Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Repair Across Mountlake Terrace
Chimney repair in Mountlake Terrace usually means water getting in where it shouldn’t, not fire damage. Most homes here were built in the 1960s and 1970s, with short exterior chimneys that take the brunt of Puget Sound weather. Crowns crack, flashing rusts through, and water works its way down before you ever see a stain on the ceiling. We repair the full stack, from the crown at the top to the firebox below, and we put the price in writing before any work starts. Call (830) 251-4560 and a live person answers, day or night.
Why Flint Chimney Sweep Is Mountlake Terrace’s Preferred Chimney Repair Company
We’ve worked on enough Mountlake Terrace chimneys to know the pattern: the firebox is fine, but the crown and flashing at the roofline are failing. Hank Delano leads our team with a simple rule: nothing gets recommended without camera evidence the homeowner can see for themselves. Every job gets a written price before we touch a single brick, and every repair carries a 365-Day Done Right Promise in writing. If a covered repair fails within one year, we come back at no charge.
Our technicians are background-checked and uniformed, so you know exactly who’s walking through your door. Scheduling and dispatch are coordinated from the Seattle office, but our crews serve Mountlake Terrace directly and know the local housing stock well. We’ve repaired chimneys off 56th Ave W, near Forest Crest, and throughout the neighborhoods east of I-5. The same Garrison Standard applies to every call: documented scope, documented price, documented guarantee.
Chimney Flashing Repair in Mountlake Terrace
Chimney Flashing Repair is the most common repair call we handle in Mountlake Terrace, and it’s rarely urgent in the way homeowners fear. Flashing is the metal barrier where the chimney meets the roofline. On a short exterior chimney typical of a 1960s or 70s split-level, that flashing takes direct rain from every direction. After 20 to 30 years of wet-dry cycling, the metal corrodes, the sealant fails, and water finds its way into the attic or down the chimney chase. In Mountlake Terrace, a flashing repair typically runs $350 to $800 depending on how much metal needs replacing and whether the surrounding shingles have to be lifted.
Rusted-Through Flashing at the Roofline
When flashing rusts through, the fix is replacement, not caulk. A homeowner off 56th Ave W called us after seeing a stain on the ceiling near the chimney chase. The camera inspection showed rusted-through flashing at the roofline, feeding water into the smoke chamber below. We replaced the flashing with new metal and the stain never returned.
Lifted or Separated Flashing After Wind
Winter wind storms off Puget Sound can lift flashing that’s already loose. If you see a gap or daylight where the chimney meets the roof, water is getting in. We re-seat the flashing, replace any damaged sections, and re-seal the joint so it’s watertight again.
Chimney Crown Repair in Mountlake Terrace
Chimney Crown Repair in Mountlake Terrace is the second big one, and it’s the one homeowners rarely catch on their own. The crown is the concrete or mortar cap at the very top of the chimney. Its entire job is to shed water away from the flue. When it cracks, water wicks into the chimney structure and eventually into the smoke chamber, which is above the firebox and invisible without a camera. In Mountlake Terrace, crown repair typically runs $400 to $1,200 depending on whether we’re filling a hairline crack or rebuilding the entire cap.
Spalled Crown with Hairline Cracks
Spalling is the trade term for concrete surface flaking away, and it’s the first warning sign. A spalled crown with a hairline crack can look cosmetic while quietly feeding water down to the smoke chamber. We rebuild the crown with a proper crown-form pour or a crown coat system, then seal it so water can’t get back in.
Crown Repair Before the Rainy Season
If your crown cracks in October and you wait until spring, you’ve given water five months of direct access to the chimney structure. Mountlake Terrace’s drizzle pattern means water sits on the crown for days at a time. We recommend fixing a cracked crown before the next wet season, not after it.
Trusted Brands We Service in Mountlake Terrace
We spec materials by the job, not by the margin. When a Mountlake Terrace chimney needs a new flue liner, we work with Chimney Repair products like HeatShield and Olympia Chimney systems. For crowns and cap work, we use Gelco and Famco components. These are professional-grade materials from manufacturers that stand behind their product lines, and we maintain local stock so Mountlake Terrace customers aren’t waiting on a backordered part from across the country. If you want to verify what goes into your chimney before we order anything, ask and we’ll show you the spec.
Common Chimney Repair Problems We See in Mountlake Terrace Homes
- Failed flashing on short exterior chimneys. The roofline flashing on a 1960s split-level takes rain from every direction. After a few decades of wet-dry cycling, the metal corrodes and water gets in long before the firebox shows any wear.
- Spalled chimney crowns. Mountlake Terrace’s constant drizzle sits on concrete crowns for days at a time. Hairline cracks expand, water seeps into the smoke chamber, and the damage happens out of sight above the firebox.
- Missing or rusted chimney caps. Tree-heavy lots mean squirrels and rain get past a failed cap. The flue gets blocked, draft dies, and homeowners often assume the damper is the problem when the real issue is at the top of the stack.
- Glazed creosote from low-burn fires. Homeowners who burn only a few cords a year still build creosote. First-degree creosote brushes off easily. Glazed third-degree creosote is hardened and requires mechanical removal, and it’s a chimney fire risk.
Pricing for Chimney Repair in Mountlake Terrace, WA
Here are the ranges we typically see in Mountlake Terrace. Flashing repair runs $350 to $800. Crown repair runs $400 to $1,200.

FAQs About Chimney Repair in Mountlake Terrace
Yes, because the risk here isn’t creosote volume, it’s water intrusion you can’t see. Even if you burn a few fires a year, your crown and flashing are exposed to Puget Sound weather every single day. An annual Level 1 inspection catches a hairline crown crack before it becomes a $1,200 rebuild instead of a $400 patch. Call (830) 251-4560 to book one, and we’ll show you the camera images along the way.
A Level 1 is a visual check of the readily accessible parts of the chimney, done during a routine sweep. A Level 2 adds camera inspection of the flue interior and is required when you’re buying or selling a home, after a chimney fire, or when a weather event may have damaged the structure. A Level 3 is invasive, opening up walls or masonry to access hidden areas, and is only needed when a Level 2 finds something that requires it. For most Mountlake Terrace repair quotes, a Level 2 is what we recommend, because the water damage here hides above the firebox where a Level 1 can’t see it.
First-degree creosote is a light, flaky soot that brushes off easily. Second-degree is a crunchy, granular buildup. Third-degree is the glazed, shiny, tar-like coating that forms when flue temperatures stay low and the creosote bakes on. You can sometimes see third-degree creosote as a shiny black glaze if you shine a flashlight up the flue, but the reliable way to know is a camera inspection. We’ll show you the footage and tell you exactly what needs to happen. Call (830) 251-4560 for a free estimate.
If the crack is hairline and the rainy season hasn’t started, you have some time. If it’s October and the crack is open, water is going to sit in it all winter, and every freeze-thaw cycle widens it. The cost to patch a hairline crack now is a few hundred dollars. The cost to rebuild a spalled crown after a full wet season is easily double that. In Mountlake Terrace’s drizzle, we recommend fixing it before the next wet stretch. Call (830) 251-4560 and we’ll give you a straight answer on what can wait and what can’t.
Yes. Every repair quote in Mountlake Terrace includes a camera inspection of the flue and the areas we can access, and we give you a photo report showing exactly what we found. If we recommend a repair, you’ll see the evidence for it before we ask you to spend a dollar. If we don’t find anything worth fixing, we’ll tell you that too.
