Arlington, MA. Friendly & professional. Upon arrival, our guy Matt reviewed exactly what was being done and he made sure to discuss the price that was originally quoted over the phone. Matt was honest with the work that needs to be done on top of our chimney (aligned with a quote from a different company last year). Matt took pics from the roof and made a few, much needed recommendations. Most importantly, he was CLEAN and didn’t leave a speck of dust behind. 2 chimneys took him about an hour. You may want to wait until the slower months for a little better price but we’re very happy with the service. This is the 2nd time Master Chimney has come to the house. We highly recommend Master Chimney and will have them back again next year!

I have used Master Chimney Sweepers for a number of years and can say that they are professional, courteous, friendly, and on time. The technician took time to educate us on the proper methods to manage a fire both in our fireplace and woodstove. I would certainly recommend Master Chimney Sweepers to everyone needing fireplace and / or woodstove services.
Frequently Asked Questions About Master Chimney Sweepers
Why is it important to inspect and clean oil chimney flues and gas chimney flues annually?
The chimney flue is the passageway for toxic gases to escape out of your home. Cracks, holes, or obstructions in a chimney flue can cause dangerous carbon monoxide fumes, or soot, to leak into your home. This is why the National Fire Protection Association recommends that oil and gas furnace flues are inspected yearly to ensure proper draft, venting of soot & fumes, and, to guarantee that there is not an obstruction in the flue.
What does a chimney sweep determine from inspecting my chimney? Is this inspection necessary?
To understand what is getting inspected in your chimney, you need to understand what is happening in your chimney. For starters, your furnace is exhausted into your chimney. If this passageway becomes obstructed with debris, carbon monoxide and soot will be exhausted into your home, which creates a very dangerous situation for you and your family.
The debris that accumulates in your chimney is from the ongoing breakdown and decay of the inside passageway from your furnace chimney. This passageway is constructed of terracotta tiles that form a column to exhaust the gases. Over time, the exhaust, which is laced with sulfur and water, attacks the skin of these terracotta tiles, and this begins an ongoing shedding process. The shedding debris then begins to accumulate at the base of the chimney or in the turns of the chimney column. This shedding and accumulation process requires yearly monitoring by a chimney technician. Failure to do so puts your furnace chimney, and your home, at risk of a carbon monoxide blockage.
Also, as your chimney ages, its 5/8” thick liner can become so decayed that partial or full sections of tile can collapse and cause obstructions and holes or cracks in the exhaust column. This allows gases to leak into your home’s living quarters. At this point, you may need to have the liner replaced with stainless steel. Your chimney technician monitors this aging process, protecting your chimney, your home, and your family.
Finally, if your chimney was built prior to 1900, there is no column of tile. This is called an unlined chimney and should be relined with a stainless-steel chimney liner.
At what age does a chimney begin to deteriorate?
Our technicians have encountered flaking tiles and misaligned flue tiles in homes as young as ten years old.
What do I do if my chimney is smoking or smells?
Smelly fireplaces are a common occurrence when the weather is damp and humid, and a low-pressure system has moved into the region. These problems tend to occur in the late fall and early spring because the temperature difference between the outside air and inside air is not as great as it is in the winter.
Some solutions to this problem are:
Making sure that your chimney is clean.
Try to use your home’s windows to reverse the pressure coming down the chimney. The best windows to use are the ones on the windy side of the home. Basement windows are also good because they are loaded with pressure. You should crack the window a quarter of an inch, and then give it several hours to see if it makes a difference. Continue to try windows until you find the one that works best. Basically, you are relieving the pressure in your home, while bringing in fresh air.
For a guaranteed solution to these problems, you can have an Enervex chimney fan installed on your chimney.
What do I do if my basement fireplace is smoking?
Basement fireplaces often get smoky when the upstairs fireplace is being used. This problem is most common for homes built with exterior chimneys after the 1960s – especially in raised ranch, cape, and colonial-style homes.
This smokiness occurs when the fireplace flue in the basement is vacuuming smoke from on top of the chimney and bringing it down to the basement.
To alleviate this problem, make sure that your basement fireplace damper is closed. The best solution is to crack a window in the basement (about a quarter of an inch) when you use your upstairs fireplace. Basically, the upstairs fireplace starts searching for ‘makeup air’ as soon as you open the damper. If the basement window is cracked, the upstairs fireplace will hopefully get its ‘make-up air’ through that window, rather than the leaky damper in the basement. If you are not planning on using the fireplace in the basement, you can put a temporary seal on the top to stop the smoke from coming down the chimney and into the room.
Keep in mind that sealing dampers work about 50% of the time but are not guaranteed to solve this problem. Chimney caps can often make this problem worse. Another good option is to extend the upstairs fireplace flue tile on the top of the chimney another 12-24″.
Why is it important to inspect and clean oil and gas chimney flues annually?
Annual inspection and cleaning ensure toxic gases like carbon monoxide safely vent out of your home, preventing dangerous leaks caused by cracks or obstructions in the chimney flue.
What is involved in a chimney inspection and why is it necessary?
A chimney inspection checks for debris build-up, cracks, and decay in terracotta tiles that could lead to carbon monoxide leaks, ensuring your chimney functions safely and effectively.
At what age does a chimney typically begin to deteriorate?
Technicians have observed chimney tile flaking and misalignment in homes as young as ten years old, indicating the importance of early and regular inspections.
What should I do if my chimney is smoking or emitting unpleasant smells?
Clean your chimney regularly, try cracking windows on the windy side of your home to balance pressure, or consider installing an Enervex chimney fan for a guaranteed solution.
How can I resolve smoke coming from my basement fireplace when using the upstairs fireplace?
Close the basement fireplace damper and crack a basement window slightly to provide makeup air for the upstairs fireplace, reducing smoke backflow into the basement.
