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 Cap & Crown in Woburn: What to Know First
We provide independent Olympia Chimney chimney cap and crown service in Woburn, with most jobs completed in a single visit and upfront pricing agreed before we start. A standard Olympia Chimney cap replacement runs $340-$620, while crown repair or coating typically falls between $280-$550 depending on access and flue count. We’re not here to sell you a full rebuild when a properly fitted cap or targeted crown repair will do.
This page is for homeowners in Woburn, Winchester, and the surrounding towns who have an Olympia Chimney system and need straight answers about what’s failing, what it costs, and who can fix it right. Call (781) 404-3793 - a live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 304 stainless single-flue caps: The mesh screen on these caps is spot-welded at stress points that fatigue after 8-12 winters in Woburn’s freeze-thaw cycle. We’ve pulled dozens off Montvale Avenue homes where the mesh has separated from the frame, letting squirrels nest directly in the flue. We replace with either an OEM Olympia cap or a Gelco equivalent with a continuous seam weld - whichever gives you better longevity for your specific exposure.
- Olympia Chimney multi-flue caps (galvanized and stainless): The galvanized models begin rusting at the corners where standing water collects, usually year six or seven. In Woburn, where roof pitches shed heavy snow loads onto the chimney shoulder, this accelerates. We upgrade to 304 or 316 stainless Olympia multi-flue caps, or source a Copperfield custom fit when the flue spacing is non-standard.
- Olympia Chimney wind-directional caps: The rotating collar seizes after prolonged exposure to coastal moisture that reaches inland during northeast storms. Once frozen, the cap either spins constantly (no draft control) or not at all (backdraft into the house). We disassemble, clean the bearing race, and if the collar is scored, replace with a new Olympia directional cap or a Famco stationary cap with built-in draft induction if the homeowner prefers less moving parts.
- Olympia Chimney crown wash on masonry chimneys: The factory crown coating is a Portland-based mix that shrinks away from the flue tile after repeated thermal cycling. We’ve seen this on colonial-era homes near Woburn Center where the original Olympia liner was retrofitted - the crown develops hairline cracks that channel water straight to the smoke chamber. We grind back to sound concrete, apply a HeatShield crown seal, and reset the flue tile gap with proper expansion joint material.
- Olympia Chimney chase covers on factory-built chimneys: The stamped steel covers on older Olympia factory-built systems sag in the center, creating a pond that rusts through from the inside out. Homeowners often don’t notice until water stains the ceiling below. We measure on-site and fabricate a replacement from 24-gauge stainless or copper, with cross-breaks welded in to shed water, not collect it.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, day or night. We book a window that works for you - no four-hour waits.
- 2
Level-2 camera inspection. Our tech arrives in uniform, background-checked, and runs a camera up the flue before touching the cap or crown. You see the footage. We explain what we see in plain English - no jargon, no scare tactics.
- 3
Parts decision with you. If your Olympia Chimney cap or crown needs replacement, we show you OEM versus quality aftermarket options (Gelco, Famco, Copperfield) with honest trade-offs on price, warranty, and lifespan. You choose. We don’t choose for you.
- 4
The repair. Most cap replacements and crown coatings complete in one visit. For custom caps or extensive crown rebuilds, we fabricate off-site and return within the week - we’ll be there when we say.
- 5
Post-repair test and documentation. We run the camera again, verify draft performance, and leave you with photos, a written verdict, and your 90-Day Done Right Promise - in writing, no arguing.
- 6
Cleanup and final walkthrough. We haul away the old cap, sweep the roof area, and you approve the work before we leave. The number on the estimate is the number on the invoice.

We’ve been working on chimneys in Woburn and the surrounding towns for over 42 years.

FAQs
No - as an independent Olympia Chimney service provider, we use OEM or compatible professional-grade parts and document our work to manufacturer standards. The warranty covers defects in materials and workmanship from the factory; routine service, cap replacement, and crown repair by a qualified technician do not affect it. If you have a specific warranty concern, we’ll review your documentation with you before starting work. Call (781) 404-3793 and we’ll sort it out.
A properly installed 304 stainless Olympia Chimney cap typically lasts 15-20 years in Woburn, though galvanized models show rust at the corners in 6-8 years due to our freeze-thaw cycle and road salt in the air. We inspect the weld points and mesh tension during every sweep and tell you honestly when replacement is worth it versus when it can wait. For an exact assessment of your cap’s condition, call (781) 404-3793 for a free estimate.
Most Olympia Chimney crowns with surface cracking or minor spalling can be coated with HeatShield crown seal after proper prep - that’s the $280-$420 range. We recommend full rebuild only when the concrete is crumbling, the rebar is exposed, or the crown has separated from the flue tile. Our camera inspection shows you exactly which category you’re in before you commit to anything. Call (781) 404-3793 and we’ll show you what we see.
We carry common Olympia Chimney single-flue and multi-flue cap sizes on our trucks for same-visit replacement. Uncommon sizes, wind-directional models, or custom chase covers we fabricate or order - typically 3-5 business days. We’ll tell you before we leave the first visit exactly what the timeline is and what temporary protection we can put in place if weather is coming. Call (781) 404-3793 to check availability for your model.
Water entering the flue, animals nesting, or visible rust holes in the cap are urgent - they lead to liner damage, smoke chamber deterioration, or blockages that create fire and carbon monoxide hazards. A slightly discolored or loose cap can usually wait until your scheduled sweep. We don’t invent urgency. Our camera inspection shows you the difference, and we’ll tell you plainly when work can safely wait. Call (781) 404-3793 for an honest assessment.
If the flue isn’t right, the fire isn’t safe - and there’s no shortcut around that. We’re here to do the job right the first time, document it so you can see it, and stand behind it so you don’t have to think about it again.
