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 Repair in Leesburg: What to Know First
We provide independent Famco chimney repair in Leesburg, and most jobs are completed in a single visit with no-hassle upfront pricing agreed before we start. A typical Famco mortar repointing or flashing repair runs $280-$620, and we’ll show you camera photos of the damage so you understand exactly what you’re paying for. This page is for homeowners in Leesburg who own a Famco chimney cap, damper, or venting component and need straight answers about what’s failing, what it costs, and who can fix it without voiding whatever warranty remains. Call (571) 701-7519 - a live person answers, 24 hours a day.
How Famco Products Fail - and How We Fix Them
- Famco chimney caps (WC and SC series) - fastener corrosion in Leesburg’s freeze-thaw cycles. The 304 stainless screws on WC-series caps installed before 2018 were underspecified for Northern Virginia’s 25-30 annual freeze-thaw cycles. We’ve pulled dozens off Leesburg roofs where the screw heads have sheared clean, leaving the cap loose and letting water sheet down the flue. We replace with 316 stainless hardware and bedding in a high-flex sealant rated for the temperature swing.
- Famco top-sealing dampers (Lymance and Lock-Top lines) - cable fraying from creosote abrasion. The Lymance cable runs through a narrow guide tube that cakes with glazed creosote in fireplaces burned daily November through March. Once the cable frays, the damper won’t seal fully and you’re bleeding heat up the flue. We remove the assembly, clean the guide tube with a rotary flail, and replace the cable with OEM-spec 7×19 strand - or upgrade to a Gelco cable kit if the homeowner wants a heavier-duty replacement.
- Famco wall vents and exhaust caps - UV-degraded polymer collars on south-facing exposures. The polymer termination collars on Famco’s sidewall exhaust products chalk and crack after six to eight years on Leesburg homes with unshaded southern exposure. Water wicks behind the collar and rots the sheathing before the homeowner smells anything wrong. We cut back to sound substrate, flash with copper or painted steel to match, and seal with a UV-stable silicone that won’t harden in two seasons.
- Famco chimney pots (Terracotta and Cast Aluminum lines) - spalling from absorbed moisture. The terracotta pots are porous, and Leesburg’s driving rains followed by hard freezes pop the face off in layers. Cast aluminum pots fare better but the powder coat fails at the rim, letting oxidation creep under the finish. We can rebuild a terracotta pot with a color-matched refractory patch if the shell is sound, or replace with a Copperfield cast unit that carries a 20-year finish warranty.
- Famco masonry chimney crowns - inadequate overhang and drip edge from original construction. Famco didn’t manufacture the crown, but their venting products are often paired with builder-grade crowns that slope toward the flue instead of away. In Leesburg’s clay-heavy soils, that slight reverse pitch channels water straight to the flue gap. We form and pour a new crown with proper 2-inch overhang and a tooled drip edge, or apply HeatShield CrownSeal if the concrete body is sound but the surface is cracked.
Our Famco Chimney Repair Process
- 1
Call and schedule. A live person answers, asks what you’re burning and how often, and books a Level-2 inspection. Russell Haines has a standing offer: tell me what you are burning and how often, and I can tell you what your chimney looks like before I even climb up.
- 2
Camera inspection and documentation. Our technician runs a 360-degree camera the full flue length and photographs the exterior from the roof and ground. You get the photos and a plain-English verdict - no jargon, no padded findings.
- 3
Parts decision: OEM Famco or quality equivalent. If your Famco component is under warranty, we source OEM. If not, we may recommend DuraFlex, HeatShield, or Gelco equivalents that match or exceed spec - always with your approval and never without explaining the trade-off.
- 4
The repair, done right. Background-checked, uniformed technicians complete most Famco repairs in one visit. Mortar is mixed to Type N or Type O spec matched to the original. Flashing is step-flashed and counter-flashed, not caulked over.
- 5
Post-repair test and photo record. We run a smoke test or draft test to confirm function, then photograph the finished work for your file.
- 6
Written guarantee, no arguing. Every Famco repair is covered by our 90-Day Done Right Promise - Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we make it right. In writing. No paperwork to find.

Why Leesburg Homeowners Call Hearthstone Chimney Co. for Famco Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be here in thirty more. That changes how you treat a customer.
Our 90-Day Done Right Promise means if a Famco flashing we installed lets water in, we come back. No arguing, no hunting for paperwork. Our technicians are background-checked, uniformed, and trained on Famco’s product lines plus the full ecosystem - DuraFlex for liner work, HeatShield for resurfacing, Gelco for damper upgrades. When a Famco part is discontinued or back-ordered, we have alternatives that fit and perform, and we explain the choice so you can decide.
Russell Haines has spent the better part of two decades on Leesburg roofs, including the older colonials near Morven Park where chimneys work hard every winter. He knows which Famco caps were spec’d with the wrong fasteners and which damper cables tend to fray first. That kind of specific knowledge is what lets us quote accurately and finish in one visit.
FAQs
No, if the work is done by a qualified technician using correct parts and methods. As an independent Famco service provider, we use OEM hardware when warranty coverage still applies and document the repair with photos. If your cap is past warranty, we may recommend a Gelco or Copperfield equivalent with a longer corrosion guarantee. Call (571) 701-7519 and we’ll check your install date against Famco’s coverage terms.
Most Lymance or Lock-Top cable replacements are completed in 90 minutes to two hours, including full guide tube cleaning and post-repair function testing. If the damper frame itself is corroded or the flue needs sweeping first, add an hour. We complete most Famco repairs in a single visit. Call for scheduling - estimates are free.
Rebuild only when the masonry shell has lost structural integrity - widespread spalling through multiple wythes, shifted courses, or a tilting top. Most Famco venting issues we see in Leesburg are repairable: cap re-securing, crown sealing, repointing localized mortar failure. We’ll show you the camera evidence and tell you straight which category you’re in. Call (571) 701-7519 for an honest assessment.
Many Famco components remain in production, though some older damper and vent lines have been superseded. We stock common Famco hardware and can cross-reference discontinued parts to DuraFlex, HeatShield, or Gelco equivalents that fit without modification. If we need to order a specific Famco OEM part, we’ll tell you lead time upfront before you commit. Call for availability on your model.
A loose cap or cracked crown lets water into the flue and firebox, which in Leesburg’s hard-freeze winters accelerates mortar deterioration and can damage the flue liner. A stuck-open damper wastes 20-30% of your heating dollars. These are fixable problems that become expensive problems, but they rarely become emergencies overnight. We’ll tell you honestly what can wait until spring and what should be handled before the next burn season. Call (571) 701-7519 for a free inspection and straight timeline.
