Question 1

How often should I have my chimney swept?

Accepted Answer

Most fireplaces and wood stoves used regularly should be swept and inspected once a year, ideally before the first fire of the heating season. If you notice a smoky smell, poor draft, or visible soot buildup, schedule a sweep sooner. 21st Century Chimney Sweep has served the Lawrence, Kansas area since 1978 and includes a professional inspection with every visit.

Question 2

What causes chimney bricks to crack or flake?

Accepted Answer

This is called spalling. Water soaks into brick or mortar, freezes, and expands, fracturing the surface — most often in the section above the roofline. It worsens each winter if untreated, but caught early it can usually be fixed with sealant or a proper cap instead of a full rebuild.

Question 3

Do I need a chimney cap?

Accepted Answer

Yes. An uncapped chimney is one of the most common entry points for rain, snow, and animals, leading to water damage, blockages, and nesting hazards. A properly fitted cap, or a custom full-coverage cap for chimneys with multiple flues, protects the chimney while still allowing smoke to vent safely.

Question 4

Why do masonry chimneys often leak at the top?

Accepted Answer

Most chimneys are originally built with a mortar wash — a thin, hand-formed layer of mortar with no reinforcement, overhang, or drip edge. This is why so many masonry chimneys eventually leak and spall near the top. A properly built crown using reinforced concrete with a drip edge is the best way to avoid this problem.
