If your Lacey chimney is leaking, stop using the fireplace immediately, cover the top with a tarp, and call an emergency chimney sweep service. Leaks in older brick chimneys often start at the crown, flashing, or joints, water damage can weaken masonry and create fire risks. Never ignore it; Lacey’s rainy winters make this especially critical for homes near the Chehalis River basin.
A chimney leak is water entering through cracks, gaps, or damaged masonry in your chimney structure. In Lacey, leaks often worsen during winter rains or after summer heat cycles, which can cause mortar to crumble in older brickwork.
A chimney leak isn’t just about water dripping inside, it’s about structural compromise. In Lacey, where homes built before the 1980s often feature solid masonry chimneys without modern waterproofing, leaks can seep into the flue liner, brick joints, or even the fireplace hearth. This moisture accelerates creosote buildup, weakens mortar, and can lead to dangerous chimney fires. The first sign is usually water stains on your ceiling or walls near the fireplace, but in older homes, you might also notice crumbling brick or rust stains on the damper. If you see any of these, your chimney needs immediate attention, especially before Lacey’s next heavy rain season.
The most common leak points in Lacey chimneys are: - Crown cracks: The concrete or brick cap at the top often develops hairline fractures from freeze-thaw cycles. - Flashing failures: The metal flashing around the chimney base or roof intersection can corrode or separate from the roof. - Mortar joint erosion: Older mortar in Lacey’s humid climate can degrade, leaving gaps for water to penetrate. - Missing or damaged chimney cap: Without a cap, rainwater pours directly into the flue.
If you suspect a leak, don’t wait for a routine inspection. Lacey’s climate, with its wet winters and dry summers, exacerbates masonry damage. Contact us for emergency service in Lacey if you see active leaks or water damage inside your home.
Stop using your fireplace immediately. Leaks can introduce water into the flue, which mixes with creosote to create a flammable sludge. This increases the risk of a chimney fire, especially in older homes with thick creosote deposits.
The first rule when you discover a leak is to stop using the fireplace or wood stove right away. Water entering the flue doesn’t just cause stains, it reacts with creosote (the tar-like byproduct of burning wood) to form a highly combustible paste. The National Fire Protection Association NFPA reports that creosote-related chimney fires account for thousands of incidents annually, and a leaky chimney is a primary contributor. In Lacey, where many homes still rely on wood-burning fireplaces, this risk is higher during fall and winter when usage peaks.
While you’re waiting for a chimney sweep, cover the top of the chimney with a waterproof tarp secured with bricks or weights. This won’t fix the leak, but it will prevent additional water from entering. Avoid DIY repairs like caulking or patching the crown yourself, these temporary fixes can trap moisture and worsen the problem. Instead, call a licensed Lacey chimney sweep who specializes in masonry repairs. They’ll assess whether the issue requires repointing mortar, recapping the chimney, or even replacing damaged bricks.
If the leak is severe, such as water dripping into your living space, turn off any ceiling fans or vents near the fireplace to prevent spreading moisture. Humidity from leaks can also encourage mold growth, which is a common issue in Lacey’s damp climate. For older homes, mold behind brickwork can go unnoticed until it’s deeply embedded, making professional inspection even more critical. Read up on our service list page.
Inspect the exterior of your chimney for visible damage. Look for cracks in the crown, rusted flashing, or crumbling mortar joints. In Lacey’s older neighborhoods like the historic downtown area, many chimneys lack modern waterproofing systems.
Before calling for emergency service, do a quick visual check of your chimney’s exterior. Start at the crown (the topmost layer). If it’s made of concrete, look for spiderweb cracks or chunks breaking away. Brick crowns should be solid with no missing pieces. Next, examine the flashing, the metal strip where the chimney meets the roof. Rust, separation from the roof, or gaps larger than a quarter-inch are red flags. Finally, run your hand along the mortar joints between bricks. If the mortar feels soft, crumbly, or has pulled away from the bricks, water is likely seeping in.
Lacey’s older homes, particularly those near the Chehalis River or in flood-prone areas like the southern end of town, often have chimneys built with sand-lime mortar, which is more porous than modern mortars. This type of mortar absorbs moisture like a sponge, leading to faster deterioration. If you’re unsure about the materials used in your chimney, a professional inspection will reveal whether the structure needs repointing (replacing damaged mortar) or a full chimney waterproofing system.
