Boiler Demolition and Removal

The reason the company has the name it has. Cast iron sectionals, firetubes, watertubes, steam and hot water, condensing and copper-fin, from a basement in Lakewood to a 52-million-BTU firetube you could park a truck inside. It comes out in pieces, and the room is clean when it's gone.

What we remove

On the list

  • Cast iron sectional boilers
  • Firetube and Scotch marine boilers
  • Watertube boilers
  • Steam and hot water boilers
  • Condensing and copper-fin boilers
  • Commercial and residential water heaters
  • Flues, breeching, stacks and burners
  • Expansion tanks, pumps and the connected piping

How it goes

The way we do it

  1. 01

    Size it up

    Nameplate, sections or horsepower, the door it has to fit through, the stairs it has to climb. Residential and small commercial can usually be ranged by phone; everything else gets a walk.

  2. 02

    Protect and stage

    Floor protection down, hot-work permit posted, fire watch assigned, the path to the truck cleared.

  3. 03

    Take it apart

    Cast iron comes apart section by section; a 17-section boiler and its piping is a one-day job for us. Firetubes get cut into pieces sized for the path out. Burners, controls and flue come off first.

  4. 04

    Out, scrapped, swept

    Sections and cut pieces go out on skates, dollies or a winch, into the truck, to the yard. The pad and floor are swept before we leave.

Before we arrive

Your side of the line

Every proposal spells this out. It is what keeps the job safe and the price honest.

  • Gas, electrical and water disconnected, capped and locked out by your licensed trades. We don't touch live utilities.
  • Equipment drained and isolated before we arrive, unless draining is written into our scope.
  • Refrigerant recovered by an EPA-certified tech before we open anything, unless recovery is written into our scope (it can be).
  • Clear access to the room and a place to stage the trucks by the scheduled start.
  • Anything unusual about the site in writing before start day: tenant schedules, noise windows, hazardous-material reports, access restrictions.

Included

  • Disassembly and cutting
  • Rigging through existing building paths
  • Haul-away and scrap handling, value credited
  • Hot-work permit and fire watch
  • Floor protection and broom-clean turnover

Not included unless it is in the scope

  • Gas and electrical disconnection (licensed trades, before we arrive)
  • Draining and isolation unless written into scope
  • Asbestos abatement (see below)
  • Removal of the concrete pad unless quoted

Two 4-million-BTU firetubes, three days

Two 4M BTU firetube boilers, six expansion tanks, a heat exchanger and the mechanical-room piping cut at the agreed termination points. Sectioned, rigged through existing building paths and hauled, sequenced cleanly around the project's active abatement. Turned over to district standard.

Questions we get

Straight answers

How long does a boiler removal take?

A residential boiler or water heater is a day. A single accessible commercial boiler is one to two days. Two large firetubes with their tanks and piping ran three days on a recent school job. The proposal gives you a real number after the walk.

Does the old boiler have asbestos?

If it went in before the mid-1980s, assume the insulation, gaskets or pipe wrap might. Asbestos abatement is licensed work in Colorado and we don't do it. When it's present or suspected, a licensed abatement contractor clears it first, we coordinate schedules with them regularly, and then we take the boiler out. If we find suspect material mid-job we stop in that area and call you.

What do you do with the scrap?

Cast iron and steel go to the yard. The scrap value is already credited against your price, which is one reason the number is what it is. If your organization needs to keep the salvage, tell us before we bid and the job is priced accordingly.
