“Called DME Maintenance after my oil burner started backing up smoke. Douglas was out within two days, found heavy soot buildup in the flue, cleaned it out completely, and left a written report. Exactly what I needed before winter. Will use again.”
B. Flanagan. — Babylon, NY
“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.”
Anthony Ruggiero. — Lindenhurst, NY
“Used DME Maintenance for an oil-to-gas conversion liner. They handled everything — sizing, installation, and the documentation the gas company needed. No hidden charges, no surprises. Knowledgeable and professional.”
Rosemary Catanzaro. — Bay Shore, NY
“Had a blockage in my chimney — birds built a nest. DME Maintenance came out quickly, removed the nest, installed a stainless cap, and did a full cleaning. Fast, professional, fair price. Highly recommend to anyone in Smithtown.”
G. Marchetti. — Smithtown, NY
“My chimney was leaking every time it rained. DME Maintenance diagnosed a failed crown, repaired it and applied ChimSaver waterproofing. No leaks since. They also caught the flashing and fixed that too. Thorough and honest.”
Eileen Broderick. — Huntington, NY
“Three years of annual chimney cleaning with DME Maintenance. Always on time, always thorough, always leaves the place clean. The written inspection report is a nice touch — my insurance company asked for one and I had it ready.”
Sal Vitucci. — Islip, NY
