Before St Davids summer heats up, give your chimney a quick safety check. Clear debris, inspect for cracks, and test the damper—simple steps that prevent costly repairs and keep your home safe all season.
Step 1: Clear debris and inspect the exterior
Stand back and scan your chimney’s exterior for loose bricks, cracks, or leaning sections—especially after St Davids’ spring storms. Use binoculars if needed. Remove any leaves, twigs, or bird nests from the chimney crown or flue opening with a broom or brush. Never climb onto the roof yourself; use a sturdy ladder on level ground and have someone spot you. If you spot crumbling mortar or missing bricks, mark the spot with tape and call a pro.

Step 2: Test the damper and flue
Open and close your chimney damper fully to ensure it moves freely and seals tightly when closed. A stuck or broken damper wastes energy and risks carbon monoxide leaks. Shine a flashlight up the flue from the firebox to check for obstructions or heavy creosote buildup. If you see thick black or tarry deposits, schedule a cleaning before summer. See our guide on chimney cap and damper installation in St Davids
Step 3: Check the chimney cap and flashing
Inspect the chimney cap for rust, cracks, or missing mesh that could let pests or rain enter. Look at the flashing where the chimney meets the roof—rust, gaps, or loose seams mean water damage risk. If the flashing is damaged, don’t climb on the roof; call a licensed sweep to reseal it properly. Waterproofing and flashing maintenance are critical in St Davids’ humid summers
Step 4: Schedule a Level 1 inspection (or call a pro)
Even if your chimney looks fine, St Davids homeowners should schedule a Level 1 inspection every year. This includes a visual check of accessible areas for damage, blockages, or creosote. If your chimney hasn’t been inspected in over a year, or you’ve noticed soot on walls, a smoky smell, or difficulty opening the damper, it’s time for a pro.

Warning signs you should never ignore
Stop DIY work immediately if you see cracks wider than a credit card, white efflorescence (salt stains) on bricks, or a leaning chimney—these signal structural failure. Also call a pro if you smell gas near the fireplace, hear loud cracking during warm days, or notice water stains on walls or ceilings near the chimney. These signs often mean hidden damage or dangerous blockages. See our local warning signs guide for St Davids homeowners

Frequently Asked Questions
What’s the safest way to remove leaves from my St Davids chimney crown without climbing on the roof?
Use a soft-bristle outdoor broom or a telescoping chimney brush from the ground to gently sweep debris off the crown. Never use a pressure washer or climb onto the roof yourself—St Davids’ slate and tile roofs are slippery and fragile. If debris is packed tight, call a pro to avoid damaging the crown or flashing.
How can I tell if my St Davids chimney’s mortar joints are crumbling before summer humidity sets in?
Look for white, powdery stains (efflorescence) on bricks or gaps you can probe with a screwdriver. Crumbling mortar often appears as loose sand or hollow sounds when tapped lightly with a tool. Early repairs prevent water intrusion during St Davids’ humid summers—don’t wait until cracks widen.
After a long winter, what’s the first thing I should check on my St Davids chimney before using the fireplace again?
Test the damper’s operation and inspect the flue for obstructions or heavy creosote. If the damper sticks or the flue feels rough, schedule a cleaning before your first summer fire. See our St Davids chimney troubleshooting checklist for safe next steps.
