Call (866) 580-4069 - a live person answers, day or night.
We’ve been driving out to Radnor Township from Philadelphia for over 42 years. We know the narrow lanes off Old Lancaster Road, the tight turnarounds by the Radnor Trail, and the parking realities around Wayne’s commercial core. More importantly, we know your chimneys. The fieldstone and brick manor homes that define this stretch of the Main Line were built with multi-flue stacks that served two, three, sometimes four fireplaces - and most still run on original clay tile liners that have never been replaced. That context changes everything about how we inspect, fit, and seal your cap and crown.
Our Chimney Cap & Crown team treats Radnor as a core service area, not an afterthought. When you call, we don’t route you through a national dispatch center. You get our local office, a scheduled arrival window we honor, and a technician who arrives with the right materials for a 1920s Tudor stack - not a one-size-fits-all box from a hardware chain.
Why Hearthstone Chimney Co. of Philadelphia Is Radnor’s Preferred Chimney Cap & Crown Company
Radnor homeowners have long memories. They remember which contractors showed up on time, which ones left a mess, and which ones stood behind their work when something wasn’t quite right. We’ve been earning that reputation since 1984. Carl Bridwell built this company on the K.E.Y.S. code - Krafted right, Every time, Your home first, Standing behind it - and we still answer the phone with a live person 24 hours a day, 7 days a week.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. On a recent call near the Willows estate, we documented crown spalling so severe that rainwater had saturated three feet of the surrounding masonry. The homeowner saw the footage, understood the repair scope, and approved the work. No surprises on the bill. The number on the estimate was the number on the invoice.
Response time to Radnor is typically same-day or next-day for cap and crown issues, and emergency calls - water pouring down the flue, animals entering the stack - get prioritized. Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, Gelco, and other trusted brands. Most jobs finish in a single visit.
We also honor our standing offers: $50 off any repair over $250, a free second opinion on any written estimate, an $89 seasonal tune-up, and a permanent 5% senior and veteran discount. The 90-Day Done Right Promise backs every job in writing. If it’s not right, we come back. No paperwork, no arguing.
Our Chimney Cap & Crown Services in Radnor
Multi-Flue Cap Installation & Replacement
Radnor’s estate homes weren’t built with standard single-flue chimneys. The typical property in Wayne or along the wooded corridors near the Radnor Trail has a central stack serving multiple fireplaces, each with its own flue. A multi-flue cap is non-negotiable here - and it must be measured, fabricated, and fitted to your specific stack dimensions, not pulled from a warehouse shelf.
We source custom multi-flue caps from Copperfield and Famco, sized to cover two to four flues with proper clearance and integrated mesh screening. On one recent job off King of Prussia Road, we replaced a rusted galvanized cap that had been letting squirrels nest between flues for two seasons. The new stainless unit sealed the entire stack top and eliminated the drafting problems the homeowner had been fighting.
Crown Repair & Crown Coating
The mortar crown is your chimney’s roof. When it cracks - and in Radnor, the freeze-thaw cycle between November and March makes cracking inevitable on unprotected century-old crowns - water penetrates straight into the masonry and down your flue liners.
We evaluate every crown with a camera inspection before recommending repair or coating. Minor cracking and surface spalling often respond to a professional crown coating with HeatShield CrownSaver or Gelco products, applied after grinding out damaged material. This runs less than half the cost of a full rebuild and extends serviceable life by a decade or more. For crowns with structural failure - common on 1900s fieldstone stacks where the original pour was thin or unreinforced - we remove and rebuild with proper slope, drip edge, and reinforcement.
Custom Cap Fabrication
Some Radnor stacks defy standard sizing. Tapered stone courses, decorative corbelling, or irregular flue spacing mean a catalog cap won’t seat properly. We measure on-site, fabricate to order, and return to install - usually within one week. Copper and stainless steel are both available; copper weathers to the green patina that complements Radnor’s stone architecture, while stainless offers lower maintenance.
Cap & Crown Inspection with Level-2 Camera
Before we quote any cap or crown work, we inspect. Our Level-2 internal camera survey shows the condition of your flue liners, the crown underside, and the smoke chamber - the areas you can’t see from the roof or hearth. In Radnor, where original clay liners are often cracked at mortar joints or spalled from decades of thermal cycling, this inspection frequently reveals that the cap issue is a symptom, not the root cause. We document everything with photos and explain what we’re seeing in plain English.

