7 Critical Signs Your New London Chimney Needs a Post-Storm Inspection (And What to Do Next)

By Davids Brothers Chimney Team · Updated October 31, 2026

A post-storm chimney inspection in New London is essential after high winds or ice damage. Look for cracked bricks, displaced mortar, or debris in the flue. If you see any of these 7 signs, call a chimney sweep immediately to avoid costly repairs or fire hazards. Never ignore damage, especially in older homes near the Thames River where moisture and salt air accelerate wear.

1. What is a post-storm chimney inspection?

A post-storm chimney inspection is a thorough check of your chimney’s structure, flue, and connections after wind, ice, or falling debris could have caused damage. In New London, where winter storms bring heavy ice and summer hurricanes can topple branches onto rooftops, this inspection ensures your chimney is safe to use. Unlike a routine cleaning, it focuses on identifying hidden damage, like cracks in the masonry or shifts in the flue lining, that might not be visible from the ground. The Chimney Safety Institute of America (CSIA) recommends this inspection after any severe weather event, especially if you hear unusual noises or see smoke behavior changes. New London homes with older brick chimneys are particularly vulnerable, so don’t wait until your next scheduled sweep.

2. 7 signs your New London chimney was damaged in a storm

After a storm, inspect your chimney for these red flags. Start by looking at the exterior from a safe distance, never climb on the roof yourself. If you spot any of these issues, schedule a chimney sweep inspection immediately: 1. Cracked or missing bricks: Wind can dislodge mortar, and ice can freeze and expand, cracking masonry. Check for loose bricks or mortar joints wider than 3/16 of an inch. 2. Debris in the flue: Fallen branches, leaves, or even ice chunks can block the chimney. If you see smoke backing up into your home or hear rattling, there’s likely an obstruction. 3. Rust or corrosion: New London’s coastal humidity and salt air accelerate metal corrosion. Look for rust stains around the damper or smoke chamber. 4. Water stains or leaks: Dark streaks on the ceiling or walls near the fireplace indicate a leaky chimney. Water damage weakens masonry and can lead to mold. 5. Shifting or leaning chimney: If the chimney appears tilted or separated from the roofline, the foundation may have shifted during the storm. 6. Creosote buildup changes: Storms can dislodge creosote, creating a dangerous powdery residue. If you notice excessive soot or a strong chemical smell, the flue lining may be compromised. 7. Animal activity: Storms can create entry points for birds, squirrels, or raccoons. Listen for scratching or scurrying inside the chimney, this is a sign of nesting or damage. If you’re unsure, use a flashlight to peer up the chimney from the fireplace. But never attempt to remove debris yourself, call a professional chimney sweep in New London to avoid injury or further damage. Learn how to spot chimney problems before they become emergencies.

3. How to prepare for your chimney sweep inspection in New London

Before scheduling a post-storm chimney inspection, gather key details to help the chimney sweep assess your chimney quickly and accurately. Start by noting: - The type of storm: Was it high winds, ice, or a combination? This helps the technician identify potential damage patterns. - Any unusual noises or smells: Rattling, popping, or a strong chemical odor can indicate specific issues like loose bricks or creosote buildup. - Photos or videos: Take pictures of visible damage from multiple angles. If you’ve noticed water stains or soot, document those too. - Your chimney’s age and materials: Older brick chimneys or those with clay flue linings are more prone to storm damage. If your home is near the Thames River or in a flood zone, mention this, moisture and salt air weaken masonry over time. - Recent repairs: If you’ve had any work done, share details like the date and type of repair. This helps the chimney sweep understand your chimney’s history. Once you’ve gathered this information, contact a licensed chimney sweep in New London. At Davids Brothers Chimney, we offer free estimates and arrive with the right tools to diagnose issues without guesswork. See our service areas to confirm we cover your neighborhood. During the inspection, we’ll use a chimney camera to check for hidden damage, measure draft flow, and test for carbon monoxide leaks, steps that generic sweeps often skip. The National Fire Protection Association (NFPA) recommends this level of detail after storm damage, so don’t settle for a cursory glance.

