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 Repair in Gaithersburg: What to Know First
Famco chimney repair in Gaithersburg typically runs $185 to $950 for most jobs we see, depending on whether you’re dealing with a cap replacement, crown sealing, or a repoint on an older brick stack near Washington Grove or Lakelands. We’re an independent Famco service provider, not an authorized dealer, which means we fix what the camera shows us, not what a warranty booklet wants us to sell you. Most Famco repairs are done in one visit, with a written price in your hand before a single brick is touched. If you own a home with a Famco cap, damper, or flue component and something’s off, call (240) 220-9395. This page is for Gaithersburg homeowners who want to know what’s actually wrong before anyone quotes a number.
How Famco Products Fail - and How We Fix Them
Famco makes solid equipment, but everything wears in Montgomery County weather. Here’s what we actually find on Famco jobs in Gaithersburg, in plain terms:
- Famco multi-flue caps with failed seams. The larger rectangular caps covering two or three flues develop hairline splits at the folded corners after about eight to ten years. Water gets in, runs down the flue, and you get staining on the smoke shelf. We either reseam with high-temp sealant when the metal’s still sound, or replace with a current Famco cap sized to the exact flue tile.
- Famco dampers that won’t seat flush. This is the one we see most in older brick-stack homes near the Rio Washingtonian Center corridor. Years of heat cycling warps the damper plate just enough that it doesn’t close tight, which means conditioned air leaks up the chimney all summer. We can usually re-seat and adjust the frame; if the plate’s warped beyond adjustment, we replace it.
- Famco chimney caps with clogged mesh. The expanded metal screen on Famco caps does its job, until creosote and pollen cake it shut. Draft drops, smoke backs up into the room, and the homeowner assumes the flue’s blocked. It’s the cap, and it’s a twenty-minute fix on most roofs. We clean the mesh and check the flue itself while we’re up there.
- Famco anchor bolts pulling loose from the crown. On taller chimneys, especially the brick stacks in Kentlands and Washingtonian Woods, the crown mortar around the anchor bolts softens over wet winters. The cap starts shifting slightly in the wind. We reset the anchors in fresh crown mortar and re-secure the cap. If the crown itself is spalling, that’s a separate repair we’ll quote at the same visit.
- Famco spark arrestors with pitted screens. In Gaithersburg’s winter freeze-thaw cycles, sparks and moisture slowly eat pinholes into arrestor mesh. It still looks fine from the ground. Up close, you can push a finger through. We replace the arrestor section, and we’ll show you a photo of the holes before we do it.
The camera doesn’t guess. Neither do we. Every one of these failures gets photographed before and after, and you get those photos in your job record.
Our Famco Chimney Repair Process

Here’s how a Famco repair actually goes when you call us in Gaithersburg:
- 1
Call and describe the symptom. You talk to a live person, not a voicemail. We schedule a visit and assign a named tech to your job. You get a text when they’re on the way.
- 2
Camera-scan inspection (NFPA 211 Level 2). The tech runs a camera down your flue and documents everything: liner condition, damper seat, cap integrity, crown cracks. You see the footage.
- 3
Written scope and price. Before any work starts, you get a written price, written scope, and written warranty. Haven Standard Clause 1. No verbal numbers, no ‘call the office later.’
- 4
The repair. We use Famco parts where the original design matters, and quality aftermarket parts where the material is equivalent and the price is better. We’ll tell you which is which and why.
- 5
Documented record. Photos of every stage go into your job file. You get a copy. This has been our default since 2009, and it’s Clause 4 of the Haven Standard.
- 6
365-Day Done Right Promise. If the repair doesn’t hold, we make it right. That’s stamped on every job, no fine print.

Why Gaithersburg Homeowners Call Level Two Chimney Gaithersburg for Famco Work

Most chimney companies look at a Famco cap and see a part number. We look at it and see the specific way Gaithersburg weather is working against it. That matters because the fix isn’t always ‘buy a new cap.’ Sometimes it’s the crown under the cap that’s failing, or the flashing, or the flue tile behind the damper. We find the actual problem and charge you for that, not for a parts replacement that doesn’t address it.
Our techs are background-checked and uniformed. Our license number is on every page. We answer calls 24/7 with a live person. And when a Famco part isn’t the smartest choice, we’re not stuck recommending it. We work with DuraFlex, HeatShield, and Gelco materials through the Haven buying network, which keeps prices honest. 38,000+ chimneys inspected and cleaned since 2009, every one with a written price before work started and a documented record when it was done.
FAQs
No. As an independent Famco service provider, we’re not bound by the manufacturer’s service network rules, and the warranty on Famco components typically covers the part itself. What we repair around it, the crown, the flashing, the mortar, is separate from the warranty and addressing it now prevents the Famco component from being blamed for damage it didn’t cause. Call (240) 220-9395 and we’ll walk you through it.
We keep standard Famco cap and damper sizes in stock for the common configurations on Gaithersburg homes, so most replacements happen same day. Specialty sizes or multi-flue configurations may take a few days. Either way, you’ll know before you commit. Call (240) 220-9395 for an exact answer on your chimney.
Surface rust on a Famco cap can usually be cleaned and resealed, which runs $145 to $285 in Gaithersburg. Rust that has eaten through the metal, which is what we see after ten-plus years of Montgomery County humidity, means replacement. We’ll show you the camera footage and let you make the call.
Most Gaithersburg appointments happen within a few days. If you’re seeing water staining or smell smoke backing up, tell us when you call and we’ll prioritize it. Call (240) 220-9395. A live person answers. That’s how we run it.
A failed cap lets water into the flue, which accelerates liner damage. In Gaithersburg’s freeze-thaw winters, that water freezes and expands inside the flue tile, which leads to spalling and eventually a liner replacement that costs far more than a cap. The cap is the cheap fix. Wait, and the repair scope grows. Get a camera scan and know what you’re working with. Call (240) 220-9395.
