Rockville homes and their chimneys
Half of Rockville's homes were built in 1979 or later, and only 2.3% date from 1939 or earlier. HomeGuide's list of common stainless steel liner jobs includes matching modern heating appliances that need a different liner and installing liners in prefabricated fireplaces, not only lining old brick chimneys.
Rockville winters and your chimney
Rockville averages 60 nights a year at or below freezing and a December to February average of 39.7°F (NOAA normals, Washington Reagan Airport). That matters for the outside of the chimney: HomeGuide says cracks in brick and mortar usually start small at the corners but can expand quickly if water seeps in and freezes. Brick repair runs $150 to $500 for minor cracks and $1,000 to $3,500 for replacing brick from the crown to the roofline, according to HomeGuide.
Chimney fires in Maryland

Local rules and resources in Rockville
The City of Rockville's building and trade permit page says commercial and residential properties must obtain permits before starting construction projects related to certain types of work, such as electrical, plumbing, mechanical or structural work. That page lists a Mechanical Permit among its trade permit applications, and it does not name chimneys, fireplaces or stoves. Rockville's Inspection Services Division Technical Bulletin 2017-1-ISD, effective 11-8-17, says that where an alteration, repair or addition that requires a permit occurs in a 1 or 2 family dwelling, the dwelling must be equipped with smoke alarms as a new dwelling. The bulletin lists exceptions for work involving exterior surfaces, such as roofing, siding, windows, doors, porches and decks, and for plumbing and mechanical work.
Rockville's Fire Safety page, which lists the city's Fire Marshal's Office (240-314-8240) as its contact, says the Maryland Smoke Alarm Law passed during the 2013 Maryland General Assembly requires replacing smoke alarms 10 years after the manufacturing date printed on the back of the alarm. The same page says that, effective Jan. 1, 2018, homes built before Jan. 1, 1989 must have at least one approved, AC-powered smoke alarm on every level, though sealed battery-operated alarms with long-life batteries and hush buttons may be used where wired alarms did not previously exist.
For outdoor fire pits, fire bowls and chimineas only, the Inspection Services Division's guidelines say no permit is required from the division or from the Montgomery County Department of Environmental Protection. Those outdoor devices must be at least 30 feet from any non-single family building or structure and should be at least 15 feet from any townhouse, duplex or detached home, and the guidelines say to burn only aged dried wood and not to use them on Code Orange or Code Red Air Quality days.
