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 Easton Owner’s Guide
Olympia Chimney crown repair in Easton typically runs $450-$850 installed, depending on whether we’re sealing hairline cracks or pouring a new concrete crown. We stock Olympia Chimney-compatible crown sealants and forms on our trucks, and most Easton jobs are completed in a single visit. Homeowners usually spot trouble after heavy rain: water pooling on the crown surface, dark streaks down the chimney face, or bits of concrete in the yard after a freeze-thaw cycle. Russell Haines and our crew have replaced dozens of these on colonials near the Delaware Canal where the crown was never built with the proper slope to shed water.
Which Olympia Chimney Models This Applies To
Olympia Chimney crowns are found across their stainless steel liner systems and masonry chimney product lines, but the crown itself is the poured concrete cap at the top of your chimney, not a metal component. The critical match is crown dimensions: inside lip height, overhang beyond the flue tile, and slope angle. Most Easton homes built between 1960 and 1995 have crowns measuring 24 to 36 inches square with a 2-inch minimum overhang. We verify this with a camera inspection before quoting.
The OEM approach from Olympia Chimney specifies a 4,000 PSI concrete mix with integral waterproofing. We use that spec, or a compatible professional-grade pour from Copperfield when the original form is salvageable. The gotcha: some Olympia Chimney systems have a chase cover that sits below the crown, and if that cover has rusted through, replacing the crown alone traps moisture. We check both. Hearthstone Chimney Co. is an independent service provider, not affiliated with Olympia Chimney.
Signs Your Olympia Chimney Crown Repair Is Failing
- Hairline cracks spreading across the surface. These start small after the first few Easton winters, then widen as water freezes and expands. Once cracks reach 1/8 inch, water reaches the brick below and the damage accelerates.
- Concrete chunks or sand collecting at the chimney base. This means the crown surface is spalling, usually from a mix that lacked air entrainment for freeze-thaw cycles. PA’s 20 to 30 annual freeze-thaw events chew up weak concrete fast.
- Water stains on the ceiling near the chimney breast. A cracked crown lets water run down the flue liner or between the liner and brick. By the time you see interior stains, the crown has been leaking for one or two seasons.
- The crown sits flat or bowls inward. Proper crowns slope at least 3/8 inch per foot to shed water. Flat crowns pool water, and in Easton’s spring rains, that standing water finds every crack.
- Gaps between the crown edge and the brick chimney. This separation means the crown is separating from the structure, often from rusted crown anchor bolts or inadequate bond when originally poured. Left alone, the crown can shift and crack the flue tile below.
Replacement Cost & What’s Included
| Repair Type | Typical Range in Easton | What’s Included |
|---|---|---|
| Crown sealing (hairline cracks) | $450-$650 | Surface prep, flexible crown coat application, 5-year material warranty |
| Partial crown rebuild (spalling, minor separation) | $650-$850 | Form and pour new crown section, integrate with existing, camera inspection |
| Full crown replacement with chase cover inspection | $850-$1,400 | Remove old crown, inspect flue tile and chase cover, form and pour new 4,000 PSI crown with proper slope |
What drives the range: crown size, accessibility (steep roof pitch adds time), and whether the flue tile or chase cover needs attention at the same time. We price upfront after inspection, not after we’re on the roof. The number on the estimate is the number on the invoice. Every crown repair carries our 90-Day Done Right Promise in writing, no arguing.
DIY or Call Us?
You can safely check your crown from the ground with binoculars: look for cracks, missing chunks, or standing water after rain. You can also run a hose on the roof near the chimney (not directly on the crown) and check for new interior leaks.
What you should not do: climb onto the roof to patch the crown yourself. The concrete work requires forms, proper slope, and a cure time that won’t wash out in the next rain. More importantly, chimney crowns sit at height, on a surface that may already be structurally compromised. We’ve seen homeowners step through a rotted chase cover they didn’t know was there. The repair itself isn’t high-tension dangerous, but the access is. Call us at (610) 756-1504. We’ll photograph what we find, explain it plain English, and let you decide.
FAQs
A properly poured concrete crown with integral waterproofing lasts 20 to 30 years in the Lehigh Valley. The ones we replace most often in Easton were poured without slope or with a weak mix, and they fail in 8 to 12 years. Call (610) 756-1504 for a free inspection and we’ll tell you where yours stands.
Yes, if the cracks are hairline, the crown still has proper slope, and there’s no separation from the brick. We apply a flexible crown coat that bridges small cracks and adds waterproofing. If the crown is flat, spalled, or separated, replacement is the only lasting fix. We show you the camera photos and recommend accordingly.
Most crown repairs or replacements are completed in a single visit of 3 to 5 hours. Full replacements require a return trip to remove forms after the concrete cures, but we handle that scheduling. You don’t need to be home for the form removal.
We carry professional-grade crown sealants, forming materials, and 4,000 PSI concrete mix compatible with Olympia Chimney specifications. For full replacements, we fabricate forms to your chimney’s exact dimensions on site. Most Easton jobs don’t require a second trip for materials.
