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.
Olympia Chimney Chimney Repair in Crystal Lake: What to Know First
We provide independent Olympia Chimney chimney repair in Crystal Lake for homeowners with Olympia liners, caps, and flashing systems that have cracked, pulled, or leaked. Most Olympia Chimney jobs in Crystal Lake are diagnosed and quoted within a single visit, with a written price delivered before any work starts and a documented photo record saved to your file. We’re not affiliated with or authorized by Olympia Chimney - we work on their products as an independent Olympia Chimney service provider, sourcing parts through our Haven buying network to keep pricing honest. If your flue liner is showing gaps, your crown is spalling, or water is coming through the flashing, call (815) 923-3185. We’ll get a camera down there and show you exactly what’s wrong.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney stainless steel liner collars separate at the seam in the 316Ti series after 8-12 winters of Crystal Lake’s freeze-thaw cycling. The collar joint was designed with a single-lock seam that opens when water gets behind it and expands. We cut back to sound metal, install a new collar with a double-lock mechanical seam, and seal with Haven-spec high-temp silicone rated to 600°F.
- Olympia Chimney Gelco-compatible caps corrode at the mesh weld points on models sold between 2015 and 2019, particularly the Gelco 3/4-inch mesh line. The galvanic reaction between the stainless mesh and the powder-coated frame accelerates in McHenry County’s limestone-heavy rainwater. We source direct-fit replacement mesh from our Famco and Gelco supply chain, or spec a full cap upgrade if the frame itself is pitted.
- Olympia Chimney DuraFlex relining sleeves slip at the connection in the DuraFlex 30° and 45° elbow kits when the original installer didn’t use the manufacturer’s locking band torque spec. We find this on homes near Three Oaks Recreation Area where the older masonry shifts seasonally. Our fix: remove the sleeve, inspect the surrounding flue tile for hidden cracks, reinstall with fresh locking bands torqued to 60 in-lbs, and photo-document the engagement.
- Olympia Chimney crown-forming mortar cracks vertically on poured crowns that used their pre-mix product in applications under 2 inches thick. The mix is high-compression but low-flex; Crystal Lake’s January temperature swings from 35°F to -10°F in a week create shear stress. We grind out the crack, repoint with HeatShield CrownSeal (a flexible membrane system), and feather the edge so water runs off instead of pooling.
- Olympia Chimney step flashing lifts at the mortar joint on brick chimneys where their L-shaped galvanized was bedded directly into soft lime mortar. The mortar erodes, the flashing tilts, and water tracks behind the brick face - we see this pattern on 1960s and 1970s homes off Route 14. We remove the course, install new copper or stainless step flashing with a reglet joint into the chimney, and repoint with Type N mortar matched to the existing hardness.
Our Olympia Chimney Chimney Repair Process

- 1
Call and schedule. A live person answers 24/7. We ask the age of your Olympia Chimney component, the symptoms you’ve noticed, and whether you’ve had prior camera work done. We assign a named technician and text you when they’re en route.
- 2
NFPA 211 Level 2 inspection. Our tech runs a camera the full length of the flue, photographs every joint, seam, and transition, and records liner diameter and condition readings. Clause 4 of the Haven Standard requires this photo record on every job - we started that practice in 2009.
- 3
Written price, written scope, written warranty. Before any tool touches your chimney, you get a single-page document with line-item costs, the exact Olympia Chimney or compatible parts we’ll use, and the 365-Day Done Right Promise. Haven Standard Clause 1: have it in writing.
- 4
Repair with documented steps. We photograph before, during, and after. If we’re using Olympia Chimney OEM parts, the part number is logged. If we’re substituting a DuraFlex, HeatShield, or Gelco equivalent, we note the specification match and why it was selected.
- 5
Post-repair camera verification. The camera goes back down to confirm the fix - liner continuity test, smoke test for drafting, visual confirmation of crown or flashing integrity. The photos go into your permanent file.
- 6
Cleanup and record delivery. We leave the work area as we found it. You receive a printed summary, the photo archive link, and our direct line if anything doesn’t look right. The camera doesn’t argue - and neither does a written price.

Why Crystal Lake Homeowners Call Level Two Chimney Crystal Lake for Olympia Chimney Work

We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and the ones in Crystal Lake have taught us something specific: Olympia Chimney products installed in the 2015-2020 window tend to show the same four failure patterns, and guessing wastes everyone’s time. Our technicians are background-checked, uniformed, and assigned by name - you’ll know who’s coming, and they’ll know what Olympia Chimney series is in your flue before they arrive.
Because we buy DuraFlex, HeatShield, Gelco, and Olympia Chimney materials through the Haven buying network, we’re not locked into a single manufacturer’s markup. If your Olympia liner can be repaired with a quality aftermarket equivalent that meets the same UL 1777 spec, we’ll show you both options in writing. And if a competitor has already written you an estimate for Olympia Chimney work, bring it in - our Free Second Opinion is exactly that, free, with no pressure to switch.
The 365-Day Done Right Promise applies to every repair. If the fix doesn’t hold, we make it right. That’s not a slogan - it’s stamped on every job under the Haven Standard.
FAQs
No, independent repair by a qualified technician does not automatically void an Olympia Chimney liner warranty, provided the work uses compatible materials and does not alter the original specification. We document every part number and specification match so your warranty record stays clean. Call (815) 923-3185 if you need help understanding your specific warranty terms.
Yes - we source Olympia Chimney-compatible components through our Haven buying network, including direct OEM and cross-referenced equivalents from DuraFlex, HeatShield, and Gelco. For discontinued series, we fabricate or adapt using documented equivalents that meet the same UL and ASTM standards. Call (815) 923-3185 and we’ll confirm parts availability for your specific model.
The camera decides, not us. If the liner shows isolated seam separation, collar failure, or minor spalling, repair is usually the honest call. If we find multiple seam failures, wall thinning below 0.012 inch in stainless, or hidden flue tile collapse behind the liner, we’ll show you the footage and quote both repair and replacement so you can decide. Call (815) 923-3185 to schedule the inspection.
Most single-component repairs - collar, cap, flashing section - are completed in one visit of 2-4 hours after the inspection. Crown rebuilds or partial chimney rebuilds may require a return visit for proper cure time between stages. We quote the full timeline in writing before starting, with no open-ended “we’ll see how it goes.” Call (815) 923-3185 to book.
A separated liner collar or lifted flashing lets water and combustion gases into spaces they shouldn’t reach. In Crystal Lake’s freeze-thaw climate, water behind brick accelerates spalling and can open gaps that draw carbon monoxide into wall cavities. The risk is real, but so is the cost of unnecessary work - that’s why we camera-inspect first and show you exactly what’s urgent and what can wait. Call (815) 923-3185 for a free estimate.
