Our Chimney Repair Services in Horsham
Chimney Relining
This is the repair we perform most often in Horsham, and for a specific reason. Your 1960s or 1970s split-level was built with a clay tile liner sized for the oil-burning boiler or furnace that originally heated the house. When that system was later converted to gas - as happened across Montgomery County during the 1980s and 1990s - the flue became badly mismatched. A high-output oil burner needs a large flue to vent properly. A modern 80% or 90% AFUE gas unit produces lower temperatures and much less draft. The result: an oversized flue that cannot warm up quickly, heavy condensation on the tile surfaces, and accelerated creosote buildup that spalls and cracks the liner from the inside out.
We repaired a clay tile liner in a colonial on Babylon Road where the original 8-inch flue from an oil burner was serving a 90% AFUE gas furnace. The oversized flue caused heavy condensation, spalled tiles, and poor draft; we installed a 6-inch DuraFlex stainless steel liner to match the gas unit’s output. The homeowner had lived with smoky fireplaces and a faint sulfur odor for three winters before calling. A proper liner fixed it in one day. Relining a Horsham chimney with stainless steel typically runs $2,200-$3,800 depending on flue height, number of appliances served, and whether the clay tiles must be removed first.
Mortar Repointing
Horsham’s freeze-thaw cycle is hard on mortar joints. Water enters the smallest crack in autumn, expands when it freezes in January, and opens the joint wider by March. Original mortar on a 1970s colonial was never designed to survive fifty years of this. We grind out the deteriorated joints to proper depth and repoint with color-matched, professional-grade mortar formulated for Pennsylvania’s climate. Repointing on a typical Horsham chimney runs $1,200-$2,400. We document the before condition with photos and show you the match before we finish.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is common in Horsham’s older neighborhoods where water has entered through failed crowns or deteriorated mortar and then frozen repeatedly. Once the brick face pops off, the structural integrity of the chimney is compromised. We remove spalled bricks, match replacements from reputable suppliers, and rebuild the affected courses with proper bonding. Partial spalling repair on a Horsham chimney typically costs $800-$1,800. If spalling has progressed to multiple courses or the chimney has begun to lean, a partial rebuild may be necessary.
Chimney Waterproofing
After we repair the masonry, we strongly recommend waterproofing for Horsham homes. The township’s late-winter ice events and humid continental climate mean your chimney absorbs more moisture than structures in drier regions. We apply professional-grade, vapor-permeable sealers from Gelco and Copperfield that allow the masonry to breathe while repelling liquid water. Waterproofing a typical Horsham chimney runs $450-$850 and extends the life of repointing and rebuild work by years. It is not a substitute for fixing the underlying problem, but it is essential protection once the repair is done.

Common Chimney Repair Problems We See in Horsham Homes
- Clay tile liners crack from freeze-thaw cycles after decades of hidden moisture from flue-size mismatch. The oil-to-gas conversion that seemed straightforward twenty years ago left your flue silently deteriorating. By the time you notice draft problems or smell smoke, the damage is extensive. Our camera inspection finds it early.
- Original mortar crowns on 1960s split-levels fail during late-winter ice events, allowing water into the masonry and accelerating spalling. A cracked crown is not a cosmetic issue. Water entering through the crown saturates the brick below, and the next freeze cycle starts the spalling process. We rebuild crowns with proper slope and overhang, or install Gelco pre-formed crowns where appropriate.
- Homeowners ignore draft issues for years until a routine sweep reveals extensive liner deterioration from neglected condensation damage. Poor draft, cold air falling down the flue, moisture stains on the firebox - these are symptoms of a liner that has been failing for seasons. The longer you wait, the more expensive the repair becomes.
- Flashing separation at the roofline lets water into attic spaces and wall cavities, often mistaken for a roof leak. On Horsham’s older colonials, the original step flashing has worked loose after decades of thermal cycling. We repair or replace chimney flashing with proper counter-flashing integration, sealed with professional-grade materials.

FAQs - Chimney Repair in Horsham
The clay tile liner in your Horsham home was sized for the high-temperature, high-draft output of an oil-burning furnace. When you switched to a modern gas unit with lower BTU output and cooler exhaust, the flue became too large to warm up quickly. Exhaust lingers, cools further, and condenses on the tile surfaces. That moisture mixes with combustion byproducts to form acidic condensate that attacks the clay from the inside. We see this pattern constantly in Horsham’s 1960s-1980s subdivisions. The fix is a properly sized stainless steel liner, typically 5 or 6 inches for residential gas appliances. Call (866) 580-4069 and we’ll measure your flue and appliance output to specify the right liner.
You need relining if the camera inspection shows cracked, spalled, or missing clay tiles; if you have persistent draft problems or smoke spillage; or if your appliance was converted from oil to gas without resizing the flue. A simple mortar repair addresses the masonry shell but cannot fix a deteriorated liner. Our Level-2 inspection gives you photos and a plain-English verdict so you can decide with certainty. Estimates are free - call (866) 580-4069 to schedule.
Most 1970s Horsham split-levels need repointing and crown repair rather than full rebuild if the structural brick is sound. We evaluate three things: whether the chimney plumb is true, how deep the spalling has penetrated, and whether the interior liner damage has compromised the wythes. Partial rebuilds address the top courses and crown; full rebuilds are reserved for chimneys that have leaned, settled, or suffered catastrophic liner collapse that cracked the surrounding masonry. Our inspection separates cosmetic concerns from structural ones. Call for a free evaluation.
Clay tile liners in Horsham’s climate typically last 40 to 60 years if the flue was properly sized for the appliance and the chimney was maintained. The problem in Horsham is that many liners have been mismatched to converted gas appliances for decades, accelerating deterioration through condensation damage. A liner that should have lasted until 2020 may have failed silently in 2005. If your home was built between 1960 and 1985 and has never been relined, assume the liner is at or past end-of-life. Our camera inspection confirms the actual condition.
Yes. Horsham’s humid continental climate, frequent freeze-thaw cycles, and late-winter ice events make waterproofing essential protection for repaired masonry. We apply vapor-permeable sealers from Gelco or Copperfield that allow the brick to breathe while blocking liquid water penetration. Waterproofing is not a substitute for fixing failed mortar or cracked crowns, but it significantly extends the life of the repair work. The cost is modest compared to repeating the masonry repair in five years because water was allowed back in. We can include waterproofing in your repair estimate or return seasonally to apply it.