Trusted Brands We Service in Radnor
We don’t substitute builder-grade materials on historic homes. For cap and crown work in Radnor, we stock and install professional-grade products from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. These are the brands specified by chimney professionals who understand that a cap on a four-flue fieldstone stack in Wayne needs to outlast the homeowner, not just the warranty period. We maintain local inventory of common cap sizes and crown coating materials, which means faster turnaround on standard replacements and no waiting on freight for emergency repairs.
Common Chimney Cap & Crown Problems We See in Radnor Homes
- Freeze-thaw crown spalling on 1900s fieldstone stacks. Radnor’s approximately 45 inches of annual precipitation combined with sustained sub-freezing temperatures from November through March destroys original mortar crowns. The surface flakes, cracks deepen, and water infiltrates the masonry core. We see this on nearly every uncoated crown over 40 years old in the township.
- Uncapped multi-flue stacks allowing rainwater into deteriorating clay liners. When a cap is missing or improperly fitted on a stack serving multiple fireplaces, water saturates the flue system. In Radnor’s older homes with original clay tiles, this accelerates liner degradation and can cause flue gas leakage into adjacent flues - a genuine safety concern that our camera inspections catch before it becomes dangerous.
- Ill-fitting caps on oversized open-hearth fireboxes. Many Radnor Tudors and colonials have original fireplaces with openings larger than modern standards. The negative pressure these create can suck debris past loose or incorrectly sized caps, accelerating creosote buildup and blockage. This is especially pronounced in homes burning seasoned hardwood harvested from their own wooded lots - a common practice here.
- Squirrel and raccoon entry through corroded or displaced caps. The mature oak canopy throughout Radnor Township provides ample wildlife habitat. A compromised cap is an invitation. We’ve removed nests from flues in the North Wayne neighborhood where animals had pulled apart lightweight aluminum caps that were never suited to this environment.

Here’s what Radnor homeowners can expect. These are real ranges based on jobs we’ve completed in the township - not teaser rates that balloon on-site.

What moves the number? Stack height and roof access affect labor time. The condition of existing flue liners may require repair before capping. Custom fabrication always costs more than stock sizing, but on a historic Radnor home it’s often the only correct solution. We provide no-hassle upfront pricing after inspection - the number on the estimate is the number on the invoice. Call (866) 580-4069 for a free estimate.

FAQs - Chimney Cap & Crown in Radnor
If your clay flue liners are cracked, offset, or spalled, a new cap alone won’t solve the underlying problem. We use our Level-2 camera inspection to see inside the flue - if the liner damage is extensive, we recommend liner repair or relining before investing in a premium cap. Call (866) 580-4069 and we’ll show you exactly what the camera sees.
Yes - the high burn volume and long heating season in Radnor mean more creosote production than homeowners expect, even with seasoned hardwood. We specify caps with integrated stainless steel mesh screening sized to allow proper draft while blocking debris and animal entry, and we ensure the cap design accommodates the strong updraft your oversized firebox creates. The right cap reduces maintenance frequency and improves safety.
Two caps usually means two separate flues serving different fireplaces, often added at different times as the home was expanded or modified. We inspect both flues independently - one may be in excellent condition while the other needs extensive work. However, if both caps are aging out (galvanized steel typically lasts 15-20 years in Radnor’s climate), replacing as a matched set ensures consistent appearance and performance. We’ll give you an honest assessment of each.
We don’t recommend DIY cap installation on any multi-flue fieldstone stack, and historic register properties often have additional review requirements for visible exterior changes. The safety risks of working at height on irregular stone courses are real, and an improperly fitted cap can trap moisture or obstruct draft. Our technicians are trained for this specific work, and we document our installations with photos for your records. Call for an estimate - it’s free, and you’ll know the job is done correctly.
Year-round burning in Radnor’s climate means annual crown inspection is prudent. The thermal cycling from repeated heating and cooling, combined with freeze-thaw exposure, accelerates deterioration. We recommend scheduling inspection each spring, after the heavy use season ends, so any damage can be addressed before the next heating cycle begins. Our $89 seasonal tune-up includes crown and cap evaluation.
