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.
Huntington, NY
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.
Garden City, NY
Draft Issues & Chimney Liners
“Professional from start to finish. They swept our chimney, found a cracked liner we didn't know about, and gave us honest options. No pressure, just straight talk. The kind of company you want working on your home.”
James & Linda K.
Massapequa, NY
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.
Smithtown, NY
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.
Oyster Bay, NY
Custom Chimney Caps
“Replaced our broken damper with a damper cap combo. The difference in our heating bills is noticeable — no more cold drafts coming down the chimney. Quick, clean installation. Highly recommend.”
