We answer calls live at (844) 803-1545, day or night, and our technicians carry the materials to handle both the clay-tile masonry chimneys common in 97123’s older neighborhoods and the prefabricated metal systems dominating 97124’s Intel-era subdivisions.

Call (844) 803-1545

We’ve been driving out to Hillsboro since well before the Ronler Acres campus expansion turned cornfields into cul-de-sacs. That longevity matters here in a way it doesn’t in newer markets. Hillsboro’s housing stock split, between mid-century brick ranchers near downtown and the thousands of tract homes built during the semiconductor boom, means a technician who treats every chimney the same way will miss something. We don’t. Our Chimney Cap & Crown crews know the difference between a Gelco cap sized for a traditional flue and the specialized hardware a zero-clearance fireplace requires, and we stock both.

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

Hillsboro homeowners call us back. Not because we’re the cheapest, but because we document what we find, explain it in plain English, and fix it without needing a return trip. Our 90-Day Done Right Promise covers every cap and crown job in writing, no arguing, no paperwork chase. If the seal fails or the mortar doesn’t hold, we come back.

We’ve served communities across this region for over 42 years, and Hillsboro has been part of that route since the 1980s when downtown was still orchard country and the Maxwell Road corridor was two lanes. That history means something to homeowners who’ve watched three chimney companies open and close in the time we’ve been answering the same phone number.

A live person picks up every call, 24 hours a day. Not a callback queue, not an app, not “leave a message and we’ll get back to you.” When water is dripping through your crown onto the firebox at 9 PM on a Saturday, you reach someone who can dispatch a technician and give you a real arrival window.

Our background-checked, uniformed technicians carry Level-2 camera equipment and show you the photos. You’ll see the crack pattern in your crown, the rust scoring on your prefab flue cap, the mortar joint that has washed out. Then you get a plain-English verdict and upfront pricing. The number on the estimate is the number on the invoice.

Our Chimney Cap & Crown Services in Hillsboro

Cap Installation

New cap installation in Hillsboro runs $340-$620 for standard single-flue models, with multi-flue and custom configurations reaching $780-$1,150. The Tualatin Valley’s persistent winter fog, heavier here than in elevated Portland neighborhoods, drives moisture into uncapped flues at an accelerated rate. We’ve replaced firebox floor panels in Orenco Station homes where years of unimpeded rainfall degraded the system from the top down. A properly fitted cap, sized to your flue type and installed with correct clearance, stops that process cold.

Cap Replacement

Cap replacement is our most common service call in 97124. The builder-grade caps installed during the Intel housing boom were often galvanized steel at minimum specification, and twenty years of valley-floor moisture has rusted through the mesh and collar on hundreds of north Hillsboro homes. We remove the failed unit, inspect the flue tile or metal flue for collateral damage, and install a replacement in stainless steel or copper from Olympia Chimney or Famco, depending on your system and budget. Most replacements finish in under two hours.

Crown Repair

Crown repair in Hillsboro’s older 97123 neighborhoods addresses a different failure mode than what we see in the prefab-dominated north. Traditional mortar crowns on mid-century homes crack from thermal cycling and from the freeze-thaw expansion of water that has already penetrated the matrix. We chase the cracks, apply flexible crown sealant or pour a new concrete crown with proper overhang and drip edge, depending on deterioration depth. For crowns with minor cracking but sound structure, we apply HeatShield crown coating, which bridges hairlines and restores waterproofing without full replacement.

Crown Coating

Crown coating is the preventive play that too many Hillsboro homeowners skip until water stains appear on the ceiling. At $280-$450, it’s roughly one-third the cost of crown replacement and can add a decade of service life to a sound but weathered crown. We recommend it particularly for homes near Jackson Bottom Wetlands and other low-lying 97123 areas where ground-hugging moisture lingers longest. The coating we use is formulated for Pacific Northwest temperature swings, not the generic hardware-store version that cures too rigid and cracks by February.

Trusted Brands We Service in Hillsboro

We don’t substitute. Every cap, crown coating, and repair component we install comes from professional-grade manufacturers we’ve vetted over decades: HeatShield for crown restoration and resurfacing, Gelco for cap and spark arrestor assemblies, Olympia Chimney for stainless steel and copper cap systems, and Famco for specialized dampers and accessories. These aren’t brands you find at the big-box store in Cornelius, and they’re not interchangeable with builder-grade alternatives. We stock common sizes and configurations at our warehouse, which means Hillsboro customers aren’t waiting two weeks for a special-order cap while water continues entering the flue. When your technician arrives, the right part is on the truck.

Common Chimney Cap & Crown Problems We See in Hillsboro Homes

• Crown cracking accelerated by valley-floor moisture. Hillsboro sits lower than surrounding communities, and the fog that pools here from November through March keeps chimney crowns saturated for longer periods. That saturation, combined with freeze-thaw cycles, turns hairline cracks into water highways in two to three seasons rather than the five to seven we’d expect in drier microclimates.
• Rust-perforated prefab caps in 97124 tract homes. The zero-clearance fireplaces installed during the Intel housing boom came with minimal-specification galvanized caps that were never designed for twenty years of Pacific Northwest exposure. We’re replacing these by the dozen in neighborhoods around Ronler Acres, where the original equipment has simply dissolved.
• Improperly sized replacement caps from prior contractors. Because Hillsboro’s housing spans two distinct construction eras, we’ve found caps jammed onto flues they don’t fit, mesh screens blocking draft on high-efficiency systems, and DIY installations with no storm collar or proper fastening. A cap that doesn’t fit is worse than no cap, it traps moisture and creates a false sense of security.
• Crown wash erosion on pre-1980 masonry. The older homes near downtown Hillsboro and along Baseline Road often have crown washes, thin mortar layers rather than poured concrete crowns. These erode to nothing over decades, exposing the flue and allowing water straight into the chimney structure. We catch this during routine inspections and rebuild with proper concrete crowns before the damage requires structural repair.
