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 Waldorf: What to Know First
We handle Olympia Chimney cap and crown work across Waldorf and Charles County, and most jobs are done in a single visit. A straightforward cap replacement on an Olympia unit typically runs $340-$680 installed, while crown repair or coating lands between $450 and $900 depending on how much of the original crown is still sound. This page is for Waldorf homeowners with an Olympia Chimney product who want straight answers on caps and crowns, what fails, what it costs, and whether the work can wait. Call (240) 358-4452 and Wendell Pike or one of his crew will walk you through what you’re seeing.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney builds solid stainless and galvanized systems, but the cap and crown take the worst of what Waldorf weather throws at them. Hot summers, freeze-thaw cycles in February, and the damp air off the Potomac all work on exposed metal and masonry. Here’s what we find on Olympia jobs in Waldorf, week in and week out:
- Olympia stainless caps losing their mesh to creosote buildup. The mesh on Olympia’s standard caps is fine enough to stop sparks, but fine mesh loads up with creosote faster on wood-burning flues. Once it clogs, draft drops and smoke backs into the house. The fix is usually a cap replacement with a mesh pattern better suited to the burn habits of the household, not just another stock Olympia cap that will clog the same way in eighteen months.
- Galvanized caps rusting at the base ring. We see older Olympia galvanized caps rust out where the cap skirt meets the flue tile. It starts as cosmetic surface rust and within two or three seasons it becomes pinholes that let rain straight down the flue. On a Waldorf roof with afternoon sun exposure, the heating and cooling cycles accelerate it. We replace with stainless when the flue is still in good shape, and we don’t sell a galvanized cap to replace a galvanized cap that failed.
- Crown spalling on masonry chimneys with Olympia liners. The crown is the concrete or mortar slab on top of the chimney, and it fails independent of the brand of liner inside. But when an Olympia liner was installed and the crown was left alone, the crown keeps cracking and the water runs down alongside the liner. In Waldorf, freeze-thaw is the culprit. Water gets into hairline cracks, freezes, expands, and pops the surface off. We repair or recoat the crown with a breathable crown seal so water stays out and the liner stays dry.
- Multi-flue Olympia caps with wind-driven rain bypass. When a Waldorf home has two flues sharing one chase, an Olympia multi-flue cap has to cover both terminations cleanly. If the cap was sized to the chase and not to the flue layout, the outer flue catches rain from the prevailing west wind. Homeowners call us about water in the firebox after storms, and the real cause is the cap silhouette, not the liner. We size the replacement to the actual flue spread, not the outer brick dimension.
- Improper aftermarket caps on Olympia liners. Plenty of Olympia liners in Charles County got a bargain aftermarket cap at some point, and the mounting doesn’t match the liner diameter. That gap lets rain in and birds build in the annular space. We see starlings and squirrels in there most springs. The right fix is a cap matched to the Olympia liner OD, with a mounting band that actually seats on the liner, not floating on the tile.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
You call, we talk like people. A live person answers at (240) 358-4452, and it may well be Wendell. We ask what you’re seeing, when it started, and what kind of chimney setup you have. No script, no pressure.
- 2
We get on the roof and look. Wendell or one of his crew inspects the Olympia cap, the crown, the flue tile, and the top few feet of the liner. We take photos and, if water or draft is the complaint, we run a camera down the flue so you can see what we see.
- 3
We give you a plain-English verdict. If the cap is serviceable and the crown just needs sealing, that’s what we’ll tell you. If the cap is rusted through or the crown is spalled beyond repair, we show you the footage and explain the two ways forward. The number we quote on the phone holds, because we set it after we know what the job actually is.
- 4
We do the work with the right parts. For Olympia systems we use OEM when the lining and termination are still matching, and quality aftermarket when an upgrade is the honest call. You’ll know which one and why before we start, and the price is set before a tool comes off the truck.
- 5
We test and clean up. We check cap seating, water-tightness of the crown seal, and draft if that was part of the complaint. Then we sweep the area and make sure the roof looks better than we found it.
- 6
You get it in writing. Every Olympia cap and crown job carries the 90-Day Done Right Promise. If something isn’t right, one call brings us back at no charge.
What Olympia Chimney Chimney Cap & Crown Costs in Waldorf
Straight numbers, the way Wendell quotes them. A standard Olympia stainless cap replacement runs $340-$680 installed, depending on flue diameter and access. A custom or multi-flue cap for an Olympia setup can reach $700-$950 when the chase is wide or the flue layout needs a one-off size. Crown sealing or coating on a typical Waldorf masonry chimney runs $450-$900, and a full crown rebuild with forming and proper overhang is $900-$1,400. What moves the price: roof pitch and access, flue count, liner condition, and whether we’re matching an existing Olympia part or correcting a previous wrong-size installation. Estimates are free, and if you already have a written estimate, bring it in and Wendell will give you a second opinion at no charge. Call (240) 358-4452 and get the exact number for your chimney.
Why Waldorf Homeowners Call Top Hat Chimney for Olympia Chimney Work
We’ve been working on chimneys in Waldorf and Charles County since 1999, and Olympia Chimney products have shown up here for years, mostly in the St. Charles, Westlake, and White Plains neighborhoods. Wendell Pike runs the company and still climbs the roofs himself. He grew up in San Diego, learned the trade fundamentals at Palomar College, and has spent the decades since working through every chimney configuration you can imagine. When we work on an Olympia cap or crown, we also know what’s downstream: the liner, the appliance, the draft. And because we service DuraFlex, HeatShield, and Gelco systems too, we can tell you honestly whether the Olympia component is the problem or whether something else in the system needs attention. Our techs are background-checked, uniformed, and show up when they say they will. If the job doesn’t need doing, we’ll tell you that too.
FAQs
Replacing a cap on an Olympia Chimney system does not void the liner or system warranty, provided the replacement cap is installed to the manufacturer’s diameter and clearance specifications and the termination remains code-compliant. As an independent Olympia Chimney service provider, we install caps that match or exceed the original spec, and we document the installation so your warranty position stays clean.
Most Olympia caps we see in Waldorf need replacing rather than repairing, because the failure is rust-through or clogged mesh that can’t be economically restored. If the cap is structurally sound but the mesh is partially loaded, we can sometimes clean and re-seat it, which runs $150-$250. If you’re not sure, we’ll tell you straight before you spend a dime. Call (240) 358-4452 for a free estimate.
For most Olympia cap replacements in Waldorf, we can be on the roof within a few days of your call, and the job itself is done in a single visit, usually two to three hours. Crown work takes longer because the sealant needs to cure, and we schedule that around weather so the repair actually sets. We book by the day, not by the hour, and we call if anything shifts.
The quick test is water intrusion. If rain comes down the flue and into the firebox, the cap is the prime suspect. If the chimney smells damp or you see white efflorescence on the brick below the crown, the crown is cracked and letting water into the masonry. In Waldorf, the two often fail together because the same freeze-thaw cycles attack both. We camera the flue and photograph the crown so you can see exactly what’s failing before we quote anything.
Yes. We service and install DuraFlex, HeatShield, and Gelco liners, and we regularly work on chimneys where an Olympia cap or crown sits on top of another brand’s liner. That’s the reality of older Waldorf homes: the chimney is a mix of components installed by different contractors over the years, and we treat it as one system that has to work together.
