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 Waltham: What to Know First
We provide independent Famco chimney repair in Waltham, typically completing most jobs in a single visit with no-hassle upfront pricing. Common repairs run from $340 for targeted mortar repointing to $2,800 for partial rebuilds involving Famco crown assemblies. We are not affiliated with or authorized by Famco - we are an independent Famco service provider - which means we source parts based on what your chimney actually needs, not what a factory manual prescribes.
This page is for Waltham homeowners who have a Famco cap, crown, flashing, or venting component showing wear. You have probably owned your house long enough to know when a contractor is padding a bill. We do not do that. Call (781) 905-8338 and a live person will answer, 24 hours a day.
How Famco Products Fail - and How We Fix Them
- Famco chimney caps (standard and wind-directional series) - fastener corrosion in Waltham’s freeze-thaw cycle. The 304-grade stainless screws Famco uses on standard caps hold up reasonably well, but after eight to ten New England winters the expansion and contraction loosens the mesh-to-frame joints. We see this constantly on the ranch-style homes off Trapelo Road where the cap sits in sustained west wind. We remove the cap, chase-thread the stripped holes, and install 316-grade hardware with neoprene-backed washers. The cap stays put.
- Famco chimney crowns - hairline cracking from thermal shock. Famco’s pre-formed concrete crowns are dimensionally accurate but pour slightly more porous than poured-in-place crowns. In Waltham’s climate, water enters those pores before January, freezes, and opens cracks that reach the flue within two seasons. We do not slap sealant on top and call it done. We grind the crack to a V, inject HeatShield cerfractory foam for structural fill, then top-coat with a vapor-permeable crown sealant. The repair breathes without letting bulk water in.
- Famco base flashing - step-flashing separation at the brick interface. The L-foot base flashing Famco packages with some chimney cap kits works fine on new construction, but on Waltham’s older homes with multiple roof layers the step flashing often ends short of proper overlap. Water runs behind it and rots the sheathing. We remove the compromised flashing, install new copper step flashing woven into the courses, and counter-flash with a custom-bent cap. On steep pitches near Prospect Hill we use a heavier 20-ounce copper that holds its shape during installation.
- Famco B-vent and gas vent terminals - spalling and mortar loss at the penetration. These terminals see less heat than wood-burning flues but more condensation. The constant dampness dissolves the lime in older Waltham mortar, especially in the 1950s capes around the South Side where the original mortar mix was heavy on sand. We tuckpoint with a Type N mortar matched to the existing hardness, never harder than the brick itself. Hard mortar on soft brick is a mistake we see other contractors make regularly.
- Famco wind-directional chimney caps - seized rotation mechanisms. The bearing race in these caps collects creosote and freeze-thaw debris, then seizes solid. A seized wind-directional cap is worse than a standard cap because it blocks draft from certain angles. We disassemble the mechanism, ultrasonic-clean the bearing components, re-lubricate with high-temperature graphite paste, and reassemble. If the race is pitted, we source a replacement from Olympia Chimney or fabricate a matched part. We do not sell you a whole new cap when a $40 bearing fixes the problem.
Our Famco Chimney Repair Process
- 1
Call and scheduling. A live person answers, 24/7. We book a two-hour arrival window. You get a confirmation text with the technician’s name and photo.
- 2
Level-2 camera inspection. Our tech runs a camera the full flue length, photographs the crown, cap, and exterior courses from the roof and the ground. You see the photos on a tablet before we write the estimate.
- 3
Parts decision. We check Famco OEM availability against quality aftermarket alternatives from Olympia Chimney or Copperfield. We explain the trade-off - warranty coverage, lead time, price - and you decide. No default to the most expensive option.
- 4
The repair. Background-checked, uniformed technicians complete most jobs in a single visit. We lay drop cloths, work with the damper closed to keep dust out of your house, and clean the work area with a HEPA vacuum before we leave.
- 5
Testing and documentation. We run a smoke test or draft gauge check, depending on the repair. You get a photo report, the written 90-Day Done Right Promise, and a plain-English summary of what was done and what to watch.
- 6
Follow-up. We call within two weeks to confirm the repair is holding. If something is not right, we come back. In writing, no arguing.

Why Waltham Homeowners Call Hearthstone Chimney Co. for Famco Work
We have been answering the phone with a live person for over 42 years. Russell Haines, our owner, has spent the better part of two decades on Waltham roofs, including plenty of older colonials near the Moody Street corridor where the fireplaces are well-used and the flue liners tell stories. He knows which Famco caps were installed by the same builder in the 1990s and where they tend to fail.
Our 90-Day Done Right Promise is in writing, not a handshake. If it is not right, we make it right. Our technicians are background-checked and uniformed, and they carry DuraFlex, HeatShield, and Gelco materials on the truck alongside Famco-compatible parts. Most jobs finish in one visit. We do not chase trends, we do not upsell, and we do not disappear after the check clears. If the flue is clear and the crown is sound, you will not hear from me until next season. That is the goal.
FAQs
No - Famco’s limited warranty on caps and crowns covers manufacturing defects, not installation or subsequent repair work performed by independent technicians. Using an independent Famco service provider like Hearthstone Chimney Co. does not void what warranty remains, provided we do not modify the product in ways that alter its intended function. We document our work with photos in case a future warranty claim arises. Call (781) 905-8338 if you want us to review your original purchase paperwork.
Most Famco caps and standard flashing components arrive within three to five business days if we order OEM. We stock common sizes of Olympia Chimney and Copperfield equivalents that match Famco dimensions, which lets us complete many repairs same-day. For wind-directional caps or custom powder-coated finishes, OEM is usually worth the wait. We tell you the lead time before you approve the estimate.
Repair is viable when cracks are under one-eighth inch wide, the crown surface is still reasonably level, and the underlying concrete has not delaminated. We make that call with a hammer test and close visual inspection, not guesswork. If the crown sounds hollow when tapped or the steel mesh reinforcement is exposed, replacement is the honest recommendation. Either way, you see the photos and we explain the reasoning before you spend anything.
Often yes. Famco has used consistent dimensions across their standard cap lines for decades. We can replace a damaged mesh section, fabricate a missing lid, or match a wind-directional mechanism to your existing base. When the cap is too corroded to salvage, we source a replacement that matches the footprint so your flashing does not need rework. We do not sell you a full system when a partial fix is sound.
Every year, before burning season. Waltham’s freeze-thaw cycle is hard on masonry and metal alike. A cap that looked fine in September can have a seized bearing or loosened fasteners by March. Our $89 Seasonal Tune-Up includes a Level-1 inspection, cap and crown check, and a condition report. If we find nothing wrong, we tell you so. Call (781) 905-8338 to book - estimates are free.
