When done correctly by a professional, chimney repointing can last for several decades—often 30 years or more. This maintenance is crucial for keeping the chimney structure sound, improving its waterproofing, and preventing more significant and costly repairs, such as a partial or complete rebuild. It is recommended to schedule an annual inspection to catch any potential issues early. If you notice the chimney's brickwork looks worn out or crumbly, you should hire a professional to inspect it.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

They are capable of generating sufficient heat to keep homes comfortable during winter months. However, in regions with extremely low temperatures, you may need supplemental heating to ensure consistent warmth, especially during prolonged cold spells.
