We’ve been driving to Horsham since 1984. We know the difference between a 1972 split-level off Norristown Road and a 1965 colonial near the old Willow Grove Naval Air Station housing. That matters because your chimney was built for a different fuel, a different appliance, and a different era than the one it’s serving now. Horsham’s homes weren’t designed for the heating systems they run today, and that mismatch shows up in flues we inspect every week.
Our Chimney Cleaning & Sweep team covers all of ZIP 19044, from the established subdivisions near Horsham Township Community Park to the older colonials along Easton Road. We don’t subcontract. We don’t send a salesman. We send a background-checked, uniformed technician with a rotary sweep system and a camera rig that lets you see what we see.

Our Chimney Cleaning & Sweep Services in Horsham
Level 1 Inspection
A Level 1 inspection is the baseline for any Horsham home that hasn’t changed its heating system or experienced a chimney fire. We examine the readily accessible portions of your chimney exterior, interior, and appliance connection. For the typical Horsham colonial with an original masonry fireplace, this catches obvious creosote buildup, bird nesting, and crown deterioration before they become expensive problems. We recommend this annually for homes still burning wood or pellets in the original fireplace.

Level 2 Inspection - Critical for Horsham’s Oil-to-Gas Conversions
Level 2 inspection is where we spend most of our time in Horsham, and for good reason. This is the camera inspection that examines the entire flue interior, attic clearances, and appliance connection points. It’s required by NFPA 211 whenever a fuel type changes, a flue liner is added, or a new appliance is installed. In Horsham, that describes a significant share of the housing stock.
Horsham’s 1960s-1980s tract homes frequently have multi-flue masonry chimneys originally lined for oil furnaces, but many were converted to gas heat, creating a flue size mismatch that causes poor draft, excess moisture, and accelerated creosote buildup unique to this suburb. The original clay tile liner, sized for the high temperatures and volume of oil combustion, is now far too large for the lower-BTU output of a modern 80% or 90% AFUE gas unit. Hot flue gases cool too quickly, condensation forms on the liner walls, and that moisture dissolves creosote into acidic compounds that eat mortar joints from the inside out.
We document this with photos. You see the spalled tile, the glazed creosote, the water streaks. Then we explain your options in plain English.

Creosote Removal
Creosote in Horsham chimneys isn’t just a wood-burning problem. The oil-to-gas conversion legacy has created a secondary creosote pattern we see regularly: condensed hydrocarbons from incomplete combustion mixing with moisture in an oversized flue, forming a tar-like deposit that standard brushing won’t touch. We use rotary sweep systems with chains and whips matched to your flue diameter, plus chemical treatments for glazed creosote that has hardened to Level 3. In a split-level on Norristown Road, we pulled a four-inch layer of creosote from a clay tile flue that had been downsized for a 90% AFUE gas boiler. The original oil-sized liner was letting hot flue gases condense inside, eating through the mortar. We relined with a DuraFlex stainless insert, matching the new appliance’s output for safe draft.

Soot Removal and Fireplace Cleaning
Soot removal addresses the fine carbon residue that coats fireboxes, smoke shelves, and damper assemblies. In Horsham homes where the fireplace has been used as a decorative feature for years, accumulated soot can restrict airflow and create odors when humidity rises in summer. We clean the full firebox, remove the damper for hand-cleaning if accessible, and vacuum the smoke chamber. For homes near Horsham’s wooded areas - particularly those backing onto parkland or the township’s greenbelt corridors - we also check for leaf debris and animal nesting that can block the flue.

Annual Sweep
An annual sweep is the single best investment for any Horsham homeowner with a functioning fireplace or solid-fuel appliance. We schedule these heavily in late summer and early fall before heating season begins, but we also see a spring spike as homeowners discover frost-heaved crowns and spalled liners once heating season ends. Horsham sits in a humid continental zone with cold winters, frequent freeze-thaw cycles, and significant late-winter ice events that accelerate mortar joint deterioration and tile liner cracking in the aging masonry chimneys that are widespread here. Booking your annual sweep in August or September locks in your preferred date. Waiting until October often means a two-week wait.

