How Much Does Chimney Work Cost in Orange County, NY? (2026 Guide)

Chimney work in Orange County runs about on par with the broader Hudson Valley, which is to say it is not cheap. A basic chimney sweep costs $150 to $350. A stainless steel liner installation runs $1,500 to $4,500. Full chimney rebuild above the roofline costs $3,000 to $10,000 or more. The range is wide because chimney projects involve masonry, metalwork, roofing, and sometimes structural framing, and the condition of the existing chimney determines how much work is needed.

Orange County has a lot of chimneys. The county's housing stock spans from 1700s-era stone farmhouses in the western towns to post-war suburban construction in Monroe and Middletown, and nearly every home built before 2000 has at least one chimney. Many of the older homes have two or three, serving fireplaces, furnaces, and water heaters on separate flues. That older housing stock means a steady demand for chimney maintenance and repair.

Two factors make chimney work especially common in Orange County. First, many homes still have wood-burning fireplaces that get regular use. The rural character of the western towns, combined with heating oil prices that push $4 per gallon, keeps firewood popular as a supplemental heat source. A cord of seasoned hardwood costs $250 to $400 in Orange County, and homes that burn 3 to 5 cords per winter need annual chimney sweeps to prevent creosote buildup.

Second, the freeze-thaw cycle in Orange County is brutal on masonry chimneys. The county gets about 60 freeze-thaw cycles per year, where temperatures swing above and below 32 degrees in a single day. Each cycle pushes water into the mortar joints and brick pores, freezes it, and expands it slightly. Over 10 to 20 years, this process cracks mortar, spalls brick faces, and deteriorates the chimney crown. A chimney that looks fine from the ground may have significant mortar damage when inspected from the roof.

Chimney liner installation is one of the most common chimney jobs in Orange County, and it is driven largely by the county's heating fuel mix. Many homes in the western and rural parts of the county still have oil-fired furnaces and boilers. When these systems vent through an unlined masonry chimney, the combustion gases condense on the cool interior walls, and the acidic condensate eats through the mortar joints from the inside out. Over time, this can create gaps in the flue that allow carbon monoxide to seep into the house.

New York State building code requires a chimney liner for any heating appliance. If your home has an older oil furnace venting into an unlined chimney, you need a liner. A stainless steel liner for a furnace or boiler flue costs $1,500 to $3,500 depending on the length and diameter. The liner slides down the existing masonry flue and connects to the appliance at the bottom and a cap at the top. Insulating wrap around the liner adds $300 to $800 to the cost but is recommended for oil-fired appliances to improve draft and reduce condensation.

Wood-burning fireplaces also require liners, and many older Orange County homes have fireplaces with clay tile liners that have cracked or deteriorated. Replacing a cracked clay liner with a stainless steel flex liner costs $2,000 to $4,500 for a typical two-story chimney. The Level 2 camera inspection, which runs $200 to $500, is how the chimney tech determines whether your existing liner is intact or needs replacement.

Homes that convert from oil heat to a heat pump or gas furnace often face a chimney question. If the chimney is no longer needed for venting, it still needs to be capped and waterproofed to prevent water from entering the house through the open flue. Capping and sealing an unused chimney costs $300 to $800. Some homeowners in this situation choose to have the chimney removed above the roofline to eliminate the ongoing maintenance cost, which runs $2,000 to $5,000 depending on the height and complexity.

Chimney work costs are influenced by the age of the housing stock, the prevalence of wood-burning fireplaces, and the heating fuel situation in each part of the county.

Newburgh has some of the oldest and most varied chimneys in Orange County. The historic East End and colonial-era homes along Grand Street and Liberty Street have chimneys that date to the 1800s, with hand-laid brick, multiple flues, and decorative corbeling that adds complexity and cost to any repair. A full tuckpointing job on a large Newburgh chimney runs $1,200 to $3,000 because of the height, the number of courses, and the need to match the original mortar color and joint profile. Partial rebuilds on these chimneys cost $4,000 to $10,000. The newer parts of the City of Newburgh and the surrounding town have more standard chimneys that price in line with county averages. Chimney sweeps in Newburgh run $150 to $300.

Middletown has a large stock of 1950s to 1980s homes, many with oil-fired heating systems that vent through masonry chimneys. Liner installations are a common job in Middletown, particularly when homeowners replace aging oil boilers. A stainless steel liner for a Middletown furnace chimney runs $1,500 to $3,000. The city also has plenty of wood-burning fireplaces that need annual sweeps ($150 to $250). Chimney crown damage from freeze-thaw is common on the post-war houses because many original crowns were poured with basic mortar rather than the more durable mixes used today. Crown repair runs $300 to $800.

Monroe has newer housing on average, and many homes built since the 1990s have factory-built (prefabricated) fireplaces rather than traditional masonry. Prefab fireplaces have their own chimney systems (metal pipes inside a chase) and require different maintenance than masonry chimneys. A sweep on a prefab system runs $150 to $250. The homes in Monroe that do have masonry chimneys are generally in good condition because they are not as old. Tuckpointing needs are less common here. Where Monroe homeowners spend on chimney work is on gas fireplace conversions and cap installations, running $200 to $500 for a cap and $1,500 to $3,500 for a gas insert in an existing fireplace.

Warwick has the highest per-household chimney maintenance spending in the county. The combination of wood-burning fireplaces in active use, oil-heated homes needing liners, and older masonry chimneys exposed to heavy freeze-thaw makes chimney work a regular expense. A chimney sweep in Warwick runs $175 to $350 because travel time is longer for chimney companies based in the eastern part of the county. Many Warwick homes have two chimneys (one for the fireplace, one for the furnace), and annual service for both runs $300 to $600. Full chimney rebuilds on Warwick farmhouses and older colonials cost $5,000 to $12,000. The stone chimneys on the oldest properties require a mason experienced with fieldstone and lime mortar, which is more specialized and more expensive than standard brick work.

Goshen has a solid mix of chimney ages and types. The village center has historic homes with masonry chimneys that need regular tuckpointing and crown maintenance. The surrounding areas have newer homes with standard chimney needs. Chimney sweeps in Goshen run $150 to $300, and liner installations for oil-heated homes cost $1,500 to $3,500. Goshen's central location means chimney companies from across the county serve the area without significant travel surcharges.
