Rookery Chimney & Flue · Halden Mill & the Sable Valley · Est. 1979

Forty-seven seasons of one rule: brush it, grade it, write it down.

Rookery sweeps and inspects chimneys across the valley — a Level 1 look every burning year, a Level 2 camera scan when a house changes hands, and a written card with the creosote grade on it before the van leaves. No reline has ever been sold from a ladder in this firm, and none ever will be.

Services & rates

The card, written first

Every household gets the same written card before anyone climbs anything, and the invoice repeats it line for line. NFPA 211 asks for a Level 1 look every burning year — creosote keeps no calendar but its own, and the card is how you keep ahead of it.

How it goes

The first visit, knock to card

The same sequence on every job — the only variable is your project.

  1. The knock

    Runners and sheets

    Floor covered hearth to door, HEPA vacuum running before the first rod goes up — the room should look untouched when we leave, and mostly it does.

  2. The brush

    Pass after pass

    Rod-and-brush to the termination, again and again, until the flue walls show bare clay tile or bare liner. What comes down is bagged and graded on the spot.

  3. The look

    Lamp, then camera

    The damper plate, the smoke chamber, the shelf — checked by name, camera where the lamp cannot reach. Second-degree plates and hairline cracks announce themselves here or not at all.

  4. The card

    Found, done, graded

    Creosote degree, draft reading, what was done, what next season needs — written at the kitchen table, priced off the card, dated and signed.

The valley says

Kept warm, kept honest

Three firms told this house it wanted a reline. Rookery brushed it, graded it first degree, re-seated a damper plate that had been stuck since the eighties, and wrote the whole thing on a card I could read in a minute. $319, all in, and the room stopped smelling of every fire since the war.
B. Calloway · Sweep and damper, Tanner’s Gate
The Level 2 scan at our sale found one cracked tile at the thimble and a starling nest above the shelf. Tile, nest, cap — and the video went to the buyer’s surveyor the same evening. The sale closed on Rookery’s report and nobody argued with a frame of it.
The Okonkwo-Reeve family · Level 2 scan at sale, Owlhollow
Grandad had this chimney swept by the firm before Rookery had the name. Same card, same price on the invoice as on the card, same bloke sweeping who did my parents’ place. In this trade that is the whole review.

Before the first fire

Straight answers

The five the shop phone answers every September. If yours is not here, the line runs seven to five, valley-wide.

How often does a chimney honestly need sweeping?

Every burning year — NFPA 211’s rule, and the valley’s weather agrees with it. A cord of seasoned hardwood lays down about an eighth of an inch of first-degree creosote; green or softwood doubles that. Your card carries your grade and your own interval, not a brochure’s.

What are the three creosote degrees?

First degree is flaky soot and brushes out. Second degree has hardened into shiny plates and gets the rotary head. Third degree is glazed tar — the fuel a chimney fire feeds on — and gets chemical treatment with a camera follow-up, because brushing glaze only polishes it. The card names the degree, every time.

Level 1, 2 or 3 — which one is mine?

Level 1 is the annual look with no tools beyond the brush. Level 2 is the camera scan, required at any sale, fuel change or after a flue fire. Level 3 opens masonry to reach what even the camera cannot, and is scoped only from what Level 2 filmed — rarer than the trade makes it sound.

My fireplace smells of last winter in July. Why?

Warm humid air falls down a cool flue and carries creosote odour back into the room — usually through a damper plate that no longer seats. Re-seating the plate is $140 and fixes most of it; a top-sealing damper closes the chimney like a biscuit tin and fixes nearly all of the rest.

Do you sell relines?

We install them — rigid 316Ti stainless, insulated, draw-tested — when the footage says the flue cannot be saved any other way. But the camera decides, you watch it decide, and four scans in five leave with the original flue and a clean bill. A firm that always finds a reline is not reading, it is selling.

The estate agent’s inspector wanted a full reline written into the purchase — four thousand and a fortnight of delay. Rookery put the camera down instead: one cracked tile at the thimble, a nest on the shelf, a damper plate seized open since who knows when. Tile replaced, nest cleared, plate seated, cap fitted — done for under six hundred, and the footage closed the argument. The card hangs in the deed drawer to this day.
