Keeping Manhasset Hills Homes Safe, One Chimney at a Time
Most homes here were built in the late 1950s and early 1960s. We know exactly what a chimney that age needs — and we clean, inspect, repair, and restore them so your family breathes easy and your fireplace burns bright.
We Know These Chimneys Because We Grew Up Fixing Them
Manhasset Hills homes went up mostly in the late 1950s and early 1960s, in neighborhoods like Shelter Rock Manor and along streets such as Crest Road. That means most chimneys here are pushing sixty years old. Brick settles. Mortar joints open up. Old clay liners crack.
If your chimney hasn't been inspected in a while, it's not a maintenance afterthought — it's the part of your house most likely to be quietly failing. A1 Chimney Services works on these chimneys every week. We know the housing stock, the weather patterns off the Sound, and the specific problems that show up in homes built during this era. We show up, we tell you exactly what we find, and we fix it right the first time.

Chimney Sweeping
Rotary brushes and a HEPA-filtered vacuum clear soot, creosote, and debris — nothing ends up on your carpet.

Case Studies
A few problems we've solved for Manhasset Hills neighbors recently.
Water Damage Traced to a Cracked Crown
A 1961 split-level had a crown cracked through in three places, letting water run down inside the flue for years. We poured a new reinforced crown with a proper drip edge. Result: no more staining on the fireplace surround, and the flue passed a Level 2 camera inspection clean.
Prevented a Carbon Monoxide Hazard
A homeowner near Clinton G. Martin Park called about a faint gas smell. Inspection found a partially blocked gas flue from bird nesting debris. We cleared it and tested for carbon monoxide before and after. Problem solved same day.
Same-Day Fix After a Nor'easter
After a spring storm, a Manhasset Hills homeowner found water stains spreading across a bedroom ceiling. The chimney flashing had lifted in the wind. We resealed it the same afternoon the call came in.
What Our Manhasset Hills Neighbors Say
Real, dated reviews from homeowners across Nassau County.
"Found a cracked crown during our inspection before we even asked. Sent photos, gave us a straight price, and had it rebuilt within the week. No pressure, no upsells."
"Called about a smoky smell on a Sunday and someone actually picked up. Tech was out first thing Monday, found a blocked flue, cleared it same visit. Would use again."
"Our chimney liner was original from the 60s and clearly cracked. They walked us through the video scan footage before quoting anything — appreciated the transparency."

Frequently Asked Questions
Most standard sweeps with a Level 1 inspection are priced based on flue count and accessibility. You'll get an exact price before we start — no charge, no obligation for the estimate.
Once a year for wood-burning fireplaces. Gas and oil systems still need an annual check, even without visible soot buildup, because blockages and corrosion aren't always obvious from the outside.
A sweep removes soot and creosote from the flue. Level 1 covers accessible areas for a routine annual check. Level 2 adds a video scan of the full flue and is required after any chimney fire, before buying or selling a home, or after changing your heating appliance.
White staining on the brick (efflorescence), a smoky smell in the house, visible cracks in the crown, rust on the damper, or crumbling mortar joints. Any of these mean it's time for an inspection, not a wait-and-see approach.
Less residue builds up, but the flues still need yearly checks. Gas appliances especially need a clear flue for safe carbon monoxide venting.

Yes. Storm damage, chimney fires, and blocked flues get priority scheduling, often same day.
