"After finding out that our wood stove couldnâ t be installed due to an issue with the width of our existing chimney & the proposed liner, Honeycutt Chimney Sweep was recommended to us. Not only did Dustin fit us in quickly, but he also patiently explained our options, helped us pick the best choice for our current situation, and came back less than a week later to complete the proposed work. Everyone we interacted with was kind, courteous, and did the job quickly & correctly. I would recommend them to friends & family without hesitation!"

"Richard was extremely responsive, making a trip to the house prior to providing an estimate. His crew showed up on time and worked all day. My job took three days, and they left the house neat and tidy at the end of each day's work. They repaired my fireplace chimney, the fireplace chimney liner, and the utility chimney. Their experience and craftsmanship was on display in the quality of their work. The crew chief, Valentin, was outstanding with great communication and attention to detail. You only want to repair your chimneys once, and if you hire Chimney Discounters, rest assured the job will be done well."

"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

Neglecting to clean your chimney can lead to serious safety hazards. A primary risk is the buildup of creosote, a highly flammable substance that can ignite and cause a dangerous chimney fire. This buildup can also create blockages in the flue, resulting in poor venting of smoke, soot, and toxic gases like carbon monoxide, which can then enter your home and create dangerously poor indoor air quality. Additionally, creosote is acidic and can damage the chimney's mortar and metal components over time, potentially allowing smoke to leak into your house. To prevent these issues, it is essential to schedule an annual chimney cleaning with a professional.

To get rid of the smoke smell in a microwave, scrape off any burnt food residue and throw it away. Next, warm a cup of water in a microwave-safe container for three minutes. Then, dip a microfiber cloth into a mixture of water and a couple of drops of dish soap and wipe down the inside of the microwave. Dry the inside of the microwave with a fresh cloth and let everything air out for three hours.

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

Smoke damage will not go away on its own, but with professional remediation and restoration, you can return your home to its original condition after a fire. Trained smoke restoration professionals can eliminate smoke damage, which can affect areas of your home that are hard to see or access, and restore or replace smoke-damaged materials.

Ozone smoke removal uses an ozone generator to eliminate stubborn odors from sources like house fires, wildfires, or cigarette smoke. Ozone (O3) is a highly reactive, unstable gas that neutralizes odors by oxidizing the organic compounds it comes into contact with. During this oxidation process, ozone "donates" its extra oxygen molecule to the smoke particles, effectively eliminating their smell, with oxygen being the primary byproduct. While ozone can be effective for removing smoke smells from building materials and belongings like wood furniture, this treatment is best left to a professional, as improper use of an ozone generator can be dangerous to your health.
