, and will highly recommend them to anyone looking for a great company to work with!"

Customers say: True professional

"I initially contacted Franco for a chimney inspection and cleaning. He discovered that our fireplace chimney needed a bit of work as expected, but more importantly the furnace chimney did not have a liner whatsoever. He came back the next day after gathering supplies to complete the job. He explained everything from start to finish and provided before and after photos of the work. I would absolutely recommend Franco to anyone."

Chimney Sweep FAQs, answered by experts

Some of the most common chimney problems include:

  • Creosote buildup

  • Chimney blockage

  • Deteriorating brickwork or stonework

  • Cracked chimney top

  • Damaged flashing

  • Flue liner damage or deterioration

  • Damaged chimney cap

If you suspect you have a chimney problem, contact a masonry contractor for an inspection. 

Yes, mineral spirits are flammable and may spontaneously combust at temperatures of 200 degrees F or more. Storing them in well-ventilated spaces and disposing of them the proper way are the best ways to prevent mineral spirits or anything contaminated with them, like towels and rags, from going up in smoke.

The timeline for smoke damage remediation can range from a single day to several months, depending on the extent of the damage, the size of the affected area, and the methods used. For minor damage, such as removing cigarette smoke odors from a single room, the process might take only one to two days and typically involves deep cleaning, painting, and sealing walls. Some methods, like ozone treatments, can take 24 to 48 hours, though multiple treatments may be necessary. More extensive smoke damage, such as from a house fire, can take three weeks or longer to clean and treat. If significant material restoration or replacement is needed, the timeline can extend to six to 12 months. A smoke damage restoration professional can provide a more accurate estimate for your specific situation.

All of the components of stucco are non-combustible, so the siding material won’t ignite or spread fire to the interior of your home. However, it also expands and contracts with changes in temperature, so it will crack from long exposure to heat. Eventually, fire will spread through those cracks. Still, stucco is one of the best siding materials for fire protection and can keep you and your family safe for an hour, on average.

Depending on who’s doing the estimating, about 22,000 to 25,000 chimney fires happen each year in the United States. Given the fact that millions of Americans have fireplaces (and chimneys), that means chimney fires aren’t exactly common—but they’re not rare, either. Since they’re so dangerous, it’s important to take precautions to prevent them.
