"Our chimney and fireplace had not been used since at least 2018, so we needed someone to check it out prior to using it. They both cleaned the chimney and inspected it for any issues. The issues they did find they brought photos of and explained to us. They were polite and kind and respectful of keeping our home clean while working. We would recommend them to anyone else who needs their chimney worked on or cleaned."

"The repointing work was generally done well. Old mortar and bricks were removed and new bricks were installed. The craftsmanship was excellent. However, the color of the mortar used differed from that in the rest of the brickwork, so at present it stands out. Sixpenny said to wait a period and then re-evaluate whether any change should be made. I would rate this as an "A" but for the color difference in the mortar that was not expected. The chimney cap work was done well."

"Mr. Thomas, Dwight and crew performed the level 2 chimney inspection (only/no sweep requested) and repaired the brick/masonry of the chimney, including repacing the flue liner and repair of the chimney box. They provided literature, kept me highly informed of status, arrival, appointments, and work progress. They also completed a beautiful job on my neighbor's chimney rebuild/replace. The work looks really great and it is apparent that Mr. Thomas, Dwight, and the masonry crew take pride in their workmanship and quality. The job was completed within 2 days and so far, everything is looks fantastic. Waiting for a cool day to crank up the fireplace. They also provided a professional lamination card and pen for reminders of next year's chimney sweep. I only slightly hit the value as I would have loved the inspection price to be part of the repair and the receipt, but overall, great experience, great A+ rating on BBB and both licensed and bonded. Obtained via Angi/home advisor"

"I've used American Professional several times at various houses I've lived in or owned. They are an honest and professional company that does good work and stands behind it. I recently got them to give me an estimate on rebuilding the top portion of a chimney that needs brickwork. They inspected the chimney, told me it was safe to use, and gave me a very reasonable estimate for the chimney rebuild, saying that it can wait until spring if I wish. From my experience, they will do everything they can to satisfy the customer, whether it's a simple chimney cleaning or custom work. This is the best chimney company in the DC area by far."

"We initially booked a chimney sweep, because smoke was getting into the house. When the cleaner showed up, he inspected the chimney and found that a cleaning was not necessary and didn't charge for it, and instead walked us through steps to talk to better operate the chimney. Since then, smoke has not been an issue."

Chimney Sweep FAQs, answered by experts

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.

In many cases, homeowners insurance covers smoke damage remediation, but coverage depends on the cause of the damage and the specifics of your policy. Typically, damage from a house fire, wildfire, or even a fire in a neighboring home is covered. However, damage from cigarette smoke is generally not covered.

Before filing a claim, review your policy to understand what is covered, such as restoration costs, replacement of damaged items, and temporary relocation. It's crucial to document all damage thoroughly, including to furniture and personal belongings. Contact your insurance provider promptly to start the claim process and get an evaluation before hiring professionals. Your insurer may also provide a list of approved smoke remediation companies to streamline the process.

Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity. The combination can cause serious injury from electrical shock and worsen the situation by adding fuel to the fire. Baking powder is also not an option as it's also highly flammable. 

Costs depend on stone type, surface condition, labor, and whether sealing or deep cleaning is required.

Call 911 immediately. If you have a fire extinguisher or fire blanket near the laundry room, you can attempt to extinguish the fire, but don’t open or touch the dryer. If you can’t put the fire out, evacuate yourself, your family, and your pets from the house, closing the laundry room door behind you. Turn off the electricity to your home via the outside fuse box, then wait for the fire department. After a dryer fire, have your home’s electrical system inspected to make sure there isn’t any damage.
