We’ve been working on Annandale chimneys for over 42 years. We know the brick ranches off Little River Turnpike, the split-levels tucked behind Annandale Road, and the tight side yards where a ladder barely fits between houses. Our crews serve Annandale locally, with dispatch and scheduling coordinated from our Washington, DC office. When you call, you speak to someone who understands that a rusted cap on a shared stack in this neighborhood isn’t just a water problem - it’s a cross-contamination risk.

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

Annandale homeowners tend to stay put. They’ve lived in the same ranch or split-level for twenty, thirty, sometimes forty years. They’ve watched contractors come and go. They remember the ones who showed up late, billed extra, or disappeared when something failed.

We’re still here. Since 1984. That longevity means something in Fairfax County, where a company that plans to be around in thirty years acts accordingly. Our 90-Day Done Right Promise - Krafted right, Every time, Your home first, Standing behind it - is in writing with no arguing. If it’s not right, we come back. No paperwork shuffle, no runaround.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. When we find third-degree creosote glazing or acidic condensation damage in a shared stack, we document it like an engineer and explain it like a craftsman. Background-checked, uniformed technicians complete most jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. A square deal: no surprises on the bill.

Our Chimney Cap & Crown Services in Annandale

Cap Installation

New cap installation in Annandale’s mid-century housing stock demands more than picking a stock size off the shelf. The original clay pots on these 1955-1975 ranches were never designed for gas-venting temperatures, and many have cracked or been lost to ice storms. We measure each flue precisely, account for proper draft on converted oil-to-gas systems, and specify caps with correct mesh screening to keep out the squirrels and starlings that plague Annandale’s mature tree canopy. A single-flue cap installation in Annandale typically runs $280-$450.

Cap Replacement

We replace a lot of rusted Famco caps and bent no-name hardware-store specials in Annandale. The freeze-thaw cycles here are relentless, and a cap that was “fine” in October is often peeling and leaking by March. When we remove an old cap, we inspect the crown beneath it - because a new cap on a crumbling crown is money wasted. Cap replacement with crown assessment in Annandale generally falls between $320-$580.

Crown Repair

The crown is the concrete or mortar wash that seals the top of your chimney where the flues exit. In Annandale’s housing stock, these crowns were often poured thin, with no overhang, using mortar mixes that weren’t meant to weather Northern Virginia’s freeze-thaw abuse. We see spalling, cracking, and complete separation on chimneys from the Route 236 corridor to the neighborhoods near Backlick Road. Our crown repairs use professional-grade materials formulated for this climate, not bagged concrete from the hardware store. Crown repair in Annandale typically costs $450-$750.

Crown Coating

For crowns with surface deterioration but sound structural integrity, we apply Gelco crown coating - a flexible, waterproof membrane that bridges hairline cracks and sheds water for years. This is often the right call for Annandale homeowners whose crowns are starting to show their age but haven’t yet failed completely. It’s less invasive than a full rebuild, and it buys time on a chimney that’s otherwise sound. Crown coating in Annandale runs $380-$620 depending on surface area and prep work needed.

Multi-Flue Cap

This is where Annandale’s housing density matters most. The attached and closely-spaced homes along the Little River Turnpike corridor frequently share or adjoin venting stacks. A multi-flue cap covers all flues in a single structure, eliminating the gaps between individual caps where water, debris, and - critically - neighboring exhaust can infiltrate. We size multi-flue caps to maintain proper draft on each flue while sealing the entire crown perimeter. Multi-flue cap installation in Annandale typically ranges from $580-$850.

Custom Cap

Some Annandale chimneys need what doesn’t exist in a catalog: oversized flue combinations, unusual chase dimensions, or heritage-compatible designs for homes in established neighborhoods. We fabricate custom solutions using measurements taken on-site, not guesses from satellite photos.

Trusted Brands We Service in Annandale

We don’t use builder-grade substitutes. For Annandale’s chimneys, we specify Gelco crown coating for its flexibility in freeze-thaw conditions, Famco caps for their galvanized and stainless-steel construction that outlasts the box-store alternatives, and Olympia Chimney components where factory-built chase applications call for exact-fit parts. We stock common sizes and configurations locally, so most Annandale cap and crown jobs don’t wait on shipping. When a rusted cap is letting water into your firebox the week before Thanksgiving, that turnaround matters.

Common Chimney Cap & Crown Problems We See in Annandale Homes

• Shared-stack cross-contamination. Annandale’s 1955-1975 ranch and split-level belt along the Route 236/Little River Turnpike corridor means attached and closely-spaced homes frequently share or adjoin venting stacks, so a next-door neighbor’s gas furnace or water heater can backdraft into your flue through a shared masonry chase. When we replace a cap or pour a crown here, we treat it as a cross-contamination issue, not just a weatherproofing one.
• Freeze-thaw crown spalling. Northern Virginia’s winters keep temperatures hovering near the freezing mark for extended stretches, delivering repeated freeze-thaw cycles each season that are especially punishing to the aging mortar crowns and spalling brick in Annandale’s mid-century chimneys. A crown that looks merely “weathered” in September can be shedding chunks by April.
• Ice-storm cap damage. Occasional heavy ice storms - a recurring feature of the DC metro’s winter weather - add impact damage to chimney caps and unsupported clay pots that are already weakened by decades of thermal cycling. We’ve retrieved caps from Annandale side yards and even neighboring roofs after a bad storm.
• Oil-to-gas flue mismatch. A significant share of Annandale’s ranch and split-level owners converted from oil to gas heat in the 1980s-90s, leaving behind oversized flues originally sized for high-temperature oil burners now venting cooler gas appliances. That mismatch accelerates acidic condensation inside the liner and creates a Fairfax County code-compliance problem that sweeping alone won’t resolve. The right cap and crown work can’t fix an oversized flue, but it can prevent the condensation damage from compounding.
