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 Crown Repair: The Lawrence Owner’s Guide
If the concrete or masonry crown on top of your Olympia Chimney is cracked, spalling, or letting water run down the flue, we can replace it. Most Olympia Chimney crown repairs in Lawrence run between $450 and $900 installed, depending on how much of the old crown needs to come off and whether the flue tiles are still sound. We stock Olympia Chimney-compatible crown materials on the truck, which means the job is usually done in one visit. Most homeowners notice the problem first as a water stain near the ceiling, a musty smell in the firebox, or crumbling bits of concrete showing up on the roof after a storm.

Here’s what you need to know about getting it fixed right in Lawrence, without paying for work that does not need doing.
Which Olympia Chimney Models This Applies To
Olympia Chimney sells crown repair systems that fit their standard masonry chimney flue liners, and the crown itself is the concrete sloped cap that sits on top of the chimney chase or masonry stack. The key compatibility point is the flue tile size, not the fireplace model below it. If your home has an 8″ by 8″ or 8″ by 12″ clay flue tile, that is the standard footprint most Olympia Chimney crowns are built around. We measure the outside dimensions of the flue and the top course of brick before ordering or cutting anything, because a crown that overhangs the brick by less than two inches will not shed water properly.
On older Lawrence homes in the Five Towns area, we still see original clay flue liners that have been in place since the house was built. Olympia Chimney’s crown products are designed to work with those original tiles, but if the top of the flue is chipped or spalled, the crown will not seat tight. In those cases, the flue tile gets refaced first. We do not sell Olympia-branded OEM crowns directly, since Top Hat Chimney is an independent service company and not affiliated with Olympia Chimney. What we install is an Olympia-compatible crown built from the same spec, matched to the flue dimensions. We also work with DuraFlex, HeatShield, and Gelco products when a crown repair is paired with a liner job.
Signs Your Olympia Chimney Crown Repair Is Failing
A failing crown does not always announce itself. Most of the time in Lawrence, the signs show up quietly over one or two heavy rain seasons.
- Water stains on the ceiling near the chimney chase. The crown cracks, water seeps into the masonry, and gravity carries it down to whichever ceiling is in the way. The stain is almost never directly under the chimney, which is why it takes people a while to connect the two.
- Crumbled chunks of concrete on the roof or in the gutter. Freeze-thaw cycles on Long Island are hard on a crown. Water gets into a hairline crack, freezes, expands, and pops a piece off. Once you can see missing concrete, the crack has been working for at least a season.
- Musty smell inside the firebox, especially after rain. That is damp masonry, and a cracked crown is the most common entry point. It is not a smell that clears up on its own.
- Efflorescence, which is the white chalky stain on the brick below the crown. That white powder is salt being drawn out of the brick by moving water. It tells you water has been getting in long enough to move minerals around inside the masonry.
- Flue tile pieces in the firebox. When the crown fails badly, the flue tiles below it start to take on water and can spall. If you find thin clay shards in the firebox, the problem has traveled past the crown.
Replacement Cost & What’s Included
In Lawrence, a full Olympia Chimney crown replacement mostly lands between $450 and $900. The spread depends on a few things: how much of the old crown has to be removed, whether the flue tiles need refacing, and whether your roof is steep enough that we need extra staging to work safely. Smaller chase-top crowns that sit on a fabricated chimney run toward the lower end. A large masonry crown that requires building a new wood form and pouring fresh concrete runs higher.
The price you get on the phone is the price on the invoice. That is not a sales line, that is how we have worked since 1999. Every crown job includes removal of the failed material, cleaning the top course, refacing any chipped flue tile if needed, forming and pouring the new crown with a proper drip edge, and cleanup. The work is covered by our 90-Day Done Right Promise in writing. If something is not right, call us and we come back at no charge. And remember, we offer $40 off any repair over $200, plus 10% off for seniors and veterans, always.
DIY or Call Us?
You can safely check for visible cracks from the ground with a pair of binoculars, and you can check the attic ceiling for water stains. That is about as far as it should go. A crown replacement means working at the top of a chimney, often on a roof pitched enough that the footing is compromised. In Lawrence’s older housing stock, that can mean a 9/12 roofline or worse on the taller colonials near the Five Towns area. Mixing and forming a crown that sheds water properly takes a real understanding of slope, overhang, and expansion joints. We have also pulled more than one homeowner off a ladder who tried to patch a crown with roofing tar, which fails within a year because it cannot handle thermal movement.
If you want to check yours from the ground and call us with what you see, that is a good conversation. Wendell Pike has been on enough Lawrence roofs to know which chimneys have a crown worth saving and which need full replacement. He will tell you straight. If it’s clean, he’ll tell you it’s clean. Call (516) 604-2573 and we will walk through what you are seeing.
FAQs
A properly poured crown on a Long Island chimney should last 15 to 25 years. The ones that fail early, meaning inside 5 to 8 years, are usually the ones that were too thin, had no drip edge, or were patched instead of replaced. Once we replace a crown in Lawrence, we do not expect to see it again for a couple of decades. If yours needs a second look sooner, call (516) 604-2573 and we will explain what we found the first time.
Sometimes, if the crack is hairline and the concrete is still solid underneath. We use a sealant that flexes with the thermal movement, and it works well for small surface cracks. If the concrete is spalling or a chunk is missing, a patch will fail because there is no way to bond the new material to the old without the joint opening up again. The honest answer is: minor cracks can often be sealed, missing concrete cannot. We will show you camera footage either way and let you decide what the repair scope needs to be. Call (516) 604-2573 for an assessment.
Most Olympia Chimney crown replacements in Lawrence are done in a single day. We get there in the morning, remove the old crown, prep the top, pour the new one, and clean up before dinner. If the flue tile needs refacing, that can add a few hours, but it is still typically a one-visit job. Weather is the usual reason for a delay, since concrete needs dry conditions to cure properly. Call (516) 604-2573 to schedule around the weather, not against it.
Yes. We carry Olympia-compatible crown forms, sealants, and flue-tile patching materials on the truck for standard flue sizes. If your chimney has an unusual flue footprint, we will source the right material before we get on the roof, not after. You will know the plan and the price before a single tool comes off the truck. No surprises at the door, and a live person answers the phone around the clock if you want to talk it through first.
If your Olympia Chimney crown is showing signs of trouble, don’t wait for the next freeze-thaw cycle to do more damage. Call Top Hat Chimney at (516) 604-2573 for a free estimate.