Trusted Brands We Service in Horsham
We don’t guess at parts. Our trucks stock components from Olympia Chimney, Famco, and DuraFlex - the brands we specify for our own relining and repair work - so most Horsham jobs don’t wait on a warehouse order. DuraFlex stainless liners handle the flue-gas condensation problems we see in converted split-levels. Famco caps and dampers seal out the driving rain and snow that accelerate deterioration in Horsham’s older masonry. Olympia Chimney’s components meet the sizing requirements for modern high-efficiency appliances. When we recommend a repair, we can usually complete it that day because the right part is on the truck.
Common Chimney Cleaning & Sweep Problems We See in Horsham Homes
- Cracked clay tile liners from decades of freeze-thaw cycling. Horsham’s clay tile liners are now 40-60 years old. Cold winters, frequent freeze-thaw cycles, and significant late-winter ice events have taken their toll. We discover cracked or spalled sections on routine video inspection in older colonials throughout the township’s established subdivisions. These cracks allow flue gases to seep into wall cavities.
- Deteriorated mortar joints from ice damage. Water enters hairline cracks in summer, freezes and expands in winter, and opens gaps that let flue gases leak into adjacent living spaces. We find this in the upper courses of Horsham chimneys most often, where the crown has cracked and allowed water penetration.
- Flue size mismatch after oil-to-gas conversions. Technicians working Horsham’s older split-levels regularly find that a chimney originally lined and sized for a fuel-oil furnace is now venting a modern 80% or 90% AFUE gas unit. The flue is far too large, condensation builds up heavily, and the liner has often been quietly deteriorating for years before the homeowner calls for a routine sweep.
- Heavy creosote accumulation in oversized flues. The combination of lower flue gas temperatures and excessive flue volume creates ideal conditions for creosote condensation. Homeowners who switched to gas ten or fifteen years ago and never had the flue evaluated are often surprised by what the camera reveals.

FAQs - Chimney Cleaning & Sweep in Horsham
The flue liner was sized for your old oil furnace’s higher output and hotter flue gases, and it’s now too large for your gas unit’s lower-BTU, cooler exhaust. The gases cool before they exit, water vapor condenses on the liner walls, and that moisture mixes with combustion residue to form acidic compounds that deteriorate mortar. A Level 2 camera inspection will confirm the condition of your liner, and we can quote a properly sized stainless insert if needed. Call (866) 580-4069 - estimates are free.
The National Fire Protection Association recommends annual inspection for all chimneys, regardless of use frequency. In Horsham, we also urge annual service because your chimney likely vents a heating appliance that runs daily all winter, not just the fireplace. That appliance produces its own combustion residue and condensation, especially in oversized flues. Even light fireplace use adds creosote that can ignite if accumulated over multiple seasons.
A Level 2 inspection is a camera examination of the full flue interior, plus accessible portions in attics and basements, documented with photos. Your Horsham home needs one if you’ve changed fuels, installed a new appliance, experienced a chimney fire, or are buying or selling the property. Given the prevalence of oil-to-gas conversions in Horsham’s 1960s-1980s housing stock, we recommend Level 2 for any home where the heating system was converted without a documented flue evaluation.
We can sweep it, but we won’t recommend continued use without repair. Cracked clay tile liners allow flue gases, including carbon monoxide, to escape into wall cavities or living spaces. In Horsham’s older colonials with original liners now 40-60 years old, we regularly find cracks that the homeowner never suspected. We document them with camera photos, explain the hazard in plain English, and provide options ranging from stainless steel relining to full reconstruction depending on severity.
Yes. This is among the most common work we perform in Horsham. We evaluate the existing flue, measure the new appliance’s output requirements, and specify a properly sized liner - typically a DuraFlex stainless insert - that corrects the draft and condensation problems the conversion created. Most of these jobs are completed in a single visit once materials are on hand. We’ll be there when we say.
