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.

Why Top Hat Chimney Is Medfield’s Preferred Fireplace Services Company
Wendell Pike started this company in 1999 and still puts his name on every job that goes through Medfield. That matters in a town where people talk. Ask anyone on your street. The local reputation is built on showing up when promised, telling homeowners when a fireplace does not need work, and backing the whole thing with the 90-Day Done Right Promise in writing: if it’s not done right, one call brings the crew back at no cost.
We’re not a franchise that swapped in a crew from another county. The sweep who shows up at your door lives in the same Massachusetts weather you do, understands what the Charles River fog does to flashing and crowns, and knows the difference between a 200-year-old rubble-core chimney and a 1980s builder-grade prefab. Our calls are answered by a live person around the clock. And every technician is background-checked, uniformed, and gives you a real arrival window, not a four-hour “sometime Tuesday.”
For Medfield homeowners between 50 and 70 who have been burned by a national chain’s bait-and-switch pricing, the difference is simple: the number you hear on the phone is the number on the invoice. No surprise charges at the door. No pressure to replace a liner that has years left.
Our Fireplace Services in Medfield
Fireplace work in Medfield splits into two worlds. The old town-center homes have wide, unlined masonry chimneys that predate modern codes. The subdivisions built in the 1960s through 1980s, along the river and off Route 109, have factory-built fireplaces with metal components that rust and warp. We work both. Here is what that looks like.
Gas Fireplace Service
Gas fireplaces in Medfield get used hard through the winter, then ignored. By fall, we routinely find dirty burner tubes, clogged pilot assemblies, and thermocouples that have worn out from thousands of heat cycles. A gas fireplace that has not been serviced in a few years may still light, but it is likely burning inefficiently and possibly venting poorly. In Medfield’s river-adjacent neighborhoods, moisture makes venting problems worse because rust builds inside the flue. We clean, test, and adjust gas fireplaces and gas inserts so they light reliably and vent safely. If a part is shot, we’ll quote the replacement before touching a screwdriver.

Wood Burning Fireplace
Wood-burning fireplaces in Medfield’s older homes often have original fireboxes with cracked brick and deteriorating mortar. The newer colonials have prefab metal fireboxes with refractory panels that crack from freeze-thaw cycling. We inspect both the same way: camera down the flue, visual check of the firebox, smoke test if needed. From there we’ll tell you whether it’s a simple sweep, a firebox repair, or a liner issue. No scary talk, no invented urgency. If the fireplace can wait, we’ll say so.

Fireplace Insert
Inserts are popular in Medfield because they turn a drafty old fireplace into real heat. But the installation matters more than the unit. In older Medfield homes, especially in the town center, we often find the original chimney has no liner at all, just bare brick exposed to the flue. That becomes a mandatory relining conversation before any gas or wood insert goes in. We install and service inserts with proper liners and correct clearance, so the heat stays in the house and the exhaust goes up and out. We work with trusted brands including Copperfield and Famco.

Damper Repair
A damper that won’t close lets heated air pour up the chimney all winter. In Medfield’s older colonials, we see throat dampers rusted open or warped from decades of heat. In factory-built fireplaces, the damper is a metal component that deforms with temperature swings. We repair or replace dampers, and we’ll check the whole firebox while we’re in there. Often the damper is the visible symptom of a deeper flue problem, and the camera shows us what’s really going on.

Trusted Brands We Service in Medfield
We install and service parts from Gelco, Olympia Chimney, and Copperfield, plus several other manufacturers we’ve come to trust over the years. When a Medfield fireplace needs a manufacturer-specific part, we can often have it on hand faster than a big-box store special order. That means less downtime between the diagnosis and the fix. Whether it’s a Gelco chase cap for a rusted prefab chase off Pound Street or an Olympia damper assembly for a 1980s colonial, we stock or source parts that match the original spec, not a universal approximation.
Common Fireplace Services Problems We See in Medfield Homes
Every town has its own failure patterns. Here is what we see most in Medfield, drawn from real service calls:
- Rusted prefab chase caps and flashing. The Charles River runs directly through Medfield, and the ground fog and prolonged moisture in the low-lying corridor accelerate rust on metal chimney components. Homes along the river tend to show crown and flashing deterioration roughly a decade ahead of upland towns like Sherborn.
- Cracked clay flue liners in 40-to-50-year-old colonials. The builder-grade fireplaces installed in Medfield’s 1960s-1980s subdivisions are all reaching the point where clay tile liners crack and spall. Hairline cracks are normal to a degree, but once they open up, flue gases can reach the surrounding structure.
- Unlined rubble-core chimneys in historic town-center homes. Homes dating to the 1700s and early 1800s often have wide, multi-flue chimneys built without any liner whatsoever. If you’re switching from oil to gas or adding an insert, you’ll need a liner installed before the appliance can pass code.
- Cracked refractory panels and warped dampers in factory-built fireplaces. Even a rarely used prefab fireplace in Medfield goes through freeze-thaw cycles every winter. The metal components expand and contract, and after 20 to 30 years the refractory panels crack and the damper stops seating properly.

FAQs - Fireplace Services in Medfield
An inspection is the only way to know whether the flue liner is still intact and the firebox is sound, because the failure points in a 40-year-old Medfield colonial are hidden behind brick or inside a factory-built chase. We regularly find cracked clay tile liners, spalling firebox bricks, and rusted dampers in these homes even when the fireplace has been used lightly. The camera footage and a plain-English verdict, every time, no exceptions. Call (781) 378-5846 to schedule one before your first fire.

Yes, and it’s worse in the river corridor than on higher ground. The Charles River runs through Medfield, and the elevated ground fog and prolonged moisture exposure along its low-lying neighborhoods accelerate mortar joint erosion and flashing failure. Homes near the river sometimes show crown deterioration a full decade before equivalent homes up in Sherborn. The fix is usually a crown repair or replacement, plus new flashing, and the sooner you catch it the less water has worked into the structure. Call (781) 378-5846 for a quote.

It is. Historic homes in Medfield center often have original unlined rubble-core chimneys, just bare brick exposed to the flue. Code requires a properly sized stainless liner before any gas appliance or insert can be safely vented through that chimney. We install DuraFlex liners and will size the liner to the appliance, not the other way around. Call (781) 378-5846 and we’ll inspect what you have before you commit to the conversion.

In nearly all cases, the parts can be replaced without replacing the fireplace. The rusted cap is usually a Gelco or similar manufacturer-specific chase cap, and the damper is a replaceable component. The bigger question is what the rust and warping tell us about the condition of the rest of the system, and that’s what the camera inspection answers. Call (781) 378-5846 and we’ll give you a parts quote, not a replacement pitch.

Summer fireplace odor is almost always moisture meeting creosote residue. In Medfield, the river valley humidity and summer ground fog make it worse. The moisture reactivates creosote inside the flue, and the smell backs down into the house on hot days. A thorough sweep removes the creosote, and in some cases a damper adjustment or top-sealing damper solves the airflow issue that makes the smell persistent. Call (781) 378-5846 if you’re smelling it in August, because that tells us something about the flue before burning season even starts.
