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.

We’ve been working in Mendham long enough to know the difference between a borough-center colonial with one original flue and a five-acre estate off Mountain Avenue running three fireplaces through two different chimney systems. Our Chimney Cleaning & Sweep team treats each house according to what is actually built, not what it looks like from the hearth.
Why Hearthstone Chimney Co. Is Mendham’s Preferred Chimney Cleaning & Sweep Company
Mendham homeowners tend to stay put. They know when a contractor is guessing. We’ve answered the phone with a live person for over 42 years, and our 90-Day Done Right Promise - in writing, no arguing - means if something is not right, we come back. No paperwork shuffle. No “we’ll see what we can do.”
Our technicians are background-checked and uniformed, and most jobs finish in one visit. We use no-hassle upfront pricing: the number on the estimate is the number on the invoice. For Mendham’s multi-chimney estates, that matters. You are not guessing what three flues and a camera inspection will cost. We tell you before we start.
We also know the local conditions. Mendham’s ridge-top and hillside estates catch cold northwest winds that flatter towns do not, and Morris County winters regularly hold below 20°F for weeks. That drives heavy burning from October through March. We have cleared glazed creosote from flues that have not been opened in two seasons, and we have caught factory-built fireplace inserts hiding behind stone facades that previous sweeps assumed were masonry. The difference matters. A rigid brush in a proprietary metal liner ruins it.
Our Chimney Cleaning & Sweep Services in Mendham
Level 1 Inspection
A Level 1 inspection is the standard annual check for a Mendham chimney that has not changed and is performing normally. We examine the readily accessible portions of the appliance and flue, check for obstructions and combustible deposits, and verify basic soundness. For a single working fireplace in a well-maintained borough-center home, this is often sufficient. We document what we find, and if the flue is clean, we sweep it and move on.

Level 2 Inspection
Level 2 is where we do our real work in Mendham. This is the camera inspection - a full visual scan of the interior flue surfaces, the smoke chamber, and the accessible portions of the liner. We recommend it for every home sale, every new homeowner, any chimney fire or lightning strike, and any time the appliance or flue has changed. In Mendham, we also push hard for Level 2 on any estate with multiple chimneys, any 1980s-90s expansion with stone-faced factory-built units, and any home burning self-harvested oak or hickory. You get photos you can see and a plain-English verdict. Nothing is recommended without evidence you can hold in your hand.
On a multi-acre wooded lot off Mendham’s historic borough center, we swept a home with three separate flues: the original hand-laid masonry chimney, plus a stone-faced factory-built unit added in a 1990s expansion. Our tech scoped the masonry side and found heavy second-degree creosote from the owner’s unseasoned property-cut oak, while the prefab liner got a soft-poly sweep and a damper and smoke chamber check instead of a masonry brush. We pulled the glaze down to first-degree, logged the prefab liner’s rated lifespan for the owner’s file, and set the annual sweep on a recurring calendar.

Creosote Removal
Creosote in Mendham is not theoretical. The town’s heavily wooded estate lots mean homeowners harvest their own oak and hickory - frequently before it seasons properly - and burn it across two or three working fireplaces under one roof. That stacks glazed creosote fast. Stage 1 is dusty soot. Stage 2 is crunchy flakes. Stage 3 is the tarry, hardened glaze that chimney fires are made of. We remove it with mechanical whips, poly brushes sized to the flue, and chemical treatments when necessary. For glazed buildup, we do not pretend a standard sweep will do. We tell you what degree we found, show you the photo, and clean it until it is first-degree or gone.

Soot Removal
Soot is the lighter, carbon-heavy residue from efficient burns and gas appliances. Even Mendham homes with gas conversions or inserts produce it, and it restricts draft when it accumulates. We remove it completely, check the flue for proper sizing, and make sure your system is drawing the way it should. For homes near Mendham’s wind-exposed ridges, proper draft is not a luxury. It is what keeps smoke out of your living room on a February night.

Annual Sweep
The National Fire Protection Association recommends annual inspection and cleaning as needed. In Mendham, with active wood-burning culture and multi-flue estates, “as needed” is almost always. We put you on a recurring calendar. You get a reminder before burning season. We show up, scope what needs scoping, sweep what needs sweeping, and log everything for next year. Done right - and we stand behind it.

