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.
Trusted Chimney Cap & Crown for Leesburg Homeowners
Chimney cap and crown repair in Leesburg typically costs between $180 for a basic cap replacement and $1,400 for full crown reconstruction, with most jobs completed in a single visit. Hearthstone Chimney Co. has installed and repaired caps and crowns across Loudoun County for over 42 years, and we back every job with our 90-Day Done Right Promise in writing. Call (571) 701-7519 and you’ll reach a live person, 24 hours a day.
Leesburg’s freeze-thaw winters and summer thunderstorms punish chimney caps and crowns harder than most homeowners realize. Water gets behind a cracked crown, freezes overnight in January, and by March you’ve got spalling brick and a leak path into your attic. We’ve replaced caps in the Belmont neighborhoods after wind events tore off cheap builder-grade units, and we’ve rebuilt crowns in the historic district near Tutt Lane where decades of neglect finally showed up as interior water stains. Russell Haines started this company in 1984 with the belief that a chimney repair should last longer than the warranty, and that still governs how we work.
Our technicians arrive in uniform, background-checked, with a Level-2 camera and photos you’ll see before any work begins. No surprises on the bill. The estimate number matches the invoice number. That’s the Keystone Standard we’ve operated by for four decades.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is the first defense against rain, animals, and debris entering your flue. In Leesburg, we see too many uncapped flues in homes built during the 1980s and 1990s construction boom, especially in the Cascades and Brambleton areas where builders skipped this detail to cut costs. We measure your flue precisely, fabricate or source a cap with proper mesh screening to stop squirrels and birds without restricting draft, and secure it with stainless steel fasteners rated for our wind exposure zone. Most installations take under two hours and come with our 90-Day Done Right Promise.

Cap Replacement
Existing caps rust, warp, or blow off in Leesburg’s spring windstorms. We remove the failed unit, inspect the flue tile and crown surface beneath for hidden damage, and install a replacement that actually fits. Last October we replaced three caps on Falcon Ridge Drive after a single storm, all from the same batch of galvanized hardware-store caps that lasted less than five years. We use professional-grade materials from Olympia Chimney and Famco, never the thin-gauge products that fail at the seams.

Crown Repair
The concrete crown sits at the top of your chimney, sloped to shed water away from the flue. When it cracks, water penetrates directly into the chimney structure. In Leesburg’s climate, a small crown crack in October becomes a structural problem by April. We grind out deteriorated concrete, apply a bonding agent, and pour new high-strength crown mix with proper overhang and drip edge. For crowns with minor cracking but sound structure, we offer crown coating as a preventive option.

Crown Coating
Crown coating is a flexible, waterproof membrane applied over sound but weathered concrete to extend service life five to ten years. We use professional-grade formulations designed for chimney exposure, not generic elastomeric roof coatings that can’t handle the temperature cycling. This makes sense for Leesburg homeowners with crowns showing hairline cracking but no spalling or structural separation, particularly on homes in Sterling and Herndon built in the 1970s with solid but aging masonry. We photograph the crown condition before and after so you can see exactly what was addressed.

Multi-Flue Cap
Homes with multiple fireplaces or a fireplace and furnace sharing one chimney need a multi-flue cap that covers the entire crown surface with proper clearance for each flue. These are custom-fabricated to your chimney’s exact dimensions. We’ve installed multi-flue caps on large homes near Morven Park and in the Great Falls area where two or three flues exit a broad crown. The design must account for proper draft for each appliance, or you’ll get smoking fireplaces or backdrafting water heaters.

Custom Cap
Some Leesburg chimneys need what doesn’t come off a shelf: oversized flues, unusual shapes, or architectural requirements in historic districts. We measure, sketch, and fabricate custom caps in copper, stainless steel, or black galvanized finish to match your home’s character. A custom cap on a historic home near the courthouse took three weeks from measurement to installation last year, but it’ll outlast the roof. We work with Copperfield for specialty fabrications when the job demands it.

Brands We Service for Chimney Cap & Crown
We’ve installed and serviced hundreds of Olympia Chimney caps across Loudoun County. Their stainless steel models hold up to our freeze-thaw cycles without the seam separation we see in lesser brands, and we stock common sizes for same-day replacement on standard flues. Famco’s multi-flue and custom cap lines give us reliable fabrication specs for complex jobs, and their powder-coated finishes resist the UV degradation that chalks cheaper caps in three summers.
Copperfield supplies our specialty hardware, custom flashings, and crown repair materials when a standard solution won’t do. We’ve used their fabrication services for heritage-style copper caps in Leesburg’s historic district and for oversized units on estate homes near Purcellville. Whether you have Olympia Chimney, Famco, Copperfield, or any other make on your chimney, we can service it, replace it, or improve on it with components that actually last.
Signs You Need Chimney Cap & Crown Right Now
- Water stains on the ceiling near your fireplace. This means water is already past the crown and working through the masonry. In Leesburg’s winter, that moisture freezes and expands, accelerating damage. We see this most in homes with original caps from the 1990s that have rusted through at the seams.
- Rust streaks down the chimney face. Orange or brown staining on brick or siding below the chimney top signals a failing cap or deteriorated crown edge that’s letting water reach metal components. The rust is evidence, not the problem itself. Left alone, it leads to spalling brick and mortar joint failure.
- Animals or nesting debris in the flue. Squirrels, raccoons, and chimney swifts enter through missing or damaged caps. A Leesburg homeowner on Catoctin Circle heard scratching for two weeks before calling; the nest partially blocked the flue and created a real carbon monoxide risk. A proper cap with correctly sized mesh prevents this entirely.
- Visible cracks or crumbling on the crown surface. Stand back from your house with binoculars. If the crown looks weathered, has vegetation growing from cracks, or shows pieces missing, water is already infiltrating. Crown cracks never heal themselves. They widen with every freeze cycle.
- Draft problems or smoky fireplace operation. A cap that’s too small, improperly installed, or missing its mesh can create downdraft issues in Leesburg’s windy locations, particularly on homes above the floodplain with exposure from the northwest. The cap must suit the flue and the local wind pattern, not just cover the hole.

How Much Does Chimney Cap & Crown Cost in Leesburg?
A standard single-flue cap replacement in Leesburg typically runs $180 to $450, depending on flue size, cap material, and whether the flue tile needs repair before installation. Crown coating for sound but weathered concrete averages $400 to $700. Full crown reconstruction on a typical residential chimney ranges from $800 to $1,400, with larger or multi-flue crowns running higher. Custom fabricated caps, particularly in copper or for non-standard dimensions, start around $600 and scale with complexity.
Several factors move the price. Accessibility matters: a steep roof or chimney location away from ladder placement adds time and safety equipment. The extent of hidden damage beneath a failed cap or crown can require additional masonry repair. Material choice affects longevity as much as cost, a stainless steel cap from Olympia Chimney costs more than galvanized but lasts decades longer in Leesburg’s climate.
To avoid overpaying, get a written estimate that specifies materials by brand and gauge, not just “new cap.” Ask whether the price includes removal and disposal of the old unit, inspection of the underlying crown, and any flue tile repair. Our estimates include all of this. The number we quote is the number on the invoice. We also offer $50 off any repair over $250, a free second opinion on any written estimate you’ve received, and a permanent 5% senior and veteran discount.
Every estimate is free and carries no obligation. We’ll tell you honestly when a repair can wait a season, and when waiting risks real damage. Call (571) 701-7519 for exact pricing on your chimney.
