How to Spot Trouble with Your Chimney Before Fireplace Season

As the days get shorter and the air gets cooler, many homeowners look forward to that first cozy fire of the season. But before you strike a match, it’s important to make sure your chimney is in good working order. A damaged or blocked chimney doesn’t just reduce efficiency - it can create serious safety hazards, including chimney fires and carbon monoxide buildup. The good news? A little preventative maintenance now can save you from expensive repairs and dangerous situations later.

Here’s what to look for when checking your chimney this fall.

Cracks and Gaps in the Masonry

Start with a visual inspection. If you see crumbling mortar, missing bricks, or hairline cracks, that’s a sign your chimney is weakening. Water can seep into these gaps, freeze in the winter, and make the damage worse. Over time, this can compromise the entire structure. Small cracks can often be sealed, but larger problems usually require professional repair.

A Damaged Chimney Cap or Crown

Your chimney cap is the unsung hero of the fireplace system. It keeps out rain, snow, animals, and debris. Without it, your chimney can quickly become clogged or water-damaged. Similarly, the chimney crown - the cement slab at the very top - acts as a shield. If you notice rust on the cap or chips in the crown, it’s time to repair or replace before moisture finds its way inside.

Creosote Buildup

Even if the outside looks fine, the inside of your chimney can be another story. Burning wood produces a tar-like substance called creosote, which clings to the interior walls. Creosote is highly flammable, and too much of it can spark a chimney fire. If you notice a strong, smoky odor, or if you can see black, shiny buildup inside, schedule a professional cleaning before you use the fireplace again.

Signs of Water Damage

Look around the base of your chimney and inside your attic for water stains or dampness. Discoloration on ceilings and walls near the chimney can be a red flag. Water entering through cracks or missing flashing (the metal seal where the chimney meets the roof) can cause mold, rot, and costly structural issues.

While You’re Up There - Check Your Roof

Inspecting your chimney is also a great opportunity to take a quick look at your roof. Loose, curling, or missing shingles can lead to leaks that damage not only your chimney but your entire home. Shingle problems are easiest to fix when they’re caught early, so don’t wait until you see water spots inside your house to take action.

When to Call a Pro

Some issues, like trimming back tree branches or replacing a simple cap, may be safe for homeowners to tackle. But climbing on a roof always comes with risks, and chimney repairs often require professional tools and expertise. If you’re unsure about the condition of your chimney or roof, schedule an inspection with a qualified contractor. It’s a small investment that can prevent big problems down the line.

A healthy chimney doesn’t just make your fireplace more efficient; it keeps your family safe, too. Take a little time this season to inspect for cracks, damaged caps, creosote buildup, and signs of water leaks. And while you’re up there, give your roof a once-over, too. A careful check now means peace of mind when you’re enjoying those winter nights by the fire.

Keep Your Home Cooler with These Summer A/C Tips

As temperatures and humidity rise, many homeowners turn up the air conditioning to stay comfortable. However, overworking your A/C system without proper maintenance can lead to reduced efficiency, an increased likelihood of mold, and potential water damage. Here are several ways to stay cool while keeping your house’s health in check.

1. Replace or clean your air filter regularly.

A clogged air filter can reduce your A/C’s efficiency by up to 50%. Check your filter monthly and replace or clean it as needed. A clean filter improves airflow, helps the unit cool more effectively, and reduces the amount of dust, pollen, and mold in the air. When selecting a filter, consider its MERV (Minimum Efficiency Reporting Value) rating. Residential units typically use filters with a MERV rating between 1 and 12. Higher ratings trap smaller particles and can improve indoor air quality.

2. Seal gaps around window units.

Window air conditioners can allow warm, humid air into the home if not properly installed. Use foam insulation or foil tape to seal gaps around the unit. This reduces energy loss and keeps your space cooler. Materials are inexpensive and available at most hardware and home improvement stores.

3. Use a programmable timer or smart plug.

Air conditioners use a significant amount of energy. Avoid running your unit at full power when you’re not home. A programmable timer or smart plug can adjust the temperature while you’re away and return it to a comfortable level before you arrive. This helps reduce wear on the system and can lower energy bills.

4. Check attic insulation and ventilation.

Poor attic insulation can make it harder to keep your home cool, especially on hot days. If your ceiling feels warm to the touch, it may indicate that there is insufficient insulation. Improving insulation and ventilation helps maintain indoor temperatures and reduces the strain on your A/C system. This also benefits your home during the winter months.

5. Inspect your system for leaks.

Water leaks from central A/C units often result from a cracked drain pan, clogged filter, or a blocked condensate line. These issues can lead to water damage in ceilings or walls. If you notice any signs of leaking, turn off the system and inspect these areas promptly. Addressing small issues early can prevent costly repairs later.

Staying cool doesn’t have to come at the cost of high energy bills or home damage. With a few simple checks and low-cost upgrades, you can improve your air conditioner’s performance and keep your home comfortable all summer long. Regular maintenance now can also extend the life of your system and help prevent unexpected breakdowns when the heat is at its worst.

A Roof and Gutter Inspection Checklist for Spring

After a long New England winter, your roof and gutters deserve a little TLC. Spring is the perfect time to inspect for any damage left behind by winter and prep your home for the warmer season ahead. Here’s a simple 10-step checklist to help you spring into action because a quick, proactive check now can save you serious money and headaches down the road. 

1. Safety First. Start smart. Use a sturdy ladder on flat ground, wear shoes with good traction, and don’t go it alone. If your roof is steep or high, consider a safety harness or call in a pro.

2. Ground-Level Walkaround. Before climbing anything, take a walk around your home. Look up and scan for missing or damaged shingles, sagging rooflines, or any debris buildup from winter storms. A pair of binoculars is a handy tool here.

3. Inspect the Roof Surface. If it’s safe, climb up for a closer look. Winter’s freeze-thaw cycles can loosen shingles, damage flashing, and open up trouble spots. Focus on high-risk areas like valleys, chimneys, and skylights.

4. Flashing & Seal Check. Snow and ice can crack flashing and wear down seals around vents and roof joints. Look for gaps or rust, and re-seal any areas that no longer look watertight.

5. Clean Out the Gutters. Winter storms can clog your gutters with leaves, pine needles, and shingle grit. Clear out all debris and make sure water flows freely through the downspouts—otherwise, you’re risking water damage and foundation issues.

6. Confirm Gutter Slope. Gutters should slope slightly toward the downspouts. If water pools or overflows, grab a level and check. Adjust the hangers as needed to restore proper drainage.

7. Check Fascia & Soffits. Cold, wet weather is hard on wood. Look for signs of rot, peeling paint, or pest activity on the fascia boards and soffits—these areas often show the first signs of hidden water damage.

8. Peek Into the Attic. Head inside and inspect the underside of your roof. Water stains, mold, or musty smells could mean you’ve got a leak. Also check that your attic vents are clear to allow air to circulate and moisture to escape.

9. Take Photos. Snap pictures of anything that looks questionable. These will come in handy if you need to call a contractor—or if an insurance claim is necessary.

10. Schedule a Pro Inspection. Even if everything looks good, a professional inspection once a year is a smart move. Pros know where to look for hidden issues and can help extend the life of your roof with early fixes.

Spring is the season for fresh starts and smart maintenance. Your roof worked hard all winter. Give it the attention it deserves this spring so it can keep doing its job all year long. A little maintenance now means fewer surprises later.
