We’ve been driving to Redmond since 1984, long before the Microsoft campus transformed the downtown corridor. Our trucks know the difference between the tight driveways on Education Hill’s 1970s ramblers and the newer planned communities off Redmond Ridge in 98053. That familiarity matters when we’re hauling concrete crown forms and stainless cap inventory up narrow hillside streets or coordinating access with Redmond’s hillside homeowners’ associations. Russell Haines built this company on the principle that knowing the territory is as important as knowing the trade.

Why Hearthstone Chimney Co. Is Redmond’s Preferred Chimney Cap & Crown Company

Local reputation built on documented work. Redmond homeowners have called us back for decades because we photograph every crown crack, every corroded cap flange, and every mortar joint before we touch a tool. You see what we see. The verdict comes in plain English, not contractor jargon, and the 90-Day Done Right Promise covers every cap and crown job in writing with no arguing.

Response time that respects your schedule. From our dispatch, we’re typically on Education Hill or in the Grass Lawn neighborhood within 45 minutes to an hour. Redmond Ridge and Novelty Hill take a bit longer with the hill climb, but we book those appointments with buffer time built in. We’ll be there when we say.

We understand Redmond’s wet valley microclimate. The Sammamish River valley traps moisture against chimney masonry in ways that Seattle’s more exposed neighborhoods don’t experience. Annual precipitation here runs higher than downtown, and that sustained dampness accelerates crown cracking and cap seal failure. Our Chimney Cap & Crown technicians don’t just install parts; we specify materials and flashing details for this specific environment.

A live person answers the phone. Every hour, every day. Not a callback queue, not an app. When water is dripping down your flue during a January Pineapple Express storm, you reach a human who can dispatch help to 98052, 98053, or 98073 immediately.

Our Chimney Cap & Crown Services in Redmond

Chimney Cap Installation

New cap installation in Redmond runs $340-$620 for standard single-flue stainless or galvanized models, with multi-flue and custom caps ranging higher. We size caps to the flue, not the chimney top, because an oversized cap on a Redmond chimney traps moisture against the crown instead of shedding it. On Education Hill’s original 1970s fireplaces, we frequently find unlined flues that require specific cap and screening combinations to meet current code. Our technicians carry Gelco and Olympia Chimney inventory on the truck for same-day installation.

Cap Replacement

Cap replacement in Redmond costs $280-$540 when the existing flue is sound and we’re swapping a corroded or improperly fitted unit. The damp valley air here rusts through cheap builder-grade caps in seven to ten years; we see this constantly in Grass Lawn and the Overlake corridor where original 1980s caps have finally failed. We remove the old cap, inspect the flue tile for hidden cracks, and install a proper replacement with correct overhang and mesh screening. Done right, and we stand behind it.

Crown Repair

Crown repair in Redmond typically costs $380-$720 for crack sealing, resurfacing, and flashing integration on masonry chimneys with salvageable concrete crowns. The 1970s tract homes on Education Hill suffer crown deterioration at higher rates than newer construction because decades of orographic moisture from the Cascade foothills have saturated the soft brick and porous crown concrete. We use professional-grade crown sealants formulated for wet climates, not the box-store acrylics that peel within two seasons. A square deal: no surprises on the bill.

Crown Coating & Rebuild

When a Redmond crown has cracked through to the rebar or separated from the brick course, we pour a new cast-in-place crown at $680-$1,240. This includes forming, pouring high-strength concrete with proper slope and drip edge, and integrating new counter-flashing. On chimneys where the crown was never properly constructed, we rebuild from the brick up. The freeze-thaw cycles in Redmond’s hillside neighborhoods, even mild ones, spall soft 1970s brick and destroy poorly formed crowns. We document the before condition with photos you can see, explain the plain-English verdict, and execute the repair so you don’t think about it again.

Trusted Brands We Service in Redmond

We stock and install professional-grade caps and crown materials from HeatShield, Gelco, Olympia Chimney, and Famco, brands that hold up to Redmond’s persistent dampness without the corrosion and seal failures we see on generic hardware-store inventory. Our trucks carry the common sizes for 98052’s masonry flues and the adapter configurations for 98053’s factory-built units, which means most Redmond cap and crown jobs finish in one visit. When a custom fabrication is needed for an unusual flue configuration on an older Education Hill home, we order from the same suppliers we’ve used for over 42 years, with turnaround measured in days, not weeks. No builder-grade substitutes, no excuses.

Common Chimney Cap & Crown Problems We See in Redmond Homes

• Crown cracks from sustained valley moisture. Redmond’s position below the Sammamish Plateau creates a foggy, wet microclimate where concrete crowns absorb moisture for months. That saturation expands freeze-thaw damage even in light frost, and by February we’re repairing crowns that cracked through in December.
• Moss and organic growth accelerating mortar decay. The orographic moisture that stalls against Redmond’s hillsides feeds moss colonization on chimney brick and crown surfaces. That growth holds water against mortar joints, eroding the bond between crown and brick course until the crown separates entirely.
• Improperly converted gas log sets with missing caps. On Education Hill, we regularly encounter 1990s gas conversions where previous owners removed the original cap and never installed proper venting hardware. An oversize masonry flue with an unsealed top is an open path for rain and vermin, and the draft mismatch creates a carbon-monoxide risk that a correct cap and liner combination solves.
• Flashing failure at the roofline masking as crown leaks. Redmond’s heavy annual rainfall, approaching 50 inches, tests every chimney penetration. Water that appears to come from the crown often originates at corroded step flashing or a missing cricket on the uphill side. Our Level-2 camera inspections distinguish true crown failure from flashing problems before we quote unnecessary work.
