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.

How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney stainless single-flue caps - weld-seam corrosion at the skirt. The 304-grade stainless models sold through many Milford-area suppliers in the 2010s develop pinhole leaks where the skirt meets the mesh screen, especially on north-facing exposures above the Delaware River valley where fog sits heavy. We spot this with a camera inspection, then fit a replacement cap with a heavier-gauge skirt or switch to a Gelco cap with a rolled edge if the flue configuration allows.
- Olympia Chimney multi-flue enclosures - lid sag and water pooling. The bolted-lid design on older Olympia multi-flue units (pre-2018) lets the lid settle after a decade of Pike County freeze-thaw cycles. Water ponds, freezes, and cracks the crown beneath. We measure the sag, replace the lid with a reinforced Olympia-compatible unit or a custom-fabricated alternative, and reseal the crown with HeatShield CrownCoat.
- Olympia Chimney galvanized economy caps - rust-through at the base ring. These were common on spec homes built during Milford’s 2005-2012 building boom. The galvanized coating fails first at the base ring where creosote condensation collects. We do not reinstall galvanized; we upgrade to stainless or copper and document the flue condition because rust staining often signals deeper crown damage.
- Olympia Chimney wind-directional caps - seized pivot joints. The rotating collar on Olympia’s wind-directional line gums up with creosote and river-valley pollen, freezing the cap in one position and creating a downdraft path. We disassemble, clean the pivot, and if the bushing is worn, source a compatible replacement or recommend a fixed-direction Gelco cap for flues that draw adequately without rotation.
- Olympia Chimney crown-mounted caps - anchor bolt pullout from deteriorated concrete. When an Olympia cap is bolted to a crown that has already begun spalling, the torque of seasonal expansion pops the anchors. We remove the cap, assess whether the crown can be resurfaced with HeatShield or needs rebuild, then reinstall with epoxy-set anchors that bite into sound substrate.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, notes your Olympia Chimney model if you know it, and books a window. We do not give a repair quote over the phone; we need eyes on the system.
- 2
Level-2 camera inspection. Our technician photographs the cap, crown, and flue interior from the roof and from inside the firebox. You see the images on a tablet before we discuss anything.
- 3
Parts decision. If your Olympia Chimney cap is still in production, we quote OEM. If it is discontinued or the OEM lead time exceeds two weeks, we propose a quality aftermarket equivalent from Gelco or Famco and explain the trade-off. No parts change happens without your approval.
- 4
The repair. For cap replacement, we remove the old unit, inspect the flue tile and crown edge, install the new cap with proper clearances, and seal anchor points. For crown work, we grind loose material, apply bonding agent, and trowel HeatShield CrownCoat or pour new concrete depending on depth of damage.
- 5
Post-repair verification. We run the camera again to confirm no debris fell into the flue, check cap draw with a smoke pencil, and photograph the finished work.
- 6
Written guarantee and cleanup. You receive a printed report with photos, our 90-Day Done Right Promise, and an invoice that matches the upfront number. We haul away the old cap.

Why Milford Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We are an independent Olympia Chimney service provider - not affiliated with the manufacturer, which means we work for you, not a warranty desk. Our techs carry Olympia-compatible inventory alongside DuraFlex, HeatShield, Gelco, and Famco parts, so we are not waiting on a warehouse in Ohio while your flue takes on water.
The 90-Day Done Right Promise governs every job: if it is not right, we come back, in writing, no arguing. That is the Keystone Standard. Russell Haines and his crew have been on roofs in Milford since the 1980s - from the riverfront cottages to the hillside homes off Route 6 - and we plan to be here when the next generation needs us. Photos you can see. A plain-English verdict. A square deal on the bill.
FAQs
No - manufacturer warranties on chimney caps cover defects in materials and workmanship, not who installed them. As an independent Olympia Chimney service provider, we document our work with photos and receipts so any legitimate warranty claim remains valid. If you have a current warranty issue, we will help you identify whether it is a manufacturing defect or wear-and-tear. Call (610) 991-8179 and we will sort it out.
Many Olympia Chimney cap lines from the 2000s and 2010s are discontinued, but we stock cross-reference fittings and work with regional suppliers to source compatible hardware. When OEM is unavailable, we recommend quality aftermarket caps from Gelco or Famco that match or exceed the original specifications. We never leave a flue open while waiting on back-ordered parts.
If the screen is intact, the lid sits square, and only the mounting hardware is loose, repair is usually possible. If the mesh is rusted through, the lid sags, or the base ring shows corrosion holes, replacement is the sound choice. We show you the camera images and explain which category your cap falls into. Estimates are free - call (610) 991-8179.
Most single-flue replacements take 45 to 90 minutes on site; multi-flue enclosures or jobs requiring crown repair run two to four hours. We complete most jobs in one visit because our trucks carry the common Olympia-compatible sizes. You do not need to be home for the exterior work, though we prefer someone available to review the photos and approve the scope.
A cracked crown lets water into the chimney structure, where freeze-thaw cycles in Milford’s hard winters open the cracks wider and accelerate brick and liner damage. The repair does not get cheaper with time. That said, not every crack demands immediate action - a hairline surface crack may be coatable, while a separated crown with exposed flue tile needs prompt work. Our camera inspection tells you which situation you are in, and we will say plainly if something can wait a season. Call (610) 991-8179 for a free look.
Find out what is wrong, say so plainly, fix it right, and stand behind it. That is how we have worked since 1984, and it is how we will handle your Olympia Chimney cap or crown in Milford. Call (610) 991-8179 - a live person answers, every day, every hour - or ask us out for a free estimate. We will be there when we say.
