Famco Chimney Cap & Crown Nationwide

Famco Chimney Cap & Crown in San Mateo: What to Know First

We provide independent Famco chimney cap and crown service in San Mateo, with most cap replacements and crown repairs completed in a single visit once parts are confirmed. A written price lands before any work starts, and every job includes a camera-scan inspection with a documented photo record under Clause 4 of the Haven Standard. This page is for homeowners who already know they have Famco hardware on their chimney and need to know whether it can be repaired, what it will cost, and who can do the work without voiding whatever warranty remains.

How Famco Products Fail - and How We Fix Them

• Famco 13×13 and 17×17 galvanized caps - the seam welds at the corner posts crack after 7-12 years in San Mateo’s salt air, especially on homes west of El Camino Real where the marine layer sits heavy. Water wicks through the seam, rusts the interior frame, and the cap starts to rattle in a south wind. We pull the cap, assess the flue tile condition underneath, and replace with a stainless Famco equivalent or a Gelco multi-flue cap if the flue configuration has shifted.
• Famco wind-directional caps (the rotating models) - the brass bushing seizes when creosote dust works into the pivot, common in Baywood homes with older wood-burning fireplaces that see heavy winter use. The cap stops rotating, which means it stops drafting properly, and back-puffing into the living room follows. We disassemble the pivot, clean the bushing with a non-corrosive solvent, and if the housing is scored, we source a replacement pivot assembly through Haven’s buying network rather than replacing the entire cap.
• Famco single-flue caps with mesh sides - the 5/8-inch mesh on the 2008-2016 production run collapses inward when a chimney sweep’s brush catches an edge, a flaw we see regularly on San Mateo chimneys swept by companies that don’t camera-inspect first. The mesh then gaps open, letting squirrels and roof rats straight into the flue. We replace the mesh panel with a heavier-gauge aftermarket equivalent, or if the cap frame is also bent, we spec a new Famco or Olympia Chimney cap with reinforced mesh.
• Famco concrete crowns poured over Famco flue extenders - the extender sleeve is galvanized steel, and when the crown cracks (which it will, given San Mateo’s clay soils and the thermal cycling from Pacific temperature swings), water hits that sleeve and rust-jacks the concrete from inside. The crown spalls in chunks. We cut back to sound concrete, install a poured-in-place crown with a proper drip edge and a bond break around the extender, or switch to a stainless extender if the flue tile is still sound.
• Famco multi-flue caps on 1980s San Mateo tract homes - the original cap was sized for three flues, but one flue was abandoned decades ago and the cap now bridges a dead space that collects condensation. The mounting brackets fatigue, and the cap tilts toward the abandoned flue. We measure the live flue spacing precisely, spec a cap that covers only active flues, and seal the abandoned flue with a HeatShield plug or a concrete capper, depending on whether it might be reopened later.

Our Famco Chimney Cap & Crown Process

1. 1
   Call and scheduling. A live person answers, checks Famco part availability through Haven’s buying network, and books a window. You’ll get a text when your tech is en route.
2. 2
   Camera-scan inspection. We run the camera down the flue before touching the cap or crown. The camera doesn’t guess. Neither do we. Corrine Halstead and her crew have learned that a crown that looks bad from the roof can be protecting sound flue tile, and a cap that looks fine can be masking a cracked flue shoulder.
3. 3
   Written price and scope. You get a written price, written scope, and written warranty before work starts - Haven Standard Clause 1. No exceptions. If you have a competitor’s written estimate, we’ll give you a free second opinion.
4. 4
   Parts decision. We stock common Famco stainless caps and Gelco equivalents. For discontinued Famco lines, we source quality aftermarket through Olympia Chimney or Copperfield, and we tell you explicitly when we’re not using Famco OEM.
5. 5
   Repair or replacement. Caps are installed with proper clearances and storm collar sealing. Crown work follows NFPA 211 guidelines for slope, thickness, and overhang. We photograph every step.
6. 6
   Final camera verification and documentation. We run the camera again to confirm no debris entered the flue during the repair. You receive a photo record, written warranty, and invoice. The 365-Day Done Right Promise applies from that moment.

Our background-checked, uniformed technicians arrive with license information displayed and a text when they’re on the way. Every job carries the 365-Day Done Right Promise, and our documented photo record - standard since 2009, now Haven Standard Clause 4 - means you have evidence of your chimney’s condition whether you sell in two years or stay for twenty.
