Most Reliable Chimney & Fireplace Services company for Homeowners Throughout King County Since 2011.
The Official Recommendation: Once a Year
The Chimney Safety Institute of America (CSIA) and the National Fire Protection Association (NFPA 211) both recommend that chimneys be inspected and cleaned at least once per year, regardless of how frequently you use your fireplace. This applies to wood-burning fireplaces, gas fireplaces, and wood stoves.
When You Should Clean More Often
Annual cleaning is a minimum, some situations call for more frequent service:
- Heavy use (3+ fires per week during burning season)
- Burning unseasoned or "green" wood, which produces 3 to 5x more creosote
- Slow, smoldering fires rather than hot, bright fires
- You notice slow drafting, smoke backing into the room, or strong odors
- Visible soot or creosote buildup on the firebox walls or damper
- You've had a chimney fire (requires immediate inspection and cleaning)
Understanding Creosote: Why Cleaning Matters
Creosote is the primary reason chimney cleaning is necessary. It's a flammable byproduct of wood combustion that accumulates on flue walls over time. Creosote comes in three stages: Stage 1 (light, dusty deposits, easy to remove), Stage 2 (flaky, crunchy buildup, harder to remove), and Stage 3 (tar-like glazed coating, extremely difficult and dangerous). Stage 3 creosote is the leading cause of chimney fires, which burn at temperatures exceeding 2,000°F.
Even one inch of Stage 3 creosote can ignite and cause a chimney fire that spreads to your home structure. Don't wait for symptoms, annual cleaning is prevention.
Gas Fireplace Cleaning Schedule
Gas fireplaces produce significantly less residue than wood-burning units, but they still need professional service. The CSIA recommends gas fireplace inspection every 1 to 2 years. Technicians check the burner, pilot assembly, venting, glass seal, and gas valve, issues that aren't visible to homeowners but can pose serious safety risks.
What Happens During a Professional Chimney Cleaning
- Protective drop cloths placed from entry to fireplace
- Industrial HEPA vacuum connected to fireplace opening
- Professional rotary brushes scrub the entire flue length
- Smoke shelf and damper thoroughly cleaned and inspected
- Firebox vacuumed and brushed clean
- Basic visual inspection of accessible components
- Before/after photos provided
- Cleaning certificate issued for insurance documentation
Best Time of Year for Chimney Cleaning in Seattle
The ideal time to schedule chimney cleaning in the Seattle area is late summer or early fall, August through October, before the burning season begins. This ensures your chimney is clean and safe before you need it, avoids the rush when weather turns cold, and allows time to address any repairs found during the inspection before you need the fireplace.
Schedule your cleaning before October to avoid the fall rush. Call (206) 430-0323, we serve Seattle, Renton, Bellevue, Kent, and all of King County.

What Homeowners Are Saying
"Shawn gave an estimate and quickly scheduled the cleaning. He did a great job and answered all our questions about fire safety and chimney maintenance!"
"We had a really bad experience with another contractor who took our money and left us with an unfinished and unsafe chimney. We were nervous about hiring someone else after that, but Chimney Pro Solutions made the whole process completely different. They took the time to explain what was wrong, showed us exactly what needed to be rebuilt, and were very clear about the work from the beginning. Their team rebuilt our chimney professionally, kept us updated throughout the project, and made sure everything was completed properly. After what we went through before, it was a huge relief to finally work with a company that was honest, reliable, and stood behind their work. We’re very happy with the rebuild and would definitely recommend them."
"I had a great experience with Chimney Pro Solutions. They were always responsive and willing to work with our schedule. I had a lot of difficulty with other chimney places getting a response or working with my schedule, but these folks actually care about their work and were always respectful and commutative from David responding to my emails and Sean doing the work and texting with updates. If you need high quality chimney services these are your folks! The photos of the before and after work speak for themselves so go ahead and give them a call!"
"Listen, when I tell you, Sean from Chimney Pro solutions is a good dude, I can’t stress it enough. He came out to assess my fireplace and chimney in March after we were smelling smoke in the house days after having a fire. He found my firebox was looking a little rough and that there was a solid amount of creosote in the chimney. He gave me several options for remediation/repair. Due to family emergency I had to leave town for several months. I wound up having reschedule repair service three times and he couldn’t have been more gracious and understanding. As for the service, he did a beautiful job. I didn’t realize how gross my fireplace was. It looks brand new and is safe to use. Plus he was meticulous about cleaning up after himself. I told him he’ll be our first call when it comes time for roof repair! Call these guys!!"
"We recently had Chimney Pro Solutions repair our chimney in Seattle after noticing cracks and water leaks around the fireplace. Sean explained everything clearly, showed us photos of the damage, and the crew did an amazing job with the repairs. The chimney looks great now and we feel much safer using our fireplace. Highly recommend!"
"Excellent experience replacing our old gas fireplace with a new one! The team was professional, efficient, and did a beautiful job with the installation. Everything works perfectly, and the new fireplace looks amazing. Great communication, clean workmanship, and overall outstanding service. Highly recommend!"
"We had our chimney inspected last Tuesday and it was repaired today, such a fast turnaround from our technician, Yuval. He was knowledgeable, professional, and took the time to clearly explain what needed to be done without any unnecessary upselling. The cost was also very reasonable. We highly recommend Chimney Pro Solution if you need chimney services. After dealing with concerns about our chimney, it was a relief to have everything handled quickly and professionally. We now have real peace of mind."
"Chimney Pro solutions came out to inspect my gas fireplace. They was really thorough and professional! Will definitely suggest them to friends and family."
