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.
Copperfield Chimney Cap Installation: The Leesburg Owner’s Guide
We install Copperfield-compatible chimney caps throughout Leesburg for $340-$680, parts and labor included, and we stock the common sizes on our trucks. Most Leesburg homes built between 1985 and 2010 with factory-built fireplaces use Copperfield caps in 8″×13″, 13″×13″, or 13″×18″ flue dimensions. Russell Haines has fitted hundreds of these on the older colonials near Morven Park, where winter wind gusts off the Potomac ridges test every seam.
Homeowners usually discover a cap problem two ways: water stains on the firebox ceiling after a hard Leesburg rain, or a neighbor pointing out the cap is sitting crooked after a March windstorm. Sometimes it’s a squirrel scrambling down the flue because the mesh has rusted through at the corners. The cap is out of sight, so it fails out of mind until something forces the issue.
Which Copperfield Models This Applies To
Copperfield caps fall into three families, and knowing which you have saves a return trip. The 300-series galvanized caps were common on builder-grade homes in the 1990s; the 500-series stainless came in during the 2000s upgrade cycle; and the 700-series with welded seams is what we recommend for replacement in Leesburg’s freeze-thaw climate. Check the stamp on the crown skirt or measure the flue opening directly. A 300-series cap on a 13″×18″ flue measures roughly 15″×20″ overall; the 500- and 700-series add an inch for the drip edge.
We are an independent service provider, not affiliated with Copperfield Supply. That matters because we can source OEM Copperfield caps or match your flue with a Gelco or Famco equivalent that outlasts the original. The 300-series galvanized shell typically rusts through in 8-12 years in Loudoun County’s acid-rain pattern; a 700-series stainless or Gelco replacement often runs 20 years. We carry both on the truck and will show you the difference before you decide.
Signs Your Copperfield Chimney Cap Is Failing
- Rust streaks down the chimney face. Galvanized 300-series caps lose their zinc coating first at the mesh-to-skirt weld. Once water reaches bare steel, it bleeds orange down the brick. In Leesburg, we see this accelerate after winters with heavy road-salt spray from nearby Route 7.
- Water in the firebox or a damp, musty smell in summer. The cap’s crown has cracked or the storm collar has lifted. Copperfield 300-series crowns are stamped single-piece; they fatigue at the corners after 10-15 years of thermal cycling.
- Mesh sides bowed outward or detached. This is the spark-arrestor screen pulling free from its frame. On 500-series caps, the spot-welds corrode where creosote condensation collects. A gap larger than a quarter inch lets embers escape and violates Fairfax County’s wildland-urban interface code, which Leesburg adopted by reference in 2019.
- Cap shifted or missing after wind. The 300-series uses three sheet-metal screws into the flue tile; the 700-series uses a compression band. Screws strip in soft clay flue liners, common in Leesburg’s 1960s-1980s housing stock. A cap gone walkabout often dents the shingles below.
- Animals or nesting debris in the flue. Mesh with 5/8″ openings blocks squirrels but not bats; 3/4″ mesh blocks neither. Copperfield’s standard is 5/8″, but some aftermarket replacements run larger. We check mesh size during every cap inspection.
Replacement Cost & What’s Included
| Cap Type | Installed Price | Typical Lifespan |
|---|---|---|
| Galvanized 300-series (OEM match) | $340-$420 | 8-12 years |
| Stainless 500-series (OEM match) | $480-$580 | 15-20 years |
| Stainless 700-series or Gelco equivalent | $560-$680 | 20+ years |
| Flue tile repair / screw hole patching | $80-$150 additional | - |
What drives the range: flue accessibility (steep roof pitch adds time), whether the flue tile needs patching where old screws pulled out, and whether you want the spark-arrestor mesh in standard or fine (1/2″) weave. We photograph the condition before we quote. The number on the estimate is the number on the invoice. Every cap installation carries our 90-Day Done Right Promise, in writing, no arguing.
DIY or Call Us?
You can safely check three things from the ground with binoculars: whether the cap is centered, whether mesh panels are intact, and whether rust streaks are present. Do not climb the roof. Chimney work above 15 feet on a pitched surface is where homeowners get hurt, and Leesburg’s older homes with 10/12 or 12/12 pitches near the historic district are unforgiving.
DIY replacement goes wrong in predictable ways. The wrong screw depth cracks flue tile. A cap sized to the chimney crown instead of the flue opening leaves a gap that funnels water. The mesh orientation blocks draft if reversed. We complete most cap replacements in a single visit, with the right ladder, the right anchor hardware, and a level.

FAQs
Galvanized caps last 8-12 years in Loudoun County’s climate; stainless models run 15-20 years or more. Acid rain and freeze-thaw cycling are the wear factors here, not just age. Call (571) 701-7519 and we’ll inspect what you have.
Mesh can be spot-welded and crowns can be sealed in limited cases, but we rarely recommend it. The labor to repair approaches replacement cost, and the underlying metal is already fatigued. We show you photos and give a straight verdict.
Most replacements take 45-90 minutes on site, including removal, flue inspection, and installation. We bring multiple sizes on the truck so we’re not making a second trip. Background-checked, uniformed technicians; most jobs completed in a single visit.
We stock 8″×13″, 13″×13″, and 13″×18″ stainless caps compatible with Copperfield flue dimensions, plus Gelco and Famco equivalents. Odd sizes or custom crowns we order with 2-3 day turnaround. Call (571) 701-7519 to confirm fitment.
