Cracks in the chimney can be very serious, depending on their location and size. Even small cracks can become serious over time if left unrepaired. Cracks allow heat and moisture to deteriorate your chimney and harmful carbon monoxide gas to seep into your home. Small cracks can often be caulked, while large cracked sections may require full replacement.

Yes, if your gas fireplace has a flue, you typically need to open it when using the fireplace. Although gas fireplaces don’t produce the type of smoke and soot that wood-burning ones do, they still release combustion gasses like carbon monoxide. Opening the flue ensures these gasses safely exit your home through the chimney. Not all gas fireplaces need a chimney, however. Always check the manufacturer’s instructions for your specific gas fireplace model, as some newer models may have different ventilation requirements.

Chimney caps are necessary both from a building safety standpoint in most municipalities and to keep your home protected from a variety of issues. Chimney caps are not only mandated by building code in most areas, but they also serve to keep squirrels, raccoons, and other pests out of your home, as well as snow and rain. Therefore, they help to avoid property damage, making them a worthwhile investment.

Well-seasoned hardwoods like oak, maple, hickory, and ash are the cleanest woods to burn in a fireplace. When properly dried, these woods have low moisture content, allowing them to burn hotter and produce less smoke, which minimizes creosote buildup. Ensure the wood is seasoned for at least six months for optimal burning.
