Big old houses, big old chimneys

What these two areas have in common

The North Shore of Nassau and the Northern Valley of Bergen County look nothing alike on a map, but the chimney work is remarkably similar. Both are full of substantial homes built between the 1920s and the 1960s, many with two or three flues in a single stack, and nearly all of them now venting appliances they were never designed for.

  • Multi-flue stacks where one flue is swept for years and the others are never opened
  • Original clay liners cracked by decades of freeze–thaw, hidden until a camera goes up
  • High-efficiency gas boilers condensing inside masonry built for oil or coal
  • Crowns patched with sealant instead of being rebuilt, so the water keeps getting in
  • Large wooded lots on both sides of the river — uncapped flues fill with leaves and nests

What we do

Chimney services in Greenvale, NY

Every job starts with a camera and ends with photographs. Anything beyond the agreed scope gets quoted before it happens.

Chimney Sweeping

Soot and creosote removed under containment with a HEPA vacuum, so nothing lands on your floors. Photographs of the flue before and after, every visit. On a multi-flue stack we sweep and report on every flue, not just the one you use.

Camera Inspections

A full camera scan of each flue with a written report. Level 2 inspections for house sales, appliance changes, or after any chimney fire — the standard attorneys and home inspectors expect on both sides of the river.

Repair & Repointing

Eroded joints repointed, spalled brick cut out and replaced, failing crowns rebuilt in proper mortar rather than smeared with sealant. Colour-matched on the older homes where the brickwork is the point.

Liners & Relining

Stainless liners sized correctly for the appliance. This is the single most common job we do in both areas, because a modern boiler in a 1930s masonry flue is a slow-motion problem.

Learn more

Caps & Waterproofing

Stainless caps fitted and masonry sealed with a breathable water repellent. On a wooded lot a cap pays for itself the first autumn — it keeps leaves, rain and nesting animals out of the flue.

Dryer Vent Cleaning

A lint-packed duct run is both a fire risk and a standing energy cost. We clear the whole line and confirm the exterior flap still closes properly.

Why homeowners call us back

No theatre, no scare tactics, no invented emergencies

The quote comes before the work

We look, then we price, then we start. The invoice matches the number you agreed to, and anything extra is quoted and approved before a tool comes out.

Every flue, not just the obvious one

Most of these houses have more than one flue in the stack. We inspect and report on all of them, because the one nobody uses is usually the one with the problem.

You see your own flue

Camera footage and photographs from inside your chimney — not a stock image of somebody else’s problem used to sell you a rebuild.

No invented emergencies

If something can wait a season, we put that in writing. A good share of what we find is worth watching, not worth fixing today, and we would rather tell you that.

How it works

Four steps, no surprises

Tell us what is going on

Fireplace, boiler flue, dryer vent, a smell or a stain on the wall — a line or two is enough to start.

Pick a window that suits

A genuine appointment time, plus a text before the technician sets off. We run separate crews for the Long Island and Bergen sides, so you are not waiting on someone crossing the bridge.

Camera first, then work

We scan every flue before anything else. You see what we see, and you approve any additional work before it happens.

Written findings and honest advice

A report with photographs, and a clear line drawn between what is urgent, what is seasonal, and what is simply fine.

Questions we get every week

Straight answers

Do you cover both Long Island and Bergen County?
Yes, and with separate crews. Our North Shore work runs from Greenvale out through Glen Head, Roslyn, Glen Cove, Sea Cliff and Locust Valley. Our New Jersey work is centred on Tenafly and covers Cresskill, Demarest, Closter, Alpine, Haworth, Englewood Cliffs and Englewood. You are never waiting on a van stuck on a bridge — whoever is nearest to you is the crew you get.
How much does a chimney sweeping cost?
A standard sweep with a camera inspection for one fireplace sits in the normal range for Nassau and Bergen counties, but we price after seeing the setup rather than quoting a number down the phone. An open fireplace and a wood insert with an offset flue are genuinely different jobs. What we will commit to is that the quote arrives before the work and does not move afterwards.
Our chimney has three flues. Do you charge three times?
No. There is one call-out and one inspection fee covering the stack, and sweeping is priced per flue that actually needs it. What we will not do is inspect one flue, stay quiet about the other two, and let you find out about them years later. Multi-flue stacks are the norm in these towns and they get treated as one job.
We converted to a high-efficiency gas boiler. Does the chimney need anything?
Almost certainly yes, and this is the most common repair we carry out in both areas. Modern condensing appliances run cooler and produce far more moisture than the oil and coal systems these flues were built for, and that acidic condensate attacks masonry from the inside. A correctly sized stainless liner is the standard fix, and it is much better dealt with before a winter than during one.
Do you handle inspections for a house sale?
Yes. A Level 2 inspection is the right standard for a property transfer — a camera scan of every flue, examination of the accessible parts of the chimney, and a written report with images that attorneys and home inspectors accept in both New York and New Jersey.
Will you make a mess in the house?
No. Drop cloths go down, the fireplace opening is sealed, and a HEPA vacuum runs for the whole job. Cleaning up is part of the work, not an extra line on the invoice.
Our chimney has no cap. Does it matter?
It is the single most common issue we find, and on the wooded lots in both these areas it matters more than most places. Without a cap, rain goes straight down the flue, leaves pile up, and birds and squirrels nest in it until the flue is partly blocked. A cap is inexpensive, fits in one visit, and prevents a large share of the damage we later get called out to repair.
Are you licensed and insured?
Fully insured, and we will send the certificate ahead of the appointment if you want it on file. Our technicians are CSIA-trained and we work to NFPA 211.
