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.

AfterOlympia Chimney Chimney Repair in Waltham: What to Know First
We provide independent Olympia Chimney chimney repair in Waltham, with most jobs completed in a single visit and upfront pricing agreed before we start. Typical turnaround from call to completion is three to five days during peak season, faster when weather permits. We do not sell parts you do not need, and we do not recommend work without camera evidence you can see for yourself.
This page is for Waltham homeowners who have an Olympia Chimney liner, cap, or component showing signs of trouble - spalling brick near the top, water in the firebox, or a crown that has started to crack. Russell Haines and our team have been working on chimneys across Waltham for over 42 years, including plenty of older colonials near the Moody Street corridor where Olympia Chimney liners were installed during the 1990s and 2000s renovation wave. If you are unsure what you are looking at, call (781) 905-8338. A live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney stainless steel liner collars loosen in freeze-thaw cycles. The 316Ti flexible liners, common in Waltham’s 1920s bungalows with offset flues, use a compression-fit collar at the thimble that can work loose after five to seven Massachusetts winters. We remove the collar, inspect the surrounding brick for spalling, and reinstall with a proper high-temp sealant and mechanical fastening - not just torque, which is what fails.
- Olympia Chimney Gelco-compatible caps corrode at the weld seams. The mid-grade galvanized caps sold under the Olympia Chimney umbrella in the early 2000s were built to Gelco specs but with lighter gauge material. In Waltham, where the Charles River valley holds humidity against north-facing chimneys, we see seam rust at year eight or nine. We replace with current-spec Gelco stainless or copper, matched to the flue count and properly counter-flashed.
- Olympia Chimney’s square clay flue adapters crack in rapid heat-up. The square-to-round adapters used with their ovalized flexible liners do not tolerate the thermal shock of a cold-start fireplace loaded with pine. We find hairline fractures running corner to corner, which vent combustion gases into the chimney cavity. Our fix: remove the adapter, inspect the surrounding terra cotta with a camera, and replace with a HeatShield-compatible transition or a properly sized DuraFlex direct-connect plate.
- Olympia Chimney crown-forming mortar shrinks and pulls from the brick. Their pre-mixed crown repair compound, applied by some Waltham roofers in the 2010s, lacks the polymer content to bridge the thermal expansion gap between brick and flue tile. We grind out the failed material, repoint the underlying brick if needed, and pour a proper Portland-based crown with expansion joint - or apply HeatShield CrownCoat if the substrate is sound but the surface is compromised.
- Olympia Chimney chase cover screw holes wallow out in aluminum construction. The factory chase covers on prefab units, especially the 304-aluminum series installed in Waltham’s 1980s and 1990s split-levels, use self-tapping screws that loosen as the aluminum fatigues. Water follows the screw threads into the chase. We replace with a heavier-gauge Copperfield stainless cover, using riveted standoffs and butyl tape - never reusing the original fastener holes.
Our Olympia Chimney Chimney Repair Process
- 1
Call and schedule. A live person answers, day or night. We ask what you are seeing, when it started, and whether you have the original installation paperwork. We book a two-hour arrival window.
- 2
Level-2 camera inspection. Our technician arrives in uniform, background-checked, and sets up a closed-circuit camera before touching tools. You see the footage in real time. We document cracks, gaps, liner displacement, or water intrusion with photos.
- 3
Plain-English verdict and upfront pricing. Russell Haines or the lead technician explains what is wrong, what can wait, and what cannot. We give a written estimate with one number - the number on the invoice. No surprises.
- 4
Parts decision: OEM or quality aftermarket. For Olympia Chimney components, we source factory-spec parts when they are available and make sense. When lead times stretch or the original part has a known weakness, we substitute professional-grade equivalents from DuraFlex, HeatShield, or Gelco - always disclosed, never hidden.
- 5
The repair and live test. We complete most jobs in a single visit. After the repair, we run a combustion spillage test or a water-mist simulation to confirm the fix holds under real conditions.
- 6
Cleanup, documentation, and guarantee. You receive photos, the inspection report, and the 90-Day Done Right Promise in writing. If it is not right, we come back. No paperwork, no arguing.

Why Waltham Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We are not a price-cutting chain, and we are not a one-truck operator who might answer the phone next year. We have been in business since 1984 - over 42 years - and we plan to be here when your Olympia Chimney liner needs its next inspection.
Our technicians know the difference between a 316Ti flexible liner and a 304-aluminum chase cover because they have replaced both, dozens of times, in Waltham homes. We carry DuraFlex, HeatShield, Gelco, and Copperfield materials on our trucks, so we are not waiting on a parts run while your chimney sits open. The 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing.
If the flue is clear and the crown is sound, you will not hear from me until next season. That is the goal.
FAQs
Using an independent service provider like Hearthstone Chimney Co. does not automatically void an Olympia Chimney warranty, but warranty coverage for the liner itself typically requires proof of proper installation and annual inspection by a CSIA-certified sweep. We document every inspection to that standard, and we will flag any issue that should still be under manufacturer coverage so you can pursue it. Call (781) 905-8338 if you are unsure about your warranty status - we will help you sort it out.
We source OEM Olympia Chimney parts when they are available and when the original design is sound. For components with known weaknesses - the early-2000s galvanized cap line, for example - we substitute professional-grade equivalents from Gelco or Copperfield and tell you exactly what we are doing. No hidden swaps. We are an independent Olympia Chimney service provider, not an authorized dealer, so we choose parts based on what lasts, not what moves inventory.
Replacement becomes necessary when the liner has separated, the clay flue is shattered in multiple courses, or the chimney structure itself is leaning. Most Olympia Chimney issues we see in Waltham - collar leaks, crown cracks, cap rust - are repairable at a fraction of replacement cost. We make that call with camera evidence you can see, not a sales pitch. If work can safely wait a season, we will say so.
Once a year, without exception, per NFPA 211. In Waltham, where oak and maple are common firewood and homeowners tend to burn three to four evenings a week in season, creosote buildup and thermal cycling stress the system faster than occasional use. Annual inspection catches collar loosening, cap corrosion, and crown shrinkage before water or gases find a path into your home. Call (781) 905-8338 to schedule - estimates are free.
Depending on what is wrong, you risk a chimney fire from creosote ignition, carbon monoxide intrusion through a cracked flue or loose collar, or accelerated brick spalling from water infiltration that turns a $400 repair into a $4,000 rebuild. We do not use scare tactics - we show you the photos and explain the odds. Some issues are genuinely urgent. Others can wait until spring. We will tell you which is which.
