Owned and Operated by Firefighters

Smoke Alert was established in 2010 and we are very proud of the fact that fire safety is our top priority. Our mission is to save lives by providing superior service at reasonable prices. Our main services are chimney sweeping and dryer vent cleaning, but with every service we also offer a free home fire safety check where we check the smoke alarms, carbon monoxide alarms, and fire extinguishers. If anything is found to be defective or not present we can install new ones for about the same price you can buy them at the store.


There are a lot of companies that say they do chimney sweeping but are not properly insured or certified to do the work. They will advertise - full inspection and sweeping of masonry chimneys. To be properly insured requires far more than a standard liability policy in fact they can cost upwards of 8,000 even for a small policy not including workers' comp. That dollar company will show up with some sort of shop vac() vs a professional chimney vac(,200). They run a high risk of getting hazardous soot in your home using a system that is not specifically designed for chimneys. On top of that in order to make up for their reduced price you can expect to be told a lot of scary things about your chimney that will require a lot of work if it needs it or not. We go behind companies like this all the time to clean up their mess and get the job done right. I would implore you to look at reviews online and you will see the caliber or work we do vs a cut rate company.

Frequently asked questions

  • how can we clean dirty vents?

    Unfortunately there are a lot of companies out there that "do" dryer vent cleaning but do not have the proper training or experience. All dryer vents are cleaned with a professional Brush system and a 400 CFM HEPA VACUUM. We first check out the the vent and get an initial air flow reading. Then we hookup our HEPA VAC inside. We send our brush through the vent and take it all the way from one end to the other so you know, for sure, it made it all the way though your dryer vent system. Do not let someone clean your vent from the outside with a compressed air tool on a residential dryer vent, it just will not get the job done. DO NOT let someone come in with a SHOP VAC and some tools you can buy at Home Depot for . In order to clean dryer vents properly you must use a professional brush system along with a HEPA VACUUM, PERIOD! If you are already having trouble drying your clothes you need to get it done ASAP.

  • are dirty vents a fire hazard?

    A clogged dryer vent will certainly cause a dryer to run hotter and increase the chance that something could catch fire. A dirty vent, however, is only one part in a chain of events that must occur for a fire to start. Other events may include: failure of thermostat and limit switches in the dryer, lint inside the dryer, a missing or damaged lint screen, and a crushed hose behind the dryer. Allowing a dryer to run with a clogged vent will not only cost you more to run it but reduce its life span considerably. Many fire departments and insurance companies do require that dryer vents be inspected and cleaned regularly.

  • how often do vents need cleaning?

    Dryers are really designed to be positioned right on an exterior wall and vent directly out. In modern construction we see dryers placed, for convenience, smack in the middle of the house. Then you have a 30 foot vent to the exterior wall or a 15 foot vent to the roof. With a long dryer vent like that and multiple people in the family it MUST be done every year. Full size, brand new dryers blow better than smaller stack dryers or older dryers and therefore collect less lint in the vent system. Vents with a lot of turns and elbows blow worse and build up more lint. Most vents should be cleaned once a year as preventative maintenance. If you live alone and have a small vent then you can probably get away with every other year.

    Most multi-unit buildings can be cleaned for $10.00 to $30.00 depending on the level of lint and size of the complex

  • do we do dryer vent repairs?

    Typical vent repairs that we perform include: Replacing or repairing venting in attics or crawl spaces; removing small sections of drywall in laundry closets to repair or replace venting; and drilling holes in walls to run new venting. We cannot "finish" drywall. We cannot cut holes through flat roofs but we can replace or install a roof vent on a shingle roof. Parts, labor and trip charges make the average vent repair cost between $99 and $799 depending on the length and ease of access.

  • how do we sweep chimneys?

    We utilize a method referred to as Power Sweeping. As the name suggests, it's a lot more powerful and aggressive than the traditional method of chimney sweeping. The brush used for power sweeping looks very different than the traditional brush. The rods clip together as they go up the chimney and a drill with an adapter is used at each stage to spin the head. The head is made of tough plastic cables which when combined with the centrifugal force of the head, allows for the chimney to be cleaned with a lot more vigor than your standard chimney sweep. Power sweeping leaves the interior of the flue extremely clean.

  • are dirty chimneys a fire hazard?

    Regardless of whether you burn wood or have a gas appliance, your chimney both carries products of combustion and creates dangerous deposits which build up on the inside walls. Wood burning leaves creosote and ash on the inside walls of your chimney, which can be extremely flammable. As creosote builds up, so does the threat of a damaging fire which could escape the chimney and damage your home and potentially be hazardous to your family. Gas appliances on the other hand leave sulfur within metal chimney pipes, which can mix with condensation and create a sulfuric acid that both damages the pipe and works its way down into the appliance causing premature failure. Both fuel sources create carbon monoxide, which can escape a damaged flue and migrate into your home. Carbon Monoxide is a tasteless, colorless, odorless gas that kills almost 200 people every year in the U.S.

  • how often do chimneys need cleaning?

    The Chimney Safety Institute and the National Fire Protection Association both recommend annual cleanings for both chimneys and flues. Even if you don’t use your chimney regularly, there can be still many issues that aren't visible without the proper training and equipment.
