What Our Customers Say
Real reviews from Long Island homeowners who trusted Capstone Chimney with their homes.
“Capstone Chimney rebuilt our chimney from the roofline up after another company said the whole thing needed to come down. They saved us thousands and the work is flawless. Two years later, not a single issue.”
Michael R.

Chimney Rebuilding
“We had smoke pouring into our living room every time we used the fireplace. Capstone diagnosed the problem in 20 minutes — oversized flue — and installed a stainless steel liner. Fireplace works perfectly now. Should have called them years ago.”
Sarah T.

Chimney Sweeping & Inspection
“Our chase top was rusted through and leaking into the walls. Capstone replaced it with stainless steel and repaired the water damage inside the chase. It's been three winters and bone dry. Outstanding work.”
Robert D.

Chase Top Replacement
“Beautiful custom copper cap on our Colonial home. It looks incredible and we haven't had a single raccoon visitor since installation. Worth every penny for the quality and craftsmanship.”
Patricia M.

FAQ
Frequently Asked Questions
Answers to the most common questions from Long Island homeowners about chimney maintenance, repair, and safety.
The National Fire Protection Association recommends annual chimney inspections and cleaning. On Long Island, where many homes rely on fireplaces and wood stoves during harsh winters, yearly sweeping removes dangerous creosote buildup and prevents chimney fires. If you burn more than two cords of wood per season, you may benefit from twice-yearly cleaning.
Common signs include crumbling or missing mortar between bricks, white staining (efflorescence) on the exterior, a leaning chimney stack, water stains on the ceiling near the chimney, rust on the damper, and pieces of tile or brick falling into the firebox. If you notice any of these issues, schedule an inspection before the damage worsens.
Costs vary based on the scope of work. Minor tuckpointing and mortar repair typically ranges from a few hundred dollars, while a full chimney rebuild from the roofline can cost several thousand. We provide free, no-obligation estimates so you know exactly what to expect before any work begins.
A chimney liner protects your home from heat transfer and corrosive flue gases. If your original clay tile liner is cracked, missing, or damaged, a new liner is essential for safety. We install stainless steel liners (most popular for wood and gas appliances), aluminum liners (gas-only), and cast-in-place liners for historic homes. Each option comes with different warranty periods.
A chimney cap is a fitted metal cover that sits on top of your flue opening. It prevents rain, snow, debris, and animals from entering your chimney while also containing sparks. Without a cap, moisture accelerates flue deterioration and animals can nest inside, creating blockages and fire hazards. We offer custom stainless steel and copper caps built to fit your specific chimney.
