We’ve been answering calls from Valley Stream since 1984, and we know the village’s chimneys better than almost anyone. The postwar Cape Cods along Merrick Road, the small Colonials near the Gibson neighborhood, the ranch homes off Mill Road - they all share the same story. Built between 1945 and 1965, originally heated with fuel oil, now pushing seventy or eighty years of service. That history lives in the brick and mortar. We see it in the sulfur-stained flue tiles, the spalling crowns, the corroded caps that barely survived another coastal winter. When you call Hearthstone Chimney Co. at (855) 950-3861, you get a live person, 24 hours a day. Not a voicemail. Not a callback queue. A real voice, and a crew that knows Valley Stream’s housing stock because we’ve worked on hundreds of these exact chimneys.
Why Hearthstone Chimney Co. of New York City Is Valley Stream’s Preferred Chimney Repair Company

If it’s not right, we come back.

Our Chimney Repair Services in Valley Stream
Mortar Repointing
The mortar joints in Valley Stream chimneys take a double beating. Decades of acidic sulfurous flue gases from oil burners weaken the interior masonry, while salt-laden air from Jamaica Bay - barely two miles away - attacks the exterior joints. We’ve repointed chimneys on Hendrickson Avenue where the mortar had turned to sand above the roofline, and on Cochran Place where freeze-thaw cycling had opened gaps wide enough to slide a pencil through. Our crew grinds out the failed joints to proper depth and packs fresh, properly matched mortar that bonds to the original brick. Done right, and we stand behind it.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in Valley Stream’s older housing stock. The combination of oil-soot-weakened mortar and coastal humidity creates perfect conditions for freeze-thaw damage. We see it worst on south- and west-facing exposures, where winter sun melts ice that refreezes overnight. Our Chimney Repair team removes damaged bricks, sources matching replacements when needed, and rebuilds the wall with proper bonding. For surface spalling caught early, we can sometimes stabilize with specialized resurfacing compounds. Either way, you’ll get upfront pricing before we start. The number on the estimate is the number on the invoice.
Chimney Waterproofing
Valley Stream’s proximity to the Atlantic means driving rain and wind-borne salt hit chimneys harder than inland Nassau County. Waterproofing isn’t a luxury here - it’s maintenance that extends the life of your masonry by years. We apply vapor-permeable sealants that let the chimney breathe while blocking water penetration. Critical in a climate where humid summers and wet winters never really let the brick dry out completely.
Flashing Repair
The step flashing where chimney meets roof is a common leak point in Valley Stream, especially on the low-pitch roofs common to 1950s ranches. Salt corrosion accelerates metal fatigue, and the freeze-thaw cycle works the flashing loose from the masonry. We replace failed flashing with professional-grade materials, integrated properly with your roofing system. No caulk-only patches. No shortcuts.
Chimney Rebuilding
Sometimes the damage has gone too far for spot repairs. We’ve rebuilt chimneys in Valley Stream where the upper courses had deteriorated to the point of structural concern, always preserving what sound masonry remains and rebuilding to code with matching brick. For homes with abandoned oil flues, we often rebuild as part of a comprehensive relining project - restoring safety and function together.
Tuckpointing
Where mortar joints have weathered but the brick remains sound, tuckpointing restores the weather seal and appearance without the cost of full repointing. It’s a precision job that matches color and profile, and our technicians have done it on hundreds of Valley Stream homes.

