This page is for Hempstead homeowners who have an Olympia Chimney fireplace, wood stove, or liner system and want to understand the repair realities specific to that equipment. Hank Delano has been running chimney crews across Nassau County for the better part of two decades, and he still takes the calls himself.
How Olympia Chimney Products Fail – and How We Fix Them
Olympia Chimney builds solid equipment. But years of Hempstead weather cycles, salt air from the south shore, and wood-burning habits reveal patterns. Here are the five failure points we see most often on Olympia Chimney systems in Hempstead homes.
- Olympia Chimney stainless steel liners with corroded seams. We regularly find Olympia flexible liners in Hempstead homes where the seam weld has thinned from years of acidic creosote. The symptom is usually a faint smoky smell in the house even when the damper is closed. The real cause is not the liner material itself but moisture combining with creosote inside. We inspect with a camera, and if the liner wall has lost thickness, we replace it rather than patch it. Patches on a liner seam are temporary and we won’t sell you one.
- Mortar joint erosion on Olympia Chimney masonry systems. Hempstead gets roughly 45 inches of rain a year plus winter freeze-thaw cycles, and that combination works mortar loose over time. We see this most on Olympia Chimney installations tied into older brick chimneys, where the original mortar was softer than the modern product. We repoint with mortar matched to the existing joint profile and strength, not just whatever mix is cheapest.
- Flashing separation at the roofline. A chimney flashing leak on an Olympia Chimney system in Hempstead is almost never the flashing’s fault. It’s the sealant that dried and cracked. We strip the old caulk, reset the flashing, and use a polyurethane sealant that flexes with Nassau County’s temperature swings. A tube of caulk from the hardware store will not fix this for more than one season.
- Spalled brick faces from trapped moisture. Spalling is when the brick face pops off, and once it starts on an Olympia Chimney chimney in Hempstead, it does not stop on its own. The usual culprit is a failed or missing chimney cap letting water saturate the brick. We replace the damaged brick, address the water entry point, and apply a breathable water repellent when the brick can handle it.
- Cracked crown on the chimney top. The crown is the concrete cap that sheds water off the top of the chimney. On older Olympia Chimney systems in Hempstead, we see crowns cracked from years of expansion and contraction. Water gets through the crack, runs down the flue walls, and the damage compounds. We rebuild crowns with a slight slope away from the flue and a drip edge, so water goes where it belongs.

Our Olympia Chimney Chimney Repair Process
Here’s how a repair call goes at Flint Chimney Co Hempstead, from the first phone call to the final walkthrough. No surprises, no disappearing acts.
- 1
You call (516) 559-6922. A live person answers, day or night. We ask what you’re seeing, what the chimney is attached to, and when it started. We book a window that works.
- 2
We inspect the Olympia Chimney system. A background-checked, uniformed technician arrives and checks the exterior from the roof, the interior firebox, and the flue with a camera when needed. You see the photos. You don’t get told “you need a liner” without seeing the evidence.
- 3
We write the price before any work starts. The scope, the materials, the labor, the number. You approve it or you don’t. There is no version of this job where the invoice comes back higher than the number you agreed to.
- 4
We do the repair. We use Olympia Chimney OEM parts when they are the right part for the job. When a quality aftermarket part from DuraFlex or a HeatShield product does the job better for less money, we tell you and use that instead. You get the choice, not a margin decision.
- 5
We test the system. After the repair, we run a smoke test or draft check to confirm the flue is moving air properly and nothing is leaking where it should not be.
- 6
You get the 365-Day Done Right Promise in writing. Every repair carries a written guarantee valid for one full year. If a covered repair fails during that year, we come back and redo it at no charge. No argument, no invoice.

AfterWhat Olympia Chimney Chimney Repair Costs in Hempstead
Here are the ranges we quote most often for Olympia Chimney repair work in Hempstead. These are real numbers from real jobs, not a national average.
- Mortar repointing (small area): $350 to $700
- Flashing repair or reset: $400 to $900
- Chimney crown rebuild: $800 to $1,500
- Spalled brick replacement (per section): $600 to $1,200
- Partial chimney rebuild (top courses): $1,500 to $3,500
- Flue relining with DuraFlex or HeatShield: $1,800 to $4,500
What moves the price? Two things mostly. Height and access. A two-story chimney on a steep roof in Hempstead costs more to work on than a single-story straight run, because of staging and safety equipment. The second mover is the condition of what’s around the failing part. A flashing repair is quick. A flashing repair on a chimney that also needs brick replacement and crown work is a different job. Call (516) 559-6922 and we’ll give you a written estimate that includes everything.
Why Hempstead Homeowners Call Flint Chimney Co Hempstead for Olympia Chimney Work
We’ve been operating since 2002 as part of the Garrison Partners family of independently owned chimney service companies. That means we don’t answer to a franchise manual. We answer to a standard: The Garrison Standard. Written price before work. Written guarantee on the work. A live person on the phone. It’s not complicated.
Our techs know Olympia Chimney systems because they’ve repaired enough of them across Hempstead to have seen the failure patterns firsthand. When a job calls for a liner, we’ll quote DuraFlex. When a repair calls for resurfacing, we look at HeatShield. When a crown needs sealing, the Gelco product gets considered. We’re not married to one brand. We’re married to the repair that holds. That’s the thing Hank says on every tough diagnostic: “The flue tells the truth. You just have to know how to read it.”
FAQs
No, not when the repair is done correctly and documented. An independent repair does not automatically void an Olympia Chimney warranty, but using incorrectly sized or incompatible parts can. We keep documentation on every job: what we found, what we did, and what products went in. If you ever need to file a claim, you’ll have the paper trail.
Some are, especially older model components that Olympia Chimney no longer stocks. When an OEM part is unavailable, we’ll quote the closest equivalent from our trade brands – DuraFlex for liners, HeatShield for resurfacing, Gelco for sealants – and tell you why it’s a safe substitute. You’ll never get a mystery part that we “found somewhere.”
Repair is almost always the answer if the structural masonry is sound, the flue is intact, and the problem is localized: flashing, a cracked crown, a section of bad mortar, a few spalled bricks. Replacement becomes the honest recommendation when the liner is perforated, the structure is leaning, or the repair cost would exceed two-thirds of the replacement cost. We’ll show you the camera footage either way. Call (516) 559-6922 for an honest assessment.
Most non-emergency repairs are scheduled within five to ten business days, depending on weather and roof access. A live person answers the phone 24/7, so you’ll know your window before you hang up. We don’t promise same-day service, because the honest answer is that roof work in Hempstead weather has to be scheduled properly.
We come back and fix it at no charge. Every repair from Flint Chimney Co Hempstead carries our 365-Day Done Right Promise, a written guarantee valid for one full year from the service date. Covered repairs get a free return visit. No charge, no argument, no fine print about how it was “probably the weather.”
If you’ve got an Olympia Chimney system in Hempstead and something doesn’t look right, call (516) 559-6922. We’ll come out, put a camera on it if needed, and tell you what’s actually wrong. Free estimates, written pricing, and no repair you didn’t approve.
