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.
Famco Chimney Cap & Crown in Fairfax: What to Know First
We repair, replace, and install Famco chimney caps and crowns in Fairfax, and most jobs are done in a single visit because we stock the common Famco parts on the truck. An honest price range for Famco cap and crown work in Fairfax runs $220 to $1,400 depending on whether we’re replacing a cap, rebuilding a crown, or doing both. If you own a Famco cap or crown and something looks wrong up there, this page tells you what’s actually going on, what it costs to fix, and when it can wait. Call (571) 624-2385 for a straight answer and a free estimate.
How Famco Products Fail - and How We Fix Them
- Famco’s galvanized multi-flue caps pull loose at the corner seams. The older FC-series caps used riveted corners, and after five or six Fairfax winters, the rivets stretch. The cap still looks fine from the ground, but it rattles loose and lets rain run down the flue walls. We re-secure the corners with stainless hardware or replace the cap if the metal’s too far gone, and we always check the attachment point on the flue tile while we’re there.
- The single-flue caps with the mesh banding plug up faster than people expect. Famco’s mesh is tight enough to keep squirrels out, which is good, but in Fairfax neighborhoods with old oaks and maples, the mesh loads up with helicopter seeds and fine soot by mid-season. A plugged mesh is a draft killer. We clean the mesh and check the lid clearance so the flue can breathe.
- Famco crowns are solid, but the original mortar joints under them are not. This is the thing nobody tells you. The crown can be in perfect shape while the wash underneath has cracked away from the flue tile. Water gets under the crown, freezes, and lifts the whole assembly. We pull the crown, re-point the wash, seal the joint with a flexible crown coat, and re-set the crown. You do not always need a new crown. Sometimes you need a new foundation under it.
- The Leg Support models shift when the flue tile settles. Famco caps that mount with leg supports rely on flush contact with the flue tile. Fairfax homes built in the 60s and 70s, especially over near the Government Center area, have flue tiles that have settled a quarter inch or more over decades. The cap sits cockeyed. Wind grabs it, and the legs chew into the tile. We re-level with stainless shims or switch you to a top-mount adapter when the tile can handle it.
- Warranty-safe parts decisions matter more than people think. Famco warranties cover manufacturing defects, not installation or weather wear. When we replace a part, we tell you straight whether an OEM Famco part is worth the wait and cost or whether a quality aftermarket stainless piece gives you better value. If it’s under active warranty, we’ll work with the OEM part so we don’t void anything. Independent Famco service means we can give you that choice honestly, without a manufacturer rep standing over our shoulder.
Our Famco Chimney Cap & Crown Process
- 1
You call, we pick up. A live person answers, day or night. We talk through what you’re seeing, and if it sounds like a Famco cap or crown issue, we’ll give you a ballpark number right then. The price you hear on the phone is the price on the invoice.
- 2
Wendell or one of the crew climbs up and gets eyes on it. Not a drone, not a foam-sales inspection. We get on the roof and look at the cap, the crown, the wash, and the flue tile. We take photos, and if there’s any question about what’s wrong, we run a camera down the flue.
- 3
You get a plain-English verdict. We show you the pictures. If the Famco cap is fine and the crown just needs a coat of sealant, you’ll hear that. If it does not need doing, we will tell you that too.
- 4
We agree on the fix, and the number doesn’t change. OEM or aftermarket parts, one person’s opinion, no add-ons when the invoice comes out.
- 5
We do the work, clean up, and test it. Cap is set level, crown is sealed, and we check the draft before we leave the roof.
- 6
You get the 90-Day Done Right Promise in writing. If something’s not right, one call brings us back. No charge, no argument.

FAQs
No, replacing a Famco cap with a warranty-compatible OEM or approved comparable part does not void an active Famco warranty. If your cap is under active warranty, we use OEM parts so the coverage stays intact. If it’s out of warranty, we’ll give you the straight comparison between OEM cost and a quality aftermarket stainless part.
Most Famco cap replacements are done within three to five business days of your call, and commonly in one visit if we have the right size on the truck. Custom multi-flue caps can take a week to fabricate. Call (571) 624-2385 and we’ll give you a real arrival window, not a four-hour “somewhere between noon and whenever.”
Not always. A rusted Famco cap does not automatically mean the crown underneath is compromised. We inspect both, and if the crown is structurally sound with only minor surface cracks, we’ll coat it and replace just the cap. You only pay for what actually needs doing.
Water gets into the crack, freezes in a Fairfax January, and forces the crack wider. Repeat that for a season or two and the crown starts spalling, which means chunks of it start breaking off and falling into your yard or onto your roof. The flue tile underneath gets exposed, and that’s when the repair bill doubles. Crown damage is always cheaper to fix early than to rebuild late.
Yes. We custom-fabricate multi-flue caps when the pre-made Famco sizes don’t fit, especially on older Fairfax homes where the flue spacing is not standard. We’ll measure on-site and get you a cap that seals correctly instead of forcing a stock size that leaves a gap.
