We’ve been sweeping chimneys in Baltimore since 1984. That’s more than 42 years of working in Federal Hill rowhomes with narrow flues, Canton waterfront properties with salt-air corrosion, and the stone masonry chimneys common in Roland Park and Guilford. Russell Haines built Hearthstone Chimney Co. on a straightforward idea: show the homeowner exactly what you found, explain it in plain English, and stand behind the work. No scare tactics, no phantom repairs, no surprises on the bill.

Baltimore’s freeze-thaw cycles are hard on chimneys. Water gets into hairline cracks in the crown, expands when temperatures drop below 20 degrees, and opens gaps that let creosote accumulate faster than in milder climates. We’ve seen flues in Hampden and Remington that hadn’t been swept in a decade, packed with glazed creosote that required rotary cleaning. We’ve also seen chimneys in Locust Point that just needed a basic sweep and a clear verdict that everything was sound. Both homeowners got photos they could see, a written report, and our 90-Day Done Right Promise.

Our technicians are background-checked and uniformed. They arrive with HEPA-filtered vacuums, rotary chains for glazed creosote, and digital cameras for Level 2 inspections. Most jobs finish in one visit. The price we quote is the price on the invoice.

What Our Chimney Cleaning & Sweep Service Includes

Level 1 Inspection

A Level 1 inspection is the visual examination required annually for chimneys in regular use with no changes to the appliance or fuel type. We examine the readily accessible portions of the chimney exterior, interior, and connecting appliances to verify sound structure and freedom from obstructions and combustible deposits. In Baltimore’s older housing stock, particularly in neighborhoods like Patterson Park and Highlandtown, we frequently find deteriorated mortar joints and missing rain caps that would go unnoticed without this baseline check. Our technician documents everything with photos and delivers a plain-English verdict before any work proceeds.

Level 2 Inspection

A Level 2 inspection is mandatory when a property changes hands, after a chimney fire, or when you modify your heating appliance or fuel type. We use a high-resolution camera system to examine the entire flue interior, from firebox to crown, spotting cracks, gaps, and creosote buildup that no visual inspection can reach. In Baltimore’s historic districts, we’ve found separated flue tiles in homes built before 1940 and improper liner connections in converted boiler flues. You receive dated photos of every finding and a written report that satisfies insurance and real estate requirements. No recommendation is made without camera evidence you can see for yourself.

Creosote Removal

Creosote is the tar-like byproduct of burning wood, and it accumulates in three stages, from powdery soot to hard, glazed deposits that can ignite at temperatures above 451 degrees. We match our cleaning method to the creosote stage: wire brushes for Stage 1, rotary chains for Stage 2, and specialized chemical treatment followed by mechanical removal for Stage 3 glazed buildup. Baltimore homeowners who burn seasoned hardwood and sweep annually rarely see Stage 3, but those who burn pine or operate dampers incorrectly often need more intensive service. We show you the before-and-after photos so you understand what was in your flue.

Soot Removal

Soot accumulation reduces draft efficiency and can release carbon monoxide into living spaces when it blocks the flue or coats the smoke chamber. Our soot removal service uses professional-grade HEPA vacuums and polypropylene brushes that won’t damage clay flue tiles or stainless steel liners. In Baltimore’s tighter rowhomes, particularly in Fells Point and Butchers Hill, proper draft is critical because there’s limited makeup air and neighboring chimneys can create competing pressure zones. We test draft before and after cleaning to confirm your system is drawing properly.

Annual Sweep

The National Fire Protection Association Standard 211 recommends annual inspection and sweeping as needed for all chimneys, fireplaces, and vents. Our annual sweep combines a Level 1 inspection with thorough cleaning of the firebox, smoke chamber, and flue, plus a functional test of the damper and cap. We schedule Baltimore customers by neighborhood to minimize travel time and keep appointments punctual. Many homeowners in Roland Park, Guilford, and Homeland book their annual sweep in late summer, before the first cold snap when our calendar fills. The $89 Seasonal Tune-Up covers this service for standard fireplaces during promotional periods.

