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.

AfterFast, Reliable Chimney Liner & Rebuild Across Herndon
If you live in Herndon and you’re staring down a chimney liner quote that’s making your eyes water, here’s the short version: a stainless steel liner replacement in Herndon typically runs $2,300 to $5,800 depending on flue height and access. A partial rebuild of the chimney crown and shoulder usually lands between $1,900 and $3,900. Wendell Pike and the crew at Top Hat Chimney handle both, and we’ll hand you camera footage before we hand you an invoice. Call (571) 518-5470 and we’ll give you an exact number before a single tool comes off the truck.
What makes Herndon different from, say, Alexandria or Falls Church is what was actually built here. We’ll get into that below. But if you’re reading this because you smelled smoke in a room with no fire, or your neighbor’s flue is venting into your townhome, keep reading. That’s a Herndon problem we know well.
Key Takeaways:
- Most Herndon flue work involves retrofitting stainless steel liners into 1980s and 1990s prefab fireplace chases, not repairing brick masonry.
- Shared flues in attached townhomes create cross-contamination risk you can’t see without a camera.
- Freeze-thaw cycling through NoVA winters stresses chimneys faster here than in Richmond, and older crowns near downtown Herndon take the brunt of it.
- Every job comes with the 90-Day Done Right Promise in writing, and a live person answers the phone around the clock.
Why Top Hat Chimney Is Herndon’s Preferred Chimney Liner & Rebuild Company
Top Hat has been sweeping and rebuilding chimneys since 1999, and Wendell still runs every job himself. That matters in Herndon because this town’s chimneys are mostly factory-built metal fireplaces from the Dulles Technology Corridor boom years. A franchise crew that trained on brick fireplaces in another state will misread what they’re looking at.
Herndon homeowners call us because we publish our name and license number, quote a flat price on the phone, and back the work with a written 90-Day Done Right Promise. If it’s not right, one call brings Wendell back. No argument, no dispatcher runaround.
We answer the phone at (571) 518-5470 with a live person every time. Not a voicemail box. Often it’s Wendell himself. And when the sweep shows up at your door in Herndon, he’s background-checked, in uniform, and he’ll give you a real arrival window that doesn’t slip without a phone call first.
Since this community was built almost entirely between 1975 and 1995, we’ve spent decades working the same subdivision layouts: Chandon, Hunters Creek, and the older brick pockets near downtown. That’s not something a national chain rotating crews through NoVA can say.
Our Chimney Liner & Rebuild Services in Herndon
Stainless Steel Liner
Most Herndon homes built in the 1980s and 1990s have prefab fireplaces with thin-wall flue pipe that’s now 30 to 50 years old. That pipe corrodes from moisture trapped during decades of light use. We install stainless steel liners sized to the existing chase, which means no demolition of your drywall or siding in most cases. A typical stainless liner install in a Herndon colonial runs $2,600 to $5,200.
Flexible Liner
When the chase has bends or offsets, a rigid liner won’t fit without cutting into framing. That’s where flexible stainless liners come in. We use trusted brands like Copperfield and Olympia Chimney, and we don’t guess on sizing. We measure with a camera first, then pull the liner accordingly. Herndon split-levels and colonials from the Dulles era frequently have exactly this problem.
Liner Replacement
If your current liner is cracked, corroded, or undersized for a new gas insert, replacement is a straight mechanical job that we usually complete same-day. In Herndon, the most common replacement we see is a single-wall flue in a 1985-to-1992 home that’s rusted through near the chase top. We’ll show you the camera footage before we quote. You’ll see the hole yourself.
Partial Rebuild
The chimney crown on an older Herndon colonial near downtown takes repeated freeze-thaw abuse all winter long. Water gets into the crown, freezes, expands, and the mortar crumbles. We rebuild crowns and shoulder courses without tearing down the entire chimney. A partial crown rebuild in Herndon typically runs $1,900 to $3,400, and it’s the single best dollar you can spend to avoid a full rebuild later.
Our full Chimney Liner & Rebuild team handles everything from a simple crown patch to a full flue retrofit. When you call about Chimney Liner & Rebuild in Herndon, you’re talking to the crew that’s been inside these specific chases for years.

