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 White Plains Owner’s Guide
Olympia Chimney crown repair in White Plains typically runs $425-$1,100 installed, depending on whether we’re sealing surface cracks or rebuilding the crown entirely. We stock Olympia Chimney crown-coat materials and matching caps on our trucks, so most White Plains jobs are done in a single visit. Homeowners usually discover the crown has failed when they spot water stains on the ceiling near the fireplace, or when a mason points out spalling during an unrelated chimney inspection.
The crown is the concrete or mortar slab that caps the top of the chimney, and its only job is to shed water away from the flue and masonry. When it cracks, water gets behind it, works its way into the brick, and freezes come January. That freeze-thaw cycle is what turns a $600 crown repair into a $4,000 rebuild. In White Plains, where winter temperatures swing above and below freezing dozens of times each season, a compromised crown doesn’t stay a small problem for long.

Which Olympia Chimney Models This Applies To
Olympia Chimney makes two product families that show up in White Plains homes: their stainless steel chimney liner systems and their factory-built chimney caps and crowns. If your crown is a cast-in-place concrete slab poured over brick or block, we’re repairing that surface with Olympia CrownCoat, a flexible elastomeric sealant Olympia specifically formulates for freeze-thaw climates. If you have a factory-built Olympia chimney with a metal chase top, the “crown” is actually a galvanized or stainless chase pan, and we’re matching that against Olympia’s current ChaseTop line, which uses 24-gauge stainless and a hemmed edge that resists oil-canning.
The compatibility question that trips up a lot of owners: Olympia’s older TD-series caps use a different mounting collar than their current CrownShield line, and the two are not interchangeable without an adapter. If your cap is rusted through but the crown underneath is sound, we can often swap just the cap. If the crown is compromised, we fix the crown first. The camera tells us which situation you’re in, and Corrine Halstead has seen enough older colonials near the Gedney and Highlands neighborhoods to know that a cap that looks fine from the ground is often hiding a crown that’s been quietly failing for five years. We identify your part by measuring the flue opening, checking the mounting collar, and matching it against Olympia’s current spec sheets, then we show you the photos.
One note on sourcing: Level Two Chimney White Plains is an independent service provider. We’re not affiliated with Olympia Chimney, but we buy their materials through Haven’s purchasing network specifically so the price stays honest. We also stock compatible materials from DuraFlex, HeatShield, and Gelco when a repair calls for a different product.
Signs Your Olympia Chimney Crown Repair Is Failing

- Water stains on the ceiling or wall near the fireplace. This is the one that gets our phone to ring. Water entering through a cracked crown travels down the flue or through the masonry and shows up inside the house, often months after the crack formed.
- Spalling brick or flaking mortar near the top of the chimney. Spalling is when the face of the brick pops off in sheets. It happens because water soaks in, freezes, and expands. The crown failed first; the brick damage is the evidence.
- A rusted or loose chimney cap. If the cap is rusted through or no longer sits flush, water is getting directly onto the crown and into the flue. This is the cheapest stage to catch the problem, and we’d rather find it here than after a winter of freeze-thaw.
- Efflorescence, the white chalky powder, on the chimney exterior. That white film is mineral salt left behind when water evaporates out of the masonry. It means water is inside the brick, and on an Olympia-capped chimney, the crown is the first place we look.
- Pieces of mortar or concrete in the gutter or on the roof near the chimney. If the crown is spalling, chunks end up in the gutter. You might not see the crown from the ground, but the gutter will tell you something is degrading up there.

AfterReplacement Cost & What’s Included
Crown repair in White Plains breaks down by the extent of the damage, and we quote the job in writing before anyone picks up a trowel. Here’s the honest range:
- Crown sealing and minor crack repair: $425-$625. We grind hairline cracks clean, apply Olympia CrownCoat or an equivalent elastomeric, and re-seal the cap mounting points. This buys years when the crown is otherwise structurally sound.
- Crown resurfacing with partial rebuild: $650-$850. Applies when the crown is spalling in sections but still has enough of the original slab to hold a new surface. We build a wire-lath form, apply new mortar and crown coat, and slope it for drainage.
- Full crown rebuild with new cap: $900-$1,100. We remove the failed crown, pour or form a properly sloped replacement, and install a new Olympia-compatible cap. This is the repair that ends the cycle for good.
Every price includes the camera inspection, the written scope, labor, materials, and the documented photo record before and after. The written warranty is specific to the repair; we don’t hand you a vague “guaranteed” handshake, we put it in writing. If you have a written estimate from another White Plains chimney company, bring it in; we’ll give you a free second opinion on it.
DIY or Call Us?

A crown repair on a single-story chimney with a shallow pitch roof and easy access is a job some homeowners take on. The honest version: sealing hairline cracks is within reach if you can safely get to the crown and the damage is minor. But that’s a big “if.” Most White Plains chimneys are on roofs with a pitch that makes a homeowner’s life harder than it needs to be, and you’re working at height with a bucket of mortar, which is how crowns end up with improper slope, which is how they fail again in two years. When the crown is spalling or the cap needs replacement, a bad do-it-yourself attempt means a mulligan that costs more than the first repair would have.
We’ll also say this plainly: if your crown has failed to the point that water is inside the flue, you’re not just repairing a slab of concrete. Water mixing with creosote is corrosive to a liner, and a compromised liner is a carbon monoxide risk. The camera does not guess. Neither do we. Call (914) 350-5204, and we’ll tell you what the camera found and what it costs before you decide anything.
FAQs
A properly sloped, properly sealed crown repair in White Plains weather typically lasts 10 to 15 years. The freeze-thaw cycles here are the limiting factor; a crown in a mild climate might go 20 years, but our winters shorten that lifespan, which is why we use elastomeric crown coat rather than a hard, brittle sealer.
If the crown is intact with only hairline cracks, it can usually be sealed and resurfaced. If chunks are missing, if the slab spalls when tapped, or if the slope is wrong, a rebuild is the repair that holds.
Most crown repairs and rebuilds in White Plains are done in a single visit, four to six hours on site. The materials need cure time, but the work itself doesn’t require us to come back except for larger rebuilds with multiple layers.
We stock Olympia CrownCoat, compatible cap adhesives, and common cap sizes on the truck. If your chimney needs a specific cap size we don’t carry, we order it from Olympia’s distribution network and it typically arrives in three to five business days, and you’re never charged until it’s in hand and the written price is set.