Pay special attention to the base of the chimney, where it meets the roof. If the flashing has pulled away, rainwater can run down the chimney’s exterior and pool at the base, causing brick erosion. In some cases, the damage might extend to the chimney chase (the exterior wall surrounding the chimney). If you notice sagging or bowing in the chase, this indicates water damage to the framing inside your home’s walls, a serious issue that requires immediate repair by a masonry specialist.
For a more detailed assessment, schedule a Level 2 chimney inspection the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) if your home is older than 20 years. This type of inspection includes removing obstructions and checking the flue liner for water damage or corrosion, which isn’t visible from the outside. There is more in contact the office page.
Check inside your home for water stains, rust, or mold. Leaks often leave traces on ceilings, walls, or the fireplace hearth. Lacey’s humid summers can hide these signs until they become severe.
Water from a leaking chimney doesn’t always stay outside, it often finds its way into your home. Start by looking directly above the fireplace for water stains on the ceiling or drywall. These stains might appear as dark rings or streaks, especially after rain. If your ceiling is painted, the stain might look like a watercolor bleed. In older homes with plaster walls, you might see peeling paint or bubbling where moisture has seeped through.
Next, inspect the fireplace hearth. Rust stains on the damper or metal components indicate water is entering the flue. If the damper is stuck or rusted shut, this is a fire hazard and requires professional repair. Check the firebox walls for damp spots or a musty smell, this is a sign of hidden mold growth. Mold behind brickwork is particularly dangerous in Lacey’s climate, as the combination of wood smoke residue and moisture creates an ideal environment for toxic spores.
If you have a cathedral ceiling or vaulted space (common in newer Lacey homes built on older foundations), leaks can travel farther before becoming visible. In these cases, look for stains along the joists or rafters near the chimney. Water damage here can weaken structural supports over time, leading to costly repairs. For homes with basements or crawl spaces, check the ceiling below the fireplace for sagging or water intrusion, this suggests the leak has compromised the chimney’s foundation.
If you find any of these signs, document them with photos before calling a chimney sweep. This helps the technician assess the extent of the damage and provides evidence for insurance claims if needed. Lacey homeowners should also check their attic insulation near the chimney, wet insulation loses its effectiveness and can promote mold growth. For a deeper inspection, a thermal imaging scan can reveal hidden moisture behind walls, which is especially useful for older homes with solid masonry.
Call an emergency chimney sweep service in Lacey. DIY fixes like caulking or patching won’t address the root cause of leaks in older masonry chimneys. Licensed technicians can assess and repair cracks, repoint mortar, or install waterproofing systems.
Once you’ve confirmed a leak, the next step is to contact a licensed Lacey chimney sweep who specializes in masonry repairs. Not all chimney services offer emergency leak repairs, so look for a company with experience in older homes and brickwork, like those in Lacey’s historic neighborhoods or near the Chehalis Valley. A true emergency service will respond within 24–48 hours to assess and mitigate the damage before it worsens.
When you call, be prepared to describe: - The location of water stains inside your home. - Any visible damage on the chimney’s exterior (cracks, rust, missing bricks). - Whether you’ve noticed smoke or soot leaks when the fireplace is in use (a sign of a compromised flue).
A professional will determine if the leak requires: - Repointing: Replacing damaged mortar between bricks to restore the chimney’s waterproof barrier. - Chimney cap replacement: Installing a new, durable cap to prevent water entry. - Flashing repair or replacement: Sealing the gap between the chimney and roof with new, corrosion-resistant flashing. - Waterproofing system installation: Applying a flexible membrane to the chimney’s exterior to redirect water away from the masonry.
In Lacey, where many homes have unlined masonry chimneys, leaks can also damage the flue liner over time. If the liner is corroded or cracked, it may need replacement with a stainless steel liner, which is more resistant to water and creosote. For older homes, this is often part of a full chimney restoration to meet modern safety standards.
Avoid companies that offer cheap, temporary fixes like silicone caulk or roofing cement. These solutions fail quickly in Lacey’s climate and can trap moisture, leading to worse damage. Instead, choose a chimney sweep with CSIA certification and experience in masonry repairs. They’ll provide a detailed estimate and explain the long-term solution for your specific chimney type. For a free consultation, visit our Lacey service page to discuss your options.
