Chimney leaks in Mill Creek usually announce themselves as a brown stain on the ceiling beside the fireplace, a musty smell in the chase, or water dripping onto the firebox during a November storm. On the prefab chimneys that dominate Mill Creek and Silver Firs, the water typically comes from one of three places: a chase cover that has rusted through or ponded, a storm collar that has lost its seal around the pipe, or step flashing where the chase meets the roof. On the brick chimneys here, the culprit is more often a cracked crown or porous mortar joints. We check all of them before we quote, because fixing the wrong one is how a leak comes back.
We come out from Renton in roughly 40 minutes and give you a free quote on the actual repair, whether that is a chase cover starting at $299, a crown rebuild starting at $299, or flashing and sealant work. If a roofer or another chimney company already quoted the leak, we will give a free second opinion and price match plus 10-25% off. Our guarantee is simple: if you are not happy and the leak is not gone, we are not done, and we come back at no charge. We are certified and insured and use safe, green materials.

- Damp firebox walls even when it has not rained for a day or two
Mill Creek Conditions
Why this happens in Mill Creek
Mill Creek gets the full Puget Sound wet season. Sea-Tac normals show 40.34 inches of precipitation a year, with about 73 percent of it between October and March and November the wettest month at 6.31 inches. A chase cover with a slight dip or a storm collar with a hairline gap will shrug off summer, when June through August total only about 3 inches, and then leak every week once the rain returns. That is why most Mill Creek leak calls come in the first wet month, after the fireplace has sat unused all summer.
Shade makes it worse. Mill Creek's tree canopy keeps chimney tops damp, and regional roofing guidance notes that moss spreads fastest October through April on shaded, slow-drying surfaces. Moss on a crown or cover holds water against it. With around 60 days a year touching 32F and winter lows averaging near 37F, that trapped water typically freezes and thaws many times, widening the crack or rust hole a little more each cycle until the drip shows up inside.
How It Works
Our chimney leak repair process
Map the symptom
We ask where the water shows up, when, and how long after rain, because each entry point leaves a different signature.
Check the top
Crown, cap and chase cover are inspected first, since they are the most common leak sources and the fastest to rule in or out.
Check the roofline and masonry
Flashing, mortar joints, spalled brick and the flue itself are checked, including for condensation that mimics a leak.
Fix in the right order
We repair the entry points that are actually leaking, from the top down, and leave the sound ones alone.
Water-test and follow up
Where possible we run water on the repair to confirm it is dry, and if the next storm proves us wrong, we come back at no charge.

Chimney Leak Repair in Mill Creek — FAQ
The ceiling next to my Mill Creek fireplace is stained. Is it the roof or the chimney?
On Mill Creek's framed chases it is usually the chimney side: a rusted chase cover, a failed storm collar or the flashing where the chase meets the roof. We inspect all three before quoting so you are not paying a roofer for a chimney problem. The quote is free and we can often come the same day.
Can you fix a chimney leak in Mill Creek during the rainy season?
Yes. We replace chase covers, reseal storm collars and rebuild crowns year round, working between storms when the surface needs to be dry for sealant or crown material to cure. If a leak is active we can typically stop the water the first visit and finish the permanent repair as weather allows, all under our free-quote, price-match pricing.
How soon can you do chimney leak repair in Mill Creek?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Mill Creek and the rest of Snohomish County.