Fireplace Cleaning

Fireplace cleaning addresses the visible and hidden surfaces that affect both safety and aesthetics: the firebox walls, hearth extension, ash dump, smoke shelf, and damper assembly. We remove ash deposits, bird nests, and debris that can harbor moisture and accelerate masonry deterioration. In Baltimore, where many fireplaces were converted to gas inserts or decorative use, we verify that the original flue is still appropriate for the current appliance and that no abandoned connections create hazards. Our technicians use drop cloths and HEPA containment to protect your flooring and furnishings.

Brands We Service for Chimney Cleaning & Sweep

We work exclusively with professional-grade materials and have direct experience servicing systems built around HeatShield, Gelco, and Olympia Chimney products. HeatShield’s cerfractory sealant is our go-to for resurfacing deteriorated smoke chambers in Baltimore’s older masonry fireplaces, and we’ve applied it in hundreds of homes from Mount Washington to Lauraville. Gelco’s stainless steel caps and chase covers hold up against Chesapeake Bay humidity and winter freeze-thaw better than the builder-grade aluminum versions we replace every spring. Olympia Chimney’s stainless steel liners and components meet the strictest UL listings, and we stock their standard sizes for same-day installation when a liner replacement is necessary.

We’ve also installed and serviced Famco chimney caps and dampers in Baltimore’s historic districts, where custom sizing and copper finishes preserve architectural integrity while meeting modern safety codes. Whether your system was built with these brands or any other make, we can inspect, clean, repair, and restore it. We don’t substitute inferior materials to hit a price point, and we document every component we install with photos and serial numbers for your records.

Signs You Need Chimney Cleaning & Sweep Right Now

• Burning odors when the fireplace is not in use. Creosote absorbs humidity and releases a sharp, acrid smell during warm, damp weather. In Baltimore’s humid summers, this odor often drives homeowners to call us in July or August. The smell indicates significant buildup that will only worsen before burning season.
• Smoke entering the room instead of exiting through the flue. This signals either a blockage, a damaged flue liner, or negative air pressure in a tightly sealed modern home. In Baltimore rowhomes, we’ve traced smoke backup to collapsed clay tiles, squirrel nests, and improper damper operation. It’s a carbon monoxide risk that warrants immediate inspection.
• Visible black, tar-like deposits on the damper or firebox walls. Stage 3 glazed creosote cannot be removed with standard brushing and requires specialized chemical treatment followed by rotary mechanical cleaning. It ignites at lower temperatures than powdery soot and burns intensely once lit. We’ve seen it in chimneys that appeared “fine” from the outside.
• White staining or efflorescence on the exterior masonry. This indicates water penetration, which accelerates during Baltimore’s freeze-thaw cycles and can damage the flue liner from the outside in. The underlying moisture problem often connects to a missing or damaged cap, cracked crown, or deteriorated mortar joints.
• It’s been more than 12 months since your last professional inspection. The NFPA 211 standard exists because creosote accumulation and structural deterioration happen regardless of how clean the fireplace appears. Many Baltimore homeowners are surprised by what we find in chimneys that “looked okay.” Annual verification is the only reliable prevention.

Our Chimney Cleaning & Sweep Process - Step by Step

1. 1
   Schedule and confirm. When you call (410) 849-6273, a live person answers, 24 hours a day. We ask about your fireplace type, fuel, last service date, and any symptoms you’ve noticed. We provide a no-obligation estimate range and schedule a specific arrival window, not an all-day wait.
2. 2
   Arrival and protection. Our background-checked, uniformed technician arrives in a marked vehicle, lays drop cloths from the entry to the fireplace, and sets up HEPA-filtered vacuum containment. We treat your home with the care we’d want in our own.
3. 3
   Inspection and documentation. We begin with a Level 1 or Level 2 inspection as appropriate, using digital photography to record the condition of the firebox, smoke chamber, flue, damper, and exterior components. For Level 2 inspections, our camera system captures the entire flue interior in high resolution.
4. 4
   Cleaning and restoration. Based on findings, we perform the appropriate cleaning method, from standard brushing to rotary chain removal of glazed creosote. We use professional-grade brushes, rods, and vacuums sized to your flue dimensions. If repairs are needed, we explain them with photos and provide upfront pricing before any additional work begins.
5. 5
   Final testing and reporting. We verify proper draft, test damper operation, and confirm all components function correctly. You receive a written report with dated photos, a plain-English summary of findings, and our 90-Day Done Right Promise documentation. Nothing is recommended without evidence you can see.
