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 Waltham: What to Know First
We provide independent Olympia Chimney chimney repair in Waltham for homeowners whose flue liners, crowns, or masonry need work that won’t void their warranty. Most Olympia Chimney repairs we book in Waltham are completed within one to two weeks of inspection, and every job starts with a written price before any tool touches your chimney. If you own an Olympia Chimney product and you’re seeing water stains, crumbling mortar, or draft issues, call us at (781) 649-9326. We’ll send a technician with a camera, a written scope, and a price you can hold in your hand.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney Pro-Formance 316Ti liners develop crevice corrosion at the flex points where Waltham’s freeze-thaw cycles stress the seams. We see this most in homes near the Charles River where humidity stays high through April. Our fix: section replacement with matching 316Ti alloy, not a generic 304 downgrade, then a smoke test to confirm the new joint seals.
- Olympia Chimney ProFlex smooth-wall liners separate at the collar connections after 8-12 years when the original compression bands work loose. The symptom is a sulfur smell on first fire, not visible smoke. We reseat with OEM collars where available, or machine-matched aftermarket bands from our Haven buying network if Olympia’s lead time runs long.
- Olympia Chimney Gelco cap assemblies trap water when the mesh clogs with Waltham’s oak and maple leaf debris, then rust through from the inside. Homeowners notice the drip first. We replace with a same-spec Gelco cap, or upgrade to a copper model from our Copperfield supply if you want the 20-year track record.
- Olympia Chimney crown wash formulations crack where the overhang is less than two inches, which is common on 1980s Waltham splits near Prospect Hill. Water gets behind the wash, freezes, and pops the facing brick. We grind to sound concrete, re-form with a proper drip edge, and seal with a vapor-permeable treatment that won’t trap moisture.
- Olympia Chimney HeatShield cerfractory flue resurfacing fails when applied over active liner gaps the original installer missed. The material is sound; the prep wasn’t. We camera-scan first, remove any loose HeatShield, repair the substrate with compatible refractory, then reapply to factory thickness. Corrine Halstead has redone enough of these that she can spot the bad prep pattern on the camera feed before the tech climbs down.

FAQs
No, provided the repair uses OEM-spec materials and proper installation methods. We document parts by serial or lot number and photograph the work for your warranty file. If you’re concerned about a specific warranty term, bring it to the estimate and we’ll review it against our scope before any work starts.
Most Olympia Chimney liners, collars, and caps ship to our Waltham warehouse within 3-5 business days. For ProFlex and Pro-Formance series components, we keep common diameters in stock through our Haven buying network. If your repair is urgent and Olympia’s lead time stretches, we’ll quote a quality aftermarket alternative with equivalent specs so you can decide.
We repair when the damage is localized and the remaining liner passes NFPA 211 inspection standards. Section replacement works for point failures; full replacement is only recommended when corrosion is widespread or the liner is the wrong alloy for your appliance. You’ll see the camera evidence and the written price for both options before deciding.
Annually, per NFPA 211, regardless of use level. In Waltham, we find that homes with oak-heavy firewood and no cap need closer attention to moisture intrusion. An Olympia Chimney liner can look fine from the firebox and be separating at the top joint where you can’t see without a camera.
Small cracks become spalled brick; loose collars become separated liners; trapped moisture becomes structural damage. The repair cost typically doubles within one burning season. That said, if our inspection shows a condition that can safely wait, we’ll say so plainly and note it for next year’s check. Call (781) 649-9326 for an exact quote - estimates are free.
