Chimney Inspection Before Selling a House

Is a chimney inspection required to sell?

In the areas we serve, we are not aware of a statewide rule in New York, New Jersey or Pennsylvania that requires a chimney inspection before a home is sold. Some municipalities run their own resale inspections under local ordinances, and those can touch on heating equipment or fire safety, so check with your town or city before listing.

New Jersey has a specific sale requirement that people often confuse with a chimney rule. Before a one- or two-family or attached single-family home is sold, leased or otherwise changes occupancy, the owner must obtain a certificate of smoke alarm, carbon monoxide alarm and portable fire extinguisher compliance from the enforcing agency. State materials say it is obtained through the municipality and is valid for six months from issue. It covers alarms and an extinguisher, not the chimney.

Why sellers inspect anyway

Buyers' home inspectors look at chimneys, but usually only what they can see from the roof edge, the firebox and the attic. When they spot something that might be a problem, such as cracked brick, a missing cap, staining or a damper that will not close, the report often says to have the chimney evaluated by a specialist. That sentence arrives in the middle of your contract period, with a deadline and a buyer who now imagines the worst.

Inspecting first lets you know what is there while you still control the timing. You can repair, get a written estimate, or price the issue in, on your schedule rather than the buyer's.

A pre-listing report also helps price the house honestly. If a chimney needs a rebuild above the roof, you can decide whether to do it or reflect it in the asking price, instead of conceding a larger credit under deadline.

What buyers' inspectors commonly flag

In older housing stock, these are the chimney items that turn up most in buyers' reports.

• No cap, or a rusted cap, on one or more flues
• A cracked crown or mortar wash at the top
• Open mortar joints and spalled brick above the roof
• Old tar around the flashing, or stains beside the chimney inside
• A water heater alone in a large flue after a boiler upgrade
• Creosote, nests or debris in a fireplace flue
• No visible liner, or cracked tile seen from the firebox

Fix, disclose or credit

When the inspection finds something, sellers generally have three paths. The right one depends on the problem, the market and your timeline, so decide it with your agent.

• Repair before listing: suits safety items and visible defects buyers will spot. Keep the invoices and report to show them
• Disclose and price in: suits larger projects, like a rebuild, backed by a written estimate. Buyers may still ask for more
• Offer a credit at closing: suits issues found late, under time pressure. Credits tend to be negotiated up from estimates

Safety items come first

Some findings are not negotiation points, they are hazards. A cracked or missing liner serving a boiler or water heater, a disconnected or rusted-through connector pipe, a blocked flue, or loose brick at the top of a chimney that overhangs a sidewalk should be dealt with whether or not the house sells. A buyer's lender or insurer may also require them fixed before closing.

Carbon monoxide is the reason venting problems rank highest. Exhaust leaking from a failed flue is dangerous, and working CO alarms are required in New Jersey homes with fuel-fired appliances or attached garages.

Fireplaces that are not used

Many sellers have not lit their fireplace in years and assume it does not matter. Buyers see it differently: a fireplace is a feature in the listing, and a buyer expects to use it. If yours has been closed off, an inspection tells you whether it is usable as is, needs a sweep and minor repair, or needs a liner before it can be used. Any of those answers is easier to handle before listing than after an offer.

If you do not want to make an unused fireplace usable, say so plainly in the listing and disclosure, and make sure the flue is capped and sealed so it does not leak or invite animals. A fireplace described as decorative only, with that status documented, is rarely a sticking point.

Disclosure

Each state has its own seller disclosure rules, and some ask about fireplaces, chimneys, heating systems or past water and fire damage. What you know, you may need to disclose, and an inspection report is something you know. That is a reason to inspect early and resolve what you can. The details are a legal question for your attorney or agent; this guide is not legal advice.

What a pre-sale inspection covers

A chimney inspection for a sale looks at everything a buyer's inspector might question, and more. Inside: the firebox, damper, smoke chamber and the flue as far as it can be seen, the connectors from the boiler and water heater, and the cleanout. Outside: crown, cap, the brick and mortar above the roof, and the flashing. Each flue is identified and described.

The written report is the useful part for a sale. A clear description of what was found, separated into safety items and maintenance, gives buyers and their inspectors something concrete to read in place of a vague warning.

Timing and paperwork

The ideal time is before listing photos are taken, so any repairs, especially masonry or crown work that depends on weather, can be finished and the report is ready to hand over. If you are already under contract, book as soon as the buyer's inspection report arrives, so you have a specialist's findings and a written estimate before the response deadline. Our crews can schedule sale inspections quickly, and repair estimates come free and in writing.

Buyers and their insurers ask the same questions sellers' agents dread. Pull together any past sweep and inspection reports, repair invoices, liner documentation, permits for boiler or stove installations, and the manual for any wood stove or insert. In New Jersey, add the alarm certificate once the town issues it. A short folder of documents makes the chimney a non-issue at the closing table. Keep copies for yourself as well.
