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.

AfterDuraFlex Chimney Cap & Crown in Toms River: What to Know First
As an independent DuraFlex service provider, Hearthstone Chimney Co. installs, repairs, and replaces DuraFlex chimney caps and crowns across Toms River and Ocean County. Most DuraFlex cap and crown jobs are completed in a single visit, with upfront pricing agreed before we start. We do not sell what you do not need, and we document every recommendation with photos you can see for yourself.
This page is for homeowners who already have a DuraFlex system in place and need cap or crown work done correctly the first time. If you are unsure which DuraFlex line you have, we will identify it during inspection. Call (609) 303-9679 anytime, day or night. A live person answers.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW 304 and 316 stainless liners - The flex sections terminate with a top plate and cap assembly that sees constant thermal cycling. In Toms River’s coastal climate, salt air accelerates crevice corrosion at the cap-to-plate joint, especially on north-facing chimneys. We remove the assembly, inspect the flex termination for integrity, and replace with either OEM DuraFlex hardware or a Gelco marine-grade cap if the homeowner prefers upgraded corrosion resistance.
- DuraFlex Pro and Pro XL smooth-wall liners - These systems use a specific top-sealing damper and cap combo. The damper cable housing passes through the crown, and the seal point is a known entry path for water once crown mortar develops hairline cracks. We do not just caulk over the crack. We open the crown, reseal the cable penetration with a proper flashing boot, and rebuild the crown with HeatShield CrownSeal or a poured concrete crown depending on damage depth.
- DuraFlex oval-to-round adapters with factory caps - The adapter collar can loosen from expansion stress, letting the cap sit crooked or detach in high wind. This is common in Toms River after nor’easters. We check the adapter weld points, reseat with stainless draw bands, and install a wind-rated cap with reinforced mesh if the factory mesh has collapsed from creosote weight or corrosion.
- DuraFlex relining jobs with poured insulation - The crown must be removed to pour the insulation mix, and the reinstall is where corners get cut. We have found crowns that were never properly resealed after DuraFlex installation by other contractors, leaving a gap between the crown edge and the flue tile. Our fix: remove the crown, verify the pour is intact, and reinstall with a proper drip edge and bond break to prevent future cracking.
- DuraFlex tee and cleanout assemblies - The tee cap (not the top cap) is often overlooked. In Toms River’s older homes, especially in Silverton and parts of North Dover, the tee cap rusts through or the cleanout door seal fails. Smoke and moisture back-vent into the basement. We replace with DuraFlex-compatible tee caps or, when the tee body itself is corroded, source an exact-match replacement from Olympia Chimney supply.
Our DuraFlex Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask about your DuraFlex system if you know it, or we will identify it on site.

Level-2 camera inspection. Our technician runs a camera the full length of the flue, photographs the cap, crown, and flex termination, and explains what we see in plain English. You see the photos. The flue doesn’t lie. Neither do we.
- 3
Parts decision. We stock common DuraFlex caps, crowns, and hardware. For specialty items, we source from our supply chain, typically next-day. We discuss OEM versus quality aftermarket options, including warranty implications, and you decide.
- 4
Upfront pricing and approval. We give you one number. That is the number on the invoice. No surprises.
- 5
The repair. Background-checked, uniformed technicians complete most DuraFlex cap and crown jobs in a single visit. We use professional-grade materials, no builder-grade substitutes.
- 6
Test and document. We run a final camera pass, test draft and spillage, and leave you with photos, a written report, and the 90-Day Done Right Promise in writing. If it is not right, we come back. No arguing.

Why Toms River Homeowners Call Hearthstone Chimney Co. for DuraFlex 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 served Ocean County for over 42 years, and we plan to be here in thirty more. That changes how we work.
Our technicians know DuraFlex systems specifically, not just chimneys in general. When a DuraFlex Pro XL damper cable has seized, or a 316 flex cap has corroded through at the collar, we have seen it before. We also work with HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, so if a DuraFlex part is back-ordered or a different brand suits your situation better, we can source it without delay.
The 90-Day Done Right Promise is in writing. If it is not right, we make it right. No paperwork to find, no arguing. Photos you can see. A plain-English verdict. A square deal: no surprises on the bill. That is the Keystone Standard.
FAQs
No, if the work is done correctly using compatible parts and proper clearances. As an independent DuraFlex service provider, we follow manufacturer specifications for termination height, mesh sizing, and insulation exposure. We document our work with photos in case warranty questions arise later. If you have a specific concern about your DuraFlex warranty terms, bring the paperwork and we will review it together. Call (609) 303-9679.
If water is entering the flue but the cap itself is intact, level, and properly seated, the crown is likely the culprit. If the cap is missing, rusted through, has collapsed mesh, or sits crooked, the cap needs replacement and the crown may need attention too. Our camera inspection shows you exactly which is which. We do not guess, and we do not sell both if you only need one. Call (609) 303-9679 for a free inspection.
We stock the most common DuraFlex caps, top plates, and hardware at our Ocean County facility. Specialty items, such as custom multi-flue caps or specific 316-grade components, typically arrive next business day from our supply chain. We do not start a job until the correct part is in hand. If DuraFlex back-orders an item, we will discuss a quality aftermarket alternative from Gelco or Olympia Chimney and let you decide.
A crown with surface cracking and minor spalling can often be saved with HeatShield CrownSeal, which we apply after proper prep. If the crown has separated from the flue tile, has through-cracks allowing water into the chase, or has lost more than an inch of structural thickness, replacement is the honest recommendation. We show you the photos and explain which category you are in. Call (609) 303-9679 for an exact assessment.
Once per year, before burning season. Toms River’s coastal environment, with salt air and freeze-thaw cycles, accelerates wear on both cap and crown. An annual Level-2 inspection catches crown hairline cracks before they become leaks, and cap corrosion before it becomes a flue obstruction. We offer an $89 Seasonal Tune-Up that includes this inspection. Call (609) 303-9679 to schedule.
