Spring Maintenance (March – May): Post-Season Cleanup
Spring is your chance to address the wear and tear from a full heating season: Our learn about chimney caps covers this in depth. Learn more about chimney services in Oregon.
Schedule Your Annual Chimney Cleaning
Spring is the ideal time for your annual chimney sweep. Creosote and soot from winter burning should be removed before the off-season because moisture from spring and summer humidity can mix with creosote deposits, creating acidic compounds that accelerate flue deterioration. Scheduling in spring also means better availability and potentially lower prices before the fall rush. For more details, check out our chimney services in Washington. Our guide on chimney services in Virginia covers this topic in depth.
Get a Level 1 Chimney Inspection
Combine your cleaning with a professional inspection. Your chimney technician will check for cracks in the flue liner, deterioration of mortar joints, chimney cap condition, and any damage from winter weather. Catching problems in spring gives you months to plan and budget repairs before you need the fireplace again. Read our chimney services in California to learn more. Check out our resource on chimney services in Ohio for more information.
Clean the Firebox
Remove all remaining ash from the firebox — leave about 1 inch of ash for insulation if you have a wood-burning fireplace, but clean out the rest. Check the firebrick for cracks or damage. Damaged firebrick should be repaired or replaced before the next burning season. For more details, check out our summer chimney maintenance tips. Learn more about our Pennsylvania team.
Check the Damper
Open and close the damper several times to ensure smooth operation. Remove any debris or soot that may be preventing a proper seal. A damper that does not close tightly wastes conditioned air all summer long — essentially leaving a hole in your roof.
Inspect the Exterior
Walk around your home and examine the chimney exterior. Look for cracked mortar, leaning, missing bricks, and deteriorated chimney cap. Spring freeze-thaw cycles in Northern New Jersey and New York are especially hard on masonry.
Summer Maintenance (June – August): Protect and Repair
Summer is the best time for chimney repairs since you will not need the fireplace for months:
Address Any Issues Found During Spring Inspection
If your spring inspection revealed problems — cracked crown, deteriorated mortar, damaged flue liner — summer is the time to fix them. Masonry work requires dry, warm weather for proper curing. Do not wait until fall when demand increases and weather becomes unpredictable.
Waterproof the Chimney
Apply a breathable waterproofing sealant to the chimney exterior. This prevents water absorption while allowing moisture vapor to escape from inside the masonry. Water is the number one enemy of masonry chimneys — it causes freeze-thaw damage, efflorescence (white staining), and accelerated deterioration. Professional waterproofing costs $150 to $400 and can extend the life of your chimney by decades.
Check and Replace the Chimney Cap
A quality chimney cap prevents rain, animals, leaves, and debris from entering your flue. If your cap is damaged, rusted, or missing, replace it immediately. Stainless steel caps with mesh screening are the best investment — they resist corrosion and keep animals out. Caps cost $100 to $300 installed. Homeowners in Woodland Hills, CA (91364) and other areas with nearby trees should ensure the mesh is clean and unobstructed.
Close the Damper
Keep the damper closed during summer to prevent cooled air from escaping up the chimney and to keep humidity, insects, and animals out of your home. If you have a gas fireplace with a standing pilot, consult your manual — some require the damper to remain partially open. creosote buildup prevention
Fall Maintenance (September – November): Prepare for Burning Season
Fall is all about preparation. Before lighting that first fire of the season: spring chimney maintenance checklist
Pre-Season Inspection
If you did not get your annual inspection in spring, schedule it now — before the rush. D&D Chimney Cleaning sees booking increase 300 percent from October through December. Call (888) 217-2845 early to secure your preferred date.
Stock and Season Firewood
Purchase firewood early in fall and store it properly. Wood should be seasoned for at least 6 months with moisture content below 20 percent. Stack it off the ground, covered on top but open on the sides for air circulation. Keep it at least 20 feet from your home to avoid attracting pests.
Test Your Smoke and Carbon Monoxide Detectors
Before the first fire of the season, test every smoke detector and carbon monoxide detector in your home. Replace batteries and replace any units older than 10 years (smoke) or 7 years (CO). Install CO detectors on every level of your home, especially near bedrooms.
