Modern Home Roofing & Chimney sweeps chimneys in 14 New Jersey counties under NJ HIC license 13VH13268400. We take soot and creosote out of the flue, because creosote is what burns in a chimney fire. While we are up there, we check the crown, cap, flashing and liner. Every sweep starts with a free inspection, photos and a written estimate.

Before the next fire

Why a flue needs sweeping

Every fire leaves soot and creosote on the inside of the flue. Creosote is what burns in a chimney fire. It builds up a little with every fire, faster when the wood is wet or the fire smolders, and you cannot see it from the room.

Once a year if you use it. That is how often NFPA 211, the national fire safety standard for chimneys and fireplaces, calls for a chimney to be inspected.

Signs the chimney is due for a sweep

  • The fireplace smells of smoke or tar, even when it is not in use.
  • It has been a year or more since the last sweep.
  • Black flakes falling into the firebox.
  • Smoke coming back into the room instead of going up the chimney.
  • You just bought the house and do not know when it was last swept.

A sweep takes out what has built up. It does not fix a cracked liner. If we find broken tile in the flue, we show you the photos and tell you what it needs. How a chimney liner job works

Process

How a chimney sweep works

A chimney sweep with us runs in six steps. The sweep itself is only part of it, because we check the whole chimney while we are there. Your written estimate lists how long the work will take.

  1. We look at the chimney first, free

    Before anything gets swept, we look at the fireplace, the damper and the top of the chimney, and photograph what we find.

  2. You get a written estimate

    What the sweep covers and the price, on paper. If we already see something that needs repair, it goes on the estimate as a separate line so you can decide on it.

  3. We protect the room

    Drop cloths go down in front of the fireplace and the opening is covered, and a vacuum runs while we sweep, so the soot stays out of the room.

  4. We sweep the flue

    We sweep the soot and creosote out of the flue, along with any nests, leaves or loose debris that have collected in it.

  5. We check the crown, cap, flashing and liner

    While we are up there, we photograph the top of the chimney, the flashing where it meets the roof, and the liner inside the flue.

  6. We go over the photos with you

    You see what came out and what the chimney looks like. If something needs repair, you get a written price. If nothing does, we tell you that.

What comes out

What a sweep takes out of the flue

This is what builds up inside a flue between sweeps. Most of it comes out with a brush. Some of it tells you something else is wrong.

  • Soot

    Fine black powder left by smoke. It narrows the flue a little at a time and is the first layer on the walls.

  • Flaky creosote

    Dry, crumbly deposits that build up from ordinary fires. This is what falls into the firebox as black flakes.

  • Tarry creosote

    Sticky and dark, from wet wood or a fire that smolders. It is harder to brush off and burns hotter when it catches.

  • Glazed creosote

    A hard, shiny coating on the flue walls. A brush does not take it off. If we find it, you see the photos and we tell you what it means for the chimney.

  • Nests and leaves

    Birds and animals build in a flue with no cap over it. They block the smoke from getting out.

  • Pieces of clay tile

    If broken tile comes down with the soot, the liner is cracked. A sweep cannot fix that.

After the sweep

What the sweep can turn up

Broken tile in the fireplace?

The liner is cracked, and that needs more than a sweep. See Chimney Liners.

Leaves, nests or water in the fireplace?

The cap is missing or the crown is cracked. See Chimney Caps and Crowns. A stain on the ceiling next to the chimney is usually Chimney Flashing.

FAQ

Chimney sweep questions

Still not covered? Call 732-682-9251 and ask. No cost, no script.

It depends on how many flues the chimney has, what you burn, and how much has built up since the last sweep. A fireplace used a few times a year and a wood stove run all winter are different jobs. We do not quote over the phone. You get a written price after we have looked.

NFPA 211, the national fire safety standard for chimneys and fireplaces, calls for a chimney to be inspected once a year if you use it, and swept when the inspection finds enough buildup to need it. If you burn wood all winter, that often means every year.

Creosote is what smoke leaves on the inside of the flue as it cools. It starts out as flaky soot and can build up into a sticky tar or a hard glaze. It is what burns in a chimney fire, which is why it should come out of the flue before it gets thick.

Usually it is creosote in the flue. The smell is often worse in summer, when humid air and air pulled down the chimney carry it into the room. A sweep takes out most of what causes it. If the smell stays after a sweep, we look for what else is going on.

Yes. While we are up there, we check the crown, cap, flashing and liner and show you the photos. If something needs repair, you get a written price for it. If nothing does, we tell you that, and you do not have to take our word for it.

It should not. Drop cloths go down in front of the fireplace, the opening gets covered, and we run a vacuum while we sweep so the soot stays in the flue and out of the room. We check the floor in front of the fireplace before we leave.

We sweep chimneys in Bergen, Essex, Hudson, Hunterdon, Mercer, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex, Union and Warren counties. If your town is in one of those, we can come out and look at it.
