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.

AfterFamco Chimney Cleaning & Sweep in Manassas: What to Know First
We provide independent Famco chimney cleaning and sweep services in Manassas, with most Level 1 and Level 2 inspections completed in a single visit and pricing agreed before we start. A standard Famco sweep and inspection runs $180-$290, while jobs needing creosote removal with rotary cleaning or Level 2 camera documentation range $250-$420. We’re not here to sell you a liner you don’t need. If the flue is clear and the mortar is solid, we’ll tell you that. If it isn’t, we’ll tell you that too.
This page is for Manassas homeowners with Famco chimney caps, dampers, or venting products who want the flue inspected and cleaned by technicians who know the difference between a Famco 304 stainless cap and a generic big-box substitute. Call (571) 586-0593 - a live person answers, 24 hours a day.
How Famco Products Fail - and How We Fix Them
- Famco 304 stainless chimney caps warp at the seams after 8-12 winters in Manassas. The freeze-thaw cycle here, with temperatures swinging from single digits to 60°F in a February week, works the seam welds until they gap. We spot this during every Level 2 inspection with camera verification, then replace with a properly spec’d Famco cap or fit a DuraFlex equivalent that matches the flue diameter exactly - no caulk-and-hope.
- Famco WC wind-directional caps seize in the “closed” position after pollen season. The brass bushing in the WC series binds up when oak and pine pollen mix with creosote film, common in Manassas homes near the battlefield park’s mature canopy. We disassemble, clean the bushing with a non-corrosive solvent, and relubricate with high-temp graphite - or replace the bushing assembly if the galling is too deep.
- Famco BD barometric dampers drift out of calibration in high-humidity summers. Manassas July humidity hangs in the 80s, and the BD’s aluminum voxidizes at the pivot point. We remove the damper, clean the pivot with a wire wheel, reset the weight to factory spec, and seal the throat plate if it’s been drawing conditioned air all summer.
- Famco SD self-adjusting dampers accumulate creosote behind the blade where owners can’t see. The SD series hides buildup in the channel behind the closed blade - a spot a flashlight from the hearth won’t reach. Our rotary sweep system pulls that creosote forward, and the camera shows you the before and after. We’ve found SD dampers in Manassas homes with 3/8-inch deposits that the homeowner never suspected.
- Famco GRV galvanized roof vents rust through at the collar in 6-10 years. Manassas gets 42 inches of rain yearly, and the GRV’s lower-gauge galvanizing sacrifices itself at the roof penetration first. We replace with a 304 stainless Famco collar or step up to a Copperfield stainless equivalent with a longer warranty, depending on your roof pitch and vent run.
Our Famco Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, notes your Famco model if you know it, and books a window. We confirm no-hassle upfront pricing before we dispatch.
- 2
Arrival and protect. Our background-checked, uniformed technician lays drop cloths from the door to the hearth and inspects the Famco cap or damper for visible damage from the exterior.
- 3
Level 1 or Level 2 inspection. We run a camera if the flue shows creosote glazing, if the system has been unused for two-plus seasons, or if you’re buying or selling the Manassas home. You see the photos. We explain what needs doing now and what can wait.
- 4
Sweep and service. Rotary or manual sweep depending on creosote grade. Famco dampers are removed, cleaned at the pivot and channel, and reinstalled. OEM Famco parts are used when available; when Famco backorders a cap or bushing (common on WC brass components), we source quality aftermarket from our DuraFlex, HeatShield, or Gelco inventory and tell you before we install.
- 5
Test and document. We burn a smoke pellet to verify draft, photograph the completed work, and leave you a written report with the 90-Day Done Right Promise attached.
- 6
Cleanup and close. Hearth area vacuumed, drop cloths removed, and the estimate you agreed to is the invoice you pay.

Three things move the price: how much creosote is in the flue, whether the Famco cap or damper needs parts, and whether roof access requires our ladder safety setup on a steep pitch. We price it before we start. Call (571) 586-0593 for an exact quote - estimates are free.
Why Manassas Homeowners Call Hearthstone Chimney Co. for Famco Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Manassas in thirty more. That changes how we treat a job. The 90-Day Done Right Promise is in writing with no arguing - if it’s not right, we come back. Our technicians are background-checked, uniformed, and trained on Famco’s product line alongside DuraFlex, HeatShield, and Gelco systems, so we’re not guessing at your venting setup. Most jobs finish in a single visit. And when Russell Haines reviews the camera footage, he reads the flue honestly - what needs doing this season, what can wait, and he means both parts equally.
FAQs
No. As an independent Famco service provider, we perform cleaning and maintenance that does not affect your product warranty, provided we use compatible parts and document the work. We note every service in your written report in case you need warranty support later. Call (571) 586-0593 with your Famco model number and we’ll confirm part compatibility before we book.
Once yearly if you burn regularly during heating season, every two years if the fireplace is occasional. Manassas oak and hickory produce more creosote than the softwoods Russell Haines burned through in his Los Angeles days, and the humid summers let that creosote absorb moisture and harden. Call for a free inspection if you’re unsure - we’ll show you what the camera sees.
We source OEM Famco parts when available and when lead times are reasonable. When Famco backorders a WC bushing or 304 cap collar - which happens - we install quality aftermarket from DuraFlex, HeatShield, or Gelco with equivalent or better specs, and we tell you before we open the package. Nothing goes in your chimney without your okay.
We decide with the camera and the smoke test. If the blade seals, the pivot moves freely, and the throat plate isn’t warped, we service what you have. If the cast iron is cracked or the frame has pulled away from the firebox, replacement is the honest call. You’ll see the photos and we’ll explain both options with prices. Call (571) 586-0593 to schedule.
Stage 3 glazed creosote forms, which restricts draft and can ignite. In Manassas, we’ve removed deposits thick enough to reduce flue diameter by a third. The risk is real but not immediate - we don’t scare-sell. Schedule an inspection and we’ll tell you where you stand. Estimates are free: (571) 586-0593.
