What Nassau County Customers Say
J Gorman.
Oceanside, NY • December 2025
“He was true to his word on everything we discussed prior to his doing the job. He did an excellent job at a very reasonable price. We would definitely recommend DME Maintenance to our friends and neighbors.”
★★★★★Michael Torres.
Levittown, NY • October 2025
“Douglas came out same week, found a cracked flue liner we had no idea about. Installed a stainless steel liner, cleaned up completely, and explained everything. Pricing was fair and exactly what he quoted. This is the only chimney company I'll call.”
★★★★★Patricia M.
Massapequa, NY • September 2025
“Used DME Maintenance for an oil-to-gas conversion liner. No hidden charges, no surprises.”
★★★★★R Kelly.
Rockville Centre, NY • July 2025
“Had a blockage in my chimney — birds built a nest. Called DME Maintenance, they came out same day, removed the nest completely, installed a cap, and did a full cleaning. Fast, professional, fair price. Highly recommend.”
★★★★★Linda S.
Garden City, NY • June 2025
“My chimney was leaking every time it rained. DME Maintenance diagnosed it as a failed crown — repaired it the next week, then applied ChimSaver waterproofing. No leaks since. They also noticed my flashing needed attention and fixed that too. Thorough, honest work.”
★★★★★Frank DeLuca.
Merrick, NY • April 2025
“Annual chimney cleaning for three years running with DME Maintenance. Always on time, always thorough, always leaves the place cleaner than they found it. The written report after each visit is a nice touch — my insurance company actually asked for one and I had it.”
★★★★★Susan B.
Valley Stream, NY • February 2025
“I called three chimney companies for estimates on chimney pointing. Two gave me vague quotes over the phone. Douglas came out, inspected the full chimney, showed me exactly which joints were failing, and gave me an estimate on the spot. I chose DME Maintenance — work was excellent and done in one day.”
★★★★★Tom Hatten.
Freeport, NY • January 2026
“Had a pellet stove that kept shutting down. DME Maintenance came out, cleaned the exhaust vent and combustion chamber, and it's been running perfectly ever since. Turns out it was just clogged — saved me from buying a new stove. Very knowledgeable.”
★★★★★Carol Ahen.
Great Neck, NY • November 2025
“DME Maintenance has serviced our chimney for years. When we converted from oil to gas, they handled the liner installation and made sure we had all the paperwork the building department needed. Owner-operated means you're dealing with the same person every time — that matters.”
★★★★★Jim Hempworth.
Plainview, NY • August 2025
“Bought a house with an old fireplace and didn't know the condition of the chimney. DME Maintenance did a full inspection, found a cracked tile in the liner, and walked me through my options without any pressure. Ended up with a new stainless liner — the right call for the age of the house.”
★★★★★Niamh O'Connor
Mineola, NY • March 2025
“CO is no joke. Annual inspection complete. Worth every visit.”
★★★★★Mrs. Niamh Murphy
Rockville Centre, NY • December 2024
“Pellet stove running properly again after the service.”
★★★★★Mr. DeShawn Anderson
Elmont, NY • October 2024
“Annual gas fireplace service done. Ignition is much more reliable now.”