Check Your Fire Extinguisher
Keep a multipurpose ABC fire extinguisher within easy reach of your fireplace. Check the pressure gauge — if the needle is not in the green zone, replace it. Every household member old enough should know where the extinguisher is and how to use it. view inspection costs
Inspect the Fireplace Screen and Tools
Make sure your fireplace screen fits properly and has no holes or damage. A quality screen prevents sparks from reaching carpeting, furniture, and flooring. Check that your fireplace tools — poker, shovel, brush, and tongs — are in good condition.
Winter Maintenance (December – February): Safe Burning Practices
During active use, follow these practices for safe, efficient burning: fall chimney prep essentials
Burn Properly
- Open the damper fully before lighting a fire
- Use a fire grate to keep logs elevated for better air circulation
- Start with kindling and small pieces before adding larger logs
- Never burn more than the firebox can safely hold
- Allow fires to burn brightly rather than smoldering — hot fires produce less creosote
Manage Ash Properly
Remove excess ash when it builds up to 1 inch below the grate. Place ash in a metal container with a tight lid and store it outdoors on a non-combustible surface for at least 72 hours before disposal. Ashes can retain enough heat to start a fire for days after they appear cold.
Never Burn These Items
- Treated or painted wood (releases toxic chemicals)
- Wrapping paper (burns explosively and can send flaming debris up the chimney)
- Cardboard boxes (can float up the chimney while still burning)
- Plastic or trash (toxic fumes and creosote acceleration)
- Green or wet wood (maximum creosote production)
Monitor for Warning Signs
Throughout winter, watch for signs of chimney problems: smoke entering the room, unusual odors, difficulty starting fires, black staining on the chimney exterior, and white staining (efflorescence) on masonry. Address any concerns promptly by calling D&D Chimney Cleaning at (888) 217-2845.
Year-Round: Gas Fireplace Maintenance
Gas fireplaces require less maintenance than wood-burning units but still need regular attention:
- Annual professional inspection: Gas fireplaces should be inspected yearly to check the burner, pilot assembly, thermocouple, gas connections, and venting system.
- Clean the glass monthly during use: Use a gas fireplace glass cleaner (not standard glass cleaner) to remove white film and residue.
- Vacuum the burner and logs: Dust and pet hair accumulate on ceramic logs and burner ports, affecting flame appearance and potentially creating odors.
- Check the battery in the igniter: Remote control and electronic igniters use batteries that should be replaced annually.

Frequently Asked Questions
When is the best time to get a chimney cleaned?
The best time for chimney cleaning is in the spring, right after the burning season ends. This removes corrosive creosote before it sits all summer causing damage, and you avoid the fall rush when chimney companies are busiest. If you miss spring, early fall before you light the first fire is the next best option. D&D Chimney Cleaning offers year-round service — call (888) 217-2845 to schedule.

How do I maintain my fireplace between professional cleanings?
Between professional cleanings, maintain your fireplace by removing excess ash regularly, burning only seasoned hardwood, keeping the damper fully open during fires, checking smoke and CO detectors monthly, and visually inspecting the firebox for cracks or damage. Use creosote-reducing products as a supplement but not a replacement for professional cleaning. fireplace safety tips every homeowner should know
Should I close the damper in summer?
Yes, closing the damper during summer prevents conditioned air from escaping up the chimney, keeps humidity and insects out, and reduces energy waste. An open damper in summer is essentially a hole in your roof that allows cooled air to escape. The one exception is if you have a gas fireplace with a standing pilot light — check your owner manual for specific damper recommendations.
How do I know if my chimney needs repair?
Signs that your chimney needs repair include white staining on exterior bricks called efflorescence indicating water penetration, crumbling or missing mortar between bricks, a leaning chimney, rust on the damper or firebox, water stains on the ceiling or walls near the chimney, and pieces of flue tile in the firebox which indicates liner deterioration. Any of these signs warrant a professional inspection.
Can I use my fireplace if the chimney cap is missing?
While you technically can use a fireplace without a chimney cap, it is not recommended. A missing cap allows rain, snow, animals, and debris to enter the flue, which can cause blockages, moisture damage, and fire hazards. Animals frequently nest in uncapped chimneys, creating dangerous obstructions. Replace a missing chimney cap before using your fireplace — caps cost $100 to $300 installed and prevent thousands in potential damage.
