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 Cap & Crown in Trenton: What to Know First
As an independent Olympia Chimney service provider in Trenton, we install, replace, and repair chimney caps and crowns on Olympia Chimney systems, with most jobs completed in a single visit and upfront pricing agreed before we start. A standard Olympia Chimney cap installation runs $280-$520; crown repair or coating typically falls between $340-$780 depending on access and masonry condition. We do not guess at what you need, we document it with camera inspection photos you can see yourself, and we back every job with our 90-Day Done Right Promise in writing.
This page is for Trenton homeowners who already have an Olympia Chimney liner, cap, or crown and need honest service from people who know the product line, not a hard sell. Call (856) 519-0832 - a live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney stainless caps with cross-break tops - the series with the stamped X-pattern lid common in 2015-2019 installs - trap leaf debris from Trenton’s heavy oak canopy where Chambersburg and Mill Hill neighborhoods meet. The cross-break channels water inward instead of shedding it, and the screen mesh corrodes at the weld points within six to eight years in our freeze-thaw climate. We replace with a Gelco or Olympia-equivalent cap with a true dome profile and 5/8-inch spark arrestor mesh, or fabricate a custom cap if your flue size is non-standard.
- Olympia Chimney multi-flue caps on older Trenton rowhouses - the kind spanning two or three flues on shared chimney stacks near Broad Street Station - sag at the center support bar after a decade of snow load. The galvanized undercarriage rusts from the inside out where homeowners cannot see it. We pull the cap, assess the flue wall integrity with a camera, and install a reinforced multi-flue cap with stainless cross-bracing and proper lead flashing to the masonry, not just caulk.
- Olympia Chimney crown wash on pre-2000 installs - the thin cementitious top layer Olympia applied as standard before they shifted to thicker pre-sloped crowns - cracks horizontally within five to seven years in Trenton’s climate. Water enters, freezes, and lifts the crown from the brick below. We grind back to sound concrete, apply a bonded crown coat with proper drip edge and slope, or pour a new cast-in-place crown if the substrate is too far gone. We do not skim-coat over rot.
- Olympia Chimney round caps on ovalized flue tiles - a mismatch we see in Hamilton Township and Ewing expansions where builders used Olympia liners with standard round caps on clay flues that have heated and distorted to oval over decades. The cap sits cockeyed, gaps open, and squirrels get in every spring. We measure the actual flue opening with a caliper, not eyeball it, and order or fabricate a cap that seats properly with an adjustable base flange.
- Olympia Chimney chase covers on factory-built chimneys - the stamped galvanized units with recessed center hole - pond water in the recess, then rust through at the fastener holes. By the time you see a ceiling stain, the wood framing below is often damaged. We replace with a stainless or copper chase cover with cross-break and proper storm collar, and we photo-document the framing condition so you know what you’re dealing with, not just what we’re selling.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, asks what you’re seeing, and books a time. We do not give a firm price over the phone without looking, because that is how surprises happen.
- 2
Level-2 camera inspection. Our technician runs a camera up the flue and across the crown surface, then shows you the photos on a tablet. You see what we see: cracks, rust, spalling, animal entry, or water damage. We explain what it means in plain English, not chimney jargon.
- 3
Parts decision. If your Olympia Chimney cap or crown is still under manufacturer warranty, we note that and use OEM-compatible parts so coverage stays intact. If warranty has lapsed, we source quality aftermarket from Gelco, Famco, or Copperfield, or fabricate custom - whichever fits your flue and your budget. We tell you the trade-offs straight.
- 4
Repair or replacement. Most cap swaps and crown coatings take two to four hours. We work from ladders and scaffolding, not by damaging your roof. Background-checked, uniformed technicians; no subcontractors you have never met.
- 5
Post-job test and documentation. We run the camera again to confirm proper clearances and draft, then give you a photo report, the written 90-Day Done Right Promise, and a final invoice matching the upfront estimate.
- 6
Cleanup and follow-up. We haul away the old cap or crown debris. If anything feels off in the next ninety days, we come back. No paperwork to find, no argument to have.

Why Trenton Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be here in thirty more. That changes how you treat a customer.
Our 90-Day Done Right Promise is in writing, no arguing - if it’s not right, we make it right. Russell Haines and our technicians know Olympia Chimney products from hands-on work in Trenton homes, not from a catalog. When an Olympia part is back-ordered or discontinued, we have relationships with DuraFlex, HeatShield, and Gelco to source compatible professional-grade alternatives that do not compromise safety or function. Most jobs finish in one visit. The number on the estimate is the number on the invoice.
If the chimney’s not right, the fire’s not safe. That’s the whole job.
FAQs
No, if the work is done with OEM-compatible parts and proper installation practices. As an independent Olympia Chimney service provider, we use parts and methods that maintain any remaining manufacturer coverage, and we document what was used so you have a record. If your warranty has already expired, we explain the aftermarket options that match or exceed original specs. Call (856) 519-0832 and we’ll check your install date.
A quality stainless Olympia Chimney cap lasts 12-18 years in Trenton’s climate if properly sized and maintained; galvanized versions often show rust at 6-10 years, especially under oak canopy debris loads. The freeze-thaw cycles and occasional ice storms we get in Mercer County accelerate wear on lesser materials. We inspect crown and cap together, because a failing crown kills even a good cap prematurely. Call for a free inspection - estimates cost nothing.
We reseal when the concrete substrate is sound and cracks are surface-level; we replace when the crown has lifted, spalled, or delaminated from the brick below. We determine this with a camera and a hammer test, not by guessing from the ground. We will not sell you a new crown if a quality coating will last. Call (856) 519-0832 for an honest verdict you can see in photos.
We stock common Olympia Chimney cap sizes and crown coating materials; specialty or custom items typically arrive within three to five business days. If your cap is leaking or animals are entering now, we can install a temporary secure cover while we order the permanent replacement. Most standard jobs still complete in a single visit. Call to confirm availability for your model.
Water in the firebox, rust stains on the damper, debris falling into the hearth, or draft problems that started suddenly usually point to cap or crown failure. But we have also traced “cap problems” to cracked flue liners or missing mortar joints that only a camera reveals. We inspect before we recommend. The $89 Seasonal Tune-Up includes a Level-1 inspection; if we find cap or crown issues, we apply that tune-up cost toward the repair. Call (856) 519-0832 to book.
