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 Ashburn: What to Know First
We provide independent Famco chimney cleaning and sweep services in Ashburn, with most Level 1 and Level 2 inspections completed in a single visit and straightforward pricing agreed before we start. A standard Famco flue cleaning runs $189-$289 depending on creosote buildup and access, and we do not recommend work you cannot see for yourself on camera. This page is for Ashburn homeowners who own a Famco chimney cap, damper, or venting product and need a sweep or inspection done by technicians who know the brand’s quirks rather than learning on the job. Call (571) 701-8135 to speak with a live person - any hour, any day.
How Famco Products Fail - and How We Fix Them
- Famco 4″-12″ round chimney caps with mesh screens - The 304 stainless mesh on caps installed in Ashburn’s oak-heavy neighborhoods like Belmont Greene and Ashburn Farm tends to clog with leaf debris and creosote flakes faster than comparable Gelco units because the mesh angle is shallower. Water pools, freezes in January thaws, and warps the screen frame. We remove the cap, burn off creosote in a controlled setup, straighten or replace the mesh, and reset with a bead of HeatShield crown seal if the crown is cracked.
- Famco WD series top-sealing dampers - The cast-aluminum throat plate corrodes at the pivot pin after 8-12 years of Virginia humidity cycling, especially in homes near the Broad Run watershed where groundwater moisture wicks up masonry. The plate hangs open a finger’s width, bleeding heated air and letting rain in. We camera-inspect the throat, quote a new Famco damper or a Copperfield cast-iron equivalent if the frame is still square, and seal the mount with refractory mortar.
- Famco B-Vent gas venting (3″-8″ diameters) - The inner aluminum liner dimples at elbow joints in older Ashburn townhomes where original installers used too short a radius. During a sweep we run a video scope through each elbow; dimpling beyond 15% of diameter means the joint is drafting poorly and collecting condensation. We replace the elbow with a DuraFlex smooth-wall section where code allows, or document the finding for the homeowner’s insurance if replacement is deferred.
- Famco SD2 and SD3 wall-mounted exhaust vents - The flapper seal gasket hardens after five Virginia summers, and the spring loses tension. Ashburn homeowners notice this first as a cold draft or, worse, as a bird nesting in the open throat. Our cleaning includes gasket inspection; if it’s rock-hard, we source the Famco OEM gasket kit rather than jury-rigging a universal fit that voids any remaining warranty.
- Famco chimney pots (terracotta and concrete composite lines) - The base flange cracks where it meets the flue tile in homes north of Route 7 that saw the 2011 earthquake aftershocks. Water enters the crack, freezes, and spalls the pot from below. We remove the pot during sweep access, assess the flue tile crown with our camera, and reinstall with a stainless band and HeatShield crown coat - or recommend replacement if the pot is too far gone.
Our Famco Chimney Cleaning & Sweep Process
- 1
Call intake. A live person answers, notes your Famco model if you know it, and books a window. We confirm our $89 Seasonal Tune-Up or standard sweep rate applies.
- 2
Arrival and protection. Our technician lays floor and furniture protection, then runs a Level 1 or Level 2 inspection per NFPA 211. For Famco B-Vent or damper jobs, we bring the camera every time.
- 3
Diagnosis with documentation. We photograph what we find and explain it in plain English. If your Famco cap mesh is warped or the damper plate is corroded, you see it on screen before we quote.
- 4
Parts decision. We stock Famco-compatible components and also carry DuraFlex, HeatShield, Gelco, and Copperfield alternatives. We recommend OEM when it matters for warranty, quality aftermarket when it performs the same for less.
- 5
The work and test. We complete the sweep, repair, or replacement, then run a draft test and final camera pass. The flue doesn’t lie - and neither do we.
- 6
Written guarantee. You get the 90-Day Done Right Promise on every job, backed in writing with no paperwork and no arguing. We clean up and leave the work area as we found it.

FAQs
No. As an independent Famco service provider, we use OEM parts where warranty preservation matters and document everything with photos. Famco’s residential warranty covers manufacturing defects, not who sweeps the flue. If your product is still under warranty, we note the serial number and install date so any future claim is clean.
Most Level 1 sweeps take 45 minutes to an hour and a half. A Level 2 camera inspection on a Famco B-Vent system with multiple elbows runs closer to two hours. We complete most jobs in a single visit, and we book enough time that we’re not rushing to the next call.
If the frame is square and the throat is clean, a new plate and pivot kit usually solves it for half the cost of a full replacement. We camera-inspect first and show you the frame condition. If it’s warped or the seat is eroded, we quote a new unit honestly - no point throwing parts at a lost cause.
Once a year for wood-burning systems, per NFPA 211. Gas Famco B-Vent systems should be inspected annually and swept as needed - usually every two to three years unless you’re seeing soot stains or draft issues. Ashburn’s hard water and humid summers accelerate corrosion in gas vents, so we check seals and elbows carefully.
Stage 1 creosote becomes Stage 3, which is nearly impossible to remove without chemical treatment or a rotary flail. In a lined system, that buildup can ignite at 451 degrees and damage your Famco cap or liner. In an unlined chimney, it risks a house fire or carbon monoxide intrusion through cracked mortar. The camera inspection removes the guesswork - call (571) 701-8135 for a free estimate and see what you’re dealing with.