4. What happens during a post-storm chimney inspection?

A professional post-storm chimney inspection in New London follows a structured process to ensure nothing is overlooked. Here’s what to expect when you schedule a visit: 1. Exterior inspection: The chimney sweep will examine the masonry, flashing, and crown for cracks, missing mortar, or water damage. They’ll check for signs of shifting or separation from the roofline. 2. Flue and liner inspection: Using a chimney camera, they’ll inspect the flue for debris, rust, or creosote buildup. This is critical, hidden damage in the flue can lead to chimney fires or carbon monoxide poisoning. 3. Draft and airflow test: They’ll measure how well your chimney draws smoke upward. Poor draft is a common issue after storms, often caused by blocked flues or damaged liners. 4. Smoke chamber check: The area where smoke collects before exiting the chimney is inspected for soot, rust, or structural weaknesses. 5. Carbon monoxide test: A handheld detector will check for leaks, which are especially dangerous in older homes with outdated chimneys. 6. Safety recommendations: Based on their findings, the chimney sweep will provide a detailed report and recommend repairs or maintenance. For example, if the flue lining is corroded, they may suggest relining or sealing cracks in the masonry. The inspection typically takes 60–90 minutes, depending on the chimney’s complexity. Unlike a routine sweep, this is a diagnostic process, think of it like a car inspection after a fender bender. Understand the difference between a sweep and an inspection to know what to expect from your visit.

5. How much does a post-storm chimney inspection cost in New London?

The cost of a post-storm chimney inspection in New London varies based on the chimney’s height, materials, and the extent of damage. Here’s a general breakdown of what to expect: - Basic inspection (Level 1): $120–$200. This includes peeking at the parts of the chimney and fireplace you can see, plus testing how well air flows through it. Ideal if you only suspect minor damage. - Camera inspection (Level 2): $180–$280. Adds a flue camera to check for hidden debris, creosote, or liner damage. Recommended after storms to rule out internal issues. - Full diagnostic (Level 3): $250–$400. Includes a thorough inspection of all chimney components, often required for older homes or after severe storms. May involve removing parts of the chimney for a closer look. - Emergency repairs: If the inspection reveals urgent issues like a blocked flue or cracked liner, additional costs apply. For example, relining a chimney can range from $1,200 to $3,500, depending on the materials and chimney height. At Davids Brothers Chimney, we provide transparent pricing upfront and never upsell unnecessary repairs. Many homeowners in New London worry about hidden fees, but we include all findings in a written report before any work begins. Review our pricing guide for more details. If you’re unsure whether your chimney needs an inspection, ask yourself: Did the storm bring high winds or ice? Did you hear unusual noises from the chimney? Is there smoke lingering in your home? If the answer is yes, schedule the inspection, it’s cheaper than repairing storm damage later.

6. When should you schedule a post-storm chimney inspection in New London?

Timing matters when it comes to post-storm chimney inspections. The sooner you act, the less damage can worsen, and the lower your repair costs will be. Here’s when to schedule: - Within 48 hours of the storm: If you notice obvious damage like fallen debris or visible cracks, call a chimney sweep immediately. Delays can lead to water leaks, which weaken masonry and encourage mold growth. - Before your next fire: Never use your fireplace or furnace until a chimney sweep confirms it’s safe. Storms can dislodge creosote or damage the flue, creating fire hazards. - Before winter sets in: If the storm occurred in late fall, schedule the inspection before the first freeze. Cold weather can exacerbate cracks and make repairs more difficult. - After ice storms: New London’s coastal climate means ice storms are common. If ice formed in your chimney, it can melt and refreeze, causing internal damage. A post-storm inspection ensures no hidden ice-related issues remain. Pro tip: If you’re unsure whether to wait, err on the side of caution. Many chimney sweeps in New London offer same-day or next-day appointments after storms. See our availability for emergency inspections. Remember, insurance may cover storm-related chimney damage if you act quickly, document the damage with photos and contact your provider before repairs begin.

7. What to do if your chimney inspection reveals damage

If your post-storm chimney inspection uncovers damage, the next steps depend on the severity. Here’s how to handle common findings: - Minor cracks or loose mortar: These can often be repaired with a repointing service, which costs $300–$800 in New London. The chimney sweep will recommend the best sealant for your masonry. - Blocked flue or creosote buildup: A deep cleaning may be needed, especially if the creosote is powdery or tar-like. This can range from $150 to $300, depending on the chimney’s height and obstruction level. - Rust or corroded liner: If the flue liner is compromised, it may need to be relined or replaced. This is a critical repair, never ignore it, as a damaged liner can’t protect your home from chimney fires. Costs vary widely ($1,200–$3,500) based on materials and chimney access. - Water leaks or foundation shifts: These require immediate attention. A chimney sweep can recommend a waterproofing treatment or structural repairs. In older New London homes near the Thames River, moisture is a persistent issue, so proactive sealing is key. - Animal nests or debris: If birds or squirrels have taken up residence, a sweep will remove the nest and seal entry points. This often involves installing a chimney cap, which costs $150–$400. After the inspection, you’ll receive a written report outlining the damage, recommended repairs, and estimated costs. At Davids Brothers Chimney, we’ll also provide a timeline for repairs and explain how to prioritize them. For example, fixing a blocked flue takes precedence over cosmetic masonry repairs.
