Bundled two services, saved the trip fee
Had the chimney and the dryer vent done on the same visit. Cheaper and half the disruption.

Reliable across three jobs
Used them for a sweep, a dryer vent, and a fireplace service. Same standard every time and the same technician twice, which I appreciated.

How often should a Thornlea, Markham home book chimney and fireplace service?

Once a year before the heating season. Thornlea, Markham's freeze-thaw cycles are hard on crowns, caps, and mortar joints, and an annual inspection catches water entry and creosote build-up while both are still cheap to fix.