Trusted Brands We Service in Herndon
We install and service liners and components from Copperfield, Olympia Chimney, and Gelco because these brands hold up to NoVA’s moisture and high-heat cycles. If a Herndon homeowner has an existing Gelco liner that’s nearing end of life, we’ll know it by the stamping before we even pull it. We stock common parts for Herndon jobs and can usually start work within a few days of the estimate.
Common Chimney Liner & Rebuild Problems We See in Herndon Homes
- Shared flue cross-contamination in attached townhomes. When a neighbor vents a wood stove into a shared stack, the smoke has to go somewhere. We find smoke and carbon monoxide pushing into adjacent units more often than homeowners expect. A separate liner for each flue is the fix.
- Corroded thin-wall flue pipe in 1980s prefabs. Herndon’s tech-sector homeowners often didn’t burn for 15 or 20 years during peak career years. Moisture sat in those flues. Now the pipe is rusted through and the first cleaning appointment turns into a liner replacement.
- Cracked refractory panels and warped dampers. These are fireplace-specific failures, not chimney failures. A cracked panel lets heat reach the chase framing. A warped damper lets conditioned air leak out all year. Both require a camera inspection to catch.
- Freeze-thaw crown erosion near downtown Herndon. The older masonry chimneys around Elden Street and the historic core see dozens of freeze-thaw cycles every winter. Mortar joints and crowns break down faster than in towns with steadier winter temperatures.

FAQs - Chimney Liner & Rebuild in Herndon
You need your own liner if your fireplace or appliance vents into a shared stack alongside a neighbor’s unit. Shared flues are common in Herndon’s attached townhome stock from the 1980s, and when one side burns, the smoke can push into the other side. A separate stainless steel liner down each flue solves it. We’ve done this exact job in Hunters Creek, where we found a shared flue serving two adjacent fireplaces. Two Copperfield liners and a rebuilt crown sealed the cross-contamination for good. Call (571) 518-5470 and we’ll camera-scope yours and tell you what’s actually there.
Because the thin-wall flue pipe in those factory-built units corrodes from trapped moisture and high heat cycling over 30 to 50 years. Cleaning removes creosote, but it won’t fix a rusted-through pipe or a cracked refractory panel. Herndon’s housing stock, built almost entirely with zero-clearance metal fireplaces between 1975 and 1995, hits this wall constantly. Once the liner is compromised, replacement is the only safe fix.
Yes. If the flue liner is still sound, we can patch or rebuild the crown and shoulder courses alone, usually for $1,900 to $3,400. We’ll camera the flue first so you see exactly what’s damaged. No crown work gets recommended without footage you can watch yourself.
Herndon’s winter temperatures cross 32°F dozens of times each season, far more thermal stress than Richmond sees. Every crossing lets water penetrate the crown and freeze, expanding inside mortar joints. Over years, that erodes the crown and pushes water down into the flue. A Richmond chimney may go a decade without crown failure; a Herndon chimney near downtown can lose a crown in five or six years if it’s not maintained. Different climate, different failure pattern.
For a gas insert in an older Herndon prefab, we recommend a stainless steel liner sized to the insert’s BTU output and the existing chase. Flexible stainless works well in chases with offsets, which many 1980s split-levels have. We’ll match the liner to your insert and the chase dimensions, then show you the install on camera. Call (571) 518-5470 and we’ll walk you through what fits your setup before you spend a dollar.
If you live in Herndon and your chimney is due for a hard look, call (571) 518-5470. Wendell or one of the crew will answer, talk through what you’re seeing, and book a time that works. Free estimate, flat price, and the footage to back it all up.