Prevent future leaks with routine maintenance. Lacey’s climate demands annual chimney inspections and sweeps, especially for older homes. Schedule a Level 1 inspection before winter to catch leaks early.
Once your chimney is repaired, take steps to prevent future leaks. Lacey’s wet winters and dry summers create ideal conditions for masonry deterioration, so proactive maintenance is key. Start with an annual chimney inspection before the heating season begins. The Chimney Safety Institute of America CSIA recommends this to ensure your chimney is safe and leak-free. For older homes, a Level 2 inspection (which includes checking the flue liner) is even more critical, as it reveals hidden damage from past leaks.
In addition to inspections, schedule a chimney sweep at least once a year, or more often if you burn wood frequently. Creosote buildup increases the risk of chimney fires, and a clean flue reduces the chance of water damage from condensed moisture. If your chimney has a single-wall masonry flue (common in older Lacey homes), it’s more vulnerable to leaks, so extra care is needed.
Consider these leak-prevention tips for Lacey homeowners: - Install a chimney cap if you don’t have one. A well-sealed cap blocks rain and debris while allowing smoke to escape. - Apply a chimney waterproofing system if your masonry is porous. Products like ChimneySaver or Flex Seal create a barrier against moisture without altering the chimney’s appearance. - Check the flashing annually. Replace rusted or separated flashing before it allows water to seep into the chimney. - Keep gutters and downspouts clear of debris. In Lacey, clogged gutters can cause water to overflow and pool near the chimney base, accelerating erosion. - Use seasoned hardwood for burning. Wet or green wood produces more creosote, which can clog the flue and trap moisture.
For homes in Lacey’s older neighborhoods, such as those near the Lacey Center or along 5th Avenue, consider upgrading to a double-wall stainless steel liner. While this requires more extensive work, it adds a secondary layer of protection against water and creosote. If you’re unsure about the best solution for your chimney, consult a masonry specialist during your next inspection. They can recommend upgrades tailored to Lacey’s climate and your home’s age.
Finally, keep an emergency chimney repair kit on hand for minor issues, such as a chimney cap repair patch or high-temperature sealant for small cracks. However, these are only temporary fixes, always follow up with professional repairs to avoid recurring leaks. For more tips on maintaining your Lacey chimney, visit our maintenance guide.

Frequently Asked Questions
My chimney is leaking, but I don’t see any water inside my home. Should I still be worried?
Yes. Even if you don’t see visible leaks indoors, water can still damage your chimney’s mortar joints, flue liner, or crown, especially in Lacey’s humid climate. Hidden moisture accelerates creosote buildup, which increases fire risks. Schedule an inspection to check for exterior cracks or rusted flashing, which are common in older masonry chimneys. Ignoring these can lead to costly repairs down the line.
Why does your brick chimney let in water after a Lacey downpour? Should you be worried?
No, it’s not normal. Lacey’s frequent winter rains should be kept out by a properly sealed chimney. If leaks worsen after rain, your crown, flashing, or mortar joints are likely failing. Older brick chimneys, common in neighborhoods like Old Town Lacey, often lack modern waterproofing. A repointing or waterproofing system can restore the barrier. Never wait, prolonged leaks weaken masonry and create fire hazards.
Can I fix a leaking chimney myself, or do I need a professional?
DIY fixes like caulking or patching won’t solve the root cause of leaks in older masonry chimneys. Lacey’s climate demands proper repointing, flashing repair, or waterproofing, work best handled by a licensed chimney sweep. Attempting repairs yourself can trap moisture, leading to worse damage. For emergency leaks, call a specialist who understands brickwork and liner systems in older homes.
How much does it cost to repair a leaking chimney in Lacey? Will insurance cover it?
Costs vary based on the repair needed. Minor flashing fixes run $150–$400, while repointing or recapping can cost $800–$2,500 for a full chimney. Insurance may cover leaks if they’re due to storm damage or roof issues, but wear-and-tear repairs (like crumbling mortar) are usually excluded. Document the damage with photos and get a professional estimate before filing a claim. For older homes, preventive waterproofing can save money long-term.
