Expert Washington Crossing Chimney Sweeping

COMMON QUESTIONS

chimney sweeping FAQS

Do I need to move furniture or cover the floor before the sweep arrives?

Please move furniture, rugs, and decorations back from the fireplace so there is room to work and to lay down protection. You do not need to cover the whole room. Professional sweeps typically bring drop cloths and use a vacuum system to help keep soot out of the living space. If a piece is too heavy to move, say so when you schedule so the technician can plan around it. Clearing the immediate hearth area is the most helpful step you can take in advance.

Does a gas fireplace still need an annual inspection even if it stays clean?

A tidy gas fireplace can still have a blocked or damaged vent, which is why an annual inspection matters even when little soot is visible. CSIA-certified technicians check the venting and the appliance, then clean as needed. Washington Crossing homeowners should keep gas units on the same yearly inspection calendar as wood systems, even if sweeping is less often required. If you also have a wood-burning fireplace, schedule both during the same appointment when you can.

Can animal nests or debris be cleared during a regular chimney sweep?

Often, yes. Leaves, twigs, and many nests can be removed as part of a professional sweeping once the technician can reach them safely. If a blockage is packed, or if an animal is present, extra care or a follow-up may be needed. After the flue is cleared, the inspection continues so any damage or missing cap is noted. A cap, where appropriate, helps make a repeat nest less likely. Do not try to burn out a nest or reach into the flue yourself.

Can I wait to book until I notice a problem, or should I schedule ahead?

Schedule ahead. NFPA 211 recommends an inspection at least once a year, not after a problem appears. Creosote, blockages, and weather damage can develop without obvious signs in the room. Waiting until you smell smoke or see a draft issue means the system is already overdue for a look. A planned visit also makes it easier to get on the calendar before the busy fall season. If you already notice a problem, book promptly and mention the symptoms when you call or fill out the form.

What are common chimney problems found during a sweep and inspection? 

Cracked or spalled flue tiles from heat cycling or chimney fires Deteriorated mortar joints in the firebox or exterior masonry A missing, damaged, or improperly sized chimney cap Crown cracking or deterioration allowing water penetration Blocked flues from debris, nesting animals, or collapsed liner sections Many of these issues develop gradually and are not visible from inside the home, underscoring the value of professional annual inspection.

How do I know if I’ve had a chimney fire?

A loud cracking, rumbling, or roaring sound from the chimney Dense smoke or unusual odors coming from the fireplace Visible flames or sparks from the chimney cap Puffy, honey-combed, or blistered creosote on flue walls (observed during inspection) Warped or damaged damper, firebox walls, or chimney cap If you suspect a chimney fire has occurred, stop using the fireplace immediately and schedule a Level 2 inspection before burning again.