Fireplace Cleaning
The firebox, smoke shelf, and hearth area collect ash, debris, and deteriorated masonry particles. We clean them thoroughly and check for cracked firebrick, damaged mortar, or rusted components. In Mendham’s older masonry homes, we often find eroded smoke shelves that need repointing or HeatShield treatment. We tell you plainly what can wait and what cannot.

Trusted Brands We Service in Mendham
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and other industry-trusted manufacturers - no builder-grade substitutes.

A DuraFlex liner for a damaged masonry flue. HeatShield cerfractory sealant for eroded smoke chambers. Gelco caps and dampers for proper weather protection on ridge-top chimneys exposed to Mendham’s northwest winds. We do not order parts that leave you waiting two weeks. We carry what we need to finish most jobs in a single visit.
Common Chimney Cleaning & Sweep Problems We See in Mendham Homes
- Factory-built fireplaces mistaken for masonry. Many 1980s-90s Mendham estate expansions added UL-listed prefabricated inserts behind custom stone surrounds indistinguishable from original hand-laid work. Running a rigid masonry brush up a proprietary metal flue liner crimps or tears it, and replacement means matching a discontinued part or replacing the entire unit.
- Multi-flue estates swept incompletely. A house with three fireplaces gets one flue cleaned and two ignored. The owner’s unseasoned property-cut oak keeps burning, and glazed creosote keeps building where no one looked. We count flues before we start, and we clean what we count.
- Uncapped or partially relined flues missed without a camera. Mendham’s aged chimney stock includes flues that have never had proper inspection. Cold northwest winds drive downdraft through damaged or missing caps, pushing smoke into living spaces. A Level 2 camera finds what a flashlight from the top cannot.
- Backdrafting blamed on wind when the flue is the problem. Mendham’s hillside geography does produce genuine wind-induced backdraft, but we verify the flue is clean, properly sized, and unobstructed before we blame the weather. Often it is both, and cleaning improves draft enough to solve it.

FAQs - Chimney Cleaning & Sweep in Mendham
Multiple chimneys do not automatically require Level 2, but in Mendham they usually should get it. The combination of active wood-burning across several flues, estate homes with 1980s-90s expansions, and self-harvested unseasoned oak means we frequently find conditions a Level 1 cannot reveal. We recommend Level 2 at least every five years for multi-flue homes, and immediately for any new purchase, suspected damage, or change in appliance. Call (908) 589-8342 to discuss your setup - estimates are free.
You probably cannot tell from the living room. The stone surround was chosen to match the original masonry, and it does. Our technicians identify factory-built units by the metal firebox visible from the inside, the UL listing plate (usually inside the firebox or on the unit’s side), and the proprietary metal flue liner extending upward. We check this before any brush goes up the flue. If it is factory-built, it gets a soft-poly sweep and a damper and smoke chamber check, not masonry tools. Call (908) 589-8342 and we will sort it out during inspection.
It is almost certainly unseasoned firewood. Mendham’s wooded lots make it easy to cut oak and hickory on your own property and burn it within months. Proper seasoning takes 12-18 months. Green or partially dried hardwood smolders, producing more smoke and cooler flue temperatures. That combination deposits Stage 2 and Stage 3 creosote rapidly, especially when you are running two or three fireplaces. We can remove what is there and tell you what degree it reached. For the future, a moisture meter is cheap insurance. Call (908) 589-8342 to schedule - estimates are free.
Sometimes. Mendham’s ridge-top and hillside estates do catch genuine downdraft from northwest winds, but a dirty or obstructed flue makes any backdrafting worse. We verify the flue is clean, properly sized, and unobstructed first. If cleaning and proper damper operation do not solve it, we may recommend a chimney cap with wind-directed draft or other mechanical solution. We do not sell you what you do not need. Call (908) 589-8342 and we will diagnose it properly.
Yes. The NFPA recommends annual inspection regardless of use, and in Mendham there are specific reasons. Unused flues attract moisture, which degrades liners and mortar. Animals nest in uncapped chimneys. And “barely used” often means occasional holiday fires with unseasoned wood - enough to deposit creosote, not enough to heat the flue and burn it off. We inspect, document, and clean only what needs cleaning. Call (908) 589-8342 to schedule - estimates are free.