Common Chimney Repair Problems We See in Valley Stream Homes
- Orphaned oil flues after gas conversion. When Valley Stream homeowners upgrade from oil to high-efficiency gas, the old oversized masonry flue is frequently abandoned with no liner or improper relining. We routinely discover these deteriorating chases during cleaning calls - crumbling original tile, no documentation, sometimes leaking combustion gases into walls or attic space. This is not a hypothetical risk. We’ve found it. We’ve fixed it.
- Salt-accelerated mortar erosion. The coastal air from Jamaica Bay carries enough salt to corrode metal caps and accelerate joint deterioration in masonry. Homes within a few blocks of the bay show this damage faster than inland neighbors, but no Valley Stream chimney is fully immune. Annual inspection catches it before rebuild becomes necessary.
- Spalling crowns from freeze-thaw and sulfur exposure. After 65-75 years of oil-burner flue gases, many Valley Stream chimney crowns are saturated with acidic residue. Add humid coastal winters with repeated freeze-thaw cycling, and the concrete or mortar crown cracks, flakes, and fails. Water enters. Damage accelerates. We’ve replaced crowns on homes where the owner thought the roof was leaking - it was the crown all along.
- Combined flue complications. Many Valley Stream homes were built with interior chimneys serving both the oil furnace and a fireplace through separate flues - or sometimes, improperly, through the same flue. When one flue is abandoned or converted, the shared structure suffers uneven stress. Our Level-2 camera inspections document exactly what’s happening inside your flue system, with photos you can see and a plain-English verdict.

FAQs - Chimney Repair in Valley Stream
No. An abandoned, unlined flue in a 1955 Valley Stream home is a documented hazard we encounter regularly. The original tile liner crumbles, the acidic residue from decades of oil burning continues to weaken the masonry, and the oversized flue can leak combustion gases or allow chimney fires to spread to framing. We recently repaired a chimney in the Gibson neighborhood on Colonial Drive where an orphaned flue from a 1950s oil-to-gas conversion had no liner and was leaking hot gases into the attic. Our crew installed a HeatShield ceramic liner to restore safety and prevent a potential house fire. If your conversion left the old flue untouched, call (855) 950-3861 for an inspection - estimates are free.
Salt-laden coastal air accelerates mortar joint erosion and corrodes metal chimney caps, dampers, and flashing faster than inland Nassau County neighbors experience. In Valley Stream, barely two to three miles from Jamaica Bay, we see premature cap failures and flashing rust on chimneys half the age of comparable inland structures. The salt also intensifies freeze-thaw damage by drawing moisture deeper into the masonry. Annual inspection and prompt repair of failing mortar or metal components prevents the accelerated deterioration from becoming a rebuild. Call us for a free inspection - we’ll show you exactly what the salt air has done to your chimney.
In most Valley Stream homes, crown repair or replacement is sufficient if the brick courses below remain sound. We evaluate the structure with a Level-2 camera inspection and physical assessment. If the spalling is limited to the crown and the upper brick shows only surface weathering, we rebuild or seal the crown and address any underlying waterproofing failures. If the sulfur damage from decades of oil burning has penetrated deep into the upper courses, partial rebuild may be the better investment. We’ll give you both options with honest pricing - crown repair typically runs $600-$1,400, partial rebuild $1,800-$3,500 - so you can decide based on your budget and how long you plan to stay in the home. Call (855) 950-3861 for an exact quote.
Yes. The 1945-1965 housing stock in Valley Stream almost universally used clay flue tiles sized for oil-burner flue gas temperatures. After 65-75 years of acidic sulfurous exposure, these tiles are often cracked, shifted, or eroded at the joints - a condition we document on nearly every Level-2 inspection in the village. We do not recommend leaving original tile in service if it shows any deterioration. Our standard repair is a HeatShield ceramic liner or DuraFlex stainless steel liner, properly sized for your current heating appliance and installed to current code. We’ve relined hundreds of these original flues. Call for a free inspection and we’ll show you photos of your liner’s actual condition.
Annually. The combination of salt air, humid coastal winters, and aging oil-burner residue in Valley Stream’s housing stock creates conditions that accelerate deterioration beyond what national averages suggest. An annual Level-2 inspection with camera documentation catches crown cracks, liner failure, and mortar deterioration before they become leaks, structural problems, or safety hazards. We recommend scheduling before the heating season begins - late summer or early fall - when our Valley Stream appointment calendar still has flexibility. Call (855) 950-3861 to schedule; estimates are free.
