Stack and drain replacement, Worcester

The old iron stack inside your triple-decker, replaced floor by floor

The stack map

One pipe, three flats: the stack map of a triple-decker

From the roof vent to the street, one run carries the waste of every flat. Here is each stop on it, top to bottom, and what we check there.

  1. 01
    Roof

    Step 1: The vent: where the stack breathes

    The stack runs up through the roof so air can follow the water down. A vent stopped by a nest or by ice makes every drain below it gurgle.

    • Look for: gurgling when a neighbor flushes

    • Fix: clear or replace the vent run

  2. 02
    Third floor

    Step 2: Top flat: few fixtures, slow scale

    Little water passes here, so cast iron can look sound outside while it flakes inside. Sewer gas that reaches this flat usually means a vent or a cracked joint above the last fixture.

    • Look for: a sewer smell near the chase

    • Fix: replace the run from the roof down

  3. 03
    Second floor

    Step 3: Middle flat: the laterals and the offset

    The laterals are the sideways runs from each bath and kitchen into the stack. Where the stack steps over to clear the floor plan, that offset and its joints are where stains show up first.

    • Look for: a brown ceiling stain below a bath

    • Fix: new laterals and a straight run where we can

  4. 04
    First floor

    Step 4: Ground flat: the heaviest traffic

    Every flat above drains past this floor. A leaking hub joint in the wall shows as damp plaster, a stain in the ceiling or a smell that comes and goes.

    • Look for: plaster lifting beside the chase

    • Fix: open the chase, replace the run

  5. 05
    Cellar

    Step 5: Cellar: the foot of the stack

    The stack turns here and runs under the floor as the building drain. Scale, a crack or a sag shows on a camera put in through the cleanout, and shows at the house trap.

    • Look for: rust at joints, crust where it meets the floor

    • Fix: new foot, building drain and trap

  6. 06
    Street

    Step 6: Street: where your pipe ends

    The connection to the city's sewer is the city's. We replace your side only, and tell you in writing where ours stops.

    • Look for: backups after the cellar is clear

    • Fix: your side of the lateral, camera first

The signs

What a failing cast-iron stack looks like

Most signs appear in the flat beside or below the stack, not at the pipe. One sign is a reason to look. Two or three together are a reason to call.

  • A stained and cracked plaster ceiling in a room with orange walls

    A brown stain on the ceiling

    Often a leaking joint or a crack in a stack, a lateral or a drain above it. We trace it before anyone repaints.

    • Look at: the flat below a bath or kitchen

  • A ceiling with its plaster torn away to the wooden lath above a room

    Plaster lifting beside the chase

    Damp that has been there a while lifts paint and plaster. Where it sits against the stack, it is worth opening.

    • Look at: the wall the pipes run behind

  • A water-stained ornate ceiling corner with peeling paint and exposed pipes

    Peeling paint in a ceiling corner

    A corner that stains again after it is painted is telling you water is still arriving.

    • Look at: corners nearest the stack

  • White mineral streaks running down a stained concrete wall

    Streaks and crust in the cellar

    Rust-colored weeping at a joint, or a crust where the stack meets the floor. A dry crust still shows where water has been.

    • Look at: joints and the foot of the stack

Gurgling, a sewer smell, or drains that slow down on more than one floor at once are signs too, and they leave nothing to photograph.

Why it fails

Oakum, lead and iron: a joint built to last decades

Old stacks were put together in hubs. Tarred hemp called oakum was packed into each joint, then sealed with poured lead.

Those joints held for a long time. Over the years the iron scales and thins from the inside, and the lead and oakum dry and shrink. Sometimes one section is all that is bad, and the camera and the opened chase show which. If the iron is thin all the way, patching one joint only moves the leak.

What we look at before we recommend

  • Scale and pitting inside the pipe, by camera where there is a cleanout

  • Each joint on the run we can reach

  • The offsets, where the flow changes direction

  • What the other drains in the building are made of

What we do

Stacks and drains, and nothing else

We do not do bathrooms, kitchens or boilers. We replace what is inside the walls and under the cellar floor.

  • Stack replacement

    The full run, roof to cellar, with cast iron out and new pipe in. We plan it a flat at a time.

  • Section repairs

    When the camera and the opened chase show one bad section, we replace it and tell you what we saw in the rest.

  • Building drain and house trap

    The run under the cellar floor to the street, and the trap where it leaves.

  • Laterals and branch lines

    The sideways runs from each bath and kitchen to the stack, replaced while the wall is open.

  • Vents and roof penetrations

    New vent runs through the roof, sealed with the roofer's flashing or ours.

  • Camera inspections

    Through the cellar cleanout, with the findings written up and sent to you.

Sample comments

What owners say after the wall closes

“Three tenants, one stack. They sent a notice for each flat with the day the water would be off, and not one tenant called me angry.”

Bassem T.Landlord, Vernon Hill

“I live on the first floor. They covered the hall, opened the chase and showed me the old pipe before it went in the truck. It had a crack along one side I would never have seen.”

Kinga W.Owner-occupant, Main South

“The price came in writing and listed what it left out: plaster and paint. When the wall opened they sent a photo before doing anything extra.”

Jonel R.Owner of a three-decker, Grafton Hill

Before you call

Questions owners ask first

Do you replace the whole stack every time?

No. If the camera and the opened chase show one bad section, we replace that section and say what the rest looks like. If the iron is thin throughout, we recommend the whole run and show you why.

What will my tenants be told?

We send a notice letter for each flat with the day and the hours the water will be off. The letter has our office number on it, so tenants call us, not you.

Will I know the price before you start?

Yes, in writing. If the wall opens and the job changes, we stop, send you a photo and you decide.

Do you pull the permit?

Yes. The permit and the city's plumbing inspection are part of the job, and the permit fee is its own line on the estimate.

Do you work on the weekend?

The office is open weekdays. For a stack replaced in an occupied building we plan the work around when each flat can be without water.
