Famco Chimney Cap Installation: The San Antonio Owner’s Guide

A Famco chimney cap installation in San Antonio typically runs $260 to $540 installed, depending on the cap model, flue size, and roof access. We stock Famco caps and mounting hardware on the truck, so most jobs are done in a single visit. Homeowners usually find us after a Texas storm knocked their old cap loose, or after they spotted rust flakes on the roof and realized the cap had been quietly failing for a couple of seasons.

You already did the hard part: you identified the Famco part you need. What you need now is a straight answer on compatibility, an honest installed price, and a technician who will show up, show ID, and finish the job without inventing problems. That’s the part we can handle.

Which Famco Models This Applies To

Famco makes chimney caps in two broad lines you’re most likely to run into in San Antonio: their standard single-flue caps and their multi-flue or full-coverage caps. The single-flue models (typically the FC and SC series) bolt directly to the flue tile with tension screws. The multi-flue caps mount to the chimney crown with legs and a skirt that covers the entire footprint.

The compatibility gotcha with Famco is the flue measurement, not the cap model number. A Famco cap sized for a 13″ x 13″ flue will not seat correctly on a 13″ x 18″ flue, even if both are “standard” clay tile sizes in San Antonio homes. You want the inside and outside dimensions of your flue before ordering or scheduling. The measurement is stamped on most Famco caps, but sun and rain wear it down fast here. If you can’t read the label, we can identify the right Famco replacement by measuring the flue and the old cap’s mounting footprint on site.

One more thing worth knowing: Famco sells replacement components separately, including spark arrestor mesh and the tension screw sets. If your cap’s stainless body is still sound, you may not need a full replacement. On the OEM-versus-aftermarket question, we default to Famco OEM parts for Famco caps. Aftermarket copies are usually lighter-gauge stainless and their mesh is coarser, which matters here. San Antonio’s chimney swifts and squirrels will test mesh every February through April, and the thinner stuff tears.

Signs Your Famco Chimney Cap Installation Is Failing

• Rust staining on the chimney crown or roof near the flue. This usually means the cap’s mild-steel mounting hardware has corroded, not the stainless cap body itself. The Famco cap is often fine; the bolts are what failed. We replace the hardware and reuse the cap when possible.
• The cap sits crooked or rattles in high wind. Tension screws loosen over years of thermal expansion. A loose cap grinds against the flue tile and can crack it. That’s a bigger repair than the cap itself.
• Debris inside the fireplace or firebox. Leaves, twigs, or nest material mean the mesh has a breach or the cap has shifted off the flue. This is the most common discovery after a San Antonio spring storm with high wind.
• Visible gaps where the cap meets the flue tile. A badly seated cap lets rain run straight down the flue, which accelerates masonry damage. Water mixing with creosote forms an acidic slurry that eats mortar joints.
• Animal sounds from the chimney. If the mesh is intact but the mounting failed, animals push underneath the lifted edge. We see this most often on two-story homes in areas like Alamo Heights and Terrell Hills where roof access isn’t regularly inspected.

Replacement Cost & What’s Included

Here’s what to expect in San Antonio for a Famco chimney cap installation with Alcott:

• Parts: $90 to $250 for the Famco cap itself, depending on size and whether it’s a standard single-flue or a multi-flue model. We use Famco OEM parts unless a specific aftermarket component is demonstrably better for your situation, which we’ll explain in writing before any work begins.
• Labor and roof work: $170 to $290. This includes ladder setup, the install itself, securing the cap to the flue or crown, and a visual inspection of the flue while we’re up there.
• Masonry anchor refresh: $35 to $75 when the old screw holes are stripped or the mortar around the flue has crumbled. This is common on pre-1990 San Antonio homes with original clay tile flues.

Every job includes the 365-Day Done Right Promise. If the cap loosens, shifts, or fails within a full year, we return and make it right at no charge. You also get a written price before any work starts, so the number on the invoice matches the number you approved. No surprises after the fact. Ruben Castellano has been setting Famco caps on San Antonio chimneys for well over a decade, and he will tell you plainly if your existing cap can be saved or if replacement is the smarter money.

DIY or Call Us?

There’s a safe way to be involved in this job, and an unsafe way. The safe version: you can check from ground level whether your cap looks off-center, whether the mesh has visible holes, or whether rust streaks are running down the chimney. That tells us what to bring. The unsafe version involves climbing onto a San Antonio roof with a power drill and trying to set tension screws while balancing on clay tile or a steep pitch. We don’t recommend that. The tools are simple, but the fall risk is not, and a cap that isn’t properly seated will let water through while looking fine from below.

If you’re comfortable on a ladder and want to inspect the cap at eye level without removing it, that’s reasonable. Frustration usually starts when owners discover their flue size doesn’t match the replacement cap they ordered online. That’s exactly the situation our truck stock solves. Call (903) 515-5079 and we’ll bring the right Famco cap, the right hardware, and a trained tech who won’t make you feel foolish for trying.
